Firefox 技術支援討論區

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

On our online application we are facing with some strange behavior for a small percentage of our firefox users (<1%).

When doing oauth2 authorization, after generation of the authentication token we redirect to another platform but we are detecting that for a small percentage of Firefox the cookie (my_auth_cookie) with the auth token is not present.

GET: https://www.mywebsite.com/application/login Response:

new location https://www.mywebsite.com/otherapplication/redirect

set-cookie: my_auth_cookie expires=Mon, 04 Dec 2023 13:49:15 GMT; domain=.mywebsite.com; path=/; secure; samesite=lax; httponly

      2. GET https://www.mywebsite.com/otherapplication/redirect

          Set-cookie: mycookie: value

          Host: www.mywebsite.com

In cookie tab I see my_auth_cookie (value: xxxx, domain: .mywebsite.com, expires: Mon, 04 Dec 2023 13:49:15 GMT, httponly: checked, secure: checked,SameSite: Lax, partitionkey: empty, Priority: medium

I’ve tried to replicate but without success (with multiple extensions, including multi-account containers), with multiple configurations of Total Cookie Protection.

Again, this only seems to be happening to a very limited number of firefox users but for these, it happens 100% of the time. We see it occurring for versions 119 and 120 but now and then for older versions.

Feedback reports no extensions&addons.

Any ideas on what we could be dealing with? Any help would be greatly appreciated.

I have been having with YouTube for a couple of days. It asks to turn off ad blockers. I have done so and it still requests to turn ad blockers and still won't allow viewing. YouTube works on other browsers.

I am sure YouTube is playing games but can you help?

Hi - I just reset my PC and trying to restore Firefox. I saved the default release folder (qejikze4.default-release-1669319412153) which contains the latest bookmarks in the "bookmarkbackups" folder. I tried to just replace the bookmark file in the new install (how I previously transfered them), but I can't find the files in the latest V.120 version. Any suggestions on how I can do it?

Thanks

After years of shopping online with Tesco using Firefox suddenly I can no longer log in to Tesco.com. Just get 'Access Denied. You do not have permission to access------etc' I am sure that this happened after the last update of Firefox ! Tesco say its not their problem and the problem is with my Firefox browser. Please advise.

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

I was working in Firefox, everything was working fine and all of a sudden, by tabs began to crash. I only had 2 tabs open. I opened Firefox in Troubleshoot Mode and still, the tabs crashed. I opened More Troubleshooting Information and tried to Refresh Firefox, but it appeared nothing happened.

I do not want to lose the Bookmarks I have saved!!

Thanks guys for screwing up my day with your latest update. I used to be able to download a .pdf and opening it in my ,pdf reader. I NEED to do this for tax reconciliation purposes. Now your crappy program has decided to open .pdfs in itself and I cant get a downloaded copy any more. What the hell was the programmer thinking? Yes I have gone to Applications and checked that it is set to my .pdf reader. Please fix this before I get fined by the tax office.

I have been playing gin rummy plus on my windows 10 pc in my firefox browser with no problem until a few minutes ago when I tried to sign in to the game again. I got this message: Your browser does not support WebGL. The game works fine on my laptop using the same browser. Can anyone tell me how to fix this problem?

When I try to login to the Tesco website I get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server.

Reference #18.26cc19b8.1700669440.3c27026b

I have cleared History plus cookiies and site data and cached web content

But I'm still unable yo login to this site.

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

Upto Firefox v115 this website working fine. after update this website table display right side end. not in position. checked in other browser. working fine in chrome. what to do?. need solution. thank you.
