I am using Windows 10 Enterprise N, Version 21H2 and installed the Media Feature Pack through the Optional Features tab. But even though other browsers have picked up on that and can play e.g. Twitch streams etc. appropriately, while Firefox still shows the `this video is unavailable or not supported in this browser` error message.

Hi there,

I upgraded my Mac Desktop OS to Ventura 13 yesterday and now my Firefox browser is not working. It opens very briefly and then the window closes immediately. The Firefox program is still open in my dock, but when I click on the icon, the Firefox window only opens for the briefest moment and then immediately closes again.

I tried to fix it: I have uninstalled and re-installed the latest version of Firefox twice and have rebooted my computer twice.

Has anyone has similar experiences and/or ideas for solutions?

Thank you!

People are having connection issues on firefox https://www.reddit.com/r/firefox/comments/x1um0o/browser_problems_after_1040_and_10401/

A fix for this is going to about:config

network.dns.disableIPv6 and set to true

Disabling ipv6 is a fix, but is this safe?

I think mozilla team should look into what exactly is making ipv6 cause connection issues.

CMD+Mouse Wheel to Zoom in Firefox for macOS [Fix Firefox 109.0 Intentional Bug]

Firefox 109.0 for macOS introduced an intentional bug that disables the popular highly useful zoom in/out using cmd+mouse wheel. Mozilla claims that this engineered bug "avoids accidental zooming and matches the behavior of other web browsers on macOS." However, it causes severe trouble for productivity users and the large user community who use a mouse and keyboard.

Could you please let me know how the highly popular and practical zoom in/out using cmd+mouse wheel could be re-enabled in Firefox 109.0?

Also, I would like to ask Mozilla to respect user decisions and let them choose whether they prefer to disable Ctrl or Cmd + trackpad or mouse wheel (scrolls the page instead of zooming) or use it.

Thanks

Hi,

After an update, Firefox does not recognize middle click at all. It worked in the past, but no longer. For example, middle clicking on... - a hyperlink should open a tab in the background - a bookmark bar item or bookmark menu should open that bookmark in background - empty space on the webpage should initiate autoscroll - a tab handle on the Firefox title bar area should close that tab None of these work as of now.

I'm on Windows 10, and I am using a Logitech MX Master 3 via USB Unifying receiver. I checked Logi Options+ app and confirmed the middle button is correctly set to middle button (default) and there's no per-app settings for Firefox.

For years, never a problem. Suddenly, the Roboform lower toolbox, while being checked in the latest Firefox options, will not actually show up. The Roboform help suggestions are numerous but haven't helped at all. Something somewhere has been changed and it's most unfortunate but I cannot continue with Firefox. Chrome does load the lower toolbar with no problems ever. I dislike switching but unless help comes soon, I will be forced to. I am on Firefox all day every day and am slowly moving up through coding systems.

When going full-screen on video, the browser doesn't show the full-screen the first time.

For example, when I want to view a full-screen video on YouTube/Disney/Netflix/Prime Video, I select the full-screen button as usual. However the top left-hand side corners always show a thin blue hue. The thin blue hue only goes away when I leave full-screen and re-select it.

Any ideas on what might be causing this? My browser is up-to-date

Until recently my browser accessed all the sites I have used for years and now I cannot access them. As an example the message I receive is "You don't have permission to access "http://booking.jetstar.com/au/en/booking/select-flights" on this server".

Reference #18.62052017.1660274157.1f6107dd Other sites like my banking site I can access freely on Edge but cannot on Firefox. No error message in that case, just says error try again. All this started after I loaded Norton. I have had them look at the system, and they have, but also point out that it is not them as I can access the site from Edge. I have looked at the help page and their are thousands of people with the same query but no fixes! As a long term supporter of Firefox I am disappointed that I now have to use Edge to do most of my business. HELP

I recently bought a new laptop and seem to have Firefox constantly crashing in both normal and troubleshoot mode on both a Windows 11 OS as well as Linux OS's (Pop_OS and Manjaro). In general it will crash every 30 minutes or so but sometimes it can happen rapidly in a row.

I'm not sure what the problem could be but it sounds like a hardware problem? However I don't seem to be experiencing crashes on Edge or Opera when I tried them but I haven't tested it for too long yet. Does anyone have any advice or insight about this?

Here are some recent report ID's:

Firefox (and also Thunderbird) crash on trying to load Yahoo mail login page

A friend (who knows even less about technology than me) has an old Dell Inspiron 1501 which has been running Linux Mint 18 Xfce, which is now unsupported. I'm beginning to regret it but just to keep it going for a couple of years I offered to update to Mint 20 Xfce, which is the last version listing 1 Gb as the minimum Ram (everything later or other version are 2 Gb or more), which is the most that system can use. Once the wifi was eventually working (old b43 broadcom driver) most things went fine (except Team Viewer, which works on another Mint 20 Xfce system, but that's not a question for here). However, she uses Yahoo mail, and for some reason just attempting to load the login page (login.yahoo.com) causes Firefox to crash (I mentioned Thunderbird in the title as I attempted to access Yahoo Mail with it, but because it needs to access the Yahoo Mail page (as I think this is now based on App codes rather than passwords), and doing that crashed Thunderbird also). I'm pretty sure I have methodically gone through all the troubleshooting steps on https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems (clear cookies & cache by deleting history; clear startup cache; refresh; reinstall; new profile). Firefox doesn't crash in Troubleshoot mode, despite the fact is seems to still use hardware acceleration, even though I thought it would disable that. Hence, I'm at the end of what I know to try (and that's just from following the guide, I am not an expert) and would be grateful for any help anyone can offer. I attach an image that lists all the submitted crash reports, as they will refer to slightly different conditions as I tried all the options mentioned above. I'm using my own PC to submit this (so any hardware & system data submitted by this web-form won't be relevant), not the Inspiron 1501 that has the issue. I can open the Yahoo mail page on this machine (same version of Firefox) and also on the Inspiron 1501 using Chrome (but there was a different reason relating to security why we couldn't log in via that). Would really like to get Firefox (and Thunderbird) working on the laptop, if possible.
