Firefox 技術支援討論區

I was trying to troubleshoot a black screen of death issue with Windows10 that first started appearing after Firefox adopted the new Private Browsing icon. In the process of doing so, I tried every combination of Firefox settings imaginable. Nothing worked as far as Asus, Windows, or Firefox settings, rolling back/ updating various drivers, etc. So, I decided to refresh Firefox and when that did not work, I decided to uninstall and reinstall Firefox. I'm not sure if that worked as far as the original black screen of death issue is concerned because now Firefox no longer remembers my cookies and site data allowed exceptions (my only exceptions were my bank websites, which worked as expected until the uninstall/reinstall). I've tried selecting always use private browsing and always delete cookies and site data when Firefox is closed (my previous settings), but every time I close Firefox and return those three exceptions are missing. Any ideas would be most welcome. BTW, does anyone know how to use that folder Firefox puts on the home screen labeled "Old Firefox Data" because I was expecting there to be a .exe file to click on to reload all the previous settings in one fell swoop.

I've asked this before with no help but I'll try again, why can't I get my email registered as safe to come in as safe senders inbox instead of in my junk mail. I've asked before with no response and don't believe there will be one this time either but one never knows. All I can do is try. Terry Penton

Long time Firefox user. Had automatic update to version 121.0 on 12/19. Shut down that night. Next morning (12/20) Firefox opened as if it was a totally new installation - no bookmarks, extensions, etc. Downloaded 121.0 64 bit version; uninstalled Firefox; reinstalled it with downloaded version - same issue. Replaced profile with backup copy from 12/17. Firefox started properly with all bookmarks, extensions and other settings.

Shut down on 12/20. When computer was started this morning (12/21) and Firefox opened - same issue - presented with brand new never before opened Firefox. Shut down Firefox, copied over 12/17 profile, restarted and all bookmarks, etc. were there. Restarted Firefox using about:restartrequired and everything was still as expected.

Windows 10 is up-to-date. No updates found for extensions.

Thoughts on what might be corrupting the profile or what steps I can take? I have 25 enabled extensions. Since a restart didn't revert me to the brand new never opened presentation, activating them one at a time doesn't seem to be a worthwhile approach.

Hello

Since several year I am dealing with browser problems. There are insulting adds appearing on the screen, there are strange network problems (I have to confirm several times that I am being human and not a bot (picture 1)), When I open certain websites there is nothing at all displayed (picture 2). Or even some variables are changed (through DOM ?). Here is an example, I was looking for a new flat at homegate.ch. I have set the rent limit to 1400 .-, and hit the search button. The result which was displayed is this (picture 3). I get flat results with a rent of 1790.- or even 1950.-. But actually I know those flats have a rent less than 1400.-. I found out, that there is a factor of lets say 1.45. If you divide the rent of the search results through 1.45, you get the real rent, this is true for all search results. My firefox settings are very security focused (HTTPS-only enabled, DNS over HTTPS, block cross site cookies,...), I am using a vpn client to connect to the internet. I guess the problem has something to do with code injection, XSS attack through JavaScript. But can t tell how, I guess cookies or session Token are involved in this attack. Can you please give me an advice, how to solve this annoying problem? Thanks in Advance

kind regards Stefan

Hello, Ive recently switched my primary browser from opera GX, to Mozilla Firefox. Since then I've adjusted the settings to my liking, one of which was the search engine. I chose google chrome, and it works when I open a new tab, However, When I open a new window of firefox, it always opens Bing. This is a small problem, yes, but its simple issues like this that dissuade me from wanting to use firefox at all, I would like to solve this issue, but Ive searched for answers, and there aren't any. If you help me fix this, I will keep firefox. Otherwise, I'll chose a browser that gives me the amount of control that I want. I've also attached a photo of the startup screen of firefox.

Since installing Avast Plus I can't sign on to some accounts to pay my bills, such as Rocket Mortgage and Synchrony. I have to go to Microsoft Edge in order to pay these bills.

The fcitx input method works everywhere on my computer except Firefox. I've added the following to my etc/environment file, which is the main suggestion I found online: GTK_IM_MODULE=fcitx QT_IM_MODULE=fcitx XMODIFIERS=@im=fcitx But it still doesn't work. My operating system is KDE neon 5.27.

I read this article on enabling/disabling hardware acceleration and I am missing the checkbox to toggle it. I am wondering if this is a firefox bug or if something about my hardware setup is unsupported. I'm using a 1080ti running on the most recent drivers, 546.33. Windows 10 Education version 22H2

First of all, an important thing to note is that this is happening on only my school laptop, and not my pc. This problem occurs on all school laptops that have Firefox installed. The reason I, and some others want to use Firefox is simply to get an ad-blocker as extensions are blocked on the default browsers (chrome and edge).

Anyway, the issue is as such: One moment, I will be browsing normally, and then the next, a page will stop loading or refuse to load any new content. It is just like there is no internet going to Firefox, despite the laptop having internet connection as seen in other programs. The way I fix this is by opening edge, waiting for it to start, and then closing edge. Firefox then has internet connectivity again and will work perfectly fine for another few minutes, before having to do it again.

I really have no idea why this is happening, and especially why it is fixed by opening and closing another browser. Obviously this is caused by some administrative program on the computer, but by the way that I can temporarily fix it, I would assume that there is a more permanent solution. The admin programs on the computer are GlobalProtect (VPN), Sophos Endpoint Agent (Security), and Teamviewer (probably not relevant).

As this is for a student, doing something that is against the school rules, it is absolutely necessary that this gets fixed as soon as possible. I simply cannot live with these default browsers with ads. /s

Hi, I have a lot of bookmarks that are specifically made to always open in a specific container.

After updating to 121 I'm always asked if I want to open the URL in a container.

How can I get rid of the question and just always assume "Yes"?

Thanks, Henrik

Hello,

I had a Firefox update last night and I now have version 121. I usually look at a French site so I click on the translate symbol on the toolbar - fine. But this no longer works - the "en" appears but the page is still in French. If I click on Menu then Translate....... just the same. This has only just happened so must be a problem with the new update?

TIA

Just recently, within the last two weeks (today is 12/22/23) Firefox it taking a long time to start. Firefox version is 121.0 (64 Bit) Windows 11 Home Ver: 22H2, OS Build 22621.2861 This is a reasonably new Acer Nitro PC (August 2023) with a solid state drive.

When I double click the Firefox Icon a large white box opens on my PC and remains that way for 10-15 seconds, then the white box fills-in with the Firefox screen. Once opened, Firefox works perfectly.

I tried the troubleshooter and Firefox starts instantly, as it did previously. I have no Extensions, Themes, or Plugins. I even disabled: OpenH264 Video Codec and Widevine Content Decryption Module. I tried Google and DuckDuck as the Search engine with no difference.

Any suggestions?

Thanks for your help.

I updated FF build from 120.0.1 to 121.0, then sound disappeared from all websites!!! and I checked my laptop the sound is working in other apps! now I watch YouTube like Charlie Chaplin. This issue happens in a new profile, as I created another one to see if it's a profile related problem, Thank you.

I have freshly install Manjaro system. On there I installed the Flatpak of Firefox. When I try to login into my Mozilla account for sync it doesn't load. See the screenshot. On my other computer it works without an issue. What can I try?

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

Hi All - I got a laugh out of the subject of this post, however it reads right. I have "Always ask where to save files" enabled. In the "About:Config" it does show Documents as the last folder. So oddly... lets say I download 3 files... The first 2 it will show Documents in the save dialog box and all I have to do is click save. Then the 3rd file it will default to dowloads for some reason. Ya I can just click Documents and click save, but that is irksome. Sometimes it will default to downloads for 10 save file attempts and sometimes it will just default to Documents 10 times in a row. Ultimately I don't want to have to check folder location each time. I will often "lose a file" and then remember I have to double check downloads, and sure enough it is there (because I forgot to double check, I just clicked save). I realize this is not the end of the world, but there does not seem to be any legit reason that I have found, that FF does this. Shouldn't it just do as it says it will do and the default location that pops up is the last location I saved to? Note this has been like this for years (I'm just now finally saying ENOUGH! :D )

Thanks!
