Firefox supportforum

Hi, for the past week whenever I open Firefox (FF) it works normally for about two minutes, then slows, then causes my entire mac to slow and freeze. If I don't force quit FF quickly, my mac crashes. Once I force quit FF everything is fine. I've been using Chrome for the past week or so hoping FF would fix itself with an update but no go.

Anyone else having this issues?

I would like Firefox to access the Mac OS "Dictionary" for immediate definitions, the way it accesses its own dictionary for spelling, or as Mac's Safari, accesses the Mac dictionary. I see nothing listed in Firefox>Services, nor does the OS's Services Preferences show Firefox as an app to connect services to. I can always get the definition with a right-click on the highlighted word, but I'd like the definition to be a readily available as the spelling.

TIA,

I followed instruction several time to uninstall and reload fresh and Firefox will not run, except in safe mode. This issue has happened once before and I solved it by reloading it fresh but this time I cannot get it to run.
