That's a point I guess, there might be something in my system that's causing the problem. I have very few Firefox extensions though.
Here's what top shows me almost as soon as I search for something on eBay:-
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 32209 chris 20 0 2419636 623696 153632 R 115.6 7.8 1:13.40 Web Content 11127 chris 20 0 2631504 363904 109840 S 33.2 4.5 5:41.42 firefox
After that, it continues similarly until I leave eBay, then it settles back to normality. Re-open an eBay window and it goes back up to using a large proportion of my CPU (core I5, fairly fast).
... and I just tried firefox in safe mode, as soon as I hit eBay:-
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1539 chris 20 0 2218152 403968 152128 R 114.3 5.0 0:12.06 Web Content 1487 chris 20 0 2226416 318996 142412 S 37.9 4.0 0:08.75 firefox
If I leave eBay and go to (for example) Wikipedia:-
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1539 chris 20 0 2304840 243044 126516 S 8.0 3.0 1:10.36 Web Content
it's actually quite rare that firefox/Web Content gets up near the top of the 'top' display when it's working normally, like every other process it moves around. It's just eBay!
After looking at this I'm amazed at how directly it's linked to eBay, I sort of thought it was eBay before but now I can just switch the heavy CPU usage on and off by opening and closing a single eBay tab. If I spend a lot of time searching eBay I think things get so clogged that the only way out is to stop and restart firefox. It's only when I've tried opening a single tab and moving to and from eBay that the connection is so obvious. When you leave the eBay page it takes several seconds for the CPU usage to drop back to low/normal levels.
I guess I could simply use a different browser for eBay but that's not ideal.
