How do I switch back to 3.6? I use Norton 360 and it doesn't work with Firefox 4. I have uninstalled 4 and try to reinstall 3.6 from my downloads but it deleted 3.6 exe when it installed 4. I WANT 3.6 BACK.

Norton isn't supported on Firefox 4. I don't trust ANY web browser that I can't use Norton on. I had no complaints with it when I had Firefox 3.6. I want to reinstall 3.6 but can't. I have looked all over for a download but every one comes back to Firefox 4.

Symantec need to update their Firefox add-ons so that they are compatible with Firefox 4. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US

To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.

You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.

To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.

Thanks for your response. I will try it. I hope Symantec can get that out soon. I like the new Forefox and will reinstall it as soon as I can use it with with my antivirus.
