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.

I am running 10 or more tabs with tradevision.io showing real time stock charts running multiple 1-minute charts forcing my CPU/GPU to constantly render live data. Enabling Hardware Acceleration in your browser settings can help balance the load and keep things running cooler but it made no difference. Prices still freeze and I have to constantly refresh. The CPU is flat out and running hot - my laptop is a top of the range xps 16

Why does Mozilla 154.0 always stall after a couple of minutes? It is a hell of a mess. I couldn't place this question without resorting to an older version of Firefox :-[[

Did anybody test V 154.0 anytime, at all?

I unfortunately updated a Windows 10 computer to this version of Firefox.

As such, I cannot provide you with troubleshooting information, because the new browser 154.0 does not work. At. All.

I did all the usual stuff like restarting the computer, the users of Windows OS junk are used to anyway. The Task Manager shows not less than 16 Firefox-processes, with a truckload of memory usage, having opened just one browser tab. Waiting for 20 minutes for firefox to show me the grace of continuing its operation didn't help either.

Any ideas?

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

u have asked how to stop Firefox from keeping saying firefox id running but not responding. I have gotten some answers but i need to let you know this is what i have in my task manager you will se the photo there is also one at the top plus i have all these profiles the one in bllue now i saw where it said to place.sqlite and rename it old i also took out parent lock and it is still happening all the time so what can anyone k help me stop this

For at least a few months now, my browser will suddenly and randomly go fullscreen all by itself. I can't exit it, and then it goes back to normal after at most a minute. It hasn't happened in at least a week. But today, it froze like that, not responding. I quit firefox, waited a bit, then restarted it. It went fullscreen and froze again. I waited at least 10min and it then went back to normal and responded again. It only happens when using firefox. I've done virus scans, etc, and it still keeps happening. Please help. Thanks.

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?

Firefox version: 153.0.4 / Windows 11 25H2 26200.9168

Attached are images showing the performance settings and the active extensions in case any of them proves to be responsible for the problem.

Yesterday I noticed a horizontal screen tear when scrolling down through sites like X(Twitter), YouTube, GMail, Reddit etc. I immediately checked my performance options and they were deselected. I activated them again, but this did not solve the problem, I also tried to active some layers in about:config but those were already activated. Checked Nvidia settings too, vsync is on, Edge is not affected, Chrome is not affected, even installed Waterfox to see if only Firefox-based browsers are affected, but that one was OK too.

Last resort was to refresh the Firefox installation from the uninstall utility. After the refresh and all settings/extensions got auto-reinstalled, the screen tear got fixed. I left the PC running over night and when I accessed Firefox again this morning, the screen tear problem was back. However, now, the performance options are disabled, and if I try to enable them and restart Firefox, the options get disabled again.

Would really appreciate it if anyone could provide a solution that does not involve refreshing Firefox daily.

After updating to Firefox 138 on Windows 11, startup takes about 30 seconds. Safe Mode is faster. I tried refreshing and it did not help. Marked **bold test** and [a link](https://example.org) plus {{7*7}} literal check.

For the last four days every time I go to clear my history,"Program not responding" with a white a line at the top of the page with a message to close program or wait for response. I have tried restarting my computer with no change. If I close the program and restart I don't see a change. It seems to be intermittent. Please find out what is causing this glitch .

Thank you.

Hello, For about two or three days now, when I launch Firefox and try to open any website, it takes maybe one minute to load the page, then the navigation is OK on every website.

It only happens when I launch Firefox for the first time of my session. If I close it then relaunch it, it's still very swift.

I tried clear cache and remove cookies, just lost my logins lol but didn't work. I also tried with no extensions, nothing changed. Lastly I tried to set "network.captive-portal-service.enabled" to "false" in "about:config" but it didn't change anything neither.

So before I try anything else that could erase something on my profile, I'd rather ask here for some help :)

PS: running FF 153.0.4 on Debian Trixie with Mozilla repos. Only have two extensions: µblockOrigin and NoScript.

Thank you in advance!
