Memory leak Firefox 54.0

[somethingwrong]

Hi guys,

I am using AdBlock on the latest Firefox on a Windows 10 Pro 64-Bit System.
The problem I have noticed is that since a few days Firefox consumes too much RAM to an extent that I couldn't use my browser anymore.
After a short investigation I found out that it was caused by AdBlock. When I activate Adblock my RAM usage of Firefox goes from 400MB to 900MB.
When I turn it off my RAM usage decreases significantly.

I hope you can help. Please fix this.

Come on! This is a serious issue. Not something you can just say nothing about.
