I unfortunately do not have a running list. The one that made me drop Firefox last time was the mermaid.js docs site. None of the sidebar navigation was clickable but only on Firefox, the same issue did not appear on Safari or Chrome. It appears they have since fixed that issue as I retested and it appears fine.

The "give me examples" is sort of a moving target, anecdotally I have run into many more completely or partially broken sites when using Firefox as compared to Chrome and Safari. It is likely that some or all of those examples are now fixed but the pain in the moment is enough to keep me from using the browser long term.

Is it this site? https://mermaid.js.org/intro/

It works fine for me.

Often people forgot they have installed an obscure exstension in Firefox and that is breaking the site, trying another browser it works, concluding that Firefox must be the problem, while it was the extension. That is also why people usually cannot reproduce the problem later or give concrete examples.
