I can't believe it took me almost 1/2 an hour to find this page [and relog in] to post this. After a restart I had 5 separate windows each with the same 5 pinned tabs. After closing 4 the four extra windows I realized 4 or my pinned tabs also disappeared and every new tab I opened to try and resolve it ended with yet another duplicate window with the same tabs. Ready to delete this pathetic browser. Had already moved my most used tabs to another browser because of lagging issues and after this latest issue.....well now all tabs have been exported to different browsers. Will not miss it.
