604758 - Tabcandy randomly disappearing tabs

Status: RESOLVED DUPLICATE of bug 598600

(Firefox Graveyard :: Panorama, defect)

Description

[Boris Zbarsky [:bzbarsky]]

You're going to hate me for this....

BUILD: 20101012 nightly

STEPS TO REPRODUCE:
1)  Have a window with a bunch of tabs (15+)
2)  Walk away from the computer for 20 minutes
3)  Come back to discover that about 2/3 of the tabs are gone
4)  Think that maybe tabcandy has the tabs; open tabcandy to discover that
    they're not there either (but see below).

ADDITIONAL INFORMATION:
Someone on #developers suggested that tabcandy has a tendendcy to tear tabs off into separate groups _and_ hide the groups.  So I tried opening tabcandy again and moving the tab group with the 7 remaining tabs away from the top-left corner.  At that point, I discovered that my missing tabs were in fact there, one tab group per tab.  The tab group items were sized so small that it was impossible to resize them; I ended up recovering by just dragging them all into the one group.

Oh, dragging one of the tiny icons would sometimes cause another one to resize into a window-like thing actually showing the preview.

In case it's relevant, I don't use tabcandy.  I'm pretty sure I haven't opened it in that window before.

Arlan _was_ poking at the trackpad for about 15 seconds near the start of those 20 minutes.  So it's conceivable that bug 598600 caused this.

After some review, I think everything in this bug is covered by bug 598600. Feel free to pile on over there.
