hey all, well im having problems with addons with mozilla firefox.

everytime i try to install a browser theme for it, it gives me an error like this:


"firefox could not install the file at

http:/addons.mozilla.org/en-US/firefox/downloads/file/22175/aero_fox-1.0.5-fx.jar

because: Unexpected installation error
review the error console log for more details.
-203"

im on vista right now, could that have some sort of role? lol jk
or not?

I had a similar problem with Firefox when I first when I 1st started with Vista. You can check out the following web page for some assistance: Unable to install add-ons
Just in case here is a summary of what the page says:
Unexpected installation error -203

This error message can be caused by corrupted configuration files on your computer. To resolve, see Corrupt extension files below.

Corrupt extension files

Corrupt extension configuration files can cause problems when trying to install an extension. Deleting these files will make Firefox recreate them (removing any corruption) the next time it starts. You won't lose your extensions or their settings by deleting these files.

1. From the menu at the top of the Firefox window, select File and then select the Exit menu item.
2. Go to your profile folder. (To find your profile folder type %APPDATA%\Mozilla\Firefox\Profiles\ in the start search box without pressing enter. One or more profile will appear on the top left of the start menu, pick one and click on it.)
3. Delete the following files within the profile:
* extensions.ini
* extensions.cache
* extensions.rdf
4. Restart Firefox.

Good luck and happy browsing
