    Firefox - CPU usage at full power

    I know the system is less than ideal, however this worked well in the past and it still works nicely on windows PC. i would get high usage on both cores there only in the first 10 or20 minutes as the antimalware runs. but after that it is quite calm.

    here i get 100% usage with one or two tabs open. the Radeon drivers seem to be working ok (as far as HW acceleration is concerned. tried to play a few old games and they work OK. of course more work on the win7 starter which is on the other side of the hard disk.

    occasionally i noticed the fans would get loud and sometimes the desktop would freeze. so i guess i should monitor the temperature as well. but in my opinion there is no good reason to get the CPU working so hard just to display a page. does this have something to do with flash? 14.04 had fglrx drivers and i haven't noticed high battery use there or high CPU usage,

    attached is the CPU fluctuation as i was reading The Guardian website on one tab. here is the PC data:

    btw Kubuntu forums one tab open keeps CPU at 6-10% which is kind of expected value. even 20 would be ok but 100%?!?!
