Firefox 技術支援討論區

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

Firefox began returning a PR_CONNECT_RESET_ERROR error on all websites a few days ago. Chrome likewise. MIcrosoft Edge is working fine. I am running Windows 7 with Kaspersky. I tried turning off the Windows Firewall and the Kaspersky protection, but it didn't help. I also tried disabling plugins, theme, and add-ons but it still didn't help. Any suggestions?

Hi, so yesterday, I updated to the latest version of FireFox (version 105.0). Nothing seemed to be out of the ordinary until I decided to watch a few YouTube videos. The best way I can describe this problem is that every time I decide to scroll down to see the description or read a few comments, the entire screen on my laptop goes black regardless if it's on default view or full screen.

Even though that does sound like a crash, the audio still plays, and if I power the computer to sleep mode and log back in, the window of the video automatically scrolls up and everything is back to the way it was (but I did had to restart the laptop once because it also visually broke my mouse pointer). The only way I can get around this problem is to pause whatever video I watch and then scroll down, and no black screen occurs.

I don't know if I'm the only one who has this problem, but I've never had this issue happen in past versions of FireFox. If there is another way to fix this problem, I'll be glad to take anyone's possible suggestions/solutions.

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

Secure Connection Failed

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

I've been utilizing the security protocol app DUO for work purposes for the last year with Firefox, no issues. I just recently updated to 105.0.1 and received the following error message when my DUO was prompted:

• "We're sorry, access is not allowed with Firefox due to security concerns." - with a sad face.

It then shows me a list of compatible browsers and FF being the only one not allowed to use the DUO authentication. I've attempted to clear my browsers cache, fire up FF once more only to arrive at the same messaging. I've uploaded a screenshot of what I ran into.

This has to be some sort of error as I've been utilizing FF and DUO together successfully with no issues over the last year.

Any help is greatly appreciated.

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

Firefox bowser stopped working suddenly. Tried uninstall and install multiple times with multiple options.

Still not working even after cleaned all Firefox related files using uninstall tools and installed again.

Hello!

I often log in to a service ticketing website to help my customers. Before emailing them I must reference the service ticket number somewhere in the email, but this is very difficult to do in Firefox. If I inspect the element this is what I see:

<em unselectable="on" style="width: 2161px;">Service Ticket #55474079</em>

I understand the unselectable attribute is on but even if I try setting it to off or deleting it all together the problem remains. Moreover, I've tried it in several browsers (Chrome, Edge, DuckDuckGo) and it works fine without any extensions or tricks.

In other words: only Firefox keeps me from selecting this very important piece of info.

Any help would be very much appreciated! I looked up help articles but nothing similar to my case. I did find an extension for the browser but I am afraid to try it due to security reasons.

Thank you!

BMET1.

I get so choppy scrolling that my eyes hurt after few minutes. Doesn't happen on Chrome or Edge. It is most noticable on YouTube. It feels like it's running at 15fps

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

Firefox recently stopped playing embedded youtube videos on my phpBB forum site?

i keep the latest firefox and only recently showed up embedded videos play fine on Chrome and others

here's a link to my forum which includes an embedded Youtube video demonstrating the issue, does it play on your browser? (ONLY firefox has an issue on my computer, chrome, etc. work fine)

thanks for any tests/insight into what might be causing the issue

ADDITIONAL COMMENT: why don't you include a date on these posting? a lot of wasted time on old posts? and also need a 'Preview' on these before posting?

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Hi. When opening the Microsoft Website (answers.microsoft.com) i experience some memory leaks. See photo for details.

Someone knows why?

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

My system is: Ubuntu 22.04.2 LTS Processor: AMD Rysen 5 3600 6 core procesor x 12 Graphics: AMD Radeon rx 5500 tx

Thanks.

I've started getting this error message on certain websites (always the same ones):

The page isn’t redirecting properly

An error occurred during a connection to www.manek.org.uk.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

The same websites still work fine on Firefox mobile, so it's nothing inherent in the sites themselves.

I have only noticed this in the last few days. I had just updated Firefox to version 109 – but it's not specific to one version of Firefox either, as I tried on one of my Macs which hadn't updated yet and is still on version 107, and the issue was replicated exactly the same.

I have tried clearing the cache, restarting Firefox, etc.

Can anyone help me resolve this? Some of these are websites I use quite a lot for my work, and it's frustrating to have to do anything just on my phone.
