What to do when Firefox runs slowly and hangups. Running on two PCs -- Windows XP & Windows 8.
Firefox has been working great on both PCs until the last week or so. If it was just running poorly on the PC with Windows XP, I wouldn't be so concerned. But it's running just as poorly on a new laptop with Windows 8. It seems to hang up if I have more than 3 tabs open at once or if I click a link within a site, the new tab opening hangs up. Frustrating! Can anyone offer some advice?
