677795 - Firefox window title doesn't always match currently-selected tab after switching tabs

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[Justin Lebar (not reading bugmail)]

It looks like there are lots of bugs along these lines, but they're all resolved (most INVALID or WFM).

What I've been observing occasionally for the past few weeks now is that when I switch tabs, the window title doesn't always update immediately.

Sometimes it takes a second or two to update, and sometimes it never updates at all.  Switching to another tab and back usually fixes the stuck title.

I suspect this may be due to the way Firefox / Gnome handles long titles.  I often see the delay when switching tabs to [1] and [2] while my browser window is small enough that the whole title doesn't fit.

Looking through the many, apparently, similar bug reports, https://bugzilla.mozilla.org/show_bug.cgi?id=250423 looks much the same but is closed.

Even running in safe mode, switching tabs, opening link in new tab, creating a new tab, going 'Back' or 'Forward', possibly other such actions result in a window title reflecting, usually, the previous active tab.

Also, in Mail/News, window title bar is showing what was previously being viewed wrt message, folder, account.

Pressing 'PrntScrn` causes the window title to be updated to correct, so I'll attach a digital photo showing title of the previously active tab being displayed.

Thanks.

I appreciate the effort, but it's really not necessary.  Fixing this bug isn't a question of observing the effect, but rather of being able to understand why it happens.
