Hi, I have a weird problem, I have 3 systems on my device: windows(10), ubuntu and Arch lately when i was configuring Firefox on fresh arch install I was annoyed that I needed to re-login to every single s...t again. So I thought "Why can I just share the same FF profile between systems" Long story short it didn't work on Arch. I was forced to compile FF from source and now it works... but when I'm logged in on Ubuntu and trying to launch FF from GNU I always see this error. it's working when i point out to profile from the command line with "-p <dir>". but even then when I go to about:profiles and click "launch in new browser" it's still pooping with this error. So Am I doing something wrong or it is just impossible to do this seamlessly? is there a better(correct?) way to achieve the same functionality?

thanks for reading, ill humbly take any advice.

EDIT: I have copied the profile's folder to a separate partition which is auto mounted tried it on Ubuntu (at this time it had been working just fine) and after using it on Arch when I was back on Ubuntu it was displaying this error

Dear friends at mozilla.org,

Thank you for your excellent browser, which I've used almost from its first versions.

I'd like to compile its source code, which I've downloaded from your website, into a working browser. I've spent several days, and get only as far as not-terribly-helpful error messages, that indicate strongly that I'm using versions of tools and libraries that the source code doesn't like.

I'm using

 linux kernel 6.1.0-13-686-pae (from Debian)
 gcc 13.2.0-9
 perl 5.36.0
 python 3.11.7

It's sufficiently important for me to compile firefox that I'd install a fresh linux system for this purpose. Could you possibly recommend to me what linux distribution I could install, and versions of compilation tools, header files, libraries, etc. that are known to work for compiling firefox? I'd be glad to report back to you my results, to help others who'd like to compile firefox.

In case you're wondering, I'm perfectly competent in installing software, including compiling anything. I'm an M.I.T. graduate, and have been a professional computer programmer for most of the half-century of my working life.

Thank you kindly for any response that you have time to send to me.

Very truly yours,

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

When I click the address bar, Firefox lists favorite sites. How do I disable this list until after I've typed?

I don't want the list because I don't want to be distracted by these sites.

While they are safe-for-work, I'd rather "fun" sites didn't come up when I'm working with other people.

Bangirot says technical problems when I want to see my received bankgiro payments. Win10 with Firefox, I can't see payments on that machine for a month soon. I have reinstalled firefox now. Still same result. With Android phone and firefox it works, but without printer. With another browser on Win10 it works, but not with firefox. Swedbank internetbank or bankgirocentralen can't help me. They have not heard of such problems.

Internetbank works, but with their connection to bankgirot it says, tehnical problems. If I login to bankgirot directly, it says tehnical problems.

So far its only the combination with this machine and firefox that gives this result. I haven't tried with another machine yet.

I have used firefox very long time without any problems.

When I open a new tab in FF, a row of 8 boxes appears below the search bar where I can add shortcuts. I currently only use 5 of them, meaning there are 3 empty boxes left over. I don't want to have them show history, or recommended websites, or anything of the sort that might distract me; the shortcuts should only be those I actually intend to use, of which there are only 5. To my knowledge, the only easy way to add/remove shortcuts is to adjust the number of visible rows, but this only allows modifications based on multiples of the original 8. Like in Chrome, can I actually remove any excess shortcut boxes I don't want to use? I feel this is a very basic customization I'm sure Firefox should be able to accommodate.

I've included a screenshot of my FF new tab, where the three empty shortcut boxes I'm referring to can be seen. Thank you in advance for any assistance!

I signed into Firefox on a lab computer that has too little storage space to install plugins (<1MB storage space left.)

Naturally, plugins did not install. I wanted to ensure that Firefox would not even attempt to install them in the future, so I set the browser not to sync add-ons.

I don't know whether what follows is because of that setting, or because I set it too late. In either case, my dozen or so plugins on my main computer have now all been uninstalled. I don't know the names of all the plugins I was using anymore.

1. Can I recover my automatically uninstalled plugins? 2. Can this bug be patched?

In the network tab, I can see all the html, css, and js loaded on my page.

When I click on Start performance analysis (stopwatch icon in bottom left), it shows pie charts of the asset sizes, but CSS is missing.

When I click the back button, the network tab only shows 14 items, and no CSS.

I'm using Firefox on Linux Mint, installed through the software manager.

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

I have firefox for Linux and I want to be able to access a specific http website pretty much without any security restrictions from firefox at all (it is a trusted website), however whenever I try to add it to exceptions like this: http://<website>, it automatically becomes added as https://<website>. What can be done?

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

Firefox won't start after updating to version 123.0 on Ubuntu OS.

At the same time, no errors will appear, and there is also no specific crash report that would help understand the reason.

How to restore the previous version without losing profile data?

I use Duck duck go as my default search engine. I've noticed that after the last couple of updates, the default has changed to Google. This has not happened before. There must be a bug somewhere that is causing this to happen in the new version of Firefox.

As you can see in this screenshot, Firefox is constantly bugging me with this popup.

I am not able to find an option to disable it once and for all - and I am not able to set it up as my default browser (professional reasons).

It breaks an automation script that I am working on.

Much appreciated :)

Hi,

  I am running the latest Firefox v122 (firefox_122.0+build1-0ubuntu0.22.04.1~mt1_amd64.deb not snap)

and when using the --profile option to specify the startup profile it fails to start even on a NEW system that never ran Firefox if I give it a directory that resides on a mounted ext3 filesystem.

  All the permissions are OK and yet running strace I see an error and after a few second will get the

generic pop-up with the error message: (after a few seconds)

Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

 Running the SAME from /tmp works fine, but I need the profile to reside on a persistent storage area

so if the LIVE distro restarts then it can restore the previous session, bookmarks, options, etc...

============================================================

 The 2 directories were created identically and have the exact same permissions:

xubuntu@xubuntu:~$ mkdir /tmp/firefox3

xubuntu@xubuntu:~$ mkdir /media/xubuntu/sys_n01_home/mozilla/firefox3

xubuntu@xubuntu:~$ ls -ald /tmp/firefox3 drwxrwxr-x 17 xubuntu xubuntu 1080 Jan 21 22:05 /tmp/firefox3

xubuntu@xubuntu:~$ ls -ald /media/xubuntu/sys_n01_home/mozilla/firefox3 drwxrwxr-x 17 xubuntu xubuntu 4096 Jan 21 21:13 /media/xubuntu/sys_n01_home/mozilla/firefox3

============================================================

The only difference is that one is mounted on tmpfs and the other is on /dev/nvme0n1p2:

xubuntu@xubuntu:~$ df -k /tmp/firefox3 Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 32560016 351528 32208488 2% /tmp

xubuntu@xubuntu:~$ df -k /media/xubuntu/sys_n01_home/mozilla/firefox3 Filesystem 1K-blocks Used Available Use% Mounted on /dev/nvme0n1p2 195751828 51056068 142695768 27% /media/xubuntu/sys_n01_home

============================================================

When starting firefox with the /tmp/firefox3 profile directory it works fine and starts up:

xubuntu@xubuntu:~$ firefox --profile /tmp/firefox3

newfstatat(AT_FDCWD, "/tmp/firefox3", {st_mode=S_IFDIR|0775, st_size=1040, ...}, 0) = 0 newfstatat(AT_FDCWD, "/tmp/firefox3/.parentlock", {st_mode=S_IFREG|0664, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, "/tmp/firefox3/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11 fcntl(11, F_GETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0, l_pid=-487933736}) = 0 fcntl(11, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0 uname({sysname="Linux", nodename="xubuntu", ...}) = 0

BUT when using the persistent storage on the real filesystem (but SAME exact permissions) it fails:

newfstatat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3", {st_mode=S_IFDIR|0775, st_size=4096, ...}, 0) = 0 newfstatat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3/.parentlock", {st_mode=S_IFREG|0664, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11 fcntl(11, F_GETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0, l_pid=1519466008}) = 0 fcntl(11, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = -1 EACCES (Permission denied) close(11) = 0

Am I doing anything wrong or is this some weird startup issue / race condition in the parentlock management?

Thank you for looking into this.

PS: I can upload the full strace file for both scenarios if needed. Thanks again.
