I have no idea.........Before you insult my computer setup skills, all I did was download it and run it. It had the problems I mentioned so I removed the application and reinstalled. Same issues. I'm going to try again before I revert back but right now it's unworkable because it won't allow me to bookmark any pages so I'm using my Google bookmarks which, fortunately, I had kept most of my old bookmarks.
It took me two days and at least a half-dozen "do overs" to install my AT&T wireless network plugin and software. After doing it on one machine (you'd think I would have learned from that) it took two or three attempts to get it right on my other two computers after that.
I'm wondering what would make Bookmarks not work on yours though. Mine picked up the old bookmarks from 1.5 and I've added about a dozen or so since.
Maybe the "clock is ticking" on my installation and I am in for a big let-down in the near future.
What's nice is that the community of programmers that built, maintain and update Firefox are always making improvements and I'm sure they'll do the same for 2.0. I love the wealth of extensions that you can add to it. I keep expecting to see some kind of error message come up, informing me that I have installed too many extensions.
