Very helpful.
Открытие сайта разработчика после каждого обновления - идиотизм. Нормальные расширения так не делают. А в остальном расширение полезное, но этот идиотизм вымораживает.
Fantastic work Chris, thanks so much.
This is a must have for web developers. I have no idea how I ever got along without it. My only gripe is that unlike the Firefox web developer extension, every time I refresh, I lose all of my tweaks such as outline block elements. Firefox version had a setting to make the changes stick and reapply after refreshing which I do a lot when developing. It's a downer but the plugin is still well worth using. (Ignore the one star ratings below).
Forces you to accept desktop notifications from all sites.
Very nice...liked a lot.
I don't like a rule which displays notifications on all sites by default. Even though the developer's intentions were good. I'll be making a fork and removing this.
sirve bien chivo
Forces a rule that allows any site to create a notification.
This popup enforces a rule that lets any site create notifications !
