I feel stupid but I can't find a way to add buttons for single addons to the menu-bar on top. I know in the past this was possible but now I have to click the button for "extentions" and there all addons can be found (see first screenshot). I would rather have buttons for single addons available in the menu-bar, for example for my ad-blocker. I tried "customize" but there the addons don't show up for some reason (see second screenshot - sorry that it's in german). I am not browsing in private mode in case you're wondering.

Edit: Okay nvm, I figured it out already. I didn't know I had to right-click the addons while in the extension-menu. I still find it kind of weird that the addons don't show up in the customize-view anymore.
