Firefox Community Forum

Hi folks!

My Firefox just updated and I'm now receiving the recommended stories (along with the widgets and recent activity.) when I open a New Tab. I was able to disable the widgets and activity and I see the place where I can turn off the Stories, but they are not going away.

In the "Customize" menu accessible via the pencil icon on the New Tab page, toggling Stories off does not make them go away; reloading the page, the toggle is re-enabled.

In the general Settings menu, accessible via the hamburger menu and under "Home and startup," I have Stories ("Exceptional content curated by the Firefox family") toggled off. The toggle does not reset, but the stories still display.

How can I fix this? Thank you all very much in advance.

Every time I start Firefox lately, it keeps prompting me: "You must log in to this network before you can access the Internet." I have no idea what this means and have no problem accessing the Internet in any case. What suddenly started causing this !#@%$ message and how do I turn it off?

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

Hello,

For few days, it's impossible to connect to FACEBOOK. I have the latest version of FIREFOX, but I have to use another web browser (EDGE) to connect to FACEBOOK. The problem is the same with my two computers with the latest WINDOWS.

Thank you for your help to solve my problem

My current version of Firefox is 151.0.4 (64-bit) & for the past 2 weeks or so every time I use the search bar to google something it triggers one of those "We've detected unusual activity from your network" requiring a Captcha. At first I tried all of the typical stuff [antivirus, vpn, extensions, etc...] to make sure that wasn't the issue. But as of yesterday & confirmed today I can actually go to Google's website first & do the search from there with no issue & no captcha.

So, whatever the issue is has to do specifically with doing the search via the search bar... for some reason. Is this a bug in the browser, or is there perhaps some setting that could cause this to happen in the about:config page? Though, I doubt a setting could be it because I've changed the settings I've changed now for years without causing this issue.

I'm trying to add the world cup tracker to my home screen, but when i click the link, it just puts me in my new tab page with no changes. When I click the pencil edit icon, widgets are not an option for me. Is there a place I need to enable them?

Je ne peux plus accéder à Facebook sur l'ordinateur. Attente éternelle de la prise en compte des mes codes. Alors que j'y accède normalement sur mon téléphone portable et sur ma tablette. Je suis protégé par Bitdefender. Quid ? Merci :-)

The SSL cert has been installed by the entity (Gridhost) from whom I have bought it for 20 years. And as explained, Firefox still shows it as Not Secure while Chrome say it is secure.

Hello

I have Firefox 154.0 on my 2 PCs that have Windows 11 and both computers are updated fully as of 22nd August 2026 with both Windows updates and Nvidia drivers.

Background: On my 2 PCs I have an "old" stationary PC with Geforce 1070 TI card, and I have a laptop Asus Vivobook 15 PRO with a Geforce GTX 4600 card. Both computers working fine and no issues so far.

Symptoms: I updated Firefox. Note! I always update Firefox on my computers, so it wasn't a clean install of the browser. And suddenly on both computers there were black artifacts all over screen and flickering when scrolling on Facebook or Youtube. Also even worse on sites were you drag a div and the browser turns into a 1-bit disco.

Workaround that seems to be working for me: I went to about:settings and searched for hardware on my laptop (the one with 4600 card) and searched for "hardware". Then I disabled the hardware acceleration thing, or whatever it was, but unchecking the result after search. Then I restarted my laptop not using hardware acceleration and it worked fine.

Then again I search about:settings for hardware and checked the bottom of the 2, not sure what the first one was. And restarted computer.

Now I don't have those black artifacts and flickering any more.

Not sure if that somehow triggered something that works for fresh installs or not.

Anyway... I can't submit a ticket since I can't reproduce the error it's no point submitting to Bugzilla. But hopefully this makes sense anyways... But I'm pretty sure you guys are aware of this issue already. But posting anyways in case it might help.

For about a month I've had to use Chrome because my bookmarks scramble or become unoperatable, then about 4 days ago they started saving again & all bookmarks worked fine. This lasted about 3 days then went back to becoming dead or wrong (may all say 1 or 2) sites I visit. a restart may lose any new bookmarks, & the rest of my bookmarks are either wrong site or dead links. How do I correct? I have tried new downloads & the new Firefox acts just like the messed up version. Probably a simple setting but I give up, can't find the solution. Any help appreciated. You have my permission to change any setting needed to fix Bookmarks. Thanks, James

I can't figure out which topic to use for this but I can't submit it without one.

When I click on the star icon in the address bar the star icon is filled in, and existing bookmarks do show with the filled-in star icon and they work. But I no longer get a dropdown where I can assign a folder, edit, tag, or delete an existing bookmark, and the pages I've tried to bookmark don't show up in Recently Bookmarked so they haven't been added. I don't know if it has something to do with the toolbar?

Nothing I can find online helps. The places.sqlite file in my profile is not read-only, and I refreshed Firefox (stupidly, before I took a screenshot of the pinned shortcuts on my New Tabs page) and that made no difference. The only extension I use is UBlock Origin. Changing profiles did not help. This is on my personal laptop and no organization controls my settings.

I stay up to date on Windows 11 and Firefox updates. I do use a VPN but it never interfered with bookmarking functionality before. (I see Firefox offers a free one now but I've got a couple of years left on my paid subscription).

I asked the community but got no replies. (I did "reply" to add more information which no longer applies, and I can't seem to delete the "reply".)

Thanks in advance for any help!

(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 have checked my mouse settings and reset everything but no change,,this started after a windows update, so i went in and uninstalled the update but did not fix the problem..i don't know how better to explain it, the scroll just stopped working while trying to scroll web pages,when i try to scroll the page doesn't move ., if i move my pointer over to the right side where the indicator of where you have scrolled to is and i click under it to scroll down and sometimes it kindof goes crazy and scrolls through many,many pages instantly...i hope all this some sense to you computer gurus cause i have tried everything that i know...thanks for giving it a shot..i use firefox browser and windows 11
