Firefox Community Forum

I am not able to use Mozilla Firefox on my computer. It's the only browser I have been using. When I tried logging in today, I got a pop up the said: 147.0.1 is not compatible with min version 147.0, max version 147.0. Try to reinstall. I reinstalled but no luck. Please help. I need my bookmarks.

I've been using Firefox since forever but over the last couple of months, the auto translate subtitles (to English) hasn't been working when watching Youtube videos. There's a thread on the Youtube support site with nearly 40,000 posts of people with the same issue and tonight I was trying to watch a video where the hosts talk in Italian, so I use auto translate to English subtitles but no subtitles appear. It will show Italian language subtitles.

I've gone back through this Youtube channel's history trying videos I've previously watched from months/years ago when auto translate used to work but even they're not working now.

I decided to try the video in Edge browser and to my surprise the auto translate to English worked there. They also work in Chrome.

So what could be causing this issue on Firefox, which started about August time?

This is quite bizarre as I assumed all the processing/translation was done by Google/Youtube so in what way can Firefox be part of this issue?

To be clear, subtitles in the (foreign) language the people are speaking, works. Subtitles translated from that language to English (or other languages) has stopped working. Subtitles translated from that language to English IS working on Edge and Chrome browser.

A few days ago my saved passwords all disappeared. I have been logging in manually and when I do Firefox asks if I want to save the password and I click yes. The password then shows up in the saved Passwords. But... in a day or so it disappears again. What's going on? I have not changed any settings.

I despise ai in every use and way with a passion. Now, it gets spammed everywhere on this browser, with no apparent way to disable and/or remove that filth. I don't want to see it, ever! Why is it even on by default??? I don't want "chatbots", "Ai assistants" or any of that shit at all.

1/19/26 I have used Firefox for years and now it looks like Microsoft Bing has taken over and I cannot get Firefox back. It installs to a certain point and stops. Can you help me? email: [edited email from community support forum]

No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

Since upgrading to 147 last night, ChatGPT does not work and there are issues with other websites (Amazon side bar). Numerous people reported it on reddit. Any suggestions for a fix?

When right-clicking on the Firefox icon in the Windows task bar one has the option to "pin" items by hovering over an entry in the "frequent" list and clicking on the little pin needle icon (with the hover text "Pin to this list").

How can I pin items that are not in the frequent list? I have tried for weeks to make an important page a frequent one by making sure to visit it daily but it never makes it to the list.

I rebooted my laptop to find that Firefox removed all of my data. I looked up for ways to fix this and then arrived at the conclusion that I could create a profile and set the folder to one of the profiles that weren't listed on Firefox. It seemed to save my history correctly and my saved downloads, but they all said that they were moved or missing. I checked the passwords and instead of the long list of passwords that I normally have, there were only a couple, and the passwords were also sometimes outdated. I cannot recover some of these passwords. I've tried checking the passwords in the other profiles that were listed in the profiles and nothing shows up. None of the cookies were saved either

Hi.

I had to install a new OS disk. So, I created an account, and made a synchronization. Then, I made a security backup. When I installed the SO and Firefox, I logged in to sync. As soon as I logged, it automatically started to sync the random tiles it had after install. So, I had to use the places.sqlite and favicon.sqlite files. It got me half the tiles, and even those were misplaced. So, I had to go for the security html, and I finally got everything I wanted. But, now it says the account is not associated. If I login to associate it, when I shut down the PC, it returns to those half tiles, and out of order.

How can I get this right?

I think you should consider launching your new CEO out of a canon, metaphorically speaking.

If people wanted AI slop shoved in their faces, they'd go use a crappy chromium browser, which is where that stuff lives. We use Firefox because we don't want any of that crap in our browsing experience. "As long as you can trust it" - who does this guy think he is? You can't 'trust' AI, it's not a person, it's a tool (implement) used by tools (inept idiot).

You also can't trust corporations that pivot to AI, either. If you want to double down on anything relating to AI, then double down on keeping Firefox AI slop free, and ensuring that you are the browser for those that need refuge from this crap.

I remember when Firefox really was a nonprofit that survived on donations from its users, rather than just another corporate shill for companies and LLMs.

Be better. You disappoint me.
