Why does McAfee cause FireFox browsers to crash?

I have an HP Pavilion PC with a 64 bit Windows Vista system. Owing to the nature of my PC usage I MUST run with ALL firewalls down and ALL popups allowed.

In addition I MUST use Adobe addon like Flash and Reader, AIR and Shockwave as well as Action X. I MUST also use FireFox browsers for these activities.

What I want to know is this- why does McAfee keep allowing my FireFox browsers to crash- constantly? No matter how often I upgrade FF McAfee ALWAYS

screws it up and crashes! As you may already know FireFox is staffed by a bunch of lunatics w/o intelligence so do NOT suggest asking them! I have asked and

asked and asked again to no avail dammit! HP will not help me. FF won't or can't help me. McAfee constantly uninstalls/reinstalls itself and always fouls up

something every single day! I have tried System Restore on the average of 25 times an hour and NOTHING works!! Is there anyone out there who knows what the Hell

is wrong with this piece of crap? Wish I could afford a Windows 7 upgrade but I am unemployed and have to depend on surveys, web ad surfing, contests, etc. just to make a little money!

PLEASE HELP out a poor slob nobody cares about? Please? Thanks I hope and sayonara for now- K&K- Brookhaven PA- USA

Re: Why does McAfee cause FireFox browsers to crash?

First I've heard of this as I use both IE8 and Firefox regularly in both Vista Ultimate and Windows 7 Uktimate x64 and have had no crashes.   It has happened with beta versions of browsers but shouldn't be happening with regular versions.  The only connection McAfee would have with the actual Firefox browser itself would be through SiteAdvisor as it uses Internet Explorer for display and communication.   Have you tried disabling SiteAdvisor if you have it installed?

Having all firewalls down may be necessary but it's certainly unsafe.  I would try scanning for spyware using the free versions of these two tools.  Update them before running and let them remove anything they find and reboot when & if asked to.



You may also want to contact Technical Support Chat to see if they have heard of similar cases.  See the McAfee Support link at the top of this page

What information do you have in the FireFox crash log, that might help pin point the problem


Have you tried uninstalling firefox? you need to remove your profile as well which is stored in a different place


There was an issue with earlier version of Firefox crashing but that seems to have been fixed with version 3.5.6 is yours up to date?
