I like it so far, except that half my themes aren't yet compatible. It's my understanding that a bunch of popular extensions haven't yet been tested with 1.5 either, so be prepared to wait or step back.
So far my favorite new toy is being able to drag & drop the tabs around.
I installed it, and then when it tried to open up Firefox at the end of the install, nothing happened. I uninstalled and reinstalled, and the same thing. I double click the icon, and nothing. I hope they still have 1.07 available for download at the website.
EDIT: After uninstalling it, manually removing the firefox directory, and removing the 7 simltaneous versions of the Java runtimes that were apparently installed (the Java runtimes are apparently one of those programs that should be uninstalled before installing the updated version) and reinstalling (and actually closing all open programs like every installation program always asks you to do [though it's rarely necessary]) it works now. I don't know what it was, but whatever. And somehow all my plugins are still there. I wonder where Firefox keeps all the information on those, since it apparently isn't the main Firefox directory.
(edited by Mr. Boffo on 29.11.05 2321) In the real world, WWE believes that no matter what our race, religious creed or ethnic background in America, we all share the common bond of being Americans. American-Arabs are a part of the fabric of America, and they should be embraced by all of us.
An even better idea would be to deactivate System Restore when you get everything fixed, which will delete previous Restore Points, RE-activate System Restore and make a new Restore Point. That will give you a clean Restore for future use.
