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!
