I've bookmarked topics and I get notifications. When I click that notification it takes me to the post that was bookmarked and the bookmark shows in blue with a little clock under the post.
To cancel the notification, I click on it and and click the dustbin icon where I have the option to edit the notification or delete it.
This has changed; when I now click on the blue bookmark icon, I get a small popup to select either edit or delete.
I might have missed a forum banner (top of the forum) that informed me about this change or it was never changed.
I do not mind this change but I don't like it when things on the forum seem to change without announcement. We have had the issue with Firefox (still ongoing) and I'm confident that there were changes in the past that made me wonder if I am going senile.
