Hi Da7mi, sorry you are having problems. Thanks for starting your own thread about this problem. The original long related thread being: * ''Firefox 23 uses 1.2 GB of RAM with 4 tabs open!'' [/questions/967643] (Automatically archived and closed as an old dormant thread) It is very hard to generalise about what is normal memory use for Firefox, but using 1.4GB for 2 open tabs seems extremely unusual, and highly excessive. As you have probably realised easy to find and fix memory issues have probably been dealt with. What remains are the many real but hard to properly identify issues where often *No one has yet demonstrated Steps To Reproduce that are good enough for a bug to be filed. *Or the issue is due to third party software or site use. The long thread will have suggestions and links to useful articles. With longer explanations and details about testing. May I ask that you try to help with some troubleshooting here. Please post back if I need to expand on this. # Let's as a test comparison try using Firefox in a simpler configuration with less complicating factors. Please run as follows #* Use a new additional Firefox profile as a test <br /> [[Use the Profile Manager to create and remove Firefox profiles#w_creating-a-profile]]_creating-a-profile <br />Use default suggested locations and do not delete any new profiles. #* Run in Firefox's safe mode <br /> [[Troubleshoot Firefox issues using Safe Mode]] #* Disable all plugins (Safemode does not do that) # Obtain memory results from ''about:memory'' Firefox's own reporter. #* That does have a facility to save the interactive reports as gzipped files, but we have no direct support on the forum for such files. If they need posting it has to be on some separate third party site. <br />( I did [/forums/contributors/709551 ask] for that as a forum enhancement without success ) #* Use ''about:memory'' by navigating to it by keying into the location bar and hitting the return key, or mouse click the green arrowhead. #* About:memory is interative, note it provides information on mousover, and some branches will expand.

Hi Da7mi, sorry you are having problems. oops duplicated in error, deleting the rest

Have you tried Firefox safe mode? If it uses less memory in safe mode you may need to disable addons and or hardware acceleration. More info is in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] and [[Troubleshoot Firefox issues using Safe Mode]] articles.
