Turn off Firefox add-on compatibility check
Been trying to live the life trying out the Firefox 4 beta and found yourself annoyed with add-ons no longer working? Why not try turning that check off?
The method is relatively simple, but don’t screw up or it won’t work. Open Firefox and enter
about:config
in the URL bar. You’ll get warning telling you that you could break things, go past it. As a side note, you are hereby warned you could break things, but don’t worry. After all, your hand is basically being held and you want that particular add-on back, don’t you? Next, we’re going to add a new key-value pair. Right click the list and select New -> Boolean. You’ll be asked for a name, follow this scheme
extensions.checkCompatibility.version
Version can be 3.6, 4.0a (a = alpha), 4.0b (b = beta), 3.5, … Fill the version in that you are using. Eg for my Firefox 4.0 beta 6, I had
extensions.checkCompatibility.4.0b
As boolean value, enter false. This should force the add-on to be allowed to install by getting rid of the compatibility check. Keep in mind that there’s a reason such a check is in effect in the first place. Add-ons “forced” to install this way aren’t guaranteed to work properly.
