Firefox 技術支援討論區

I've been using Firefox for many years without a problem and have always liked it, but I've recently starting encountering a problem where Firefox consistently crashes after closing. After I close Firefox, the Windows Task Manager shows it still in memory. After a couple of minutes, the Mozilla Crash Reporter screen pops up informing me that Firefox had a problem and crashed, with an option to restart Firefox or Quit. I tried refreshing Firefox, which was a challenge because of the problem of hanging in memory after closing, but it did not resolve the problem. I also tried uninstalling it, then deleting the Mozilla folders and clearing out any references to Firefox in the Windows registry, and reinstalling it. I haven't installed any extensions yet; but sadly, I continue to encounter the problem. Any ideas about how to resolve the problem?

I should mention that I had bought a new SSD for my computer and migrated everything over from the old SSD to the new one. The problem with Firefox began after the migration. Everything else that was installed there works without a problem. I would be surprised if this is related to the issue considering I've reinstall Firefox.

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'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

xdg-desktop-portal xdg-desktop-portal-gtk

Hello, I just installed windows 10 on my nephews computer. I installed firefox so I don't have to use edge, but firefox won't start. It just flashes. I have tried re-installing firefox, deleted all mozilla and firefox files and folders and clean installed firefox, even reinstalled windows. Troubleshoot mode don't work, it just flashes too. I checked for Crash Reports, but there are none. The only time it works is when windows is in safe mode, I even upgraded to computer to windows 11 hoping that it would fix what ever is going on. But it didn't. I honestly have no idea what to do next. Firefox has worked on that computer before. Everything else works fine, it's just firefox that won't work. If anyone has any ideas, please let me know.

Hope someone can help.

When I use full screen for some websites, it darkens after about 2 - 5 seconds and my cursor also becomes harder to move. This only started to happen recently.

It is not my computer settings, I've tested this in Safari and it works normally. This makes videos unwatchable. It is like a dark screen suddenly appears over the video and only comes off if i move the cursor. It happens with netflix and prime but not youtube, udemy.

I used to be able to scroll to the bottom of my Youtube subscription list, to see the very first posted videos of all of my subscriptions, going back to the first days of Youtube in 2005. Granted, not all of the videos would show up, and I don't know if that is a Youtube problem or a Firefox problem, but most of the videos would be there. Now, after going back less than a year in the archive, the scrolling just kind of peters out. Firefox becomes unresponsive to any key press or mouse click, and all I can do is quit the program. What has changed? Has Firefox gotten even worse at memory management? it was always a total pig with memory, but has it reached the point where it just plain malfunctions and can't recover? If that is the case, then Firefox devs had better get their spit together and work on optimization. I really don't want to have to start using Edge, thank you, no. I only use Edge to view PDFs.

I am using a Dell Inspiron 3847 with the standard keyboard which came the system years ago

Recently, when viewing a large online page, when I try to scroll down, the scroll doesn't start until about two seconds after I press my scroll key (which is the lower-middle key of the 4 keys between my right-hand "Ctrl" key and the "0" of the 10-key keyboard at the far right of the keyboard).

This delay started happening a few weeks ago. I do not know whether something I did caused it.

How can I scroll my view starting immediately, rather than having to wait two seconds for it to start?

WOW what's with F/F Worked fine yesterday, last week, last month, haven't changed anything. Today I opened it up and tried a Google search (www.google.com and I live in Canada) I get this id Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection. www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely.

So then I try and connect to my email server https://webmail.shaw.ca/ Hit login shows this in the address bar https://webmail.shaw.ca/#1 and it just sits there. . . . . . nothing, totally useless Did a full antivirus scan with Defender and then Trend House call, nothing Went to my wife's laptop that is identical and everything works fine. Loads fine So I uninstalled Firefox reinstalled and same problem, tried Refresh, same problem. What gives, I'm being forced to use Chrome for now, if I can't get this fixed firefox is down the road

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 recently got a new PC, and every time I open up Firefox it instantly closes. I have tried downloading it on the Microsoft Store, it seems to work fine for 5 minutes and then it happens again.

Hi,

I am running Firefox 108.0 on Ubuntu 20.04.5 and videos on Reddit don't play, they just buffer (?). Youtube works fine. I've tried the suggestions on this page: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#search but nothing seems to work.

Thanks

I have been using firefox for more than 4 years now. But from about a year, i m facing the issue with the Sudden High CPU usage in Windows task manager.

The task manager has 2 different firefox processes. One being actual instance i am running. and the 2nd being the automatically opened in background.

i have figured out whenever i have active internet connection and my system is on charging the 2nd task automatically starts in background and uses upto 80% of cpu usage. Ending the 2nd task form task manager doesn't affect anything. only the cpu usage drops. Also Closing my firefox instance does nothing to that 2nd task.

I have tried lot of solutions i found on community. Nothing seems to help. problem still persist. I even posted comments on ongoing threads. but no reply from anywhere.

this is the last time i m trying. if i get a solution its good. otherwise i am going to shift to edge. I have no other choice.

Screenshots from multiple dates are attached.

I've posted this problem before and did receive replies attempting to help. Unfortunately, the problem has continued for a long time (I think at least a year). I frequently can't access websites (e.g. Yahoo Mail) using Firefox but can using Edge or Brave. With Firefox, I get the following error message:

"Secure Connection Failed An error occurred during a connection to login.yahoo.com. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

I had hoped that the problem would be solved by a Firefox update but that has not happened.

I also regularly get the message "No Internet Connection" while using Firefox but, when I use Edge or Brave while the error message is displayed, there is Internet connection.

I'm using the latest versions of Firefox and Windows 10 Pro.

I've used Firefox for many years and really don't want to have to switch to, say, Brave.

Ed

I have a blog hosted on Render. The base URL provided by them is https://parker-codes.onrender.com. This URL works perfectly, in all browsers.

I purchased a domain from Google and then linked a CNAME record to the Render one: https://blog.parker-codes.dev. This URL works in many browsers except for Firefox Mobile (on Android). I receive the error "Address not found. The browser could not find the host server for the provided address."

- I flushed the DNS cache and checked that it propagated across the globe. I used nslookup to verify the domain resolution. - I tested in various other browsers on desktop (Safari, Chrome, Firefox) and mobile (Chrome) and they all work. - I turned off mobile extensions. I also tried in a private window. Still no luck. - I reached out to Google support. They don't see any domain or DNS issues on their end.

From all of this, it appears that the Firefox mobile browser has a bug that can't load the site for some reason. It can't properly resolve the host even though many other browsers can.

As title suggests, since the past few months, my Firefox has been having problems with images. On some websites and in some occasions, images will appear as artifacts or broken/glitched. This also happens on some websites where I upload images from my PC, which also displays those uploaded images as artifacts/glitched. They are indeed broken images files if I'm the person uploading them, not just thumbnails, because other people also see the uploaded pictures as broken on their side as well when I asked. Websites like Google Photo is also broken as well.

Disabling hardware acceleration doesn't help. I suspect it has to do with something with my own Windows or something like that, not just Firefox.

See some examples below:

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

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

Someone knows why?

When I go to https://squareup.com/login the entry fields do not appear in Firefox. It's impossible for me to access my Square account through Firefox currently, which I use for client invoicing. I have no trouble logging in through Chrome. Screenshot attached.

I have Privacy Badger and AdBlock installed for both browsers. I tried disabling them for Firefox just to see if that was the issue, but it made no difference. I am using an iMac running macOS Catalina version 10.15.7. My Firefox Browser is version 97.0.1, and currently shows that it's up to date. My Chrome browser is version 98.0.4758.109, also up to date.

I have a problem when I switching tabs it looks weird I can't explain. I will attach a video proof.
