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.

Firefox under Linux Mint 22.3 Cinnamon, will not let me input text. How can I get past this?

I am having to type into a text file, copy and paste to get information into a text box in Firefox.

My summary says it all, really. There's not much more that I can add, except that I have used Firefox for many years and have never had this problem before. The index page itself is fine when I view it in Firefox. And if I right-click the page and view its source code, everything is there. Furthermore, I have no difficulty in editing the page in other browsers. (Since this problem arose, I have been using the Norton browser. But I have also been able to scroll down to the end of the source code in Google Chrome.)

A week ago, Firefox started freezing and acting all glitchy. Troubleshooting said to uninstall and reinstall, which I did. That's when the real trouble began. It lost all my data, pretty much signed me on as a brand-new user. Luckily, I was able to recover my data from my phone app, but it still did not work correctly. Nothing in the support pages was helpful, so I finally had ChatGPT assist. We got it restored using my recovery key and I though that everything was fixed. Then two days ago I got the 'not responding' thing happening every time I tried to reopen it, along with a generic Firefox web page opening randomly. I reopened it several times in troubleshooting mode, again, no help. So. uninstall, reinstall, uninstall, reinstall... you get the picture. I finally thought I had gotten it properly restored at 5:30 this morning with all my previous tabs showing up. But as soon as I tried to use it, the same old 'not responding' message. I always get the pop-up asking me if I want to close it or wait for it to respond, which it will eventually do, until I try to click on a tab. What the hell am I missing here? I've had Firefox for, oh, I don't know, 20 years or so. Never had problems.

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?

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.

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.

Firefox 153.0.4 on MacOSX 26.5.2 on a 2021 M1 Macbook Pro.

2 finger scroll barely works, it's very laggy. Sometimes 3-5 seconds after the physical movement.

Change: Settings -> Displays -> Promotion (set back to 60hz) fixes it.

So far no messing with about:config settings has fixed things. Turning on / off smooth scrolling makes no difference. Turning on / off hardware acceleration doesn't change anything,

Seems like a recent bug.
