Slow down after click
After opening several tabs and then clicking in some weird way that made the mouse change into an up and down arrow, the browser became extremely slow and unresponsive. When I closed the browser and started it again, instead of re-loading all the tabs like it normally does, it didn't have any tabs saved. This may help you diagnose this problem. I have a strange habit of clicking around a lot on websites in areas that don't contain anything clickable. Sometimes I am clicking and dragging over text I am reading as if I need it to be highlighted for by brain to scan it haha. Because I click so much, sometimes I do a right click by accident or I might do strange things like right click and then very quickly left click by accident. When this happened, it seemed like I did one of those click two mouse buttons in rapid succession things. My mouse only has a left button, right button, and middle scroll wheel button. A while back when I was trying out Vivaldi, I noticed clicking around like this frequently caused stability problems especially if a video was playing. This time I don't think any videos were playing.
