Periodically, the following bug occurs on different phones. I also found it in complaints on google play and I will take the text from there (you do not give a solution to the problem), but I will provide my screenshots. This is not the first time this issue has occurred, on various phones in my family. "I tried using it again, and EVERY website I try to access doesn't load. It just shows a gray screen and the lock in the URL bar is in the "connection is not secure" graphic. I can't even access about :config because it's also just a gray screen.HOWEVER, every other browser on my phone works." It helps to solve problems only by completely deleting all firefox files and then setting it up from scratch. It is unpleasant. On screenshots: the endless loading of the add-ons section and the display of any site.
