Hallo!
Ich habe dasselbe Problem (bei jedem Tab-Wechsel erscheint ein Throbber, auch wenn die Seite eigentlich nicht (?) neu geladen wird. Zudem dauert es öfters auch länger, bis überhaupt auf den anderen Tab gewechselt wird.)
Die Information bei mir:

Zur Information für Dich:
Bitte vor dem Posten lesen sagt unter Punkt 5:
ZitatEröffne Deinen eigenen Thread im Forum. Auch wenn das in einem anderen Thread geschilderte Problem auf den ersten Blick identisch mit Deinem Problem ist: es gibt immer die eine oder andere Abweichung (anderes Betriebssystem, andere Erweiterungen, andere Sicherheitssoftware usw.). Ausserdem werden Threads, in denen mehrere User das +- gleiche Problem schildern schnell unübersichtlich und es könnte sogar sein, dass Deine Frage schlicht und einfach übersehen wird.
Deswegen habe ich Deine Frage abgetrennt von hier:
Firefox 49: Tab-Wechsel langsam
und in einen neuen Thread verschoben.
