Tips, Tricks, & Tweaks


Mozilla Firefox













Mailto Links

My Add-ons

Profile Manager
















As usual, nothing out of the box is good enough.  Change is good especially if and when it improves things.  These are basically my notes gathered from Googling around for customizations wanted and used regularly.  Some of the below may be done via the registry, if comfortable, go for it, if not, do not!  Either way, I’ll try to help!


Use at your own risk!


Happy Tweaking!


Windows 7 Home Premium 64 Bit SP1, Mozilla Firefox, on an Acer Aspire 5150 Laptop

AMD Phenom(tm) II N660 Dual-Core Processor (self-upgraded from single-core V120)

3.00 GHz, 8GB RAM, 250GB HDD



I customize the toolbar by dragging & dropping things so as to use the minimal amount of vertical screenestate.

This file sets the display rules for various elements in Firefox which allows you to customize the way Firefox looks.  It’s located in the sub-folder called ‘chrome’ in your profile folder (your Profile Folder is here: press the Alt key to show the menu bar items, then go to Help + Troubleshooting Information + Open Containing Folder).  There’s an example file that exists there by default, it’s called userChrome-example.css.   Basically, just exit Firefox, rename that file to userChrome.css, open it with Notepad, delete everything in it and paste the entries below into it (it begins with /* and ends with }).  Save the changes, close the file and open Firefox to see the changes.  To revert back, simply rename it to its original name.  Oh, don’t forget to first install all the Add-ons above.
