Solved Going Crazy

[IrvingSF]

I have not made any changes to this machine and use McAfee Security Center which detects no virus problems so I do not understand what is going on. This week I am suddenly receiving the following error message when trying to open some e-mail: [Yellow triangle with exclamation point in middle) followed by: Exc in ev handl: TypeError: brw is undefined. I sometimes receive the same message when clicking on one of my bookmarks. Also, Firefox is driving me crazy with little changes and now my toolbars from Yahoo and Google are all messed up.

I get the following link when googling for Exc in ev handl: TypeError: brw is undefined. https://support.mozilla.com/en-US/questions/864210

I got the same message after a recent update for Firefox 6.0. Such a pain in the @#%. Did everything they suggested from other forums and from the above link from bigcitycat. Still have the problem. I disabled all extensions and add-ons and still there. Firefox is getting worst. Such a memory hog also. Better off staying with Chrome. Anyone else have any suggestions?
