Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

I am migrating to a new laptop. The new laptop keeps asking me for a primary password. I have never set one up. This issue doesn't happen on the old machine, only the new one. It also won't let me disable the pop-up that asks for the primary password. Please advise.

I often have many tabs open (25+) I have made it so tab shrink way more then normal (I like the way chrome handles tabs where they basically just shrink infinitely. Firefox doesn't do it's even with my twerks but ohwell.)

so when i want to click on a tab with audio playing at a small size i often mute the tab instead of clicking on the tab

Where and how can i remove the mute button that appears when hovering over tabs with audio playing?

I have never found that mute button useful so removing it will not impact me

Sorry to have this same issue again, knowing full well it can happen after finding this some years ago (https://support.mozilla.org/en-US/questions/1319823), I tried to carefully connect two older PC devices back to firefox sync, however on one I managed to enable sync before disconnecting my profile (it seemed as if reconnecting sync temporarily was the only way to disconnect a profile from firefox's UI - I should have been more careful and removed the profile from the filesystem level): at which point I polluted the sync server.

I've noticed that `about:sync` has an option under bookmarks/engine actions 'wipe bookmarks', which sounds exactly what I need, and if I watch what happens once pressed it does the right thing and repopulates the sever with the 'correct' PC's bookmark set (when run from that PC), however it also says 'other devices will act like a reset', which i'm finding NOT to be the case: eventually one of my other device repollutes the server with bad bookmarks which propogate.

I'm thinking the culprits are my phones, If I wipe and do a sync on a phone, my phone's bookmarks stay polluted. If i'm right about that, I think my question is: can I wipe my profile (or preferably only my bookmarks) from my phones' Firefox without having to entirely uninstall/reinstall (or do you have any other advice for not re-polluting the server from some already-polluted device's bookmarks?

thanks in advance

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something fascists do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

All of a sudden, Firefox (125.0.3), running on Windows 11, is not delivering any sound at all on websites which have music or people speaking. The TOR browser does deliver the sound on those same websites.

On my Macbook Air M1, Firefox's UI and default scaling is perfect on my Retina display, but if I move the window to my external Philips 1080P monitor, some - but not all - interface elements are very over-sized, which makes Firefox unuseable on any external monitor I connect. (I have tested this with multiple other monitors)

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

When I use google meet, I regularly get feedback that I sound far away, despite being at a normal distance from my computer. If I switch to another app, like slack, the issue doesn't present (so it's not an OS level issue). I'm using firefox on m3 macbook pro.

What can I do to fix this issue? Or do I have to stop using firefox?

I recently had to reinstall Windows, as a result of a hard drive issue. This involved reinstalling Firefox from scratch.

As such I had browser.sessionstore.resume_from_crash set to false, but browser.sessionstore.max_resumed_crashes was still set to its default value of 1. The combination resulted in a browser restore after a crash...

This would seem to imply that browser.sessionstore.resume_from_crash has either been deprecated (though that is not mentioned in the knowledgebase article), or it is not being correctly interrogated in the code. Unless I am missing something, and I do not want to go thru the entire config to see what else I might need to set...

If I am reading this wrong, please let me know if there are other entries that need to change from default. In the event of a crash, I want the browser to start with my home pages, NOT restore.

Currently on FF 125.0.3 (64-bit) - and yes, I know there is an update waiting for me to restart my browser yet again...

Hi, this is going to be a long one, so many things... Using Firefox the latest Ubuntu LTS, with the latest Firefox from Snap. I'm a very long term Firefox user, never had any real troubles unit recently. I have a vast number of cookies, saved passwords and so on. Reinstalling or deleting cookies or such isn't an option unless fixes are guaranteed to work - if I have to start over then I'll do it with Opera, that is where my grumpiness indicator is at.

The set up is two monitors (working as a single 'screen') attached to an Aspire PC (Aspire X seems to be the model?). I tend to have 'stuff' going on in the left hand monitor, YouTube on the right. The PC is on all day. I know there are log files, but I don't know which is for what or where they are. I use AdBlocker Ultimate.

So what's happening is: Firefox crashes quite often at any time - 'Firefox is not responding - force quit or wait' - always have to quit. There doesn't seem to be any repeatable way to cause this, it seems random.

When the mouse enters the YouTube window (the drawing area, not the actual window) it disappears until the pointer moves out of the window. Jiggling the window size sometimes brings it back, but...

When the mouse pointer actually appears the window is completely unresponsive - clicks don't work, nothing highlights and so on. After somewhere between 10 and 30 seconds things will work for 2 or 3 mouse actions (clicks, drags etc) then do it again. Unless I give it plenty of time, clicking on a video will play a pretty random one - Firefox seems to lose track of where the pointer is.

If I comment on a video the I get about 5 to 10 characters in then nothing happens for 10 to 20 seconds, then any queued characters are shown. Rinse and repeat until the comment is complete - it takes ages.

YouTube is the biggest problem, but there are some glitches in other Firefox windows, I'm supposing that the problems are audio/video related.

None of the above happens with Opera. It's getting to the stage where Firefox is unusable.

I've googled and searched this site but the there seems no solution.

Any help appreciated.

I have to configure a lot of networking equipment! One day I might be working on a brand new piece of equipment and the next day trying to log into some ancient piece of equipment because I need to change something and I can't replace it yet. I'm having a major issue with the redirect even if I explicitly type HTTP it forces it to HTTPS ( and no I don't have HTTPS everywhere installed I've actually never used it ). I've noticed recently a few updates back now that if the connection cannot succeed it redirects to HTTP but it can hang up in a weird limbo where it thinks the site doesn't exist. There needs to be a toggle for local addresses explicitly typed "HTTP" to try that first. There also needs a toggle to ignore the security issues when accessing the device with a self assigned certificate as every single networking device has a self assigned a certificate and every time I need to change the setting on a router I have to agree even though I have a greed for the last 10 times when I've access the device or I just reset the device and the self signed certificate changed. And I don't know how you're gonna handle this on mobile but it almost makes using a mobile browser useless because I might as well just get the computer out even if all I have to do is change a password, SSID or just check a setting.

So local addresses need an option to lower the warning level for self signed certificates and to obey the typed protocol!

And there's some sort of bug with the Logic that detects a certificate or non-secure site that breaks when the connection drops. The only way I've been able to get around this is to go to the address bar and hit enter as a reload will not work and a reload skipping cash will not work to bring the site back up.

I've had devices that I thought weren't working only to find out they were working fine after 3 or 4 attempts and restarts only to find it's just that firefox thought the site didn't exist anymore.

And I don't have any other options because chrome is even worse with HTTPS once it gets it's vampire fangs in you're stuck it will not let you go back. And safari you might as will be undead.

Finally getting annoyed enough to write some thing as every time you go change your setting reboot device check setting log back in change saying restart log back in and you have to hit except certificate every single time.

And while I'm here Bring back the checkbox to save/ not save the certificate as I might not want to save the certificate when I know I'm going to reset the device and it's going to be totally different in the next 10 minutes. Or I might not want to save it at all like I go to a website that's misconfigured and the certificates not valid for the domain name that it's using.

Hi,

My Mozilla Firefox Web developer tool keeps autonomously toggling on/off in any Firefox window/tab..

Its as-if I'm repeatedly hitting Ctrl-Shft-I (which brings up the web developer tool in the bottom 1/4 of the browser).

I've checked all Setting, turned off all hardware acceleration as suggested for similar flickering problem (which wasn't on anyway).

I use Norton 360 Security Software but have Norton Safe Web disabled. The only active Extensions are Firefox Multi-Container and Firefox Sideview.

Its not doing it at the moment, but I'm not sure exactly what triggers it and expect it to happen again.

Last time it happened I was browsing Amazon. Hitting Ctrl-Shift-I only makes is turn off until start scrolling again, etc.

I don't think its virus related, because I use Norton 360, and Task manager "Performance Tab" show the computer is generally very mellow.

Please help, as I love Firefox, but this problem can drive one crazy.

Thanks Larry Zdanis

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

Whenever I try going on to a multiplayer (e.g. .io) game website it will not let me access its server. The website itself works fine and I can access it but as soon as I press play or anything else it just says 'disconnected' or 'trying to reconnect to server'. please see if you can fix this as I couldn't find anything to resolve this problem do anything.
