Brave Dev crashed – while I wasn’t using it (i.e., the report that it had crashed appeared on-screen while I was in Tor).
When I reloaded I noticed that not all windows that had been open (not including Incognito windows) appeared in the Window dropdown menu.
I thought they were gone but when I opened Tabli (tab manager) they displayed there (with tabs intact) & I found I could select them (or tabs in them), after which they then appeared in the Window dropdown menu.
Haven’t experienced this before.
(This is in Brave Dev on a Mac.)
