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

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.

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 .

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.

Tabs randomly freeze/unresponsive after resuming from sleep (Windows 11)

Hi everyone,

Since updating to Firefox 129 on Windows 11, some tabs become unresponsive after my laptop wakes from sleep — no crash, no "Not Responding" warning, just frozen. about:processes shows the tab still running with ~0% CPU, so it's not hung, just not repainting.

Tried: disabling hardware acceleration (helps a bit), fresh profile (still happens), Troubleshoot Mode (less frequent but not gone).

Anyone else seeing this? Known WebRender/compositor bug tied to sleep/resume, or a Windows 11 power management conflict?

Thanks!

Hi! We have automated tests that run in Firefox across a large number of instances. There are about a hundred nodes where the browser is launched. For security reasons, there is no Internet access. When the browser closes, requests are sent to 146.75.117.91. Since there is no Internet connection, the request fails to complete, and the process terminates due to a timeout. Because the browser is controlled by geckodriver, the `driver.close()` call fails with an error. I’ve tried numerous browser startup options, but none solve the problem; the process still crashes. The only thing that works is blocking the IP address at the firewall level or in the `hosts` file. However, I’m not happy with this solution because it would need to be applied to a hundred nodes, which would create scalability issues down the line. Are there perhaps any options I missed? I also found these addresses in `omni.ja`. Could it be that they are hardcoded and cannot be changed via options?
