Comment 3 Strahinja Kustudic 2020-06-02 06:58:33 UTC

I have the same problem for a few weeks now. It usually happens when there are more tabs loaded, I don't remember it crashing with only one tab.

I'm not 100% sure but I also think that it crashes when the closed tab is not the last. It's not always like this, but that's what I remembered.
