On two different Windows machines, current Firefox (153.0.1), the alt-d shortcut stops working: it does nothing until I restart Firefox. Then it works again for a while. I've tried about:keyboard and it's not reset there. I tried all combinations: Clear, Reset, setting it to alt-d explicitly. None of those worked. But when I set it to alt-a, that worked--but then resetting back to alt-d again didn't work. That shortcut is muscle memory at this point, so it's quite distressing. Not sure what diagnostics might be available to help here, happy to try anything.

Full disclosure: Both machines are Windows 10 but since that's stable, I find it hard to believe that's related.

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.

From time to time I stumble upon videos that do not have Picture in Picture button and when I switch tab, they do not open PiP automatically. Example: https://youtu.be/BrNglFVnMMw Majority of videos works fine. Do you have any idea what could cause it? Is it some youtube DRM?

Some very bold claims that I don't see backed up by anything having to do with reality.

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?

Under Settings>Privacy/Security>Browsing Data there is no longer the option to Manage Cookies, despite the help section saying that is where to find it. There is no other place in all of Settings to find the list of cookies. There is only the ability to delete all cookies in History, which I have no desire to do. I edit the cookie list weekly, and it is only now, mid August 2026, under Firefox 153 on Win 10 that I no longer have access to them. How do I get it back?

Hi everyone,

After a recent series of updates to both my mouse and Firefox, my mouse no longer scrolls within Firefox. The mouse is Logi wireless mouse. Firefox is the latest version. The mouse scrolls fine in other apps, like WhatsApp, Outlook, Word etc. but not in Firefox.

When I try to scroll in Firefox, it stutters, jumps and will continue to jump even when I stop scrolling on the mouse.

I have spoken to Logi and there is no issue with the mouse itself.

I have tried Troubleshoot and Private mode, but still the same issue, so its not an add-on or extension problem.

Is anyone else having this issue over the last couple of days, or have any ideas on how to get back to smooth scrolling?

Thank you, Graham

After copying profile that's already synced to my old account, I'm unable to set sync that copied profile to new mozilla account. According to support page, it should sync just fine by using different mozilla account. From what I noticed, this new copy profiles feature doesn't make a new profile in about:profiles, could this be an issue?
