Norton Internet Security / Norton AntiVirus

[xfighter]

I was using the Norton Internet Security 2010 Beta and everything was working fine (including Norton Toolbar).  When my Beta license expired yesterday, I uninstalled the beta and installed a trial version of the released version of 2010.  (I am running Windows 7 RC).  Now, for some reason, the Norton Toolbar will not activate in Firefox.  When I look at add-ons, it says "this addon will be activated with firefox restarts"  but no matter how many times I restart Firefox, it says the same thing.  I even tried rebooting my computer in case there was a rogue process running somewhere that would not allow Firefox to restart completely.

Any Suggestions will be appreciated.

I haven’t seen this issue myself but it looks like a problem with Firefox caching extension information. Please try the following to see if that resolves the issue.

1.       Close all instance of Firefox

2.       Open File Manager / Explorer and go to the following directory %APPDATA%\Mozilla\Firefox\Profiles\<profile_id.default> ( where profile_id will be a unique ID which looks similar to this 03610tdf.default.)

3.       You will see 3 extension files listed under this directory. Make a backup of these 3 files:

a.       extensions.cache

b.      extensions.rdf

c.       extensions.ini

4.       Delete the above 3 files from the file system ( they will be auto generated by Firefox )

5.       Now launch Fireofox and everything should be working as expected.

Let me know if that resolved the issue.
Thanks

This didn't work for me.  I went ahead and uninstalled Firefox and reinstalled it and it is working fine now.
