Title:
firefox is unresponsive for the first 10-15 seconds after it gains
focus
Status in “firefox” package in Ubuntu:
New
Bug description:
I keep firefox on its own desktop, and switch to it via a keybinding.
This problem manifests itself even when switching focus via mouse on
the same desktop, though.
Basically every time I come back to firefox, it appears to ignore my
input for a good long while. I am not seeing any swapping, and even
the mouse cursor does not change in response to hover events.
The effect goes away when I restart the browser, but slowly returns
the longer I leave it running.
This only started happening this weekend, and it happens in both unity
2d and 3d.
