Firefox (on windows) constantly consuming 10% CPU - is there an add-in to find the rogue tab? [duplicate]
Solution 1:
I often have many Firefox windows open, each with many tabs.
It's normal behavior to have some CPU (and a lot of memory) usage when having a lot of tabs...
If you suspect too much, check for dynamic content on the web page, whether it's Javascript, Java or Flash.
Some examples:
- Advertisements
- Animations
- Auto-refreshing behavior
- Chat message queries
- Multimedia
- Tickers
