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!

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.

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.

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.

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.

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?

Reproducable crash in ubuntu 20.04 from Firefox 102.0 64-bit

Steps to re-create: create a new campagin attempt to change the display image using the hover-button over the image on the page.

What happens: I click the "change image" button, it gives me the os file picker. I select the file i want and click open and the file picker goes away. The "progress" bar at the top of the image shows up, changes through several states it seems. Then all screens freeze, and the computer stops responding to all output.

Supplemental info: This started happening after an update from ubuntu 18.04 lts to 21 to 22.04 lts. So I know I was not using a flatpak before and I am now.

I've attempted to use strace to figure out what's happening at the time of the freeze I'll include a picture of that if this form does not cause my entire pc to freeze. But didn't really get any useful info from that. I tried reading dmesg at the time of the crash but so far the screen freezes before any relevent information pops up. I've not been able to find any logs about whats going in previous dmesg logs.

Troubleshooting steps: I've attempted the same procedure in firefox's safe mode. This does not seem to stop the crash. I've attempted the same procedure using chrome and this works as it should.

I run wxmaxima on ubunbtu 20.04. The help menu option calls up firefox (v 101.0.1 (64 bit)) to find the local on disk html files. However this brings up the error message:

File not found

Firefox can’t find the file at /usr/share/maxima/5.45.1/doc/html/maxima_singlepage.html#g_t_0025.

But this is a valid path with user access permissions and the file maxima_singlepage.html exists and has user read permissions.

So what is firefox doing in looking for this file?

I have used the ms windows 10 version of wxmaxima and the firefox help works perfectly.

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 am missing the everything from 'Other Bookmarks' after I imported it into the Linux computer, I can see all everything from 'Bookmarks Menu' though. The windows machine is not working anymore. But I have a saved copy of all the bookmarks from the windows 8.1 computer.

Is there a reason my import left out the Other Bookmarks but imported the Bookmarks Menu? How do get them into the linux firefox browser.

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?

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.
