@gbb There is a way to install standalone on Mac. It's not straightforward.

I wanted to see how things work out a couple of days and to make sure everything is ok. And, yes, that's the way it is! Thank you guys for helping me :)

No idea why renaming doesn't work for me withing Ctrl-B. And there is the issue of not being able to change the URL. Anyway, thanks for clarifying the bookmarks folder/tool bar

@TbGbe @Pesala I had a chance to play with this a bit over the weekend, and was able to figure out what Pesala was talking about. Yes, I think the Standalone installation option will work fine for what I'm trying to do. It would still be nice to be able to "integrate" multiple profiles into a single installation of the browser, but for my immediate purposes (keeping my personal data off of our work backup server) it will do just fine.
