The other day I attempted to use a script in the Greasemonkey extension, which would not work for me. I deleted the extension in the end, but in the process of trying to get it to work, I disabled all other extensions for a time to test what the problem might be.

Ever since then my profile seems to be corrupted in some way. I have refreshed Firefox, as well as made a new profile to test where the error must be. As soon as multi-account containers is reinstalled, the problem returns. This includes the fact that yesterday, for unrelated reasons, I decided to install Linux Mint for my OS and stop using Windows - as soon as I signed in my Firefox account and the profile synced in the new OS, the error returned. (The attempt at refreshing Firefox was done after installing Mint; the test profile was done on Windows.)

This is the behavior I'm seeing:

- I cannot drag a tab that's logged into a different container into a tab group with tabs that are not signed into any container. This includes tabs logged in on the Facebook container. - In fact, I cannot drag any tab that is logged into a container anywhere - they insist on being all the way to the right in the list of tabs. - If a tab logged into a container is all the way to the right in any given window, the button to open a new tab will automatically open the tab in that container instead of opening in no container, which is my preference.

I use the multi-account container extension extensively and would like to see this fixed. If anyone has any idea of what could be happening here I'd appreciate the help!

Hello!

I'm a daily user of firefox and for years I've used the pinned tabs to save my current videos, websites, whatever so I can watch later. Never had any major problems, if I accidentaly closed a firefox window with the pinned tabs while having another firefox window opened, I would just "Restore previously closed window" and get all my stuff back. But now, from yesterday night 2025-08-31 to this morning 2025-09-01, I opened firefox on my PC and my tabs were not there, there was also no option to restore the previous session or window, I simply lost all the stuff I had stored.

I perused the files in the dir `sessionstore-backups` of my profile and they are all from this day, not from the previous day.

Is there any way you guys store those backups from previous sessions when syncing my data to your servers? Can I recover these at all?

Cheers

Every since I updated my MacBook Pro M1 Max chip to Firefox 142.0.1 (aarch64), Firefox locks up & has to be "Force Quit" & restarted almost every day. Please update the app ASAP so I don't have to convert to Google Chrome. Thank you!

So the other day I spent hours deleteting old bookmarks (and bookmarks that have for some reason duplicated) from firefox browser, alongside tagging them and other housekeeping things but when I went back into the manage bookmark page all the things I did yesterday had reset so all the bookmarks I had deleted came back all the tags (but one) I made gone. So how do I stop bookmarks resetting to what they were?

After 11 year I suddenly can't access my Wordpress blog on Firefox. I have to use Chrome to access it - with no problems. I have been on Ubuntu Elementary for years years and have never had difficulty accessing my blog. I have uninstalled and re-installed Firefox twice, I have emptied my entire cache and cookies. I also tried to empty my DNS on Ubuntu Elementary but my version doesn't have DNS. The problem started 24 hours ago.

HI, After upgrade to Seqouia 15.6.1 an extension for developing Oracle APEX applications breaks Firefox. It is the only extension I have installed. Console information is not really that helpful. Maybe you can make some head and tails about it.

Whhhhyyyyyy am I suddenly unable to access certain parts of the Delta.com website?? I had no problem with the website re my outbound flight and now I can't access any info on my return flight on their "flight details" page. They had to send me a screenshot of what they had on their screen because I cannot get it on my own screen. I am worried as I get closer to my departure date that I still will not be able to access my flight info and will not be able to check-in! They told me to change browsers! Help! 😳

Hi. I have been using Firefox with DuckDuck Go extension for maybe 6 - 7 years now. This worked well with Gmail, no issue. Since July 2025, an update came through in Firefox and now an issue with Gmail. The mail opens properly but after 5 to 20 minutes the responsiveness slows down to stop. A pop up above the mail view states that Firefox is causing the slow down and there is a button to press to stop the issue. When pressed, the mail screen is frozen and I have to exit the G mail and restart. I have uploaded the most recent version of Firefox.

Firefox Ver 143.01.1 64 bit.

Windows 11 Pro

Cannot find the version of G mail used, but it is the latest update.

I have contacted G Mail about this issue as well.

How to resolve the issue, going on since sometime in July? I was hoping that a recent update by Google or Firefox would resolve, but it has not.

Very annoying especially when corresponding or trying to load attachments. Please help.

I was on the ESR channel and after the recent updates to 142.01 or 141 the ESR is missing from the about Firefox. I had got the tab groups option a few updates back and liked it. This latest update changed how a tab group collapses, instead of showing only the tab group name and collapsing all the tabs it leaves one open wasting space when I have several other tabs open. At least I don't see any sign of the annoying AI junk getting in the way yet. I thought you had a choice to stay on the ESR channel according to this link and others. https://support.mozilla.org/en-US/kb/firefox-support-windows-10-end-support I'll probably be forced to update to Windows 11 to do my taxes next year but I thought at least I could stay on the ESR channel to avoid new features getting in the way.

I've noticed that occasionally, a site will show up twice in the history dropdown. It's not always a thing that happens, but it does happen. Clearing history obviously wipes this out, but I'm not sure why it's happening in the first place.

I'm not talking multiple pages sharing a listing or anything. It's literally instances where certain sites will just show up twice in the history. I've noticed it seems to happen a lot when I open a video in Youtube in a spare tab rather than just clicking on a video on the main page.

I'm on version 142.0.1 of Firefox, and just updated to it two days or so ago. I'm on Windows 10 version 1909. Anyone know what's causing this?

Edit: I'm including an image of the glitch. This happened just after I clicked on a video. I did not hit reload or anything, and the video simply appears in the history twice. It occasionally happens with other sites, too.
