Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

Hi!

I've noticed dropped frames in videos for a while now, but only recently tested the issue. Using youtubes stats for nerds, I found that when videos have a small viewport resolution, it starts to drop frames. (I would test with other sites but only know of youtubes stats for nerds system to detect issues like this) For example a viewport resolution of 1250x703 does not drop frames, however by unmaximising the screen and the viewport resolution drops to 681x383, it begins dropping frames.

Using my 2nd monitor which has a smaller actual resolution, the video drops frames unless fullscreened, see recordings below. Test A | Firefox Maximised but video not fullscreen Test B | Firefox Maximised and video fullscreen This issue also occurs with picture-in-picture mode.

Disabling hardware acceleration fixes this issue but for some reason only affects firefox, using MS Edge with "graphics acceleration" enabled does not result in this issue. Is this potentially an issue specifically with how firefox handles hardware acceleration? Also since I require hardware acceleration to be enabled for 3D model work in my browser, is there something I'm missing here that would allow me to keep hardware acceleration on but not have this issue?

Any help is much appreciated, thanks!

Since the last update, the firefox taskbar icon is showing a strange shopping card icon? How can I remove it? I am not shopping with Firefox, I am using it as my web browser.

Ever since Firefox updated (to 147.0, I assume), I can no longer get ChatGPT to work. It does nothing when I click on "Log in" (I have a ChatGPT account), and the up arrow that you hit (or enter button) after asking a question does nothing (and the up arrow stays greyed out even while you are typing the question). I can use ChatGPT just fine on my Safari browser and iPhone. I used my iPhone ChatGPT to take me through steps to help, and it had me do several things (all of which did not work). These included: 1) refreshing the page/restarting; 2) open chat.openai.com, clicked lock icon and clicked "clear cookies and site data" and reloaded the page; 3) did same and clicked on the shield icon and toggled off "enhanced tracking protection"; 4) Went to file and "new private window", then chat.openai.com; 5) went to "about:support" in Firefox and clicked "refresh Firefox"; 6) Went to Firefox Settings, then Privacy & Security, then Permissions, then Block pop-up windows, then clicked exceptions and added "https://chat.openai.com"; 7) Then to Firefox Settings, then Privacy & Security, then Cookies and Site data, then manage exceptions, then added also "https://openai.com"; 8) Then changed enhanced tracking protection to Custom and unchecked cookies (cross-site tracking cookies) and restarted Firefox (I have since rechecked the box); 9) When I log into Firefox, it was showing a banner that read "Your privacy matters. Firefox now securely routes your DNS requests whenever possible to a partner service to protect you while you browse." Chat said to click "Disable" for this.; 10) After refreshing Firefox I chose (the 2nd time) "Restore only the ones you want" and opened a new tab. 11) At one point, I hit "Log in" for ChatGPT and the screen went slightly blurry and a new small rounded rectangular box (about 3 inches long) popped up, and Chat told me to hit the "X" to close that box, it then said to right-click on "Log In', and to choose "open link in new tab", but that option was not available. Chat says Firefox is still failing to load the embedded login frame, even after refresh. 12) I logged into "https://chat.openai.com/auth/login, and that still didn't work in Firefox, either. 13) Finally, I changed to Safari and successfully logged in. But I prefer Firefox as my main browser and want ChatGPT to work! I've even tried adding it to my sidebar (the new feature), and the same problems are occurring. It won't let me log in, and I can't ask it any questions. Help!  :)

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

On Firefox browser, I cannot Copy a file in Studio Code Server (within Home Assistant). SCS is open in HA in a Firefox tab. I get the error popup "Unable to read from the browser's clipboard. Please make sure you have granted access for this website to read from the clipboard." "Learn More" links to https://code.visualstudio.com/docs/remote/codespaces#_how-do-i-allow-vs-code-to-access-my-clipboard-for-reading and the "How do I allow VS Code to access my clipboard for reading?" section. But I cannot find similar settings in Firefox's Settings menu.

Any suggestions please on how to resolve this? I'm sure I used ~ a year back to be able to Copy a file ok in VSCode on Firefox. Thank you.

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.

I run a Synology DSM server on my local network. The website page to load locally inside my LAN is along the lines of 127.0.0.1:1001.

MacOSX 15.0.1 FireFox(FF) 132.0 (aarch64)

Previously accessing the DSM via the local IP address worked fine with no problems. Now, following one of the last couple of FF updates, I get an "unable to connect" message.

I also have a domain that routes to my local server and I can still access the DSM via the internet http address through FF. So I know that DSM is running fine and I have verified the settings within DSM.

I can load the DSM via the local IP in both Safari and Chrome. Only FF says it's unable to connect. So that shows that my DSM settings are fine and the page is available and loads in Safari and Chrome via the local IP.

I searched the forum and found similar postings, but not quite the same issue as mine. I deleted the cache & cookies/site data. I ensured the Proxy mode in FF is set to "No Proxy". I do not have any extensions running or themes.

I am at a complete loss at what setting in FF I need to change to restore this functionality.

Thanks, Matt

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.

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen

So, I recently updated my copy of Mozilla Firefox, and I noticed something strange. The button for the built-in VPN is disproportionately large to other buttons and clickable elements. I don't see it in the release notes, so I doubt this is an intentional design choice by the UX team, at least I hope it isn't. Any help will be greatly appreciated, as it is really distracting.

If it helps, I'm using Mozilla Firefox 151.0.2 running under GNU/Linux Debian 13 Trixie as a Flatpak.

Hi, I used Firefox browser at work since it had the best add-in for tab groups (Simple Tab Groups). Unfortunately browser is not supported any more. Is there a portable version that can be run without installing, from Mozilla.

I read a post that indicated it was available from PortableApps, but am not conversant enough to know that it's 100% safe. Believe that it was able to be updated as well.

audio stops completely for exactly 0.4 seconds when un-pausing video, this affects any "interruptions" including skipping around, clicking on timestamps and any ohter type. issue stops completely when another youtube tab with a video playing is currently active.

i have tried any regular troubleshooting tips, including any and all forums i've found online to no avail. this is not happening in any other browser.
