This worked great for me. While it's true that a small Javascript loop can hit the CPU without using memory, that's not what what most webpage scripts are doing - they are making remote calls, updating and manipulating the DOM, getting invoked by plugins (like Flash), etc. All these things can result in increased memory usage (especially if the page is slowly leaking objects). I found the culprit tab, closed it, used the Minimize Memory button, and Firefox was running smooth. Thanks again!–May 9 '14 at 17:02. By using and, now replaced with and you go a long way into blocking Flash or tabs, preventing CPU waste instead of tracking it. This holds, but less, for memory too.
Youtube is prevented to start until you click on them, so you may launch them in several tabs and they wait for you to open the tabs. Tabs are uloaded from memory and idle until you reopen them and they are refreshed from the cache (if still available).Shutting down the Internet for a while also works during the time you don't need it;-)Firefox fragments virtual memory so much that it's using an excessive amount of real memory (there is too much unused virtual memory in real memory). One needs to periodically stop and restart Firefox with the same pages. That will defragment its memory and the whole system will run faster by reducing the swapping.On my Ubuntu system, real memory usage slowly climbs up to 98%.
Then it's time to stop Firefox and restart it: it will then use less than 1MB of real memory instead of 3MB.The same holds for Thunderbird. Did before, did it again, and real memory usage stays at 92% when clicking any. Regarding Flashblock and Nevercrash than I mentioned, they became incompatible with Firefox 34. A 'did you upgrade to the latest version?' Eternal problem.
The wave is now Flashstopper and UnloadTab. Rather compatible but UnloadTab now unsurprisingly unloads tabs, needs no explicit 'unloading of tabs' (fine) and 'reloading tabs' acts as a page refresh (less fine, but using cache). One can set 'Keep Address Loaded' when that reloading is breaking a page state you want to keep.–Jul 1 '15 at 15:34. The following to another question may help you.
The answer is written by the user 'accolade'.is an awesome extension that can point out extensions and client side JS gone bananas CPU-wise.

As of January 2012, the latest version of XUL Profiler is 1.0.4, released December 2008. It's only certified compatible with Firefox 2.0 - 3.6.
