When I open Firefox, the profile I open with will open perfectly normally to version 153.0.4 and says it is up to date. However, if I open a different profile, that one will say it "Firefox is being updated by another instance". I can quit the app and change which profile I open first, and that profile will be 'up to date', and the other one will be 'being updated'.

I already went through quitting all pending tasks in task manager and restarting my device, as well as deleting and redownloading the app. This is really slowing down my processing speed while I work! Please help. I really don't want to lose my profiles.

You installed without my permission the Microsoft web app. That is spyware that has cost you this user. I will uninstall Firefox, tell everyone I know what you 'security-minded' liars are really doing to us. I belong to a gaming club with hundreds of members and by tonight they will all know not to trust Firefox. You really have some nerve teaming up with that nasty organization. Before this day is out all my contacts on all my social media sites will know what you are doing. I have a $3,000 rig that you jeopardized.

I have been using your browsers for years. No longer. Any time I can bad mouth you I will. You can take that to the bank.

I just recently installed the VPN on Firefox. It hadn't shown up because of my privacy settings. It works fine except for the United States connection. When I choose the other countries, it works fine, but when I choose United States, it still shows Japan (where I live). It still shows Japan, but it does have an effect. It changes it to Tokyo, where I don't live. So, the vpn is having some effect, but it is just not connecting to the United States. Why is that?

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.

firefox on windows 11, keeps blocking my camera and Microphone despite express permissions to allow, i look in permissions and the site is clearly marked to allow camera, but when i goto sitye, no camera or mic is allowed until i delete the permission that is supposed to allow it.

I have counselling at https://survivorswestyorkshire.whereby.com/chrissy

I allow my camera and mic.

I return to the site and it tells me camera and microphone blocked.

I goto0 settings>Permissions>Camera

It clearly states that the website is allowed to use the devices, but when on the website the devbices are blocked. Whats messed up is, if i delete your settings>Permissions>Camera, it allows me to use my camera and mic, until i refresh the webpage and its blocked again.

This makes zero sense and is every reason for me not to use Mozille Firefox as a browser at all.

Trying to get stuff done. It's hard when you start a task in one tab ,switch to another tab to start another task, and when I switch back to the first tab, it hadn't completed the task, it actually paused when I left it. What's the point of multiple tabs, when only one is working at a time? I expect it to continue with the task, while I go elsewhere to complete a different task.

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.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

I have webpage (Home Assistant instance) on my local network on which I would like to use microphone (for Assistant functionality). Page is completely local, i.e. not visible from Internet. My issue is I can't force Firefox to allow microphone access on this page. I've tried messing with media.devices.insecure.enabled config, but it didn't help. Is there any way to add such page to some whitelist to allow microphone access? From what I gathered Chromium-based browser provides "--unsafely-treat-insecure-origin-as-secure=..." option but I didn't find anything similar for Firefox. I know I could expose my server to outside network and get SSL certificate (from Lets Encrypt) to make it work, but exposing server to Internet just to get local microphone access somehow doesn't feel like a more secure solution. I could probably also issue self-singed certificate but dealing with that also seems at least annoying.
