I can not access my bookmarks links, the bookmarks are there, but the links to the internet is dead. I still have access to my home page, though the bookmarks links are dead. How can I fix this? Thank you for you help in this matter. Gary

New addons on Firefox become blank on restarting the browser.

They return when I manually disable and enable them once.

How to fix this? Doesn't happen to older addons.

Even when I open a new tab in Firefox, the focus remains on the address bar. I'd like to know how to fix this. When I open a new tab, the address bar gets the focus, which I find inconvenient. Is there a way or setting to prevent the address bar from getting the focus and instead focus on the search box in the middle? I've searched online and tried the "settings in about:config" suggested in the search results, but it didn't solve the problem. Is it impossible? Firefox 153.0.3 64it

Since update yesterday, new tab is empty. Whatever I do, open new tab, open new window, go to `about:newtab` manually, it does not load anything. The view is totally blank. I can navigate to other pages fine as it should though. Only New Tab view is broken. Diagnostic mode does not work. I don't have plugins that would affect New Tab anyways.

Images have not been displaying properly. Or when they display properly, the images may go blank when scrolling past them or hovering the cursor over them. This is specifically troublesome with buttons to click on to confirm "yes" or "no", "next" or "start" where the text within those buttons is not visible. I've included a screen shot showing how some of the images appear on screen. Thank you for any suggestions you may have.

I downloaded Firefox today and saw there was a VPN option but it is not working. It asks me to sign in and per the instructions the clickable icon at the top should now have an option to enable but it just asks me to sign in again. I am from Canada and it says my region is available for this program.

On my Ubuntu computer, I find that the New Tab extension does not update like in my Windows computer.

Does the extension update at the same time as on Windows? Is there a way to make Firefox update the extension since going to Extensions does not appear to do that for this extension like those I have installed myself?

Yesterday, Facebook started to take longer and longer to load a page. Whenever I tried to post something and it took forevahhhh for it to show up on the timeline. I had to reload and repost several times since yesterday. All other websites are loading up just fine, but Facebook has taken as long as 30 seconds, sometimes even more before it refreshes a page.

Then.. it got worse. All I could see was the Facebook logo in the middle of the screen and nothing else.

Then it got even worse. As of this morning, I can't even get any results when I google Facebook! I put Facebook into the search bar, click return -- and nothing happens, absolutely nothing.

I'm not seeing any problems with any other website. I have already restarted my modem. I have already cleared out the cache and the cookies. I have restarted my laptop three times. I even looked up Downdetector, but there aren't any problems with the website in general.

Those are all the solutions I've found when searching about this, but the problem is only becoming worse, with everything I try. If there's something I need to change in Facebook settings, I can't do that, because now Facebook is completely inaccessible.

This is only happening on my laptop. Mobile is fine.

Things like, "set firefox as your default browser" and "open firefox when you start your computer?".

I don't want pop-ups from ANYBODY, but especially not from the browser. It defeats the whole purpose of blocking pop-ups if the browser itself is interrupting me with garbage I dont need.

How do I turn these off? There don't appear to be any settings, and every google search brings up disabling pop-ups for every other site.

(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?

My VPN used to work perfectly with my South African sites. Since I've downloaded the new Beta version of Firefox, things have become unstable, and the South African sites - mainly my dictionaries (which I use daily because I'm a translator) - don't work any more.

South Africa is one of the countries on the list, but when I open the VPN now, it says South Africa is unavailable, which had never been the case before.

Please help me sort it out. I can't take screenshots of the problem. When I go to the country list from the VPN, the dialogue box disappears.

Постоянное отображение панели задач (до тех пор, пока не нажму на иконку браузера на панели дважды. Повторяется с каждым заходом в режим "на весь экран" ), при просмотре видео, в браузере, в формате "на весь экран" с версии 156.0. в других браузерах подобной проблемы нет, только в Firefox. Прикладываю скрин визуального отображения проблемы. С настройками самой панели задач проблем нет, перепроверял.

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

Hi, I'd like to remove the rounded corners ( they are too big) everywhere in the Firefox browser. The suggestions I've found online aren't helping me. Do you have a solution for beginners?

Is there a theme or some other way to restore the classic styling instead of having these pills everywhere? This UX doesn't even make sense...tabs used to connect to the page content they were displaying, now it's just some disconnected oval; I have trouble seeing which tab is selected now because it's all various shades of grey that are about half a bit of luminosity away from each other...looking for suggestions on the best way to restore some sanity to this UI...

In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.
