After tor crash, firefox.exe (tor browser) shoots up to 50+% cpu usage and stays there til killed in task list

re: Tor Browser 8.0.6 (and also 8.0.3)

Have noticed since 8.0.3 to 8.0.6 that, every time tor crashes, firefox.exe (tor browser) shoots up to 50-60% cpu usage and stays there until i restart the whole browser or kill the process in the task list, thus losing all tabs.

Can we get a fix for this? It's annoying to have to save all tabs, restart, and then reload them again.
