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The articles on restoring from backup are outdated.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 Thunderbird on laptop. I make changes to a contact in the address book and they seem to be made. When I close Thunderbird and restart it, all changes are lost and are back to what the contact information was before. This has to be fixed.

For a few weeks now we have been unable to send emails through tbaytel server via Thunderbird. We get SMTP error. This happened after recent upgrades to Mozilla. Any idea when a fix will be out?

I've been using kelly blue book to research new cars. Yesterday it would load the vehicle information, but when I click on the blue box "see pricing" it just reloads this page. Has worked fine for the past week or more, but yesterday started doing this?

My Firefox VPN is still showing as nearing my limit, despite it now being October everywhere in the world. Why hasn't it reset to 50GB? I've tried restarting Firefox and it didn't make any difference. It still shows "Getting close to your VPN limit. You have 2.2GB of 50GB left this month."

When using shift+tab or ctrl+shift+tab to cycle between tabs in a window, firefox will occasional skip across one or multiple tabs. This will also happen when clicking tabs directly with the mouse. The tab that should be selected shows briefly before the browser automatically switches to one of the adjacent tabs. I do not have the setting "Ctrl+Tab cycles through tabs in recently used order" enabled. This doesn't happen for any specific tabs or windows consistently, and it doesn't specifically happen to unloaded tabs.

I'm running the current 157.0.1 release on Windows 11, and specifically am having my emails from the AP be sent to spam even though I have a specific filter set to tag them. I feel as if the filter itself is set up properly because when I manually run it the messages will be moved from the spam folder to the inbox and tagged accordingly.

The one thing sticking out to me is these emails are being forwarded through my relay account. I've tried changing the filter to work based on the relay address, but again it only works when I manually run it. I've also tried setting the filter to run both before "and" after spam classification, but neither option works. Ideally the filter would work without me having to go to my spam and run it, and even then I'm wondering why the spam filter hasn't learned by now that those email belong in my inbox.

I'd appreciate any help or solutions; I'm not an email power user or networking wiz though so please try to keep it as dumbed down for me as possible!

Title. 156.0 had NVIDIA Video Super Resolution working just fine. 156.0.1 has broken it on my setup. Nothing I have done has brought it back - toggling settings, clearing caches, forcing it on in about:config, etc. The plugin seems to be broken.

Was working just fine for over a year prior.

Latest Stable Firefox 156.0.1 RTX 5080 Driver 596.49 (May '26)

Does not show as working in the Control Panel, and is clearly not working on any video site. YouTube, the BBC, and Twitch were the ones most tested.

Please consider a fix. Thank you.

I have been having random crashes Firefox Snap on Kubuntu 24.04 (and now 26.04). Sometimes Firefox will run stably for over an hour, sometimes it will crash in less then a minute from (re-)launch. I have tried the usual troubleshooting steps of 'run in troubleshoot mode', 'refresh', disable plugins, but the crashing seems to happen even when running in troubleshoot mode. I also have not been able to figure out any kind of event or user-action that triggers the crash; it might happen while browsing, it might happen while I am not even at my computer. At first I thought 'the Devs will handle this', but it has been some 6 months so I think my case is not very common/pressing to the community. I'd like to take a more proactive approach in solving the problem. I am still a novice at software fixing, so I might have skipped or missed a very basic step in the '10 things to try to fix Firefox'.

I disconnected a Google Workspace account - Calendar and mail - from a former workplace. As far as I can tell, it's been deleted from Thunderbird.

However, I'll still get dialog boxes and an occasional browser popup asking me to reauthorise it.

How do I get rid of it once and for all?

Ever since the last update, I can no longer watch recordings on xfinity stream with Firefox. What happened? Can I fix it? I sometimes have to start watching programs late, but they wont play while recording. I can watch those same recordings when they are finished, but not while they are still recording. I can watch those same recordings while recording on Chrome and Safari so it's not an xfinity problem. But for some reason not on Firefox anymore Is there a setting I need to change? Thanks Ron

I have been on Windows 11 for years. While trying to fix a password issue, I learned that Firefox thinks I am on Windows 10 whose support is going away. How can I tell Firefox that I am on Windows 11?

Related issue: Firefox no longer likes my password. It has 8 characters, but only letters and numbers. Things got messed up while trying to fix it, so I am not sure of my password anymore. Apparently Firefox and Mozilla have separate accounts. I don't know which system's password is broken.

It was suggested that I clear cookies and cache. I cannot find the menu to do that. Trying to fix each problem just creates more problems! I need some support to straighten things out.

I always have Youtube playing in the background while I'm online, whether I'm playing games or browsing in different tabs. Usually after a video is done it autoplays the next one in Picture-in-Picture mode, but for the past week or so it has stopped. If I'm browsing in a different tab or playing a game in a different window I have to switch back to Youtube to put it back. I have 'Keep playing videos in Picture-in-Picture when switching tabs' turned on. I've tried turning autoplay permissions as well as autoplay on Youtube off and on again and none of that worked. I've also tried using both the Picture-in-Picture button next to the site link and the Picture-and-Picture button on the video itself. Please help! This has been very inconvenient. It interrupts my focus and sours my mood when I'm constantly having to re-open Youtube to continue watching videos.

Sorry if this is addressed elsewhere but I could not find it. After a recent update Firefox (Windows 11) started each website file download (mostly pdfs) at the Downloads folder. Previously, it would start at the most recent folder to which I downloaded a file. Since nearly all of my downloads are in a few neighboring folders way down the folder tree, I now have a ton of navigating to do for every single download. This is not sustainable. I have done a lot of Googling and investigated several suggested changes to about:config. I changed browser.download.folderList from 1 to 2. I made sure that browser.download.useDownloadDir is false. No effect. Any other suggestions? I am considering abandoning Firefox altogether. It has issues with some parts of the Medicare website. And an earlier update seemingly eliminated my ability to set a particular web page (Google) for new tabs, due to which I often wait a while for the page to appear, then realize I must click on Home. I like Firefox , but too many issues are accumulating and I can't seem to find solutions. Thanks for any help.

После последнего обновления вкладки, строка браузера, окно загрузок и некоторые кнопки стали иметь закругленные края. Как вернуть старые? Либо полностью квадратные, либо с небольшим радиусом закругления. Текущий слишком "круглый".

I use Firefox to read a lot of PDFs. Some of the documents have their own internal sections embedded into them. Because of this, Firefox PDF organizes the page numbers in a strange way. Instead of just page 1 through page 112, each section will have its own numbers starting over from 1. Thus, when I try to skip to page 3, it doesn't actually bring me to page 3 of the entire document, it brings me to page 3 of whatever section I'm in.

A large part of my job is digging through documents, and I don't have time to try and figure out which section of the document I'm in. I need page 3 to be the actual page 3. And I refuse to go back to Edge or Adobe.

I know there's a way to fix this in about:config because I've done it before on a previous computer, but I recently got a new computer and all my settings are gone. How to I turn on just regular page numbers in about:config?

A colleague of mine had Firefox logged in with a Mozilla account, before their computer needed to be reset, we checked and Firefox said Synchronisation was on and last succeeded 1 second ago. We proceeded to undertake the reset, but after logging back into the same Mozilla account, none of the bookmarks returned, nor did any saved addresses, passwords or browser history.

I was wondering if there is absolutely anything that we can do, or whether someone at Mozilla are able to check the account just in case?

I'm fearing the worst, and partially expecting it, but wanted to log here for sanity's sake, just in case.

Many thanks Ben

Hello,

Ever since the last Firefox update (on October 30th for me), the text on my inactive tabs has been painfully blurry (picture attached). I previously restored Firefox to default and seemed to have pinpointed a certain extension as the culprit, as well as a file within the profile named addonStartup.json.lz4. Deleting both seemed to have done the trick. However, my issue is now back, I can't find the previous file anywhere in the profile, deleting all the files in the profile that were created on the day when the problem reoccured doesn't fix it either. So I'm kind of at a loss. I have tried to set "gfx.font_rendering.cleartype_params.force_gdi_classic_for_families" to "Arial,Consolas,Courier New,Microsoft Sans Serif,Segoe UI,Tahoma,Trebuchet MS,Verdana" and "gfx.font_rendering.cleartype_params.force_gdi_classic_max_size" to 15 in about:config ; as this is an old fix I've seen for an older similar problem, to no avail.

Thanks in advance for your help!
