Hi the names Psyche,
Been using OperaGX since last year. Recently like 3 days ago i start to notice that i am having trouble opening a tab, it keeps closing like automatically once i open a new tab with the plus icon or the simple ctrl + t it automatically closes. Though i found a way to open new tabs without it getting closed by opening the GX corner i can open a tab without it getting closed. (and also just now just found out that it happens when currently im on the tab of facebook like anything facebook connected to the site, but once i switch tab like youtube i can then again open new tab without it getting closed.)
