Firefox Configuration Tips and Tricks .
Use the Firefox browser :
If you type about:config in address bar of firefox, it will open its configuration page, that allows to change a lot of settings.
Here I'm presenting some settings, that can be configured. These tweaks have been tested on high speed networks and cable, they might need to be tweaked for slower connections.
You can follow any of these two steps to config your browser:
1. Use the about:config screen which lets you add, modify or reset values or
2. Manually add all of these hacks to the prefs.js.
Option 1:
Type about:config at the location/url bar, this will list all current references, and you can change the settings listed below.
Option 2:
*
Exit out of the browser completely, because if you don't close the browser, it'll overwrite the settings to default.
*
Find your prefs.js file (usually in Drive:\Documents and Settings\USER_NAME\Application Data\Mozilla\Firefox\Profiles\... directory in Windows XP).
*
Backup your prefs.js file.
*
Ccopy and paste the hacks listed below at the BOTTOM of the file.
*
Save the prefs.js file and restart your browser .

There are Three files, that can be edited to configure Firefox!
user.js :-
Used to change various preferences.
userChrome.css :-
Used to change the appearance of the browser.
userContent.css :-
Used to change the appearance of web pages.
All these files are plain text files stored in your profile folder, and can be edited using a standard text editor, such as Notepad on Windows and gedit or kate on Linux.
The Profile Folder :
The profile folder is where Firefox saves all your settings and refers to a location on your hard drive.
On Windows XP/2000, the path is usually
%AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\, where xxxxxxxx is a random string of 3 characters. Just browse to C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\ and the rest should be obvious.
On Windows 95/98/Me, the path is usually C:\WINDOWS\Application Data\Mozilla\Firefox\Profiles\xxxxxxxx.default\ .
On Linux, the path is usually ~/.mozilla/firefox/xxxxxxxx.default/ .
On MacOS X, the path is usually ~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/ .
Firefox is capable of handling more than one user and thus, more than one profile. The path examples above refers to the default profile that is automatically created when you start Firefox for the first time. You can manage any number of profiles by using the Profile Manager.
%AppData% is a shorthand for the Application Data path on Windows 2000/XP. To use it, click Start > Run..., enter %AppData% and press Enter. You will be taken to the "real" folder, which is normally C:\Documents and Settings\[User Name]\Application Data.
user.js :-
This is the main preferences file for Firefox and is located in you profile folder. The file does not exist by default, so you need to create it before you can start adding your preferences.
userChrome.css :-
This file sets the display rules for various elements in the Firefox user interface and is located in the sub-folder called chrome in your profile folder. As with user.js, this file does not exist by default, so you need to create it before you can start adding your preferences. There's actually an example file that exists by default, called "userChrome-example.css". Basically, you can just rename that file by removing the "-example" part.
userContent.css :-
This file sets the display rules for web content and is located in the sub-folder called chrome in your profile folder. As with user.js, this file does not exist by default, so you need to create it before you can start adding your preferences. As with userChrome.css, there is an example file that exists by default, called "userContent-example.css". Basically, you can just rename that file by removing the "-example" part.
Mozilla Firefox Optimizer
To avoid getting timeout when viewing any web site in firefox:
Get this Mozilla Optimizer, it keeps the connection alive....
http://www.softpedia.com/get/Tweak/Browser...Optimizer.shtml
Mozilla Optimizer improves the browsing speed in all browsers based on the
Gecko Rendering Engine (GRE) like Mozilla, Phoenix, Mozilla Firebird and
Mozilla Firefox as well as Netscape 6 and Netscape 7. All optimizations can be applied manually, this tool simply automates this procedure!
You can also do the same manually, by adding following lines (replace if they already exist) in prefs.js file:
user_pref("nglayout.initialpaint.delay", 100);
user_pref("content.notify.ontimer", true);
user_pref("content.notify.interval", 100000);
user_pref("content.notify.backoffcount", 5);
user_pref("network.http.pipelining", true);
user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 4);
user_pref("network.http.max-persistent-connections-per-server", 2);
Firefox Tabbed Browsing Tips and Tricks
1. Trick to Reveal More Tab/Window Options :
There are some hidden options for the Tabbed Browsing that will allow you to force links that open new windows to open in the current or a new tab. First, add the following code to your user.js file:
// Reveal more tab/window options:
user_pref("browser.tabs.showSingleWindowModePrefs", true);
Restart Firefox and go to Tools > Options... (Edit > Preferences... under Linux and MacOS X), select Advanced and click on Tabbed Browsing.
2. Remove the close button from the tab bar :
You can remove the close button from the tab bar by adding the following code to your userChrome.css file:
/* Remove the close button on the tab bar */
.tabs-closebutton {
display: none !important;
}
You can still close tabs by right clicking on them and select Close Tab, or by pressing Ctrl+W
3. Remove items from the main menu :
Some people like to place all their toolbar items on the same row as the menu. In order to save horizontal space, you can remove top menu items that you don't use. Add the following code to your userChrome.css file:
/* Remove the Go and Help menus
(These are just examples. Try changing "Go" to "Edit" or "Bookmarks") */
menu[label="Go"], menu[label="Help"] {
display: none !important;
}
Firefox Change Cursor Tips and Tricks
1. Change the cursor for links that open in new window :
This neat trick will change the mouse pointer when you hover it over links that will open a new window. Add the following code to your userContent.css file:
/* Change cursor for links that open in new window */
:link[target="_blank"], :visited[target="_blank"],
:link[target="_new"], :visited[target="_new"] {
cursor: crosshair;
}
2. Change the cursor for JavaScript links :
This tip will change the mouse pointer when you hover it over links that will perform a JavaScript command. Add the following code to your userContent.css file:
/* Change cursor for JavaScript links */
a[href^="javascript:"] {
cursor: move;
}
Firefox Some Advanced Tips for Tabbed Browsing
Home Page as tabs :
Instead of just one web page as your homepage, you can make your home page several pages. Select your favorite web sites and open them in a set of tabbed windows. Go to Tools -> Options and select 'General'. Under 'Home Page', press the 'Use Current Pages' button. Now when you hit the Home button on the Navigation toolbar, your favorite web sites will load with just one click.
Bookmarking a set of tabs :
You can bookmark a set of tabs when selecting 'Bookmark This Page' or Ctrl+D Check the 'Bookmark all tabs in a folder' checkbox to store all the tabs in the current window into a Bookmark Folder.
More shortcuts :
While it's easy to select tabs with a mouse, you can also cycle through tabs using the keyboard: use Ctrl+PgUp (or Ctrl+Tab) and Ctrl+PgDn (or Shift+Ctrl+Tab). You can also select the first tab by pressing Ctrl+1, and so on up to the 9th tab with Ctrl+9. If you have a middle mouse button, click it on a tab to close the tab.

Some more Tips about Firefox
1.
We always backup our Favorites in Firefox, so that whenever we reinstall the browser we can safely restore them without ne problem. (If u don't know how to backup favorites? Goto: Bookmarks -> Manage Bookmarks..., It'll open Bookmarks Manager. Then goto: File -> Export... & save them.)
Now come to the point.
The thing is that whenever we reinstall firefox we have to restore them by applying same process as we do 4 backing up them (use Import instead of Export). And one more thing we HIV to also backup our current bookmarks when we r planning to reinstall the browser.
So the trick is that we can define our custom Bookmark path in firefox , so that we don't need to import or export them.
Type about:config in address bar of browser, right-click & create a new String value, named browser.bookmarks.file and set its value to the path where u have backed up your favorites. Now firefox always update it automatically whenever u add or delete your bookmarks, so no need to continuously take backup.
2.
Second trick is very useful. Many times u have noticed that when u minimize the firefox windows & again restore it, it takes some time to restore. This trick reduces this delay.
Same thing, type about:config in the address bar of firefox, right-click & create a new Boolean value, named config.trim_on_minimize & set its value to false. It'll prevent delays when restoring the window.
