@elitoncabral Jumping into this thread randomly, but i did exactly those steps few days ago and it just keeps happening. I drastically reduced the amount of tabs open but doesnt matter how many are there, they will move each time i open the browser.
I noticed that especially when I use RAM/CPU limiter; those also dont work as intended (the tabs in the background wont unload no matter what, causing the memory cap to be hit really fast)
