I've really missed being able to update bookmarks... Rated 5 out of 5 stars
Simple, functional, no restart required, and it scratches an itch I've had for years, ever since I went from Avant browser to Firefox (the "update bookmark" and "bookmark sync" were what kept me from switching for a long time).
I'm so glad to have this functionality available to me again, and I agree with the others that this (or something like it) should be a default feature of Firefox.
Thank you for this!
