One of the only gripes I’ve had with Firefox is that every new version number knocked out several extensions. Thus, I would have to wait for the extension’s author to post an updated version. Typically, the only change is an update to the version of Firefox that the extension supports (0.8 to 0.9 to 0.10 to 1.0…) Now that 1.0 is out, this should happen far less frequently, but, of course, 1.0 breaks extensions that I want to use. So, a quick bit of research lead me to this forum post which provides easy to follow directions for fixing these ‘broken’ extensions:
1. Close Firefox
2. Edit the file Extensions.rdf contained in %appdata% > MozillaFirefox > Profiles > randomname > extensions
(on my Windows box, I edited C: > Documents and Settings > Alex Jones > Application Data > MozillaFirefox > Profiles > r0cy7i5r.Alex > extensions > Extensions.rdf )
3. Change every occurrence of maxVersion=”0.10″ to maxVersion=”1.0″
4. Start Firefox and look at your extensions menu. If the extensions are still grayed out, right-click on each one and click on ‘Enable’. Once you restart Firefox, these should be available as well.
