I tried AdGuard but downloaded it from their website and not through the app store and it wasn't good at all so I trashed it and went to the app store and downloaded 1blocker. I have block ads, block trackers, custom rules and the 1blocker button activated and so far it's working very well.
It's just that darn spinning beach ball half the time I click on the bookmarks menu
How many bookmarks do you have? Also, it helps to keep bookmarks nested in a folder inside a folder. The top-level folder will show when you click bookmarks menu. If your bookmarks are residing at top-level, it’s going to be a pain as the menu tries to load them all.
