Firefox becomes very slow with Yahoo All-New Mail

Problems with the Yahoo! All-New Mail version: Everything was working fine, but since the last two Firefox updates I began noticing that Yahoo was consuming a lot of CPU (it varies from 35% to 40% and is on the top list of programs CPU consumption) and the experience of navigation becomes not so pleasant - slowness. If I quit Firefox and reopen it, becomes faster, but after about 30 min slowness / CPU high consumption start again. Then I had to come back to Yahoo Mail Classic version and everything works fine and less CPU consumed. Is it only me experiencing this? Is it a Yahoo Mail issue? Is there a solution? (Macbook Pro early 2011/ Mac OS X 10.7.4 / Firefox 12.0) Thanks!

被選擇的解決方法

Try to start Firefox in Safe mode. This mode disables all extensions, user customizations, hardware acceleration, etc. temporarily for diagnostic and troubleshooting. If Firefox works fine in Safe Mode, then this is likely an add-on issue. Restart Firefox in normal mode, then type "About:addons" (without the quotes) in the address bar. Disable your extensions one by one, restarting Firefox between each one, until you find the trouble maker.
