Firefox Community Forum

So normally firefox uses a reasonable amount of ram but sometimes the amount of ram usage almost doubles, then if I try to change tabs the program freezes. I then have to wait for firefox to stop using the excess of ram and return back to normal levels.

I believe this mainly happens when I have youtube or reddit open but I have no idea how to fix this.

I have already tried reinstalling firefox and deleting/changing extensions. The current extension i have on is adguard adblocker and no others.

I'm experiencing continuous screen blackouts or glitches. These are unaffected by the site I'm on and only occur for Firefox browser. When I switch a tab or click a button the browser blacks out and becomes unresponsive then comes back on after a few seconds. This happens repeatedly. Clearing the cache, running a repair, and uninstalling / reinstalling the app have had no affect on it.

Whilst on various websites, reading articles or even on Gmail, Firefox takes me off them and takes me to Recent Browsing and I have to click on the website from there - this happens frequently.

Hi folks My configuration: MacOS Tahoe FF 15.4.0 When I relaunched FF after restarting the Mac, in the Windows menu all the pages from the previous session were listed but none appeared when I tried selecting them. They must be hidden somewhere. I tried several work-arounds. The one that gives a result is by selecting in the View menu the Enter Full Screen item, then try to go back to a normal view which is a pain in the neck. Is there a clean method to make all those windows come back to their normal position and if possible preventing FF from doing this in the first place? TIA Nick

If my computer idles for a long period of time, Firefox doesn't recover at all. If I leave a website open, Firefox won't let me go back into it. I need to close Firefox, wait 10 seconds and open it again to open any website.

Whenever I click any link that will play a video in a video playing website such as YouTube, Instagram or TikTok, it will cause the entire tab to glitch out and freeze in on the page it was on before I clicked the link.. The entire tab completely freezes and never unfreezes itself, with the cursor having whatever appearance it had when the page froze, and being unable to click anything. The only thing it can do is type a new URL into the search bar, but the search button/enter bar is also ineffective, so I'm stuck on a frozen webpage unless I close the tab or change to another one. I've tried troubleshooting, fiddling with the autoplay setting and turning off extensions, none of which worked. Any ideas?
