Firefox 社群討論區

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?

In an organization that already implements Mozilla Group Policy Templates to enforce various features and settings, how do they set up the Group Policy to disable this new VPN feature organization-wide?

I've checked the existing Group Policy template documentation and can not find any reference to this feature.

I want to migrate everything from windows to linux, i've already synchronised browsers on both systems, but settings on linux didn't get overrided.

How can i make browser on linux exactly the same as on windows (including settingd)?

When I try to run firefox 141.0 (Linux x64) I get:

libxul.so: undefined symbol: gdk_wayland_device_get_wl_seat Couldn't load XPCOM.

Is there a way to fix this?

I'm using Slackware 14.2.

"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?

Mint 147.0.4 64 bit I click on a pdf, it opens in qpdfview. It also saves in wherever my default save folder is. I later have to go remove all these junk PDFs from Downloads or wherever because I either didn't want them or saved them elsewhere.

Please stop "helping me". I do not want to be "helped". How can I stop this auto-save """feature"""?

I think this started back in 98.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

After connecting and signing in to Mozilla Connect, it seems impossible to actually log out. There is a log out option in the dropdown menu, but it doesn't work. After "logging out", when going back to the site one is automatically logged back in. This is true even after clearing all mozilla.org cookies, and closing the browser. If a different browser is used, first time access to the Mozilla Connect site requires username/email and password, but after the first access, the alternate browser is also perpetually logged in.

1. What mechanism is being used to identify me as the user after cookies are cleared ?

2. How does this fit in with Mozilla's claims to respecting user privacy ?

3. How do a log out of the Mozilla Connect site ?

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

Media resource could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<62>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: Unknown error occurred

So I just switched OS on my desktop, and had to log into Firefox all over again for the first time in a bit, and it turns out that for some reason my saved passwords arent synchronising with my whats saved on my phone? In the past my experience have been that if I ask firefox to save my password on one device it remembers it on all my devices. Is this not the case? Is there something I need to do to manually synchronise?

I actively use keywords to search from the address bar, mainly g for google, gs for google scholar and w for wikipedia. Until a recent update (until last week, I think), pressing ctrl + L to go to the address bar would select all the text in the address bar, including the keyword, such that if I had made a google search by typing g and some query, I could immediately do a wikipedia search by typing w and some query.

Now, with an updated firefox (141.0.3, on xubuntu 24.04), the search engine from the previous search remains when I press ctrl + L, so I have to type backspace(s) to remove the search engine keyword, before typing a new keyword.

Is it possible to get the old behaviour back?

When I go to see a firefox bug such as the following, https://www.mozilla.org/en-US/security/advisories/mfsa2026-10/

There appears to be more details in https://bugzilla.mozilla.org/show_bug.cgi?id=2014390 located at the bottom. When I try to view the details it asks me to log in. I do not see any reason I should have to log in to view the issue as I only intend to view the bug. Why does it require a login ?

I have a fresh installation of xubuntu 24.04, with firefox 135.0. Middle clicking on links now does nothing, whereas earlier it opened the link in a new tab. browser.tabs.opentabfor.middleclick is set to true.

I've found out that you can create custom prompts for the AI sidebar with the configuration `browser.ml.chat.prompts.*`. Usually, this is done with the selection text. However, I'd like to pass the URL instead. I could use `%url%`, but that does not include parameters after `?` and hence does not work for Youtube.

Is there any variable that I can use to pass the full URL including parameters of the URL?
