I've loved this extension for years now. Strangely just recently it's started acting very funny and I haven't even updated firefox yet (Running 32-bit 54.0.1). I understand it won't work in the latest version. But suddenly now when I hit "Add to favorites..." it locks up the window, and maybe a minute later the dialog might pop up, or maybe I have to force a browser restart. I've tried moving a bunch of old favorites to another non-favorites folder so it doesn't have as many to load, but it's still very laggy. I don't know if one of my other extensions auto-updated recently and somehow broke it, but I just can't tell what's locking it up.
At any rate it's looking like this and "Windows Favorites" are no longer going to be an option soon depending on what Mozilla decides to do in the future about file system access permissions or something like that, so I might have to finally migrate to the built-in bookmarks feature and hope that it's at least functional for my needs if not ideal, I'll have to adapt I guess. This was one of the main reasons I wasn't using the 64-bit version too, so maybe I can run that more often. I do know I usually have a /ton/ of tabs open, usually just as placeholders for stuff I eventually want to go back and read, but I guess I should go through and bookmark them all and then close them, it would most likely be a /lot/ more responsive. Anyway, more RAM would be good.
