Firefox 49 freezes (not responsive) on opening AdBlock Plus Filter Preferences

Hang / freeze everything (all in browser) when trying to open and select whatever in AdBlock Plus Filter Preferences window. CPU usage on firefox process jumps at 50% permanently and becomes totally frozen / unresponsive.

I have suspected electrolysis (e10s) in Firefox as source causing the problem. But I see Multiprocess Windows 0/1 (Disabled by add-ons) and electrolysis looks to be disabled.

Could you please help me to solve that issue.
