Norton Security suite works on one computer with Firefox 5.0 but when I downloaded Firefox for this computer I got vrsion 5.0.1 and it indicates Norton Security Suite is not compatable. Is there a way I can revert back to Firefox 5.0?

Download Firefox 5.0.

http://releases.mozilla.org/pub/mozilla.org/firefox/releases/5.0/win32/en-US/


Uninstall Firefox 5.0.1 and install the version above (Firefox 5.0).

You do not need to take care that Firefox doesn't auto-update to Firefox 5.0.1. Firefox 5.0 on Windows and Linux will not update to Firefox 5.0.1, either manually or automatically. Firefox 5.0.1 was specially made to correct issues on Mac.

I don't know what will happen for Firefox 6.

Get in touch with Norton about this issue, they are incorrectly specifying the maxVersion in their Firefox add-on. They did that with Firefox 4.0, too - as soon as the 4.0.1 update was released by Mozilla, their extension was broken. They should be specifying "all 5 versions", not specifically 5.0 - that means "their stuff" only works in 5.0 and if Firefox releases a security update "their stuff" is broken and they have to update it.


You can get 5.0 from the Mozilla "Releases" server - http://releases.mozilla.org/pub/mozilla.org/firefox/releases/5.0/win32/en-US/ - no need to get it from a 3rd party.

@the-edmeister, They should be fixing it soon, Norton Internet Security 2012 will contain an updated toolbar (as always), so they might be fixing this issue too.
