Every now and then while browsing, my Firefox CPU usage shoots up to the max possible (that's 50% for my dual processor laptop). It remains at max usage even when I close all the tabs. In fact, the Firefox process keeps running even after I close Firefox. I have to go to the Task Manager and close it manually.
I observe this both on my home (64 bit Windows 7) and my work (64bit Windows Vista) computers. Here are the add-ons I have installed on both:
- Adblock Plus
- Delicious Bookmarks
Does anyone have a solution?
