• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I don’t see the translation option in the menu. I am running latest Firefox (148) on iOS Translation used to work yesterday

This is supposed to be available according to this https://support.mozilla.org/en-US/kb/translate-firefox-ios

How do I revert the update that was forced onto my that changed the window where I view tabs of different pages? It has completely changed and it's frustrating and I do not understand it. I wanted to go back to the style it was. I am not very versed in technology and changes like this make things unusable for me.

I have a Mozilla Firefox login with hundreds of bookmarks, I've been saving for years. With the recent update, I was logged out. I tried to log back in with my saved password and email. The information I have is correct. The problem lies in the fact that I created that login & pass with a University email. After graduating,the ending of the email address was changed to @alumni.edu sort of thing. So now it's trying to send me a security code to login and I cannot receive it because of this change to the email address, thus I cannot get logged back into my firefox to retrieve my bookmarks. Please help.

I no longer have the primary email account I registered with Firefox (It was a paid for private domain that I discontinued a few years back). how do I make my second email address on file the primary?

Greetings from the Pokemon world I don't know what this you might be but I have taken the browser out of the split tunnel off my VPN but it is still coming up as my real IP address I don't know what's going on but any help at your earliest convenience will be much appreciated.

Please add an option to set a default language to translate into. I often have to translate Japanese webpages, and each time I need to scroll through the list of "Translate to" languages to find English.

When Facebook creates passkey Firefox asks for an USB to be inserted. I have tried to disable USB in the settings ("security.webauth.webauthn_enable_usbtoken","false"). But then Facebook just gets into a retry loop and I can't create the passkey. I use Windows 10, and USB is NOT enabled as an authentication option. I need to fix this as Facebook nags me (in e-mail) to create a passkey.

When I go to another app, and back, tabs have to reload, often loosing what was done in the page. I have set Firefox as "No restrictions" on my Xiaomi 15 Ultra (HyperOS 3, Android 16), but Firefox still seems to unload memory very frequently.

Since version 148.0b2 (64-bit), it's once again not possible to enter search terms in the search box of a new tab; instead, the browser searches in the address bar. I've had all the settings I found in the forums configured correctly for over five years, and they haven't changed. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Despite this, the search still occurs in the address bar. Now I'm back to the awful search in the address bar. How can I fix this? Please fix this bug as soon as possible.

Original: Set der Version 148.0b2 (64-Bit) ist es wieder nicht möglich die Suche im neuen Tap, im Suchfenster einzugeben, sonder es wird wieder im Adressfeld gesucht. Ich habe alle Einstellungen, die ich in den Foren gefunden habe schon über 5 Jahre so eingestelle, sie sind auch nicht geändert. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Trotzdem wird die Suche im Adressfeld geführt.

Jetzt geht es aber wieder mit der Schrecklichen suchen in der Adresszeile los. Wie kann ich dies ändern? Bitte diesen Fehler (Bug) schnellst möglich beheben.

Sometimes I want to enter arbitrary IPA strings into websites from my phone. I've tried finding a privacy-respecting way to conveniently do this and the best way I've found so far is to use the app Unicode Keyboard by Tim Wunderlich, available on the Google Play Store, and enter the code point for the IPA letters or diacritics I want. This works in every other app, but in Firefox, there are two characters I can't enter this way - the combining grave diacritic U+0300 and the combining acute diacritic U+0301. Even other combining diacritica work. I like researching and talking about linguistics and conlanging online, and sometimes this involves using those diacritics to mark tones. This is such an odd specific incapability for Firefox to have but it has persisted, since at least as far back as 2024. I've just had to enter those diacritics in another app and copy&paste them in. I can enter the diacritics directly as keyboard input in Firefox on Windows and GNU/Linux.

Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

I have a gpu rtx 50 and recently decided to use rtx super resolution to improve watching online videos but I can't make it work on firefox, I'm currently using the DEV Edition x64 latest version HW Acceleration is enabled and I also tried modifying via about:config the lines: media.peerconnection.video.use_rtx gfx.webrender.overlay-vp-super-resolution gfx.webrender.super-resolution.nvidia

It still doesn't work! tested in the other versions of firefox and it also did not work Using brave, chrome and edge..works normally without having to do anything. Does anyone know what it can be???
