Firefox 技術支援討論區

A few days ago Ubuntu (22.04 LTS) showed me a message saying I can upgrade my OS (or something along those lines). I click on agree (any button that would let me proceed) and the upgrade took place (without restarting). Along with the upgrade Firefox was also updated to its latest version at the time (119.0). Since then, videos on Twitter play but without sound. On some other websites also none of the videos play. On YouTube, Firefox shows me a message saying "To play video, you may need to install the required video codecs" but the videos play fine; I haven't tried other websites but I assume all would have some issues. Google Chrome however doesn't have this issue and all videos play without any issues.

Note that I have not restarted my computer since the upgrade. I doubt this could be an issue but please let me know if you think this could be the issue.

I did the followings and restarted Firefox but none have worked so far for Twitter and some other random websites that I come across, but they resolved the issue for YouTube and now YouTube videos play, although I still get that codec message at the top of the tab:

sudo apt-get install ffmpeg sudo apt install ubuntu-restricted-extras sudo apt install libavcodec-extra

Someone told me this is because the default Firefox on Ubuntu 22 comes as a snap package and I should install the APT package manually instead so that it works. I prefer not to do this because I have lots of tabs open and have manually changed lots of the settings (including in about:config) that I want to preserve. I would also like to preserve the history of visited websites and keep the current cookies (don't really want to keep entering username/password on the same websites again). So the best way for me is to fix the issue for the default Firefox on Ubuntu 22.

Could you help me figure out what I should do to fix this issue?

Hi there, Last night I installed some new hardware into my PC, new motherboard and CPU for example. After that, I booted up the PC, everything worked completely fine and I was able to listen to Youtube / Twitch / Spotify etc. through Firefox.

This morning I boot up the PC, everything still works perfectly and I have audio coming from all other sources EXCEPT for Firefox. I have browsed every forum already but can not find anything that relates to me. I can't set my output device, since Firefox doesn't show up in the volume mixer. The tabs aren't muted. I have restarted Audiosrv and Windows Explorer several times. I have re-installed Firefox twice. I have tried booting it in safemode. All of the above hasn't resulted in a single second of audio. I am at a loss.

Kind regards, Siem Hoefnagels

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

With the latest update domain guessing is no longer working. I like just typing the name of the website and having Firefox add the prefix (https) and suffix (.com, org, etc. so I can move aorund the web just a little faster. The setting I used to turn it on is no longer in the about:config menu. Is there a way to get this back? For example, I was able to type in Amazon and the amazon.com website would automatically open in the tab. Now I get this

I tried to watch a youtube livestream today and it failed to play. Non-live videos on youtube are playing, even the same videos watched as VODs after the stream ends, but the livestreams are providing "Your browser can't play this video" errors.

Simultaneously, I'm noticing that some videos on Reddit (such as embedded tiktok videos) are stuck with a circling ring and won't play. At least some of the same videos will play on Tiktok (when I can find them).

ALSO, when I try to watch videos on my Nebula subscription, I'm getting a "This video could not be loaded: 4" error code. ANY video on Nebula.

What the heck gives?!

like the subject says the video on disney plus is very choppy/blurry/not 4k like it should be can u guys look into it? the video is blocky and blurry on firefox but not on chrome for some reason and id like to fix it soon

Hello team firefox....I am using your browser since Ages(hehe my father sggested it over edge)

There is feature called Search for text when you start typing Not sure about name AI suggested this name but i want to turn this off....I have attached a image where in the bottom of image you can see a search bar is shown I want to disable it, Now it is really annoys me whenever i start typing or searching for something

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

I can't 'talk' to my gateway. I logged in as admin, but that was all. I don't know what version of TLS my gateway supports and FFox doesn't support. What does that matter to sensible people? It's in the local network for goodness sake.

I could generate even 3000 tabs when i was peaking reading philosophy... Browsers are so moronic and UI didn't change since 1999, is there some addon for managing large amounts of tabs and organizing them, saving them for later? It is information age, we literally work with so many information, yet UI is so moronic it leads to information overload, not to mention i can't work efficiently like this...

I booted up firefox and clicked on youtube and I got the message please diseable your adblocker. I specifically came back to firefox after a year or 2 of not using it because I read that it will be intependent and will have working adblockers on youtube even when Microsoft edge,Opera and other browsers will bend the knee to Google. So what happened??? Why did the adblockers stop working on mozilla firefox? I have windows 11 and ublock origin as my add blocker. As it was recommened by most sites saying it was the best way to dodge youtubes anti-adblocker system. But now my adblocker no longer works on youtube.

I installed a user.js script to my profile, and even after deleting the file itself, the settings keep changing to what it wants, despite the file being deleted.

I've been troubleshooting this for a few hours now, and i surmise it got embedded in my firefox account somehow, because when i close firefox in task manager i can see a bunch of firefox processes doing stuff for about 30 seconds, and if i launch firefox again after that my browser is messed up.

In window's firewall i set a rule to not let firefox send and receive packets and while a block on receiving didnt do anything, the block on firefox sending data did prevent it from applying that fking user.js script. However, if firefox cant talk to websites its obviously useless, so im stumped.

I have deleted every single folder on my computer firefox uses, including cleaning the registry of its things aswell, so it has to be downloading that script from some server, but i havent been able to figure out from where. I assume its attached to my firefox account because, where else could it be getting the script from?

When i was installing the user.js script, i had no clue it would be so damn hard to get rid of. Thank fuck i have a backup of my profile.

When opening a file from another drive, I get an error: Access to the file was denied

I know this can happen on the Snap version, but I have Firefox installed from a deb!

Since the last couple updates Firefox is NOT allowing my Password Manager to fill in logins, usually after clearing the cache which I do once a week, at least. Why is that?

Second: Your browser is being managed by your organization. That is not true. There is no organization, there never has been, I'm retired and this is home use desktop running Windows 10 and no one but me has EVER managed Firefox and I've used this browser, though no longer as my default, since it first became available. So why does it think anyone but me controls anything about it?

I am worried now.

I hope it is a glitch and not something serious.

Today I powered up and wanted to go to a site. (password saved in FF)

Nothing popping up.

Strange.

Go to the about:logins page. I get this: (See picture)

I can't log in.

Should I be worried?

I've posted this before, but I can't seem to find it on here plus never got a response. This weirdness happens out of left field on multiple different sites but very infrequently and only when I'm using the most-up-to-date Firefox browser. I'll be surfing the web sometimes for hours, and then all of a sudden, the screen will start glitching. It seems like Firefox is also opening either copies of that page or last night it opened some from 2 years ago which makes no sense as again, I haven't visited them in 2 years (they're dated news feeds so I know when). So I'll have at least 9 tiny screens (they're not browser pages as there's no header or close button) full of either copies of what I was just viewing or old pages. Also, this causes my computer to have slow responses so it will take 20-30 seconds to get a mouse click to register (like trying to close Firefox or opening task manager). This requires a restart which almost always fixes the problem.

I have no malware, and before last night and this morning, I hadn't had this issue for over a week. This had started about a month ago after over a decade of using Firefox with 0 issues. This has been on numerous different websites too so it isn't just a bad browser interaction with one site's code either. This is on a fully updated Windows 11 PC with an NVIDIA video card and an I7 Intel 8-core processor.

I've been trying to export my bookmarks to an external hard drive so that if something should happen to my computer I have a file of them. I'm using Windows 11.

When I export the bookmarks as an HTML file, it saves OLD bookmarks from a few years ago, not the current ones. I know this because when I go to my external hard drive and click on the file and open it up it shows the old bookmarks.

I have no idea why this is happening. Can anyone help me? Thanks.
