Please Update for 4.0.1 Rated 5 out of 5 stars
It is one of my number one add-ons. But sadly it does not work in 4.0.1 with whatever trick. You can set browser.sessionstore.max_concurrent_tabs to 0 in about:config and in the add-on When Restoring Tabs From a Previous Session to Default. Then you do not have to press F5. But Keep Tabs From Special Pages Loaded still does not work then. Tested all this with version 2.1b2.
Still give 5 stars because I hope it will get fixed. Otherwise I will go back to FF 3
