Changes

I disagree with "Set the window restrict option to 3 (so that when the user chooses to have tabs opened instead of windows, windows with specific sizing parameters are not opened in oddly sized tabs)", because it will make the option not work for a huge number of sites. "Set the re-select-on-close behavior to select the previously viewed tab, when tabs opened by document or external sources are closed." seems strange and inconsistent. I agree with most of the rest.

Isn't it late in the Firefox 1.5 cycle to make these kinds of changes?

Jesse, can you point out a couple of sites that will break if we set the default force-tab behaviour to option 3?
