My typical usage has not changed from FF10<br /> which did not have this same magnitude problem.<br /> <br /> Open over a day about 30 tabs in 2 windows.<br /> (Response is fast when started ).<br /> Continue to use for several days ( machine and FF stay up).<br /> Response gradually, almost unnoticeably slows.<br /> And then it slows quicker.. <br /> you end up with 10-15 second waits for any click<br /> or keypress.<br /> <br /> Closing 10 windows does not help.<br /> There is no swap activity happening<br /> via LED on front panel during use.<br /> <br /> Box is 2.8 Ghz with 1 gig RAM.<br /> java is not enabled, javascript is.<br /> Download helper, FireFTP are installed, not used,<br /> and adobe flash is installed.<br /> <br /> Top:<br /> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND <br /> 25116 waltech 20 0 895m 314m 33m R 100.5 31.8 1665:20 firefox <br /> 30133 waltech 20 0 258m 72m 19m S 3.6 7.3 113:07.07 plugin-containe <br /> 24650 root 20 0 53816 19m 10m S 2.0 1.9 426:43.24 Xorg <br /> 30024 root 20 0 100m 26m 20m S 0.7 2.6 3:37.87 kppp <br /> 27 root 20 0 0 0 0 S 0.3 0.0 3:09.64 ata/0 <br /> 5484 waltech 20 0 62516 11m 8980 S 0.3 1.1 0:00.50 gnome-terminal <br /> <br /> <br /> FF is closed and restarted and 3 tabs opened:<br /> <br /> top:<br /> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND <br /> 5484 waltech 20 0 62676 11m 9048 S 2.0 1.1 0:03.18 gnome-terminal <br /> 24650 root 20 0 49932 19m 10m S 2.0 2.0 428:02.59 Xorg <br /> 5647 waltech 20 0 2700 1124 852 R 0.7 0.1 0:00.13 top <br /> 24897 waltech 20 0 57024 9480 7784 S 0.7 0.9 12:22.17 parcellite <br /> 30024 root 20 0 100m 26m 20m S 0.7 2.6 3:47.07 kppp <br /> 5534 waltech 20 0 603m 168m 33m S 0.3 17.1 1:28.63 firefox
