Firefox 3 Add-on Assistance

I migrated to Firefox 3 and realized my newly found MinimizeToTray program was not updated yet for the new browser version. After searching the Add-on reviews/help section, I thought I found the answer – but it didn’t work. I then found the following post from the Ultimate Chicken on how to get old Add-ons to work in Firefox 3 (slightly modified/extended for my blog post):

1. Save the .xpi file to your desktop
2. Rename the .xpi extension to .zip
3. Extract the contents of the .zip file
4. Open the newly extracted folder
5. Grab the install.rdf file and put it on your desktop
6. Delete the extracted zip folder and its contents
7. Open the install.rdf file with a text editor (Notepad)
8. Change the Mozilla Firefox entry from 2.0.0.* to 4.0.0.*
9. Do a plain save so the file retains the .rdf extension
10. Go to your desktop (updated install.rdf and original .zip s/b there)
11. Drag and drop the install.rdf file over the .zip file
12. Click yes to overwrite the old install.rdf file
13. Rename the .zip extension back to .xpi
14. You should now be able to install the .xpi in Firefox

Hopefully this will work for you if you are in the same sitaution.
