Created attachment 8754851 [details] about_support As stated in the title, sometimes the window title do not update when switching to another tabs or opening a new one. This might be related to addons, however I'm as for now unable to reproduce it reliably even by deactivating/reactivating addons as it's not 100% reproducible. I did not manage to reproduce it on a new empty profile, but did not used it for a long time. Joined is an about:support result. Bug has been reproduced on Linux with GTK 3.20. OS X don't have window title so it's not possible to check this platform.
See also bug 1274594: generally those bugs can be observed in the same time. You can note too that when this bug is here, it's not acting on every tab switch bug can be observed on one switch and not on the following ones.
Because you've got noscript installed, I expect this is a dupe of bug 1265803. The other one might be, too.
