When i create an account in blue named AK-M AK-M will not appear on the screen- There i find instead "Neuer Tab" ... How to solve this Problem? Thanks for any hints. Josef Schwendt

Good morning, today I downloaded Debian 13 Mate version and to install Firefox I entered the following commands taken from https://support.mozilla.org/it/kb/installare-firefox-linux#w_installare-firefox-tramite-il-pacchetto-deb-per-le-distribuzioni-basate-su-debian-consigliato and the commands were

sudo install -d -m 0755 /etc/apt/keyrings

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

echo ' Package: * Pin: origin packages.mozilla.org Pin-Priority: 1000 ' | sudo tee /etc/apt/preferences.d/mozilla

sudo apt-get update && sudo apt-get install firefox firefox-l10n-it

but I get this result OpenPGP signature verification failed: https://packages.mozilla.org/apt mozilla InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Signature by 35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3 was created after the --not-after date.Il repository "https://packages.mozilla.org/apt mozilla InRelease" non è firmato.

What mistake could I have made? Apart from the fact that now we use sudo apt update && sudo apt install Thank you in advance for your response.

Hi, an addon I was using was automatically disabled, with a banner containing the following text and a link to "see details": "This extension is restricted for violating Mozilla’s policies and has been disabled. You can enable it, but this may be risky."

This is vague and unhelpful, but maybe the "see details" link will provide more context.

If I click this link, I go to a new page which has the following: "This extension, theme, or plugin violates Mozilla's add-on policies. Version deleted"

This is even worse, as it's not clear what has happened, what I should do (if anything) and gives me no confidence in the process. Does "Version deleted" mean the developer deleted this, Mozilla deleted this, is it just this version or is it all versions? Why what it deleted, was there a security problem I should be concerned about, or does it no longer run on supported Firefox releases?

While I would be interested the reason for the specific addon, it seems to me there's a more important process and UX issue here.

Side note, there seems to be no topic for addons, which seems like an oversight.

Hi Mozilla,

i stumbled upon an extension called 'unhook' which allows to hide a wide selection of content from my view on youtube. This is amazing! Now I can watch my favourite channels without annoying stuff on every side. I would really appreciate to have something of this kind as a native feature in Firefox. So please consider this a suggestion right away or point me towards the place where I can suggest this feature correctly - if there is such.

Thanks a lot for Firefox!

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "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."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

I can play this video with Chrome:

       https://www.bitchute.com/video/svoRcPeYjlCb/

It appears to be unplayable via Firefox for Ubuntu, 143.0.4 (64-bit), or earlier versions.

Is this some sort of censorship?

I'm using Firefox 144.0, running on Ubuntu 24.04. I have seen many "fixes" for this issue, posted here and elsewhere. None work for me. Tried turning off Privacy Badger and uBlock. Cleared Firefox cache. Tried Safe Mode. No go.

On the same machine, the problem does NOT occur when using Chrome.

I've seen multiple mentions of this issue, various places. I've tried all the fixes I've seen, save doing stuff with Java scripts.

Suggestions?

Thanks in advance for the help!

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?

I created an account on an old PC, in the account it is visible as kos-work-note, now I am on a new kos-ltop, and there is no data at all in the browser, why is that?

Sorry! 0 results found for ‘I do not recall my password for updating, what do I do.? For past 30+ years have been US Navy, no access to persona computer like I am now ready to update any of my home computer, forgot password for’ for ‘Firefox’

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?

In Chromium you can go a page backward or forward by swiping one finger to the left or right. This works really well. I have been missing this feature in Firefox for years now. Without it navigation in the browser is tedious on Linux tablets or phones.

Is something similar ever going to be implemented?
