Hello everyone, one month back, after coupe of years, trying switch to mozzila ecosystem and have big trouble with Firefox CPU and Memory. The Firefox process CPU 54.5% and 5.8 MEM and Web content process CPU 108% (!!!!) and 16% MEM

My Firefox run only with 5 tabs WITHOUT facebook etc. Trying disabled all addons (have no add themes), trying restart browser, restart system safe-mode, task manager dont show some extra energy impact, reduced HW acceleration, nothing happens.. When i work with GIMP, inkscape and many other apps in row i dont have mayor problems with RAM or CPU.

Please, what can be wrong ?

Stop heavy downloads and close heavy websites to reduce the load on the system. This is especially true for online gaming websites. or Delete the corrupt content-prefs.sqlite file One of the major causes for Firefox causing high system utilization is a corrupt content-prefs.sqlite file.

Type about:support on address bar and enter to open the Troubleshooting Information page. Under Application Basics, you would find an option names Profile Directory. Corresponding to it, there would be an icon named Open Directory. Please click on it to open the Profile Folder. Once the Profile Folder is open, exit Firefox. Now, in the Profile Folder, delete the content-prefs.sqlite file.

Open the Firefox folder again and start browsing. The file would get recreated.
