[Bug] High CPU usage after closing busy tab #114

Closed nneonneo closed 8 years ago

nneonneo commented 8 years ago

After closing a busy tab with Tab Tree installed, the CPU usage of Firefox goes up and stays high (even when idle).

Steps to reproduce:

  1. Open a tab that takes a while to load, e.g. The Verge.
  2. Close that tab before it finishes loading.

Watch as Firefox now consumes significantly more CPU resources. On my machine, Firefox goes from ~5% CPU when idle to ~40% CPU when idle (of a single core).

Patch forthcoming.
