Not working 100% with 0.3.7.3 Rated 3 out of 5 stars
Used it with FF2x without issues. With FF3x (specifically 18.104.22.168), tabs are not being saved correctly. Tab count and site, but the actual page on the site is not always saved.
Example, I go to http://www.somesite.com/some/sub/page.html then I close FF, and restart, the correct page is there, then I change to /someother/page.html on the same site, and close FF. When I restart FF I'm back on http://www.somesite.com/some/sub/page.html and not where I left off.
Very often clicking the X in the top right, results in NO tabs being saved, but choosing File, Exit, and the tabs are (just not always updated to the correct page).
Hope this will be corrected soon. In FF2 this was working correctly, with FF3 its not.
And please add an option to save current tabs, native FF3 has this option (via add-on), but Tab Mix Plus doesn't....
