The confirmation has changed the structure so that the sidebar content is isolated.
First of all, I worked briefly on separator, but in the long run, there are things I need to work on again so that the color of the sidebar context menu works with the theme.

This is probably related to this, so I'll just add to this thread, instead of opening a new one.

There's no separators at all when right clicking items in the Library window. And, as mentioned by the OP, Sidebar separator colors are not right, they're too dark to match the background. When right clicking items directly on the Bookmarks Toolbar or using the dropdown menu, everything is displayed correctly.

This is on Win11, Firefox v117, it was the same on v116 as well.

It was a smaller task than I thought.
Now it should work correctly.
Could you test it?

Seems to work fine now, thanks!
