Just had it happen yesterday with the the students loan simulator. It wouldn’t work on Firefox and kept getting hung and freezing. Opened it in chrome and it worked perfectly first time.

It’s not common, but enough that I keep chrome installed for now.

When someone sends me links to instagram on my phone, firefox mobile can't play the thing, I'm forced to open the link in chrome to watch the video. There are lots and lots of websites and webapps that don't work or barely open on firefox. I'm forced to regularly open every week a few links on chrome/chromium on my computer as well. Although the amount as reduced a lot, some years ago it was worse.

I've used several sites that just won't scroll in Firefox. Coursera is awful for this and a lot of job sites seem to use the same library because they have the exact same issue

both are still just chromium and as such still subject to google's bullshittery like amp, manifest v3 and web integrity

It’s still chromium based, which I’m trying to get away from as much as possible.
