Replay browser errors on a dialog element / showing modal about gecko-dev

[markerikson]

Hey, thanks for filing this. My first guess is that this could be due to our Replay+Firefox fork being based on an older version of Firefox that does not have support for <dialog> and its methods. I don't know exactly which version of FF we're currently based off of, but per https://caniuse.com/?search=dialog it looks like Firefox only added support for <dialog> in FF98. It's possible we might be based on an earlier version atm.

I know the Runtime team is primarily focused on building out our Chrome support, with a goal of making Replay+Chrome our primary recording browser over the next few months. That does mean that we're generally de-prioritizing Gecko changes right now.

I'll check further with the Runtime team and see if we can give you an update on all that.

👍 I saw this as well, and thought its possible the fork is old since firefox only semi-recently supported dialog.

In the meanwhile, I'm going to move this issue to the correct repo.
