Basically, what it says in the title. Not so long time ago I started noticing that Firefox starts randomly "freezing" when switching between tabs (most often) and clicking on links within webpages. I put "freezing" in quotation marks, because it's not really frozen - I can click on the tab and interface would respond, but showing new tab wouldn't happen. I made a video and shared it on Google Drive. https://drive.google.com/file/d/1IBVhYru58l5xlfkz7GrvYuscWqCoC_gH/view?usp=sharing Few things to consider: 1) Bug present in both latest stable and beta versions 2) Bug still present in completely clean installation of Firefox, without any add-ons and not signed-in in the account 3) I use v2ray and Qv2ray to bypass internet restrictions of a country where I am currently at. It seems that "freezing" has to do with poor internet connection. Has anyone encountered similar problems?
