Firefox Community Forum

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.

Hi there,

I’m using the Firefox Multi-Account Containers extension and would like to remove a site that’s been set to "Always open in [X] container." However, I don’t see a “Manage Site List” option anywhere in the container settings as seen here: https://support.mozilla.org/en-US/kb/containers

Here’s what I’ve tried so far:

   I’ve clicked the Containers icon and selected the gear ⚙ to edit a container.

   I enabled privacy.userContext.siteAssignments.enabled in about:config and set it to true.

   I restarted Firefox (with session restore on), but still no option appears to view or manage assigned sites.

I’m on Firefox Desktop (Mac), and I’ve confirmed that I’m using the official Multi-Account Containers extension.

Is this a bug, a UI change, or something I’m missing? I’d really prefer not to manually edit the containers.json file if there’s a built-in way to manage these assignments.

Thanks so much for any guidance!

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

For years I have been able to watch a foreign TV website, despite having only a DSL connection (I allow only the scripts essential to make it work). Since I did the last update, to 137.0, I cannot watch either the live stream ("General source error") or old programs ("There is something wrong with your internet connection"). This is absolutely consistent; I've lost count of the times I've tried.

I never had problems like this before. At worst, if Windows was running a background process I might have to stop it to keep from having pauses in the program. All I can think of is that you did something in the new version of Firefox that has made video impossible on DSL.

The proxy settings just don't apply. I set the settings on the system, all programs work via proxy except Firefox (set to use system proxy settings). If I set the proxy manually in Firefox, the connection still doesn't go through the proxy.

I found that only the very first connection after starting Firefox goes through the proxy, absolutely all subsequent connections do not go through the proxy.

I have removed Firefox and installed fresh the latest version 137.0.1 to address the issue of not being able to start a new tab or a new window. I am writing this from the initial window that opens when Firefox is launched. If I try to open a new tab it will hang with the blue circle displaying. If I click anywhere on the window if will grey out the background and display the error message :

Firefox is not responding

if you close the program, you might lose information

-> Close the program -> Wait for the program to respond

Tried waiting and it never comes back. Only option is to close the program. After that there is a message that is reporting the issue to Microsoft.

OK, this is getting to the point where I no longer want to use Firefox. I have had trouble in the past where if I went on Edge for some reason and logged in to my email, when I returned to Firefox I was logged out of all my Yahoo powered email accounts. When trying to log on I would receive the attached message and it would take hours, and sometimes days to be able to log on. Even when I was logged on to my main mail account, I would not be able to log on to the other two accounts. The last time this happened is when I realized it coincided with me logging into my email on Edge, so I have not logged into my email using Edge since then. Unfortunately that was just a coincidence, because it happened today and I hadn't been on Edge since I posted my previous question in February.

I am always logged into all three accounts, but since this happened two months ago, I only logged into my main account and one other on Firefox, but I have only accessed the main account since logging in to both of them. I only accessed the other two accounts on my phone, which was fine, but I sent my phone to get the fingerprint sensor repaired so I'm using my wife's old iphone now. Don't get me started on how this phone sucks, but I needed to access one of the other accounts today and I don't have either of them set up on the Yahoo app, and I didn't want to take the time to set up the one now when my phone should be back in my hands in a couple of days. I came in the house and fired up my computer again opened my email and switched to the account I needed and surprise! I was logged in. I did what I needed to do and tried to switch back to my main email when surprise again! I received that same dreaded message.

I have been trying to log in to my account on and off for about five hours now, and I'm about to toss my notebook across the room. That would leave me without a PC though, so I am forced to use Edge, but for how long? I have posted on Mozilla support many times in the past for different things, but I have never actually had anyone from Mozilla provide an answer to any of my issues. Is that because this is only a community forum? Does anyone that works for Mozilla or Firefox actually access this forum and see these questions? If it's only a community forum, where do I get post my issue to be able to receive answers from the people that make Firefox work? My last post in February had 17 views, seven others that have the same issue, (so I'm not the only one), and no replies other than my posts adding content because you can't edit your original post. Evidently the people that have an answer to my problems haven't seen it.

Maybe I selected the wrong topic? I don't remember what topic I selected two months ago, but I selected passwords and sign in today, so hopefully it's not the same topic and maybe I'll receive some input this time.

Thanks in advance.

Hello there！ I recently updated Firefox to 137.0.1. But the update doesn't automatically display the status bar when you hover over the bottom of the page. I had to resize Firefox to make it full screen to display the status bar properly. This makes it difficult for me to use Firefox. I'm pretty sure this is due to a version update. This problem occurred after I updated the Firefox browser, during which time my Windows system was not updated. Is there any solution? Or how can I download a previous version of the browser?

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

I am evaluating a password manager application and exported my FF passwords and imported them into the app. For testing I removed all of the passwords from FF. I want to password protect the csv file rather than delete it in case I need to import the passwords back into FF. When I go to File/Info, the "Protect Workbook" option is greyed out. When I go to the "Review" tab, the option to "Protect Workbook" is available, not the "Unprotect" option, so the workbook is not protected. If I click on the "Share" folder on the right side of the ribbon, there is no "More" option. In Windows Explorer the file is on my desktop, not OneDrive - Personal. I right clicked on the file, selected "Give access to" and took the option to remove access. The File/Info option is still greyed out. How can I password protect this file or how can I export it in a format that can be imported later?

I have accounts that will not work because they cannot access my location, My computer says all access is allowed, so is there something in Firefox that blocks my location?

when i go to a site using firefox i get this message:

Secure Connection Failed

I cannot figure out how to add my favorite things to the toolbar. The toolbar doesn't even show up at the top of my page. I just get a string of random bookmark names under the address bar with the Other bookmarks folder at the end. I can't even get rid of "Finish Setup" which is the last one shown. How do I do find where the toolbar is hidden and get it to show? Once I do find it, how can I add my favorite items to the toolbar? I even had ask a question online to find out how to restore my most recent bookmark which was backed up in the documents folder on my computer. Any suggestions would be very helpful. I don't like the way Mozilla Firefox looks now. It isn't as easy to use. I have included what the top of page looks like now. I am sorry I didn't think to keep one of how it used to be.

'Running ver 137 and now cannot print to my system default printer. Tried the Troubleshoot fix and same result - defaults to PDF. Is there any entry in about:config to ensure system printer is selected. I have checked all system settings and brother printer is the default.

suddenly my work account at https://outlook.live.com is a completely white screen.

access to other instances of this account (Onedrive, filesharing etc) are fine. Email account works on phone, so no problem with log-in

I have re-started the browser
