New download of Firefox v. 3.6 for Vista seems very slow. Can anyone think of why this would happen?

April 5th, 2011: First, I didn't install Firefox 4 because it doesn't support Norton 360 and the related toolbar which is crucial to me. So I installed 3.6 which I have used before which was corrupted by a Trojan virus I was infected with. I had to uninstall everything and in the interim I used IE8. I re-installed Firefox 3.6 yesterday and the only add-on I installed was the Yahoo! Toolbar for Firefox.

Added on April 6th, 2011: Also, I forgot to add that often times I am waiting while the top of the screen says "Mozilla Firefox" - (Not Responding) which is what I went through with IE8. I'm getting VERY frustrated.

Any help anyone can give would be greatly appreciated.

Thank you in advance for your prompt attention to this question as I am VERY behind in my work due to all of this "mess". :(

Norton has released a patch to address incompatibility issues with Firefox 4. See Norton Compatibility patch Firefox 4.0

If you would like to update to Firefox 4.0, please do that before you install the Norton patch. Update via Help | Check For Updates preferably.

If the problem persists, try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.

The Browserplus plugin you have installed will almost certainly cause Firefox to hang occasionally and it would be wise to disable it via Tools | Add-ons | Plugins.

You also need to update Flash to v10.2.159.1 which also patches a recently discovered Zero Day exploit. See Adobe releases security update for Flash Player You can update Flash via http://get.adobe.com/flashplayer/

Similarly, your Shockwave For Director plugin is also out of date which may cause Firefox to hang if the video requires a newer version. Update that via http://get.adobe.com/shockwave/

Last but not least, consider disabling the Yahoo ActiveX plugin via Tools | Add-ons | Plugins. ActiveX is a Microsoft technology which is frequently targeted by hackers. By installing it in Firefox, you're comprising the browser's security and potentially exposing your system to attack. Firefox can open any Yahoo page without requiring ActiveX to be installed.
