Бесполезное расширение. Написал скрипт, запустил в консоли браузера — работает. Вставил в Tampermonkey — скрипт не запускается.
Думал, что дело в @matches, @includes — написал регулярное выражение для нужных страниц, и скрипт всё-равно не запускается.

Расширение не справляется с его единственной задачей — примешивать JavaScript код к странице.

STOP PESTERING ME WITH YOUR UPDATE POP-UPS

no more a open source software for several years now and it never informed me about it

I'd rate Tampermonkey five stars instead of one but version 4.18 broke several scripts while version 4.17.6161 and other competing script addon like VM work fine with the same scripts. It's also being discussed on Greasy Fork but weirdly enough neither the author of the scripts nor the author of Tampermonkey seem to read, listen or care.

opens changelog when it updates, contributes to the spam

Why the heck i cant add to Firefox

I wrote a script and it just f*cking won't work.
I scavenged the whole help page and nothing f*cking helped.
I copied the whole script and threw it to the developer console. It f*cking works.

This add-on is a joke.
