to FredMcD you know... i look at your profile and found out that you copy-paste the same "recipe" for all problems. Are you ill? Maybe something gruesome has happened in your life? Or maybe it's so useless that "Top 10 Contributor" label is the best achievement it can be dedicated to?

Did you try Firefox Safe Mode?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

You can also check for problems caused by other (security) software.

Ok. I found something. The problem caused by bloating of this script http://maps.googleapis.com/maps/api/js/ViewportInfoService.GetViewportInfo Both sites use it. When i block it - problem is gone. Hey developers! Maybe it worth to have a look.

to FredMcD >> "Sensors detecting hostility. Closing Hailing Channels." How old are you, child?

Actually this was not the "full solution". Performance continues to degrade but with much slower pace. there is something wrong with FF js engine.

Are you zooming pages?
