I've been on Chromebooks for a while.  However, since I had to recently try a Mac, I figured it was time to give Firefox a try again.  After two weeks of trying, I've given up.  At least for myself, I figured I'd write down the reasons I've given up.

Reasons:

• There is no way from the tab context menu to move a tab between windows.  I typically try to keep no more than 3 windows open at a time.  Ideally one, but maybe a second.  Without the ability to through the context menu to move a tab, I need a very large screen (not a laptop screen) to move tabs between windows.
• I couldn't find a way to take a URL and turn it into a custom search.  This really is a critical feature as it allows me to use short names to access specific searches.  E.g. search code (cs), show a calendar (c), etc.
