I think its time to move on from Firefox as this browser has been ruined by multiple LEACHING OF MY RAM processes!! Ridicules that I have 1 tab opened right now and 19 firefox processes!!! WTH is with this crap and why have you now taken away the :about preferences: work around?...you have ruined this browser to where I need to lose it!!
From last years my browser Firefox continuously does the same: for a few tabs, with low operation in addition, it opens a multiplicity of process with exaggerated and inexplicable resources consumption, tending to occupy all existing capacity.
It would be interesting to know the reasons.
