Invisible "text cursor". (The mouse cursor is visible)
After update to 79.0 version, (on Win 7), the cursor totally disappear, an so it's really unconfotable to identify what I'm doing... Now it's possible to identify the cursor position only selecting some caracter, using mouse or case key + arrow. I tried to find some question on the web, and founded to set something in the "about:config" system, but in my list, for example, don't appear the "ui.caretWidth" row. I saw this problem appeared in 2017 too. (It appear NOW, for me...) I don't think to be the last person to use win 7... Can someone helps me?
