Thanks for the answer.

I tried it this way, but there are so many bookmarks from 9gag that it would take an eternity to select them all by hand

Dear forum members & support,

I use Opera since a very long time, and over the time I collected a vast amount of bookmarks.
Now everytime I open the bookmarks page, it takes a few seconds to open the page, and an even longer time to open the actual bookmark.
Now I wanted to ask if there is any possibility to delete bookmarks from certain pages (e.g. 9gag) in a fast way.

I opened the bookmarks.bak file, but I don't know a way how to delete the bookmarks of a specific page.

Thanks in advance,

Mrluca
