User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.12) Gecko/20101027 Ubuntu/10.10 (maverick) Firefox/3.6.12 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.12) Gecko/20101027 Ubuntu/10.10 (maverick) Firefox/3.6.12 Using Panorama tab groups using settings that prevent tabs from loading at startup, makes Panorama "forget" groups after a restart. This is highly inconvenient, as those two features shine together: Allowing a high number of tab groups without chocking the browser at startup. (Not to mention snappier startup times, that can improve the perceived speed of the browser. Also avoiding possible media content from playing, saving bandwith and loud noises at startup) While bartab is more convenient (allows on-demand loading, instead of loading the page on a misclick or using the mousewheel), this could be considered an incompatibility with the addon. However, the same behavior exists modifying browser.sessionstore.max_concurrent_tabs to 0. The problem seems that the browser doesn't know what to do with tabs that were never loaded that session. So organizing tabs into groups and rebooting will lose the group settings. This behavior is present in the latest Minefield build as of Nov.28th, 2010. Reproducible: Always Steps to Reproduce: 1.Install bartab 2.0 or modify browser.sessionstore.max_concurrent_tabs to 0. Restart Firefox. 2.Organize some unloaded tabs into groups. 3.Restart Firefox. Actual Results: Any tab not loaded in that session will be part of another group or returns to the original position. Tab ordering seems to be random as well. Expected Results: Keeping the groups as organized during step 2.

Does this still occur with more recent builds?
