Firefox 11 too slow for uploads
Since Firefox 11 installed onto my PC, I get about 15 instances of Firefox running in Task Manager, and uploads onto a podcast website are impossibly slow so that I am timed out from podcast website. Short video upload onto FB takes an hour now via Firefox11. The "Performance" fix has no 1-8 option anymore, unchecking "Use recommended settings" does nothing. Any solutions to suggest?
