not long ago i noticed many notifications i got on twitter (yeah i don't really use twitter). logged in and looked into my notifications: no retweets, no liked your tweet, no new follower, ... only all these "in case you missed" notifications with no way to disable them.
googled a little bit and only found people who asked how to disable them but didn't find solutions. thank you twitter not
it annoyed me so much, that i wrote a small greasemonkey script:
$('ol#stream-items-id > li[data-component-context="generic_activity"]').hide();
this breaks the continuous loading of older notifications. the workaround is to resize the browser window, then the loading is triggered.
of course the notification dot indicator still shows such notifications as new but at least they don't clutter everything.
