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!

Noticed geo.provider.network.url setting in about:config no longer works in firefox 102.0 ubuntu. I use it consistently so it was easy to notice that it no longer had any effect after updating.

tested both on https://maps.google.com and https://browserleaks.com/geo

Is it possible to revert to an older version without losing my data?

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.

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.

Hello, there is the note for FF 102 Release:While Bug 1771084 does not represent a specific vulnerability that was fixed, we recommend anyone rebasing patches to include it. 102 branch

Patch 1 and 2. 91 Branch: Patch 1 and 2 (Despite saying Parts 2 and 3, there is no Part 1). To clarify, so the current 102 release of FF does not 'contain any patch for that bug 1771084, and it's recommended manually to install these patches? Or they are already incorporated in the release?

Starting today, with firefox 102 (on Ubuntu 20.04), I cannot open a url using the address bar. If I enter a url and then hit Enter, it brings up my selected search engine looking for that url, not opening the url itself. This has not happened before today. Is there a way to use the address bar only for opening addresses, and use the search bar for searching?

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

I have set my privacy settings to block all third-party cookies, but it makes wading through the console annoying when working with my userscripts.

Not only do I not care as practically every site complains about it, but the warning isn't even useful in understanding what has been blocked most of the time. I just end up with a console filled with "Cookie “” has been rejected as third-party." from a bunch of random sources.

Is there some way to suppress these and only these warnings? I want to be able to actually use warnings in my scripts. As of now, I just don't display warnings and use the other logging levels.

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 have a linux debian 11 o/s with up-to-date Firefox I don’t know which version at the moment it is whatever debian repo pushes down. I have 5 profiles on this particular computer with no previous issues. I decided to create another profile to be used for some test work and when I created it I then launched it and opened a few tabs to make sure it worked then closed. I planned on copying the profile files from another profile into this one so I went to the profile folder - /home/user/.mozilla/firefox/profile.names

Once there I saw my other profiles but could not locate this one so I went back to an open browser where I had the about:profiles page open and decided to delete that new profile and start over I figured maybe I accidentally saved it to a different directory. I hit remove it and it gave me the box asking if I wanted to remove files I chose yes I then go back to - /home/user/.mozilla/firefox but folder firefox was gone with all of my profiles all that was left in .mozilla was - /home/user/.mozilla/extensions and - /home/user/.mozilla/systemextensionsdev. Both of these folders - “extensions” as well as “systemextensionsdev” are empty. I go to the local directory for each profile and the data is still there for each of the profiles - /home/user/.cache/mozilla/firefox/profile.name.

The recycle bin is empty. A system-wide search for the profiles comes up with just the ones in the .cache folder. Back at the about:profiles page any attempt to open the preexisting profile results in a prompt asking me to create a new profile. I still have the one profile open and the addons are not working correctly. I did a bookmark export on this profile and doing so generated the “firefox” folder that had disappeared plus a profile folder using the same name of this open profile - /home/user/.mozilla/firefox'profile.name - it created a profile folder for this open profile using the correct name.

Any ideas on how this happened? Can the local profiles still in .cache be used to somehow restore the full profiles?

My OS is Pop! OS. Using 'Tidal' as a web based music streaming service and I play vids on YouTube. Every time a new song or video starts, or when I skip, rewind or do anything like that, it auto resets the volume level output in my sound settings to about 75 to 80 % of the max possible level. So basically, I have to adjust each and every new song by hand, it is infuriating. I block facebooknet in Umatrix and firebaseinstallation googleapis as well as google tag manager but nothing else. That's on Tidal, similarly I do not block essential cookies on YouTube, so I don't think that is the problem. I have a hunch that the answer is somewhere in about:config. If this is intentional, then I'm giving up hope. Thank you.

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?


To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

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.

Hello,

Since recently the bookmark dialog has changed its behaviour, and to worse from my perspective. If I don't do anything for about three seconds, the dialog closes and the bookmark is saved to a place where I most likely don't want it to be saved. Is there a way to get rid of the three second time limit? Thanks!

It's not necessary to read further to answer my question. Bellow I'm going to give some criticism and express frustration about this new feature (or is it a bug?). The criticism is not directed towards the nice people here who give support to users who have problems.

I understand that developers get new ideas and want to put them into practice, but if you change an often used behaviour like this, I don't think it's user friendly to just change the behaviour without asking the user if he want's that behaviour. Personally I don't see how the automatically disappearing dialog helps me (it's very easy to click Esc if I change my mind about bookmarking a page), but I keep experiencing how it makes my browsing experience worse, as I often pause for a moment for example to think what name I'm going to give for the bookmark, or where am I going to place it.

In practice this change has wasted at least an hour of my time (to find an explanation and (in vain) a solution to fix the behaviour), made me annoyed, and based on the comments here and other places, made quite a few other people annoyed too.

Please, when you change the behaviour of Firefox in the future, before changing the behaviour for an individual user, ask him first if he even wants the change. For example show him a dialog where he is told that "we have this new feature where your familiar dialog keeps disappearing every three seconds for no reason so that you get the pleasure of invoking it again...and again...and again. If you want to have that feature, check the box on the left".

Hello. For the past few days, I am unable to access the content of some websites. For example, Reddit seem to load but the page remains blank.

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.
