Status: RESOLVED DUPLICATE of bug 1095729

(Firefox :: Tabbed Browser, defect)

Since I've updated to nightly with e10s, when I restore a session (with maybe 8 windows and 120 tabs), some of the windows remain in a pinwheeling state until I switch to another tab. When I switch back to first tab, the page is loaded normally.

Other than switching tabs, I've tried:
-clicking on a bunch of UI element
-hitting refresh icon and refresh hotkey
-pressing `enter` in the url bar
-zooming the page
-clicking the hamburger menu
-opening the menu bar menu

None of these actions do anything. The only thing that has worked is switching to another tab and switching back.

The same pinwheeling state happens when I drag and drop a tab from one window to another, and again I have to switch tabs and switch back for the content to show up. Additionally, in the d-n-d case, the page title never changes from "New Tab" and the url never appears in the url bar

This is under Ubuntu 14.04, nightly 36.0a1 (2014-11-10)

Whoops - bug 1075122 seems to refer to the URL bar throbber, and not the tab throbber.
