Autoload doesn't work for me either anymore Rated 5 out of 5 stars

Even set browser.sessionstore.max_concurrent_tabs = 0 which made BarTab work in Firefox 4 Beta 10 but now with Beta 11 it doesn't work at all. I tried setting it back to the default set browser.sessionstore.max_concurrent_tabs = 3 but that did nothing. Even tried the beta version of BarTab and still nothing. Please fix. Thanks.
