Firefox 技術支援討論區

I've tried EVERYTHING I can think of to fix this issue. When 'trying' to open a YouTube video in Firefox, I'm 'informed' that I'm offline - try reconnecting (or something like that). I'm NOT offline. Three other browsers have NO problem opening these YouTube videos; it's only Firefox. Can someone PLEASE come up with a REAL resolve to this issue? I don't want to give up on Firefox and go back to Chrome. But this issue is VERY annoying. Thanks to anyone who can provide constructive resolution(s). AL R.

a few days ago, Firefox stopped playing sounds. Any sounds. not youtube, not on Facebook. Not even porn videos. nothing. i don't remember installing any new software and Chrome plays youtrube sounds just fine. I listen on headphones and when i unjack, i still can only hear Chrome's browser play sounds. It seems like its not my comp, its the browser itself and it's only happened recently. i have yet to uninstall the browser and re-install, but i think if i use the Mozilla backup program to save my bookmarks, it will save whatever setting is causing the problem as well and re-installing will get me nowhere. anyone have any clue? i'm sure it's something simple but i cant figure it out

I have some Bookmarks on my laptop. I have some of these Bookmarks (Not all) on my tablet, plus some other Bookmarks.

If I sync them, which direction does the sync work in? Will all my Bookmarks on my laptop now appear on my tablet (Which I do not want to happen)? Will all my Bookmarks on my tablet now appear on my laptop (Which I do want)? Will I end up with two copies of most Bookmarks, because all my laptop Bookmarks are transfered to my tablet, plus all my tablet Bookmarks are transfered to my laptop?

I cannot find any explanatioin of what Sync actually does.

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

Is it possible to change Firefox's default keybinds? I don't see an option for this in Settings, nor in about:preferences or about:config. Some discussions on these forums suggest autoconfig.conf but that doesn't seem to have any options for keybinds. I found several KB articles on customizing Firefox, but none said anything about default keybinds:

KB: Customize Firefox controls, buttons and toolbars KB: Firefox advanced customization and configuration options KB: Customizing Firefox Using AutoConfig

For example, I'd like to change the keybind to open a private window from the default [Shift]+[Cmd]+P to [Shift]+[Cmd]+N. The latter is standard on most other browsers and is in my muscle memory. Is there any way to do that?

For years had bookmarks in folders showing on Bookmark Toolbar. Today they are all gone. Still in my Bookmarks on the drop down Menu, but not appearing on the Toolbar. Please help. Can't seem to drop and drag them there. Also, the Bookmarks Toolbar keeps disappearing every time I go to look at a new tab.

Firefox won't start after updating to version 123.0 on Ubuntu OS.

At the same time, no errors will appear, and there is also no specific crash report that would help understand the reason.

How to restore the previous version without losing profile data?

Hi,

I am unable to connect to mozilla website using firefox. It works fine on other browsers, but i get an "we're having trouble finding that site" error. I am able to open other sites on firefox.

This is the message I get. "Please unblock challenges.cloudflare.com to proceed." I can do nothing.

Things I've tried. Adding exceptions in the privacy settings in 2 seperate areas. Resetting Browser deafults. Turning off all vpn's and addons.

Nothing works.

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?

Hi, As far as I know, Firefox hasn't recently updated but somehow my address bar is now below the tabs. I have searched everywhere and can't find a solution. Searching shows that this has been happening repeatedly for years with people having to go as far as adding code to configure it. It has never happened to me until the change appeared randomly today. Am I missing something, or has the option completely (and pointlessly) disappeared? Please point me in the right direction to restore the position of the address bar. Thanks.
