12 years ago, Firefox wasn't multi process. So your bug would likely freeze the entire browser, including the UI. Considering that, back then, Firefox reloaded all tabs back when you reopened it, it would keep freezing even if you force closed it. Fun times.

I actually kept such an SVG bomb around as a demonstration of how badly you could break browsers for many years, to anyone who claimed they were completely secure and unbreakable.

I should go see what happens if I load it now, since what changed was less that it stopped breaking them and more that I stopped having the conversation with many people...

That was always an option, as I recall. I think a non-default option, too. Not sure when they started adding the question about if you wanted to restore when you started up after a crash/unsafe shutdown.
