I have been using the new Firefox 3 for more than a month now on my laptop and I seem to have no problem at all. In fact I like the new notification system and it works quite faster than Firefox 2. The only thing that I did not like was that a lot of extension that were made for FF 2 are not compatible with FF3. Even though there is not much difference in the way they are made.

But my friend Vivek has posted a solution on his blog with screenshots on how to cheat this thing in Firefox 3. It involves tweaking the extensions.checkCompatibility paramenter in the about:config section of the new Firefox and turning it off. Its very simple and now I can use my mouse gestures again. Wohoo.
