Fixing addons for firefox can be really easy, or not. Sometimes its as simple as changing the version number in the script. This has worked for everything I've installed except imagebot.
Stupid little guide on how to update plugins for those that don't know (Keep in mind, this is assuming there wasn't any major change in Firefox.)
Images in spoilers for those that are really pc-tarded and cant figure it out
1: Download said addon by rightclicking and save as. This will download an XPI File, they are just like .zip files, so open them with Winrar. See picture 2

2: Open Install.rdf
3: Find the firefox tag, and find the Min/Max version of the addon IE:
Code:
<!-- FireFox -->
<em:targetApplication>
<Description>
<em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
<em:minVersion>0.7</em:minVersion>
<em:maxVersion>2.0a3</em:maxVersion>
</Description>
</em:targetApplication>
Change the max version to "3.*" The * is a wildcard.
