Hi, I said most of it in the title. Somehow, my Firefox DisableAppUpdate policy got set to 'true' & when I try to change it Firefox says sorry "this is managed by your organization". But I'm not currently signed in to an enterprise network. This is on private wi-fi. Can you all fix this? I need to be able to manage policies like this *for my personal browser*, less is not okay. Thank you for your help.

Hi, Currently, my Firefox 133.0's default behavior is to open bookmarks in the currently active tab when clicking on them. This is fine for some applications/websites but impractical for others. With webmail clients, IP surveillance cameras, or weather forecast sites this can become a real pain, especially if someone keeps multiple instances (windows) of Firefox open across multiple virtual desktops (as I do). I end up opening these sites over and over again in different tabs.

I'd like specific bookmarks to be opened in a new tab/window if and only if that site is not already open; otherwise, bring that particular tab/window up instead of creating a new one. How could this be achieved?

Thank you very much!

My laptop operating system Linux ubuntu crashed. I had to reboot using new linux OS Linux Mint. Laptop now working but have lost all my search. I sometimes use DuckDuck to serach. Help in recovering my bookmarks.

I've been getting warning messages telling me to update Firefox or security certificates will expire on 14th January. I clicked on Help -> About, but it doesn't check for updates. I also tried going to Preferences, but I still can't see a way to install updates.

I downloaded a version from here https://www.mozilla.org/en-GB/firefox/download/thanks/ I unpacked it into my home directory, but I'm not sure how to install this version.

I'd like to be able to import my current session into the new version of firefox.

Any help would be appreciated.

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?

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.

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?

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?
