It wasn't immediately after update. It was after you updated it while it was running and then you tried something, that triggered the crash (like opening a new tab). Later it stopped to crash, but acted weirdly (clicks on links didn't work, etc). Nowadays we have the notice to restart the browser. It didn't arrive years ago, just a few releases ago. This was only under Linux, and only with the distro package managers. Under Windows or MacOS, the updater updates the browser on next restart, so this didn't happen.
