Firefox supportforum

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

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

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?

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.

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.

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.

I upgraded to Ubuntu 22.04 recently. Since then Firefox 104.0.2 (64-bit) has been arbitrarily freezing; sometimes i have to restart the computer while most of the times I am able to kill the Firefox main process and restart Firefox.

The freeze occurs when i try to save a Web page; i don't see any "logic" as to which Web pages cause Firefox to freeze. It seems totally arbitrary.

I clear my downloads list everyday (sometimes more frequently than that) and clear cookies & cache everyday.

I have selected "no proxy" by default, in 'Connection Settings'.

This never happened until after i upgraded to Ubuntu 22.04.

I've browsed the support pages and don't find anything relevant to my problem. If I'm overlooking something, I apologize in advance!

I have attached a 'screen capture' image of Firefox processes just before i killed the main process.

Thanks in advance for any suggestions. Ramki

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

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?

Using Firefox version 102:

Open console tools and navigate to Network tab Right click on a POST request "Edit and Resend" is no longer an option? There is still the resend option Clicking resend allows you to edit the request, but unfortunately the "Content-Length" attribute is not automatically updated like it was with edit and resend, so all requests fail after being edited. This is because the Content-Length header indicates the size of the message body, in bytes, sent to the recipient. When you add or removes bytes in a JSON request for example, it doesn't get updated. The attribute can also not be manually set. How can I use version 102 to edit and resend requests the same way I used to?

Thank you.

I normally use Firefox desktop on my Linux computer.

Last week, I started using it on a public computer running Windows. I installed Firefox Portable and then logged/synced into my Firefox account on this Win computer. I noticed that in the Firefox Portable Windows “about:preferences” page, it says “Your browser is being managed by your organization”, which links to about:policies. In that “about:policies” page, it shows this https://i.imgur.com/JmD8nXg.png Policy Name: DisableAppUpdate Policy Value: true. Now I’m back on my Linux desktop computer and it also has this “managed by your organization” message in “about:preferences” and the same “about:policies” stuff. In other words, it appears that this policy was copied from the Windows public computer to my personal Linux computer. I don’t want that.

How can I undo this? And how can I block this sort of policy syncing?

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

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?

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

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

I open the terminal (I'm using FreeBSD) and I run: `firefox --help` and I get a lot of command line options. However there seems to be no way to simply get the user agent string. This is kind of annoying because I might want to plug the current version of my Firefox browser in some automated scripts. At the moment I need to open Firefox, then go to the console and type in: `window.navigator.userAgent` copy the string manually and paste it wherever I want to use it. It would be really nice if there could be an extra option to the `firefox` command, like: `firefox --user-agent` that prints this information in the console. Maybe there's a way, if it is it must be really hidden because I couldn't find relevant information on how to do it.

Kind regards, Lucas.

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.
