Status: VERIFIED FIXED

probably from bug 2015921 combined with previous bug 2012536 generally tab state manager is probably detecting a location change and deciding to open the sidebar ??

this is made worse by bug 2016552 as switching to classic doesn't get rid of the reopening behavior

bug 2016402 seems to have fixed but i'm not sure if it was an intentional behavior change and might have introduced other bugs
https://hg.mozilla.org/mozilla-central/rev/f807fe2893f3

the existing handoff code detects a location change from fullpage assistant to open the sidebar as part of original bug 2012536

and seems like the way it starts a new conversation sets enough state to remember to keep the sidebar closed on internal url changes like on calendar/docs

I cant seem to reproduce this issue at all, I think even in the past it only happend once, I will close this issue for now and reopen if it starts to reoccur. Verified as fixed in our latest Beta 150.0b1 and our latest Nightly build 151.0a1 (2026-03-26)
