Best Notepad tricks and hacks

The notepad tricks showing here are very small tricks which we can do by batch coding and vbs etc..,By this post you will know how powerful is Batch coding and how fun it is working with batch coding.

 1. Bush Hid the Facts/This App Can Break

This is one of the most popular notepad tricks because of its mysterious nature. In order to get an idea as to what this trick does, just follow the steps given below:
  • Open Notepad.
  • Type “BUSH HID THE FACTS” or “this app can break” (without quotes).
  • Save that file with any name and close it.
  • Open It Again to see the magic.
Reason For This Behavior: It is known as the 4335 Rule. It means that if we enter four words separated by spaces, wherein the first word has 4 letters, the next two have three letters each, and the last word has five letters. Then Notepad Automatically hides the text into unknown code.

2. World Trade Center Attack Trick

28 Coolest Firefox About:Config Tricks


You may have installed countless add-on in Firefox to enhance your using experience, but if you want to get the most out of Firefox, you really have to hack your way into theabout:config.


The about:config page contains most (if not, all) of Firefox configuration options. It is so far the most effective, and the most powerful way to tweak and enhance your Firefox performance. Here are 28 of the popular tweaks.

Accessing your about:config page
In your Firefox, type about:config in the address bar.



You will be shown a warning page. Click the “I’ll be careful, I promise!” button to proceed.






On the main page, you will see a long list of configuration entries. Enter the name of the key you want to update in the “Filter” field. The list will narrow to only the entries that match your keyword as you type.

To modify the value, simply double click on the entry value field and update the entry. That’s all!
Isn’t that simple? Now, let’s get to the tweaking.
1) Adjust the Smart Location Bar’s Number of Suggestions

In Firefox 3, when you start typing in the location bar, a drop-down list of suggestion URLs will be shown. If you want it to show more than 12 suggestions (12 is the default), you can adjust the browser.urlbar.maxRichResults keys and get it to show the number you want.



Config name: browser.urlbar.maxRichResults
Default: 12

Modified value: Set to your desired number of suggestion. If you want to disable it all together, set it to -1

2) Disable the session restore function
Firefox 3 automatically saves your session every 10 secs so that whenever it crashes, it can restore all your tabs. While this is a useful feature, some of you might find it irritating. To disable this function, toggle the value of browser.sessionstore.enabled to False
Config name: browser.sessionstore.enabled

Default: True
Modified value: False if you want to disable the session restore function

3) Adjust the Session Restore Saving Frequency
Same as above, if you decided to keep the session restore feature on, but want to reduce the session saving frequency, change the value of browser.sessionstore.interval so that Firefox will save the session at a longer interval.


Config name: browser.sessionstore.interval
Default: 10000 (in msecs, equivalent to 10secs)

Modified value: Set it to your desired value. 1000 means 1 sec and 60000 means 1 minute.


4) Enable Advanced Color Profile Support


Firefox has this advanced color profile features that display higher image quality. It is not enabled by default as it has a negative effect on the performance of the browser. If you are concern with the image quality rather than the performance, you can activated it via the gfx.color_management.enabled setting


Config name: gfx.color_management.enabled
Default: False

Modified value: True (if you want to activate the color profile support feature)


5) Disable Antivirus Scanning


This is mainly for Windows users. By default, Firefox 3 automatically scan the downloaded file with the default anti-virus application to make sure it is free of virus. If you download a big file, it could take a long time for the whole scanning process to complete. To increase the performance of the browser, you might want to consider disabling the anti-virus scanning via the browser.download.manager.scanWhenDone key.


Config name: browser.download.manager.scanWhenDone

Default: True

Modified value: False (if you want to disable it)


6) Configuring The Scrolling Tabs


When you opened many tabs, Firefox will not keep on reducing the tab width. Instead, it shows a scrolling bar so that the min width (100px) is conserved and you can scroll to find your tabs. If you are those who don’t like the scrolling tab function and prefer Firefox to show all the tabs, regardless how small it is, you can set the value ofbrowser.tabs.tabMinWidth to 0 to disable it. Similarly, if you want Firefox to display more tabs before showing the scrolling button, you can reduce the default value to a lower value, say 75 pixels.





Config name: browser.tabs.tabMinWidth
Default: 100

Modified value: 0 if you want to disable the scrolling functions, other values to set the min width value


7) Show/Disable Close button on Tabs


Some people love to see the Close (the red X) button on every tabs, but some hate it. Whatever is it, you can configure it to your preferences via thebrowser.tabs.closeButtons setting.





Config name: browser.tabs.closeButtons
Default: 1

Modified values:
0 - display a close button on the active tab only
1- display close buttons on all tabs
2- don’t display any close buttons
3- display a single close button at the end of the tab strip


 Extend Scripts Execution Time


In Firefox 3, a script is only given 10 seconds to respond, after which it will issue a unresponsive script warning. If you are hooked on a slow network connection, you might want to increase the script execution time via dom.max_script_run_time to cut down on the frequency of the no script warning.


Config name: dom.max_script_run_time

Default:10 (in secs)

Modified value: 20, or any values greater than 10


9) Handling JavaScript Popups


When you come across a site that executes a javascript open new window function, and if the popup window is without all the usual window features, i.e. back/forward/reload buttons, status bar etc, Firefox will automatically treat it as a popup and will not open it as a new tab. However, if you find this to be a nuisance and wanted to open all new windows in a new tabs, you can specify it via thebrowser.link.open_newwindow.restriction setting.


Config name: browser.link.open_newwindow.restriction

Default: 2 - Open all JavaScript windows the same way as you have Firefox handle new windows unless the JavaScript call specifies how to display the window
Modified values:
0 – open all links as how you have Firefox handle new windows
1 – do not open any new windows
2- open all links as how you have Firefox handle new windows unless the Javascript specify how to display the window


10) Enable Spell Checking In All Text Fields


The default spell checking function only checks for multi-line text boxes. You can get it to spell-check for single line text box as well.


Config name: layout.spellcheckDefault

Default: 1 (spell checker for multi-lines text boxes only)

Modified values:
0 – disable the spell checker
2 – enable the spell checker for all text boxes


11) Open Search Box Results In New Tab


When you search using the search box at the top right hand corner of the browser, it will display the search results in the current tab. If you don’t want the search to interfere with your current tab, you can tweak the browser.search.openintab to make it open in a new tab.


Config Name: browser.search.openintab
Default: False

Modified value: True (open search box results in new tab)


12) Lower The Physical Memory Used When Minimized


This tweak is mainly for Windows users. When you minimize Firefox, it will send Firefox to your virtual memory and free up your physical memory for other programs to use. Firefox will reduce its physical memory usage, when minimized, to approximately 10MB (give or take some) and when you maximize Firefox it will take back the memory that it needs.


The preference name does not exist and needs to be created.


Right click on the background and select New->Boolean.


Enter the name when prompted: config.trim_on_minimize

Enter the values: True


13) Speed up your Firefox


Several tweaks required for this


Config name: network.http.pipelining

Default: False

Modified value: True


Config name: network.http.proxy.pipelining

Default: False

Modified value: True


Config name: network.http.pipelining.maxrequests
Default: 4

Modified value: any value higher than 4, but not more than 8


Config name: network.http.max-connections

Default: 30

Modified value: 96


Config name: network.http.max-connections-per-server

Default: 15

Modified value: 32


14) Increase/Decrease the Amount of Disk Cache


When a page is loaded, Firefox will cache it into the hard disk so that it doesn’t need to be download again for redisplaying. The bigger the storage size you cater for Firefox, the more pages it can cache.


Before you increase the disk cache size, make sure that browser.cache.disk.enabledbrowser.cache.disk.enable is set to True.


Config name: browser.cache.disk.capacity

Default: 50000 (in KB)

Modified value:
0 – disable disk caching
any value lower than 50000 reduces the disk cache
any value higher than 50000 increases the disk cache.


15) Select all text when click on the URL bar


In Windows and Mac, Firefox highlights all text when you click on the URL bar. In Linux, it does not select all the text. Instead, it places the cursor at the insertion point. Regardless which platform you are using, you can now tweak it to either select all or place cursor at insertion point.





Config name: browser.urlbar.clickSelectsAll

Modified value:
False – place cursor at insertion point
True – select all text on click


16) Autofill Address in URL Bar


Other than the smart location feature, you can also get your URL bar to autofill the address as you type the URL.





Config name: browser.urlbar.autofill

Default: False

Modified value: True (Have Firefox autofill the address as you type in the URL bar)


17) Same Zoom Level For Every Site


Firefox remembers your zoom preference for each site and set it to your preferences whenever you load the page. If you want the zoom level to be consistent from site to site, you can toggle the value of browser.zoom.siteSpecific from True to False.


Config name: browser.zoom.siteSpecific

Default: True

Modified value: False (enable same zoom preferences for every sites)


18) Setting your zoom limit


If you find that the max/min zoom level is still not sufficient for your viewing, you can change the zoom limit to suit your viewing habits.


Config name: zoom.maxPercent

Default: 300 (percent)

Modified value: any value higher than 300


Config name: zoom.minPercent

Default: 30 (percent)
value: any value


19) Configure Your Backspace Button


In Firefox, you can set your backspace to better use by getting it to either go back to theprevious page or act as page up function.


Config name: browser.backspace_action

Default: 2 (does nothing)

Modified value:
0 – go back previous page
1- page up


20) Increase Offline Cache


If you do not have access to Internet most of the time, you might want to increase the offline cache so that you can continue to work offline. By default, Firefox 3 caches 500MB of data from supported offline Web apps. You can change that value to whatever amount of your choice.


Config name: browser.cache.offline.capacity

Default: 512000 (in KB)

Modified value: any value higher than 512000 will increase the cache value


21) Auto Export Firefox 3 bookmarks to bookmarks.html


Unlike the previous version, Firefox 3 backup the bookmarks file in places.sqlite rather than the usual bookmarks.html. Since bookmarks.html allows us to export and sync our bookmarks with other browser, it will be very useful if Firefox 3 can backup the bookmark to the bookmarks.html as well.


Config name: browser.bookmarks.autoExportHTML

Default: False

Modified value: True (auto export bookmarks file to bookmarks.html)


22) Disable Extension Compatibility Checks


This is useful if you want to use an extension that is not supported by your version of Firefox badly. It is not recommended, but you can still do it at your own risk.


Right click and select New->Boolean. Enter extensions.checkCompatibility in the field. Enter False in the next field.


Right click again and select New->Boolean. Enter extensions.checkUpdateSecurity into the field and enter False into the next field.


23) Disable Delay Time When Installing Add-on


Everytime you wanted to install a Firefox add-on, you will have to wait for several secs before the actual installation starts. If you are tired of waiting, you can turn the functionsecurity.dialog_enable_delay off so that the installation will start immediately upon clicking.





Config name: security.dialog_enable_delay

Default: 2000 (in msec)

Modified value:
0 – start installation immediately
any other value (in msec)

24) View Source in Your Favorite Editor

This is very useful for developers who are always using the ‘view source‘ function. This tweak allows you to view the source code in an external editor.

There are two configuration need to be made:

Config name: view_source.editor.external

Default: False

Modified value: True ( enable view source using external text editor)

Config name: view_source.editor.path

Default: blank

Modified value: insert the file path to your editor here.


25) Increasing ‘Save Link As‘ timeout value

When you right click and select the ‘Save Link As…‘, the browser will request the content disposition header from the URL so as to determine the filename. If the URL did not deliver the header within 1 sec, Firefox will issue a timeout value. This could happen very frequently in a slow network connection environment. To prevent this issue from happening frequently, you can increase the timeout value so as to reduce the possibility of a timeout.


Config name: Browser.download.saveLinkAsFilenameTimeout

Default: 1000 (1 sec)

Modified value: any value higher than 1000 (value is in msec)

26) Animate Fullscreen Toolbar Collapse mode

In Firefox’s fullscreen mode, toolbars and the tab strip are hidden at the top of the screen and only shown on mouseover. To draw attention to this, there is an animation of the toolbar sliding upwards and off-screen when fullscreen mode is toggled on. For performance issue, the animation of the collapse of the toolbar only appear for the first time. For some reason that you may love/hate the animation, you can adjustBrowser.fullscreen.animateUp to switch it on/off for every collapse.


Config name: Browser.fullscreen.animateUp

Default: 1 (animate the toolbar collapse only the first time)

Modified value:
0 -disable the animation
2- enable the animation for every collapse


27) Autohide Toolbar in Fullscreen mode

In fullscreen mode, the toolbar is set to autohide and appear upon mouseover. If you have a need to view the toolbar at all time, you can toggle the value ofbrowser.fullscreen.autohide to False to always show the toolbar.

Config name: browser.fullscreen.autohide

Default: True (always autohide)

Modified value: False (always show the toolbar)

28) Increase Add-On search result

If you go to Tools->Add-ons->Get Add-ons and perform a search there, Firefox will only fetch and display 5 matching results. If you want Firefox to show more than 5 results (say 10), you can adjust extensions.getAddons.maxResults to get it to display more results.

Config name: extensions.getAddons.maxResults

Default: 5

Modified value: any value more than 5
