Firefox Community Forum

I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

Firefox has "Open previous windows and tabs" ticked in Settings. I had to force restart MacOS, and upon starting Firefox again my existing windows are invisible. They are shown in the Window menu and when right-clicking the Firefox icon in the MacOS dock, however when I select one of the windows it does not become visible. Command+` does not show the windows either.

I can however open new windows.

I tried renaming xulstore.json per this old article with no effect.

How can I make the existing windows visible again?

• 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

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

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.

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.

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.

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

Hi,

I have logged out from some device (laptop) today. I had approx 150 tabs over there I would really like to recover. Is there any chance to get them back?

Kind regards Grzegorz

Win 11 Pro, Firefox Browser-Developer, 147.0b9, 64bit Problem recently occurred. Example it was working fine this morning and after turning the computer off and restarting later in the day this happens. The image below shows faded access to the password manager. Link that appear do not work: Log in at the header and link in password support highlight in the visible text portion. Thanks in advance for your help

All searches get blocked by reCaptcha, quoted as being caused by 'unusual activity on the network' After going through the "I'm Not A Robot" process the search is o.k., but this happens for every search. The problem does not exist if I switch to Chrome. How do I fix this?
