I have Norton 360 and it's not compatible with the upgrade to Firefox 4? How do I get Norton activated now for the internet?

more options

I received a notice that I should upgrade to the Firefox 4. After I did the upgrade I then got a notice that Norton wasn't compatible with the the upgrade. How do I go about getting my Norton Security to work with this upgrade. So right now I have nothing in which is protecting my computer while surfing. Nothing against your product BUT I want what I already had/have to be the one protecting my computer. So what needs to be done so I can have my existing computer security to work with this upgrade. Otherwise I'll go back to the previous version which did work with Norton.

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

I do not know about the time scale for updates for other Norton products. Pending the update by Symantec, if you want to use the Norton add-ons you will need to downgrade to Firefox 3.6.

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.

Norton should still be protecting your computer from virus attacks, it's just their silly little extensions that are out of date.
