Firefox 技術支援討論區

Starting as of today (Oct 13), the FACEBOOK screen suddenly moves when I am typing a comment. Whenever I hit SHIFT+alpha_letter at the beginning of a line OR simply hit the backspace key, the screen suddenly shifts about a page up, closer to top. This shifts the entry area where I'm typing down and off the screen. Just hitting the backspace to correct a typo causes the screen to scroll on its own. I have to scroll back down to the entry box and if I make another typo, it happens again. It is maddening!

I've restarted in troubleshoot mode and the same thing happens, so it is not an add-on. This is happening on both my Firefox Linux systems AND on a Windows 10 machine, so I don't think it is specifically OS related either. The screen however does stay put, like it is supposed to, using Chrome or Opera.

Is this a Firefox problem or is FACEBOOK messing with Firefox?

Original question:

> I want the new tabs to open next to the current tab and not at the end of my 644 tabs. Use to open next to the current tab and then I had to reset FF and now I can't get it back the way I had it. What do I need to add or change to get the behavior I want and had?

Hello! I am using the userChrome.css file to hide the nav bar (# nav-bar) and show it when hovering the tabs.

The following code works a bit, but when I open the developer tools they overlap.

# nav-bar {
   z-index: -1;
}

# navigator-toolbox: hover # nav-bar {
   z-index: 1;
   background-color: rgba (0,0,0,0.8)! important;
}

#browser {
   margin-top: -45px;
}

Any advice to achieve the expected functionality? Thank you

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

I am on arch linux with firefox version 91.0 and I recently left firefox (i think at version 89) tried out some other browsers for a while but came back to it and now it was version 91.0 and now I am noticing some lags/frame rate degrade at random times and I didn't found a relevant solution any where

I also tried h264ify as I read about the video codec youtube uses but that didn't fixed it and also tried a solution on the forum that said to disable H264 plugin and enable h264ify but that didn't worked as well

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

1. Open Firefox
2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

• pulseaudio process should only be spawned when actually playing a media that requires audio
• pulseaudio should not be the #1 CPU consuming process
• pulseaudio process should at the very least not massively use CPU when no sound is playing

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

This morning there was an Ubuntu software update and afterwards Firefox wouldn't work, it just opened and hung without ever connecting to a website. So I uninstalled, purged and reinstalled from Ubuntu Software and everything seemed ok. However, whenever I now try to save something, for instance images, the save to directory will default to /run/user/1000/docs even though I have my downloads folder selected in settings. I can change to the directory I want to save to and it will save there, but when I next save something it will again want to go to the /run/user/1000/docs folder. Further, I find that a copy of anything I save has also been saved into that folder, creating a new sub-directory to do so. I tried clear data in settings but that didn't delete those files and they are protected in file manager so I can't delete them myself. This will fill my hard drive pretty quickly as well as being really annoying having to change the save directory every time. What can I do to rectify this? I've now got version 96.0 (64 bit) installed.

System : Linux Mint 20.2 FireFox : 91.0.1 (64-bit)

Plugins/extensions "Hoxx VPN" and "SetupVPN" seems not to work anymore This is since FireFox 91.0.1 It takes a long time (about 30sec) connecting to the VPN, with no result. (no connection)

Both say something like : Result

<country> (SERVERS) 3.11.4 In some cases VPN extensions are not enough to bypass the firewall in your network. Extensions have only limited permissions on your computer and have limited capabilities.

We highly recommend to download our desktop client. It uses a very sophisticated VPN software and can bypass most of the firewalls.

Hello, how to make my vaapi work when i see youtube videos in Firefox 91.0.1? I tried change some flags, example

• media.ffmpeg.vaapi.enabled = true

• media.ffvpx.enabled = false

and it doenst work..

but my vaapi work with my brave browser (chromium 93 build)

I store all of my passwords in Firefox's "Logins & Passwords" feature. Even for things that are not online in any way. Whenever I need to create a new login & password record for something online, Firefox will automatically generate a password and give me the option to fill that into the new password and confirm new password fields. For anything that's not online I open Firefox and click the "Create New Login" button and fill in the details. I then go to a site online that generates passwords for me and fill that into the password field for the new entry.

Is there a way to get Firefox to offer a newly generated password at this point?

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
      sudo apt purge firefox // sudo apt --purge autoremove firefox
      sudo rm -rf .mozilla
      reboot
      sudo apt update
      sudo apt install firefox

      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)

3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin

I was following this article https://support.mozilla.org/en-US/kb/run-firefox-chromeos

Installed flatpak and repositories but when I try to use flatpak to install firefox I get "No remote refs found similar to ‘firefox’".

I have tried following a few other ways to get it installed, such as using sudo and using sudo su but that has not worked at all.

I followed to flatpak quick setup on Chromebook guide that is linked in the above help article and created the nested containers in crosh as well.

below is what happens if I go to flathub and copy-paste their recommended command to install firefox.

Remote ‘flathub’ found in multiple installations:

  1) system
  2) user

Which do you want to use (0 to abort)? [0-2]: 2 error: Nothing matches org.mozilla.firefox in remote flathub

Hey all,

I upgraded firefox to 89.0 (firefox for ubuntu). When playing videos it now uses RDD process instead of Web Content. The problem however comes from the resources "RDD process" uses. It is consistently at 100% usage of a CPU core and this is causing my fans to be really loud. I fixed this by changing media.rdd-process.enabled to disabled in about:config and this fixed the system resource issue but I don't think this is what is meant to happen.

As far as I know "RDD process" is meant to use the GPU. My computer has a dedicated GPU so I am at a loss as to what is going on here. Anybody who has any idea?

Thanks in advance.

Help please,

Dear Mozilla Support,

After some update (I think from 89.0.0 version of Mozilla Firefox - this version with new looks of tabs) I notice flickering on the tab when I loading website or refresh website. This looks very strange. Like I said I dindn't notice any issue with flickering on previous Mozilla Firefox versions. Only with these new versions with new look of the tabs. I didn't remember if it was 89.0.0 version or 90.0.0 version. I don't know if it is problem with the machine but I didn't notice this issue on another computer with 90.0.2 Firefox version but with Windows 10 OS. I also noticed this issue with Firefox 90.0.0.2 with Windows 7 OS on another computer so I don't know if this is problem with two computers or Firefox itself. Can you help me?

Yours faithfully, Piotr
