I have multiple computers on a Mozilla account. I sync history, tabs, etc.
It'd be pretty cool if columns for the computer and user were added to an appropriate table in places.sqlite.
When I search or browse history, generally I'm looking for only my history, not history from other users.
And, of course, improve the history dialog to include a filter for such.
That would allow me to find/reopen tabs that, for whatever reason, failed to reopen on relaunch of FF.
Thanks for reading.
