"AntDM is not installed" error

Hi! been using the latest version 1.14.2 for a couple days without any issues, until now. Now, the AntDM icon in firefox says that Antdm is not installed!
Wtf? of course it's installed. I un-installed and re-installed the extension several times, to no avail. the problem persists. What is going on????

Something weird is going on. I opened chrome and I started getting notifications that all my extensions stopped working...
maybe another certificates issue, like the one we had a few months ago?

never mind, logging out and back in again seems to have fixed it. weird, though...

If yesterday everything worked, but today it stopped, then my first (funny)
recommendations for all users:

- reboot browser
- reboot PC
- reinstall the software
- reinstall integration https://antdownloadmanager.com/addons_m.php
- maybe your antivirus disables the software

It’s not funny, but it helps in most cases. I have to post this to FAQ

Fortunately, this time all it took was just logging out and back in, not even rebooting. still, very strange behavior.

Here there was no issue on Firefox, Vivaldi and Chrome.

like I said, very strange behavior, probably some fortuitous event
