How does Firefox determine where the Kerberos keytab is located?

The default location for Kerberos keytabs on a Linux box is within /tmp. /tmp is very temporary these days and is wiped on reboot and it looks like on the various power save/restore.

So, I decided to move the keytabs to a static location to allow them to work according to the usual schedules and timeouts, instead of being wiped out on a whim. I settled on /var/lib/krb5tabs/krb5cc_%u I configured that within /etc/krb5.conf

I use pam_winbind from Samba to do the Kerberos login and the keytab is filled in and the environment var KRB5CCNAME is set correctly.

Before the change of the location of the keytab from the defaults, everything works fine apart from after a resume and creds need re entering (which is the pain I am trying to avoid).

After the change, Evolution is still able to authenticate via Kerberos but Firefox is not. So, does FF just assume defaults or actually follow KRB5CCNAME - which seems to be the standard for Kerberos?

When I was previously using Firefox in Kubuntu 22.04, if I downloaded something I could go to the Downloads icon and click on the download and it would open in the desired application. After a failed upgrade to 24.04 I had to do a reinstall and now in Kubuntu 24.04, if I click on a downloaded file it will always bring up a window with "Open the file link with okular?" and the buttons Cancel and Open Link below. How do I go back to the previous way of it working?

How can I stop advertisers from changing my 'Settings' fields 'Home page and new windows' to their URL which brings up their page before I can enter my password? I'm on Linux Desk Top.

I am (again) running into trouble with spelling.

I got this offered to me: https://www.google.com/search?client=ubuntu-sn&channel=fs&q=how+to+set+dictionary+in+firefox

Doesn't quite work. Wrong things declared, etc.

I see a "badly spelt" word. Double click, go to add dictionary.

To the best of my knowledge, it is installed. Others point me to about:config spellcheck.dictionary

But that is not really offered to me when I am typing the name. So probably doesn't exist.

I'm trying ITMT, but would like some help please.

Hi,

I have a laptop with an AMD Ryzen 7 8845HS CPU, including a Radeon 780M iGPU, running Ubuntu 24.04. In order to fully utilize the GPU by supporting OpenCL acceleration I installed the additional drivers by: `sudo amdgpu-install --usecase=graphics,multimedia,opencl --opencl=rocr --opengl=mesa`

After that programs which benefit from OpenCL acceleration recognize the GPU, however firefox starts crashing with the following error msg:

XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

It seems that the AMD GPU drivers registered their libraries in `/etc/ld.so.conf.d` as 10-rocm-opencl.conf, 20-amdgpu.conf which means that libraries within the given folders are found first.

This applies to the libwayland-client library, which is used by `/usr/lib/firefox/libmozgtk.s`:

ldd /usr/lib/firefox/libmozgtk.so | grep amd libwayland-client.so.0 => /opt/amdgpu/lib/x86_64-linux-gnu/libwayland-client.so.0 (0x00007013767bf000)

Interestingly the same `libmozgtk.so` library is used by thunderbird:

ldd /usr/lib/thunderbird/libmozgtk.so | rg -i amd libwayland-client.so.0 => /opt/amdgpu/lib/x86_64-linux-gnu/libwayland-client.so.0 (0x00007d44b0f41000)

However thunderbird just works fine, so I expect that there might be something wrong with firefox utilizing this library.

Maybe I should also mention, that I'm not even using wayland as desktop compositor, but good old x11:

echo $XDG_SESSION_TYPE x11

Is there any way to further debug this issue?

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

I'm attempting to sync my account between a Windows host and a Linux host. Logging into my account on Linux brings up a "Authorize this sign-in" window that demands entry of a 7-char "Authorization Code" (not the same as a six-digit authentication code) which is emailed to me. After entering the authorization code, a window appears stating "Bad request - Something went wrong. Please close this tab and try again." This happens consistently, and only on the Linux host. Firefox 134.0.2 mint-001 1.0. Linux Mint 22.1. Any ideas about what went wrong?

Hi - I wanted to migrate all my changes made in the flatpak app to the aur version. I noticed the profile content has a different structure in both - aur and flatpak configs. And any attempts to replace profile content with the other resulted in browser ignoring these and initing new config files. Was wondering if my config can be ported over or thats not possible thanks.

Dear Mozilla Team, I installed my Fieefox on Linux Mont on an old Laptop I use as my daily machine. Firefox however after login does not sync to my previous installs. I have installed and removed firefox on my mobile (iphone), with no change. Also re-installing and singning out, signing back in did not help. What can I do to get all my bookmarks and PWs back?

I try to install Firefox directly from the Mozilla repository.

For that, I read the article "Install Firefox on Linux" and followed the install instructions in first chapter "Debian-based distributions" step-by-step. (article https://support.mozilla.org/en-US/kb/install-firefox-linux)

Unfortunately, with every attempt to install Firefox, the Firefox LinuxMint (Ubundu) package will be still installed. The command to priorise the Mozilla repository seems to have no influenace.

How can I prevent/avoid using the LinuxMint/Ubundu repository? I wan't to install and update Firefox direct from Mozilla source.

I'm using Linux Mint 22.1 Xia base (Ubuntu 24.04 noble)

The visual and audio notifications for incoming emails being posted to the inbox of gmail under Mozillia Firefox do not function correctly when ran on a Linux Mint operating system computer.

I can get the visual notifications to work as long as the Firefox is open but once that session is closed the visual notifications are no longer issued, i.e. the setting to issue those notifications are not being saved upon closing of the browser.

I can get the audio notifications to work on a sporadic basis. I go into the settings on gmail and choose one of the audio sound notification choices and it works a few times when income emails are received into the inbox, but then just stops even if the current firefox/gmail session is still open.

My theory is that those firefox/gmail settings are not getting preserved/saved in proper manner to be available for subsequent sessions of firefox/gmail because firefox/gmail does not understand the FILE STRUCTURES of Linux Mint Mate so that those settings can be properly preserved for use by subsequent sessions of firefox/gmail.

Please consider fixing this.

Thanks.
