For a month or so after last updates is getting impossible to work with firefox. It's is getting sluggish with 3-4 open tabs after few minutes, I can't do anything, have to close all windows and open again. Even to text this for got ridiculous slow, I have only 5 addons enabled, I had 10 before but for testing disabled all others. now only have ublock origin, disconect, ad-block, blocktube, and facebook container. If I open youtube, facebook and a google searching page and start to use, after few minutes everything goes very very slow, if to type something. What's going on ? Also there's like 12 firefox tabs on task manager, taking a lot of processing and memory. Already scanned with antivirus, and it's clean. Intel i7-6700T 16gb ram, SSD, Radeon R7-M370 it's a HP AIO 27-p010xt-CTO. And is not because it's an old machine on my new laptop happens the same, and I went online and there's a lot of people saying the same.
