Hi,

After the last Firefox update, the "Open previous windows and tabs" setting stopped working, and I need to use the shortcut "Ctrl+Shift+T" after each start to restore the previous tabs.

Is there any solution for this problem or there is a way to downgrade to a version where "Open previous windows and tabs" works correctly?

My current version is 152.0.1 (64-bit).

thanks.

Every 3-6 months presumably when you update, it fully deletes all my login data from EVERY website, it has happened many times and is honestly so annoying. Please fix this.

I run the current version of Firefox (152.01) under Windows 11 Pro on a Dell Inspiron 15-3530 laptop. More and more frequently, I'm getting "Access Denied" messages when I click on a site link t56o an internal page. This happens on several sites, most notably Dell.com. I get the error in Troubleshooting Mode, and clearing the cache doesn't help. I've searched the information here, but all the responses seem to involve Windows 7 or Windows 8, not Windows 11. Can someone tell me how to resolve this situation in Windows 11?

Thank you.

I have always, for 15+ years, been able to use the system Print dialog box to create a PDF.

But as of updating Firefox to version 152.0 (aarch64), all buttons related to Saving a PDF, etc. send the document straight to the Printer to print a hard copy. There no longer appears to be any way to save a PDF.

Example scenario: 1.) Visit website 2.) Select Print (cmd-P, File > Print) and open the 1st print dialog box 3.) Select "Print using the system dialog..." 4.) Select PDF in the 2nd dialog box. 5.) You used to be able to save the PDF at this stage, opening Finder, naming the file, and choose the Save DIR. However, as of this latest update, even after the Finder File Name dialog box, hitting Save at that stage sends it to the printer to print a hard copy.

Pressing PDF, Save as PDF, Open in Preview, and Save as Adobe PDF all send the file directly to the Printer to save it.

I've got tons of receipts and things to save for work in PDF and FF was always great at this. What happened? Is this a feature or a bug? Any and all advice is welcomed.

Running macOS 26.5.1, M2 Pro, macbook pro.

Hello, Im using localized (Lithuanian) version of Firefox. Several updates back, Firefox started including russian and Polish in preferred languages by default. Personally i know how to remove those for myself. However, since im managing around 300 computers in a school. This starts to become an issue. In Lithuania we only have one official language. And when pages in a school start opening in foreign (russian) language this starts to be quite annoying. I would love to keep using Firefox but i need help.

I just bought my boyfriend a new iMac. We are having trouble loading many sites and platforms using the latest Firefox browser. The list is growing but includes Facebook, Meetup, Wikipedia, chess.com, nytimes.com - in all cases, rather than a login screen, we get an error message or a home page loads with no access to other pages or login area. I've cleared the cache, restarted, tried going directly to the site to log in, but nothing works. Everything is fine when using Chrome, but we prefer Firefox. Is this a conflict in the new Apple OS? Is there a fix?

The homepage for Firefox has not loaded correctly since the new updates of a month or so ago (maybe a bit longer). The windows all just scroll from left to right with no data. The widgets showing date, time, etc show up, but the 12 windows for stories just grey scroll left to right. Someone said it will fix itself. Ok. Any ideas out there?

(AI written summary of troubleshooting steps taken before making this support thread)

Firefox version: - 152.0.1 Release - 153.0 Nightly

OS: - Windows 11 build 26200

GPU: - NVIDIA GeForce RTX 4070 SUPER

Codec package: - Microsoft HEVC Video Extensions installed from Microsoft Store

Problem

Firefox does not expose HEVC playback support, causing Twitch to disable 1440p streams encoded with HEVC.

The same machine can play the same HEVC Twitch streams in Chrome immediately after installing HEVC Video Extensions.

Expected result

Firefox should report HEVC playback support and allow playback of HEVC streams, as Chrome does on the same system.

Actual result

Firefox reports HEVC as unsupported.

about:support:

codecSupportInfo: H264 SWDEC HWDEC VP9 SWDEC HWDEC VP8 SWDEC HWDEC AV1 SWDEC HWDEC HEVC NONE

Troubleshooting already performed

- Installed Microsoft HEVC Video Extensions - Rebooted Windows - Updated NVIDIA drivers - Verified hardware acceleration is enabled - Tested with a brand new Firefox profile - Tested with Firefox Nightly - Confirmed Chrome can play the same HEVC streams

Additional observations

Chrome: - Twitch 1440p becomes available immediately after installing HEVC Video Extensions - Twitch Stats for Nerds reports:

 hev1.1.6.L150.90.0.0.0.0.0

Firefox: - Twitch reports that the browser does not support the required resolution - 1440p remains greyed out - about:support continues to report HEVC NONE

Reproducible tests

Firefox console:

MediaSource.isTypeSupported('video/mp4; codecs="hev1.1.6.L150.90"')

Result: false

MediaSource.isTypeSupported('video/mp4; codecs="hvc1.1.6.L150.90"')

Result: false

navigator.mediaCapabilities.decodingInfo({

 type: "media-source",
 video: {
   contentType: 'video/mp4; codecs="hev1.1.6.L150.90"',
   width: 2560,
   height: 1440,
   bitrate: 8000000,
   framerate: 60
 }

})

Result: {

 supported: false,
 smooth: false,
 powerEfficient: false

}

For comparison:

MediaSource.isTypeSupported('video/mp4; codecs="av01.0.08M.08"')

Result: true

navigator.mediaCapabilities.decodingInfo({

 type: "file",
 video: {
   contentType: 'video/mp4; codecs="av01.0.08M.08"',
   width: 2560,
   height: 1440,
   bitrate: 8000000,
   framerate: 60
 }

})

Result: {

 supported: true,
 smooth: true,
 powerEfficient: true

}

Additional note

Setting:

dom.media.webcodecs.h265.enabled = true

causes HTML5 codec test (https://html5test.co/) to report H.265 support, but does not change:

- about:support - MediaSource.isTypeSupported() - MediaCapabilities.decodingInfo() - Twitch HEVC playback availability

Question

Is this a known issue with HEVC Media Source Extensions support on Windows 11 build 26200, or is there another requirement for Firefox to expose HEVC playback capability through MediaSource and MediaCapabilities when the Windows HEVC codec is installed and functioning in Chromium-based browsers?

I sell on vinted, which generates a PDF label to print. Some of the courier sites add a lot of nonsense text to their labels, which I cover up with a white box to save ink. These edited PDFs used to then print just the label without the nonsense text, but since a recent Firefox update they have started printing an empty page instead. Saving the edited PDF and then opening it again in Firefox does not work. The edited labels still print okay in Microsoft Edge.

when i updated linux a newer firefox version was installed but none of my personal settings, passwords or bookmarks installed onto the new firefox version. can't access my previous profil on my computer

When i go to type in something in google search it always wants to tell me the next words to type. How can i stop this because it messes me up when typing. Firefox is my default browser. PS: i have tried every thing that AI told me to do and nothing works at all. Thank You.

Those instructions don't work and I'm sick of spending so much time on this problem these days.

Now thinking it happens after an update, which is a problem because they seem to come just days apart. None of the solutions offered works because right-clicking on the top doesn't do anything. Nor does going into the settings in the app on my laptop or online. I've downloaded and installed the latest version of Firefox more than once in the recent past. I've also shut down my laptop and rebooted. Nothing works. It's extremely annoying not to be able to access the features that I use *all the time*! day. I'm using a laptop with updated Windows 11.
