15 Mozilla Firefox tips & tricks you don't know

Undocumented tips help you get more from Firefox

Optimise Firefox for broadband

Believe it or not, Firefox is optimised for dial-up connections by default. You need to change some settings to get the browser's best performance over DSL, cable or other broadband links.

Before you change anything, back up Firefox's configuration file; return to the page "Better Default Google Search" and scroll down to "Back Up FireFox's 'Registry' " for details.

Next, open Firefox and press Ctrl, L to place the cursor in the address bar. Type about:config and press Enter. Then enter network.http in the filter field. Now make the following changes:

In the field of 'Preference Name' choices (click on the thumbnail at right to see the screen), double-click network.http.pipelining to set it to 'true'.

Firefox tip XXI

Next, double-click network.http.pipelining.maxrequests to bring up the 'Enter integer value' dialog box. Enter a higher number than the default 4; 15 works for me. Press Enter.

Firefox tip XXII

Double-click network.http.proxy.pipelining to set it to 'true'.

Right-click anywhere on the page and select New, Integer. Enter nglayout.initialpaint.delay and press . Set its value to 0 (zero), and press again.

Move your Firefox bookmarks and settings to a new PC

Amazingly enough, Firefox doesn't include an obvious, intuitive way to migrate the program's settings to a new PC. (I guess it's my job to tell you how to do it.)

On the old PC, close Firefox, select Start, Run (Start in Vista), type %appdata%\mozilla, and press Enter. The resulting Windows Explorer window will contain a folder named Firefox. Using a network or external drive, copy that folder to the new PC.

On the new PC, install, open and then close Firefox. If reopening it doesn't bring up the import wizard, close Firefox and open it again. When the wizard (which is useless in this situation) comes up, just press Cancel, and close Firefox.

Next, select Start, Run (Start in Vista), type %appdata%\mozilla, and press Enter. Rename the Firefox folder something like frominstall, and then copy the Firefox folder from the old PC to this location. Finally, open Firefox and relish your old, familiar settings.
