Firefox 技術支援討論區

The title describes the problem I'm facing. I don't really use other sites that have videos other than Youtube. But I notice that the videos freeze quite often and audio just continues to play. The videos then unfreeze and skip multiple frames. I've noticed clearing browser cache seems to help but it doesn't help for longer than a 2 min video at best. At worst, it doesn't affect it at all.

Hello, In old versions of Firefox picture-in-picture mode was "always on top" by default, now "always on top" mus to be enabled every time I pop-out every video. Is there any solution to make picture-in-picture mode "always on top" by default?

Since about one year I am unable to use Japanese input only in Firefox. When I try to switch with fcitx and control+space, nothing happens. However, fcitx-mocz works everywhere else on my computer (i.e. terminal, thunderbird, other browsers, etc.). Furthermore, I uninstalled fcitx and everything associated with it and reinstalled it according to this thread: https://support.mozilla.org/en-US/questions/1367181 (just with mocz for Japanese). This also didn't change anything. Any help is appreciated! My system: Operating System: Linux Mint 20.3 Kernel: Linux 5.15.0-91-generic Architecture: x86-64 fcitx version: 4.2.9.7 Mozilla Firefox 121.0

can anyone of you test chat open ai com with linux 32 bits?

for more than 5-7 months its been unusable. it completely freeze. I recently reported this to open ai devs and they tried to do something. Now page responds is in 20-60 seconds range.

means, I open website, i wait 20-60 seconds to load. I ask chat gpt something, i wait 20-60 to actually type my messsage (for my message to be printed after I hit enter). then i refresh page (because nothing moves), wait 20-60 secs to load page and I see the reply.

and yes, each time I was always trying to do with latest version of browser. and I also tried it on a new browser without any extension.

I have a video, I can only share it private with firefox devs if helps.

the reason I didn't reported this last year, was because I got extremely disappointed and unhappy.

it initially started by showing that button-bar at the top, telling that page load slow and to [stop]. by the next month it became worst than 2000's dialup internet, so I stopped using it

A few days ago Ubuntu (22.04 LTS) showed me a message saying I can upgrade my OS (or something along those lines). I click on agree (any button that would let me proceed) and the upgrade took place (without restarting). Along with the upgrade Firefox was also updated to its latest version at the time (119.0). Since then, videos on Twitter play but without sound. On some other websites also none of the videos play. On YouTube, Firefox shows me a message saying "To play video, you may need to install the required video codecs" but the videos play fine; I haven't tried other websites but I assume all would have some issues. Google Chrome however doesn't have this issue and all videos play without any issues.

Note that I have not restarted my computer since the upgrade. I doubt this could be an issue but please let me know if you think this could be the issue.

I did the followings and restarted Firefox but none have worked so far for Twitter and some other random websites that I come across, but they resolved the issue for YouTube and now YouTube videos play, although I still get that codec message at the top of the tab:

sudo apt-get install ffmpeg sudo apt install ubuntu-restricted-extras sudo apt install libavcodec-extra

Someone told me this is because the default Firefox on Ubuntu 22 comes as a snap package and I should install the APT package manually instead so that it works. I prefer not to do this because I have lots of tabs open and have manually changed lots of the settings (including in about:config) that I want to preserve. I would also like to preserve the history of visited websites and keep the current cookies (don't really want to keep entering username/password on the same websites again). So the best way for me is to fix the issue for the default Firefox on Ubuntu 22.

Could you help me figure out what I should do to fix this issue?

Hello, I'm trying to use https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/dom/openOrClosedShadowRoot functionality in an extension but the element.openOrClosedShadowRoot always returns null.

Also is there a place in Firefox Devtools console (similar to the Chrome Devtools dropdown) to switch the context from the user console to the extension console so we can try extension only APIs?

Thanks.

Hello, after updating Firefox to v.119 a couple of issues have developed that I can’t seem to resolve.

First of all the Firefox logo has disappeared from my home page. To show what I mean here are some screenshots: The 1st one shows what I see when I open the browser as normal - as can be seen I have several extensions normally in use so the 2nd image shows Firefox opened in ‘Troubleshoot’ mode.

Both these two were taken with the Privacy & Security settings set to ’Strict‘, the 3rd image shows ‘Troubleshoot ’mode with Privacy & Security set to ‘Standard’. ~~~ Now onto the subject of fonts; I’ve done some searching around and even with the Privacy & Security settings customized to ignore fingerprinting, Firefox still ignores my font-setting preference, which is FreeSerif, usually at 14 or 16pt size. Despite me unchecking the setting to allow websites to use their own fonts I cannot get any page to load using my preferred font. This causes me problems as I suffer from a particular type of astigmatism which makes san-serif fonts difficult to read.

Thanks in advance for any help offered.

Hello, I've got a reproduction issue on France TV live programs which I watch through nordvpn. The picture keeps "jumping" fast up and down in a very bothering way. This doesn't happen when the video is NOT live. I run the latest version of LINUX MINT. What can I do to fix it? The only way I found to stop the issue is to take down the resolution of the live video to its minimum which gives me a disastrous picture but stops the "jumping". I guess you might say there is something wrong with my GPU. The point is that my PC is brand new with an AMD 5600G, new MB, 16Gb of RAM and 500w of PSU. BUT more than anything I have to say that everything WORKS FINE with CHROME. I like FIREFOX I have been using it literally for decades now. (I'm 75). Is there a solution? Looking forward to hearing from you. Thanks in advance. François.

Dear Friends,

Trust all is well...

PLEEZE put an end to this mystery. Can you BLOCK YOUTUBE ADS or not? If so, how is that accomplished.

Many of the extension are not safe even dangerous to use.

Thank You!

Best, Ralph

OS: Ubuntu 23.10 Firefox version: 119.0 Mozilla Firefox Snap for Ubuntu

I have DNS over HTTPS enabled and set to Default Protection in Firefox.

According to the following article (https://support.mozilla.org/en-US/kb/dns-over-https?as=u&utm_source=inproduct#w_why-would-a-network-tell-firefox-not-to-use-secure-dns) DNS over HTTPS should automatically switch to "Not Active" when connected to a VPN.

I am using the NordVPN CLI for linux and have found that when I connect to the VPN, Firefox DNS over HTTPS stays active and does not switch to "Not Active" like it is supposed to.

Does anyone know why this might be happening?

Hello, I did something stupid. I was trying to set up the dark/light theme via cli, and I asked openai about it.

It suggested this command:

echo 'user_pref("lightweightThemes.selectedThemeID", "firefox-compact-light@mozilla.org");' | jq -s '.[0]' > ~/.mozilla/firefox/*.default-release/prefs.js

Which resulted in the following error:

jq: parse error: Invalid numeric literal at line 1, column 11

When I opened mozilla, my profile was reset, and websites won't load (except this one!). They just hang there loading forever. My internet is fine, chromium works perfectly.

So how do I fix this and is there a way I can recover my profile? (Yes I know I should've made backups)

When I open Firefox, the wrong town name is always there with temperature. Can't Firefox remember my town name? I'm getting a little upset that so simple a problem can't be fixed automatically. Sincerely Bob

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

Steps to reproduce: 1. Open youtube 2. Open any video 3. Hit back and navigate to youtube main page 4. Press media key play/pause on keyboard

Expected result: nothing happens Actual result: the sound from the video continues on the tab with youtube main page, the tab has "PLAYING" on it

I have never maximized a Firefox window and I never will. After the latest update, all new windows, whether they are opened from another page via right-click or directly from the toolbar icon, open in a maximized view. I do not want this. Is there a way to prevent your program from inserting itself directly on top of everything else I'm working on? Have I accidentally changed a setting I cannot find again? I'd like to know if I need to find a new browser.

hi Edge is 2x faster then Firefox using Onshape 3D cad cad program Firefox picks another driver GTX 980/PCIe/SSE2 Edge use Gforce RTX 3060 PCIe SSe2 How can I make Firefox use the same driver as Edge

So I have two different accounts for one website. However one of them I use very rarely, maybe once in 2-3 months the other one i use almost daily. Therefore I have saved both logins in Firefox and I can see them in my passwords.

The problem is that whenever I try to access the website, Firefox auto-fills the "second" account, the one i only use rarely. What this means is that instead of me being able to just press login i have to delete the username filled in by Firefox and select the other one. So what i would like to do is to maybe tell Mozilla that I want it to use the other account for auto-fill.
