Problems with Add-ons in Firefox 3.6

I upgraded my browser to FireFox 3.6 and I have never had more problems with add-ons than I do now. In fact, it took a bit of research for me to figure out why they weren't working and then to ultimately fix them.

So I downloaded several add-ons. Google Toolbar, FireBug etc.... and nothing would ever ever show up under my Tools Menu in Firefox.

I ran across this great little tip today that worked:

For Windowx XP, From the Start Menu, choose Run and type in:

%APPDATA%\Mozilla\Firefox\Profiles

It will go to a directory similar to:
C:\Documents and Settings\mindy\Application Data\Mozilla\Firefox\Profiles\b6zwdmym.default

There you will find 4 files that start with the name extensions.

Now close completely out of Firefox. Make sure all windows are closed and the application isn't running anywhere on your machine. Go to the directory mentioned above and change extensions.ini, extensions.cache and extensions.rdf to something like old_extensions.ini, old_extensions.cache and old_extensions.rdf

Re-start Firefox and you will likely find many of the add-ons you thought you already installed already there. If you received a -203 error when trying to download add-ons, you'll need to re-install those add-ons but this time they will work.

Enjoy!
