Unknown Mozilla dev addon "Looking Glass 1.0.3" on browser

you mean the automatic update process, which can change every single byte of every file in every directory under Firefox's control? Because unless you want to live in a world where your browser can't automatically apply security patches and upgrade critical components, the fact that the application can update itself is very much not the actual problem (and with the new web extension addon system rathern than the old XUL system, addons are actually way less security-compromising-in-potentio than updates to the actual browser itself)

In Linux distributions you get it from the distribution repository, and automatic updates are disabled. So at least it's reviewed by a third party.

The automatic update process fails because it does not have right to install software on my box. The power of setting permissions and not blindly trusting software just because it is floss.

I would not want it to have this kind of power as the security patches and critical updates are provided by the kind people managing the distro repositories, and if it could update itself it would remove the third party patches required because mozilla has been refusing for 15 years to integrate correctly in my desktop environment but did integrate in the main competitor.

I'd argue there's a vast difference between an automatic update for something that was already manually installed, by the user, and automatically installing something without any indication to the user that it was installed. Worse, it's impossible to argue that this was even a useful extension.

I don't watch television, and I don't keep up with any popular modern shows. I had no idea what Mr. Robot was until looking through this thread, and the description text for the addon was, at first glance, suspicious. This was a terrible idea and isn't even remotely analogous to applying security updates automatically. If I have something I specifically installed, fine, I can expect those addons to be updated automatically. I don't expect them to side load something I don't even want. "Delight fans" my ass. You have to be a fan first, and I'm not even sure most people who are fans of Mr. Robot would think this is a particularly good idea.

Funny enough, the only thing I can think of that's even remotely similar to this is the "Hell, Dolly" plugin for WordPress, and that's installed out of the box as part of the distribution.

Actually an application being able to update itself is a security issue and terrible design. Strictly speaking it should have only have write access to say its cache files and a directory where you store downloads.

Its also moronic to have a different update policy per app that is achieved in 35 different UIs.

This is the norm on windows because they were late to the party as far as a central source of software and further managed to make it an unattractive proposition and didn't get much buy in from developers.

Totally aside from the implicit security issue the ui flow is also terrible. Either each of 35 different apps runs their own update checker process in the background wasting your resources and prompting you at annoying times or when you run an app one out of n times it will prompt you to update whereupon you will ultimately have to stop doing whatever you were actually doing and let it update itself and restart.

It is truly amazing that people not only put up with this ridiculous situation but defend this as a feature.

Your system should periodically on a schedule you set update every piece of software you own and never bother you otherwise.
