How do I reinstall the previous version of Firefox (v.3.6.16)?


I just installed Firefox 4. Norton Toolbar (5.5) is not compatible. Therefore, I would like to revert back to the previous version of Firefox (I believe it was 3.6.16) but do not know how to do it.

I hate it too. Unnecessarily complicated. The features I liked and used a lot disappeared and I can't even find them now. I reverted back to 3.6 which works fine for me. We should be able to keep the version we prefer.

I do not have any problem with the internet service. iYogi is a service that I have much confidence in and they have handled all my problems quite sufficiently.

Good for iYogi!

Hi , On vista , click start at end of screen , type mozilla, and your 2 versions appear, click on firefox 3.6 and install, that's it , your back to normal, lost nothing, and every thing works the way it was !!! good luck, fire fox is brill, but don`t know why 4 is not working well, 3.6 is great !
