So. JS-bloated web pages have crashed my computer 3 times now. (I'm back on my small but plenty beefy Ubuntu desktop now.)
1. Notion running in Firefox
2. Notion running in Brave
I believe both of these were while trying to edit a metadata value on a page.
3. ADPList, just loading a page
I guess I will start by googling why it is crashing my entire computer and not just the browser(s). Both are installed through the snap store, so in theory are sandboxed (or whatever?)
