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.

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?

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 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.

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 am getting notices that I need to update my FireFox. I went to update and saw this message "updates disabled by your system administrator". What do I need to do to be able to do the update. Email:[edited from community support forum]

Hi, Is there a way to get rid of the messages about the upcoming browser update for Firefox on Linux?

The message appears at the second launch on a new profile and then at random moments in new tab. Message attached.

I tried already whats below, but its not helping: user_pref("app.update.enabled", false); user_pref("app.update.silent", true); user_pref("browser.startup.homepage_override.mstone", "ignore"); user_pref("startup.homepage_welcome_url.additional", "");
