Firefox Support Forum

Please I just have read lots of people here with the same problem: I want to get rid of this dark mode and there's no help at all to solve this....how can this be possible? Help me please, please, please !!!!

I need developer tools, for some tasks. F12 shortcut is fine. I have ubuntu linux, CTRL+SHIFT+C is used for copy from terminal. I want copy something from firefox to terminal. Every time I press CTRL+SHIFT+C developer tools appear instead of coping text. Pressing CTRL+SHIFT+C again does not close developer tools. So need to press F12. Select text one more a press CTRL+C. Is it possible to disable CTRL+SHIFT+C shortcut? Is there any fork with this shortcut disabled?

Hello Firefox Support, I need help to upgrade the version of the security protocol that enables access to my NAS unit. Now the message;

indicates I no longer can access my page until I find the remedy to this issue. Thank you in advance for cooperation and help with is matter.

I have been using firefox on ubuntu 22 for more than a month and everything was working fine untill 4 days earlier when i first got error relating to security certificate issue and data hijacking. But i have been using same sites earlier too without any issue. Also those sites are just articles on site without any personal information. From last 2 days i am also getting redirecting issues. First site to redirect to during google search is bestbonusprize.life then if i disable adblocker it just keep redirecting. I don't have any issue accessing same site in google chrome. I just have firefox installed till 4 days earlier, but when i start getting issues i installed chrome to test if i am getting same issue but all work good in chrome. One of the main change from earlier is i was in different location using different wifi provider. It could be one of the issue but i am not sure as other people using same wifi don't have much issues. Plus things work fine in chrome. I tried using anti-malware but malwarebyte is only available for window and i don't know any thing about anti-virus and malware removal for ubuntu as never needed it. Please guide me for securing my firefox browser. Regards.

I have When you open a link, image or media in a new tab, switch to it immediately" selected, but it doesn't go there when I do select a result from DuckDuckGo or Google. I need to right click my mouse and select "Open Link in new tab". How do I make this happen?

When I join a Google Hangout and try to share my entire screen, Firefox always prompts me whether to share a window or the entire screen. I always want to share the entire screen. But when I enable the checkbox for "Remember this decision" I get this warning: Firefox can not allow permanent access to your screen.

Why does this happen? Is it because I'm on a unbuntu or is it specific to ubuntu Catalina?

Formula1.com stream does not work with message 'Firefox is installing components needed to play the audio or video on this page. Please try again later.'

Restarting browser, toggling DRM, using private window does not solve this.

Raspberry Pi B+ v2 latest OS and upgrades

Trying to install Firefox. sudo apt-get install firefox appears to work with Firefox appearing in applications list. But click on it, get busy indicator for ~10 sec, then nothing. Rpi reverts to normal idle screen awaiting input.

If I try to install again get message that already have latest verson 91.10.0esr-1-deb11u1+rpi

Help please

I wish to backup my password file and tried to follow: https://support.mozilla.org/gl/questions/1189644

I could not work it out and suspect the instructions refer to a version of Firefox I'm not using. My version is 68.12.0esr.

Thanks

Hi, Downloading files to a system directory (Linux) such as /home/me/doc/here /home/me/doc/there Have Ask me where to save files checked.

But lastDir is not a real directory I can navigate, such as /run/user/1000/doc/3dcccd48

This causes the user needs to navigate sometimes very long system directory tree for each successive file download.

In about:config I set:

 browser.download.lastDir 
 browser.download.lastDir.savePerSite	false	
 browser.open.lastDir

But every time these are obfuscated to something like: /run/user/1000/doc/3dcccd48

This introduces about 10 user interactions with mouse/keyboard for each file I download in succession.

How do I get FF to stop obfuscating real system directories for "lastDir"

Really really appreciate the help :)

Evening, all.

It's very rare I ask for help on ANY fora, if I'm honest. I can almost always sort out my own issues, especially with browsers. However, this one has stumped me.

I've noticed that, on any website where user interaction requires use of a microphone, the Linux build of Firefox only ever offers "source_default_name" for choice of microphone. Well, OK; I can see this being fine for the vast majority of folks who use a laptop; the built-in microphone WILL be the "default" microphone, no questions.

My question is this; what do those of us running desktop PCs do about microphone selection, hmm? A desktop PC doesn't HAVE a "built-in, default microphone", does it? By their very nature, any microphone you're going to use with a desktop is going to be an externally plugged-in device. I have three of these; a USB microphone.....a wireless headset, and the twin stereo mikes on a Logitech c920 webcam.

Do I get anything resembling a drop-down list to choose what I want to use? Uh-uh. Firefox - apparently! - doesn't "see" any of them. Not individually. All I ever see is "source_default_name".....

Grrrr...!!

C'mon, guys! Frankly, this is about as much use as a chocolate teapot. Linux, to the best of my knowledge - unlike Windoze - doesn't make 'global' device settings, which every application then uses. It's always been far more fine-grained than that, allowing individual device use on a per-app basis. But that only works if the 'app' in question allows those choices to be made.

Any Chromium-based "clone" - and I use several of these, as I package portable versions for the Puppy Linux community - will give a full drop-down list of every available device it can find. Why can't the Linux builds of Firefox do the same?

I shall be interested to see what, if any, replies I get to this question. It's been bugging me for years...!

Mike.

I'm clicking on a list of links on a page, and the download-panel keeps popping up. This blocks the view of the page that I'm clicking on and I lose my position on the page as I'm clicking.

I like seeing the download-panel, so I don't want to turn it off. I'd just like it to show only the last clicked-on entry, not the last 10 or however many it's showing, which seems to include completed downloads.

I can see that it has a hard limit on how many entries it shows. Is there a way for me to adjust that limit?

I can only install Firefox by downloading from the google play store. When I do that it installs something but it is not a real version of Firefox. If I download firefox from Firefox web site I get it to install but Google will not list it under browser. I have to use it by clicking on the Firefox icon which is totally separate from Google.This is aggravating. Is there a fix to make it part of Google's browsers? I am using a Samsung Notebook that is Goggle driven. I have the same issue on my desktop computer. Google will not let real firefox as part of Google. Thank you .My email address associated with Firefox is no longer working.

Firefox was working fine yesterday. But all of a sudden while playing a youtube video it started being choppy. It drops frames, scrolling and video playback are choppy and laggy, there is lag on button inputs, the system is choppy and laggy too while firefox is open, especially when video is playing. I checked the CPU and GPU usage and I can't see any spikes. I have tried refreshing firefox but that did not fix the problem.

OS is manjaro linux (gnome version) latest. Firefox is also at the latest version.

On my linux laptop I have a lot of saved userids in Firefox that do not have the password saved - which is exactly what I want for some sites (like bank sites and credit card sites) that I want it easy for me to log into but impossible for anybody else. On my Windows desktop now, however (apparently I inadvertently deleted my saved logins), I can't seem to figure out how to duplicate this functionality again, i.e., save the userids but not the passwords. Firefox seems to want to save both, or neither. How do I get my desktop to do exactly what my laptop is doing, save the userid but not the password? Thanks.

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

I run firefox from the command line in a terminal, and recently I have been seeing this set of messages in the term when I load various webpages:

Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index3/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/present Sandbox: attempt to open unexpected file /sys/devices/system/cpu Sandbox: unexpected multiple open of file /proc/cpuinfo

Mostly, there doesn't seem to be any loss of function related to this message. However, I have one anecdotal example of a forum website I have used in the past freezing on a blank screen at the same time these messages pop up in the term.

I can find no match for this particular message on the entire open internet. There is one near-match on bugzilla bug # Bug 1718493, but that is solved and done.

Any thoughts appreciated, thanks!

Hello good people, This is rather a request for advice than an issue report. I' ve learned about the facebook container add-on and wanted to know if there is a need for it if someone was making sure to exclusively open facebook.com in its own profile. Say you set up a profile(from about:profiles) namely "BIg Brothers" for notorious trackers like google, facebook , twitter etc so they can perpetually track each other with simple rules to observe like : - Never open an external(shared) link - Never access any other website through that profile.

Is there a particular feature the add-on is bringing up that the native interface is missing ? The other reason is add-ons are great but they tend to bloat the system impeding the browsing experience. I am the kind of guy who opens 7 concurrent tabs each running heavy js code so the lighter the better.

Thank you in advance,

Dom

When I download a file (eg. a debian binary package) and click to open it from Firefox' download tab, it doesn't use the system default application (here, Ark instead of QApt)

I do not use the majority of keyboard controls in Firefox-- only Ctrl+F. Lately, I've noticed that using Ctrl+I in editor windows also pops up the Page Info window, which I have never used on purpose and am perfectly comfortable accessing via Firefox's menubar.

I have been searching for over an hour, and every Firefox add-on that I can find to fix this problem has been removed.

Ideally, I would like to be able to configure all of my keyboard shortcuts, but practically I will settle for being able to disable Ctrl-B, Ctrl-I, and Ctrl-U.
