Firefox 技術支援討論區

So I have never had a problem with YouTube up until yesterday, anytime I try to watch a video and click play or anywhere on the video it just has a circle that spins in the middle around a youtube button, or sometimes just a black screen.

I have tried clearing Cookies & Cache, tried in safe mode, tried with a new profile, disabled hardware acceleration, I even uninstalled and re-installed Firefox.

Still for some reason I am unable to watch videos and only on Firefox, it works fine in Chrome and Edge browsers.

I am at a loss on how to fix this, and I really don't want to have to use two browsers for watching videos and navigating the internet.

Any Ideas?

Also my Internet is not the problem, I have Gigabit Fiber.

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

Hello. I don't know which Firefox release broke this essential feature. The problem started after I enabled Aero in my Windows 7 system. It happens often if I have an open tab with https://www.o2tv.cz/ which uses some DRM to play TV content.

My Firefox browser automatically updated a few days ago. Since the update, the browser now crashes repeatedly during basic browsing, making Firefox essentially unusable. For instance, retrieving Yahoo mail, reading articles, accessing login pages -- the page will enter some type of refresh/reload cycle and crash the browser.

I opened the browser in troubleshoot mode and the problem did not occur. Following the Mozilla instructions, I disabled extensions and reopened the browser normally, and the crashes continued. I have not taken any additional actions.

This problem began immediately after the latest browser update on 9/13.

I have noticed for awhile now that when I load my Firefox homepage its keeps taking longer, certainly longer than it used to take. Also, when I load a You-tube video it takes about a minute for things to work properly. The video and audio are erratic and skipping and simply disjointed for about the first minute, but then after that period of time the You-tube video runs OK, both audio and video. Something seems to be causing those problems recently that I didn't have previously. The problem seems to just keep getting worse also. I would appreciate any input and suggestions that may help the problem. Thank you.

For the past month or so, every time I launch Firefox, it freezes exactly twice:

1. After 5-10 seconds of just being open, it will freeze and stop responding to input. Any animations, videos, blinking text cursors, etc. in the current webpage continue to play as if nothing is wrong. After a second or two of being frozen, it will return to working correctly.
2. I can use it for a few seconds and then it will do the same thing and then eventually turn white and say "(Not Responding)" in the title bar, but always immediately after a click or keyboard input happens. If I open a website and then continue working in other programs, it will not freeze until I refocus Firefox.

Once both freezes have happened, everything works as normal until I close all Firefox windows and then relaunch it later.

I provided the full troubleshooting information report below (apparently it's not public!), but in summary: Firefox version: 117.0 build 20230824132758 OS: Windows 11 version 22H2 build 22621.2215 GPU: Intel Arc A750, driver version 31.0.101.4644 (8/11/2023). I know it's is unusual, but I know someone with an Intel Arc A770, also running Windows 11, who does not have this problem with Firefox.

This does not happen on my laptop, which is also Windows 11, and Firefox Sync is working between them. I'm also using Firefox Sync with my Pixel 6 and iPhone X and neither of those has any issue.

I have already tried:

• Rebooting my PC
• Running Firefox in "Troubleshoot Mode":' no extensions enabled, same behavior
• Running Edge: no freezing issue, but I don't want to use Edge for so many reasons
• Reinstalling Firefox: I ran the Firefox uninstaller, deleted %AppData%\Mozilla\Firefox, and then reinstalled. It froze the same way immediately after launching the fresh install, before I signed in and synced all my data back.
• Running sfc /scannow: No problems found, freezing still happening

Are there any further troubleshooting step I can try, debug output I can enable/collect, etc.? This is really annoying and I'm all out of ideas.

Hi I put "about:support" in the URL field. The pressed "Open folder" button on the profile folder section on the troubleshooting page, then I got an error: "Location is not available." I looked for the folder, but I could not. "about:support" describes the location "C:\Users\xxx\AppData\Roaming\Mozilla\Firefox\Profiles\forv3n79.default-release but the Roamig folder does not contain "Mozzilla" folder and the subdirectories.

I want to take the backup as the purpose.

I suppose this is a bug. So, could you fix it?

Thanks, G

West Virginia has a website to download old death certificates, but they wont load. There's nothing but a blank page. I'm not positive that it's a Firefox problem, as a friend of mine who uses IE cant load them either, however, she CAN load them on her Tablet. As a historian, I really need to get these records for my research, so I was wondering if someone could go to the site and see of the records appear for them to be downloaded. This is a direct link to one of the records:

link text

While this is the main page were you enter the name you are looking for: link text

If you discover anything, please let me know. Thanks!

Recently Firefox started "crashing." It would be running just fine, and then websites would just stop loading. If I clicked a link or searched for something, it would be stuck loading until I restarted Firefox. I tried restarting my computer as well, but that didn't work either, as the issue just came back within a few hours.

Sooo I went to google to search for answers. I got to a forum (https://support.mozilla.org/en-US/questions/881250) that seemed promising, and edited my network.http.max-connections value from 900 to 48, as the chosen answer suggested. I figured if it didn't work, I could always just change it back.

How wrong I was.

Not only did it not work, it prevented me from doing anything. Now when I open Firefox, nothing loads. I can see the toolbar, search bar, and my bookmarks, but the actual screen is blank. No widgets with my frequently visited sites and some news stories, no homepage, just blankness. When I enter a url or do a random search or even try to open about:config, nothing happens. It doesn't even show a loading icon.

I attempted to refresh Firefox, but it got stuck in the loading stage, which I attributed to my already breaking it somehow. So I uninstalled and reinstalled Firefox. But no dice. It's still entirely unresponsive.

Any help would be appreciated. Please keep in mind I'm largely computer illiterate!

Running Windows 10 and Firefox 102.9.0esr 64-bit. I seem to have affected the print facility so that the contents of a frame within a webpage do not print. The frame contents do show on the preview screen but then disappear when the Print button is pressed and they are not printed. The rest of the webpage is printed OK. Typically this happens to the 'Sellers Description' on an Ebay item. I have upgraded to Firefox 115.7.0esr but this has not fixed the problem. The print works fine on another machine running Windows 10 and Firefox 91.6.0esr 64-bit. Is there a way to get the full print back? Regards, LRB

For a few months, I have encountered an issue with videos playback on my browser. On most websites (including Reddit, Dailymotion, and even some videos on YouTube), whenever I scrub back a video, it will stop for about ten seconds, while the audio keeps playing.

My current extensions are: Metamask, Bionic Reader, uBlock Origin, Return Youtube Dislike, and TWP Translate Web Pages. I have tried using Troubleshooting mode, but the problem persisted, so I think it's not because of my extension.

My OS is Opensuse Tumbleweed, with Firefox version 155.0.3. I didn't have this issue with Firefox ESR on my previous Debian 11 installation. I hope someone can find a solution for this, as it is extremely troublesome switching to Chrome whenever I want to watch videos.

I am trying to print shipping labels from Amazon and a third-party web app running Firefox 103.0 64-bit.

Text prints just fine but images (barcodes, etc) that need to be scaled down do not do so causing them to be truncated on the page.

I have cleared print settings and tried two different printers to no avail. The documents/images print correctly from Chrome. I have tried using the system dialog to print but this also does not correct the issue.

Any help is greatly appreciated as I currently cannot use Firefox for the essential daily task of printing packing slip / mailing labels.

I just updated to FF 111.0. After restarting FF comes up but then nothing. After a bit of I got the option to force close it. I tried opening a Private Browser and that worked fine so I figured it was one of my add-ons. However after closing the Private Browser and trying opening normally again it worked just fine. Disable all of my add-ons and for the same issue.

Renamed my AppData/Roaming/Mozilla folder and starting as normal worked fine. What a giant pain in the <bleep> trying to set everything back up.

Performed some more science and noticed this. After setting my Mozilla folder back, starting FF, and looking at the TaskManager, There would be 3 processes, one of those after a bit of time would show in red as Not Responding (or words to that effect). Clicking the window a few times to get the force close dialog again. Trying to open FF again, it opened just fine.

So I'm tempted to blame something in the update that is causing this. Yes, I could just start with a fresh Mozilla folder and reinstall all of my add-ons and blah blah blah, but whose to say that after setting everything back up the way I had it the problem won't come back.

I have thought about rolling back to FF 110.0.1, and suppressing the update check.

OS: Windows 10 64-bit Firefox: 111.0 64-bit

Is there a memory issue with Firefox in regards to how PDF files are shown?

This happens every so often.

When I open a PDF the font is distorted and it seems to be encrypted. I have to close Firefox and reopen and then the PDF file is displayed correctly without any issue.

Thanks.

I was upgraded to 101.0 last night, now firefox only displays blank white screens. No other updates to the computer happened (windows10).

How can this be fixed? thx ,-m

Starting a few weeks ago, firefox would not load any accounts via https://login.microsoftonline.com/ one one of my Macs.

I was running the latest version 121.xx on MAC 12.7.2

Nothing would fix the site issue, so I tried re-installing and refreshing Firefox. Followed all the troubleshooting steps.

Now firefox is completely broken. Tried creating a new profile. Running in safe mode, etc.

It sometimes will load pages, but extremely slow. But generally is unusable.

Firefox works on my other macs just fine (Profile uses sync with those machines)

Safari and Chrome work perfectly fine. No malware. No ISP issues. No firewall.

Please advise a fix or I guess I will delete everything firefox related.

Hi ,

In profile folder, Check if you see a file called logins.json.corrupt. 6.If you do, rename the file to logins.json to fix it. 7.Start Firefox. The passwords should be available again.

the file logins.json become again logins.json-1.corrupt

I have this ennoying issue since some months and didn't find a way of fixing it, even by completely deleting the app and removing all remnants of profiles before re-installing it. If I leave Firefox open when I shut down my computer, most of the time (but not every time!) instead of opening the last window with its tabs, Firefox displays the KDE Plasma's or OpenSuse's splash screen (which is a lamp bulb on a black background) and no menu). If I minimize the window, and maximize it again, it displays a screenshot of my desktop!... I can't do anything but close the window and re-launch firefox, but then the history of last closed windows is gone.

I have the same version of FF and the same version of OpenSuse on two other computers and never had this issue on them.

I would be grateful to anybody who could give me some tips to solve it or even investigate!

Thanks for reading. Erik

On this page with an Atari emulator, I am unable to use its controls that use the Alt key, such as Alt+P to pause.

It works with another browser, or with a fresh profile.

I've tried disabling add-ons and trying it again, but it fails even after disabling each of them. It also doesn't even work in troubleshooting mode, and that seems kinda odd?

It may be some modified settings in my Firefox profile? Though if it is, I don't know what settings, nor how to fix it. What sorts of settings are retained even in troubleshooting mode?
