Has anyone else had the issue lately where when making a post, it gets posted twice?

I can't tell what's been happening, but it has occurred multiple times recently. I use Firefox, so maybe that's a factor, but I'd also guess Firefox usage per capita is higher than average in the Lemmy crowd.

In at least one case, I pressed the create button, and it appeared to not work, so I pressed it again.

I feel like I should file a bug report, but I first need to do more troubleshooting, but since I can't just go fill a random community with posts trying to reproduce this bug, I should probably set up a test instance. Before I do that, though, I was wondering if anyone else had experienced this problem.
