1.4 Rated 5 out of 5 stars

Nice addon. Thank you for making it.

However, "Replace Bookmark" option does not show up when someone is not hiding Menu bar and is using Bookmarks dropdown menu. User is then forced to drag the "Replace Bookmark" button from customize menu to get the same functionality.

Edit for v1.4: Hiding Menu bar, clicking on Firefox button, expanding Bookmarks button, doesn't show "Replace Bookmark" option. Also, adding/removing "Bookmarks" button from Customize menu onto/from a bar, then exiting/restarting Firefox shows/hides the Replace Bookmark button (on both Bookmarks Menu and Bookmarks button menu).

Keep up the good work.

This review is for a previous version of the add-on (1.3.9). 

No menu item in Firefox -> Bookmarks is to be expected. It's yet another menu that needs to be intentionally supported. Would you use it?

I can't reproduce the hiding problem. Could you write it step by step? Preferably here: https://github.com/dgutov/bmreplace/issues/new
