I have all of my settings appropriately set according to all recommendations and instructions. When my Firefox opened it had a notice that it had updated. However, when it opened ALL of my previously opened tabs were gone. I need them ALL restored since I am a business owner and masters student and rely on them being readily available.

previous tabs not opening on initial boot up - I have it check for that to happen, but only a single tab opens when I boot up computer. I can find the last session in "Recently Closed Windows"

Hello guys, as in title - I use custom NextDNS set of rules on DNS-over-HTTPS. As of today, Firefox can't connect to the provider. AFAIK Troubleshoot Mode is also affected. The other devices using NextDNS on my network work just fine and when I set the DNS to work system-wide as a kind of workaround, I don't get an issue. Same when I use other DNS-over-HTTPS options in the Firefox Preferences. Yesterday the problem didn't occur and I haven't performed any updates since yesterday - both Firefox and NetworkManager seem to be up to date.

Additional info: OS: EndeavourOS (Arch Linux) Firefox version: 129.0.2

If any other info is needed, I'll be happy to provide it to you.

I seem to have a problem with Firefox's builtin PDF viewer. Instead of black text on a white or gray background or something else sensible, I get black text floating over my desktop background in the part of the Firefox window that's showing a PDF. PDFs display fine in an external viewer, but that's just passing the buck, isn't it? Is there a way to fix this on Firefox?

I suspect hardware acceleration is the issue, but everything else seems fine, so I don't want to just blanket disable hardware acceleration. How can acceleration for PDFs alone be disabled?

When open firefox I have problem , with may sites that appear and I cannot use it. The same problem I have on work and house with mozilla firefox 64bit. I checked my pc with antivirus and for malwares but nothing I have. Please help

Dear Firefox specialist,

does Firefox plan to implement the functionality to group tabs? such functionality is basic for many other browsers. and it's strange to use add-ons for the most popular browser.

on restart/update, all my toolbar extension are large and unchangable, there was a small icons option before this `update` now, i cant change them, the top of the screen used up by toolbar bs i dont need or want in large format. Is this something overlooked and will be fixed shortly today, or is this a `look for another browser` situation ?

I opened BigFishGames today and have suddenly gotten an error message "For the best experience, please enable local storage in your browser settings. Some features are not available when local storage is disabled." I went to the settings and allowed exceptions to all the things (pop-ups, cookies, tracking, etc.). None of that worked.

As I couldn't figure out how to do this I went through your FAQs. Found someone who had the same issue on his MAC and followed the instructions given there by an administrator. That being to go to https://firefox-storage-test.glitch.me/ and run that test. It shows there's nothing wrong. BigFish still shows it's error message.

This is one of my favorite sites and I use it daily. Yesterday I was able to access it just fine, today I can't even get their login script to show up. I haven't had any Firefox updates in several weeks, either. Please help me resolve this issue as soon as possible.

Thank you! -Lisa W

I not really sure what is going on but about 2 days ago I started having an issue where I have no sound within Firefox. I have tried using youtube, ign, other video sites etc. This affects my primary speakers which are set as my default audio device. When I use my headphones, I do have sound.

When I use any other application whether it is steam and the advertisements built into it for game trailers etc, GoG and i'm running a game, running another third party app for games, I have sound on all devices with no issues.

I have checked to see if my settings are mirrored for each device and cannot find any differences. When running youtube in Microsoft Edge and Firefox, my settings are the same but only Edge gets sound. I have tried doing all of this with and without addons installed for Firefox. I have also disabled VPN, tried PC restarts and a fresh install of Firefox.

This is a continuing problem that showed up on version 127, maybe 128, and continued through 129, and now to 130.0.

Attempts using Firefox to play movies at HD (highest 6GB data resolution) fail. Using, for example, the Edge browser works fine. This problem showed up as noted in the first sentence of this post. Manually changing an obscure "about:config" variable from 1 to 0 did not fix the problem.

I just updated to 130.0, immediately tried to play a movie at highest resolution, it failed. Changed the obscure variable from the value it had, 0, to 1 and it failed still. Changed it back to 0 and it failed.

My firefox crash, I uninstall and re-install. i logged to my Mozilla account and the sync does not work. I don't have my password or my bookmark.

I still have everything on my phone How can I force the sync or retrieve data in an xml/csv file ?

I don't want to use passkeys, and it seems that every site is checking browser support and wasting my time with passkey prompts before allowing me to log in with a password. How do I disable passkey support in Firefox?

When I try to search using safari or Firefox, a pop up requires me to sign in to google. How can I stop this or work around it? Is there some way to change the search engine?

I was working on strengthening my passwords using firefox as my browser and roboform. I had a us bank site open also at the time. I did not change that user id or password. However, ever since then I am unable to sign in to my us bank site. It brings up the site but as soon as I click to sign in, it greys the screen. I am able to sign in to every other site I have tried on the firefox browser. I am also able to sign in to my us bank site on at least two other browsers without issue. What has happened and how can I fix firefox to allow me to use it? The us bank site is not an app. Thank you.

Hey, my Firefox suddenly isn't making any sound anymore, but everything else on my PC is working fine. The troubleshooting page didn't help at all either. I'm getting desperate—restart, reinstalling, etc. didn't help either.

While reading a PDF using Firefox PDF Viewer, I highlighted certain passages occasionally saving (using the print icon) for future retrieval. Later when I did re-open the file, none of my highlighting was visible. I have tried alternative browsers, various PDF readers, etc. without luck. I really do need that highlighting. Thank you

i have two computers. on computer 1, all is fine. on computer 2, when it restarted after an update, i got the error message -- "the bookmarks and history system will not be functional b/c one of firefox's files is in use by another application, some security software can cause this problem." this has NEVER happened before.

i found the "how to fix this problem" page, but i am completely baffled by it. what i want to know is what security software (i have avast apps) is likely to have caused this problem, and how do i fix it (i.e., what setting should i change?).

thanks for any help you can provide. i am NOT tech-savvy, this is the only time this has happened, and i've had both computers for years. they have both always had the same apps.
