And making Firefox 3 ignore extension compatibility checking is wrong!
Firefox 3 is really close final release. Many of you have started using Firefox 3 for your daily browsing, as have I. You might discover that some of the extension you love have not been updated to Firefox 3 or maybe just not updated to the latest beta. So you search the web and find posts and tools for magically making old extension “work” in Firefox 3.
The Lifehacker post says “Make Your Extensions Work with the Firefox 3 Beta.” Nightly Test Tools adds a button to “Make all compatible.” This is snake oil my friend and you could be faced with nasty consequences.
These methods DO NOT make your old extension updated to work in Firefox 3. They turn off Firefox’s builtin extension version checking system. These methods should only be used for testing, not everyday browsing.
More than a few of the top-crashing bugs (reported when Firefox crashes) are due to users running old, incompatible add-ons. Please, turn on the compatibility checking. If you can’t wait for your favorite add-on to be updated, maybe it’s time to look for a new add-on. Firefox 3 is the leanest, fastest, most feature packed version we have ever released. Don’t foul it up with old crappy add-ons.
