An essential toolbox for and web developer
I used this extension for a long time, but since it allows all notifications in Chrome I can't use it anymore. It's too anoying.
love it
This was such a useful plugin, until… this plugin adds http://* and https://* rules to Chromes notification center. Therefore, enabling this plugin allows all annoying notifications to pass through regardless if you tell Chrome to block all notifications.
Does not work. Does nothing.
This addon enable and locks notification settings chrome://settings/contentExceptions#notifications that are impossible to remove on http:// and https:// these are used to serve daily ads from www.wittyfeed.com. This is unacceptable. Reported to google, i hope you get banned.
My most-used browser extension for FF and Chrome. Never had issues with it, has tons of features, easy to use. I don't often contribute to extension developers, but I did donate to Chris Pederick because his tools are excellent.
Excellent
That's good
Suddenly this extension enforces notifications on http://*, https://* So any website is free to give you desktop notifications (no matter what you set in chrome - exceptions or off for all, this setting just overrides everything... basically, you can not turn off notifications as long as you have this extension installed) Uninstalled :( Too bad for the usefulness of the extension. Was good while it lasted.
