Thank you for the feedback jlese. I am a fulltime Firefox user! So, oddly the entire app is built using Firefox primarily. What glitches are you seeing?

Side note to all in this thread: There are definite issues on iOS 13 on iPhone and iPad that we already are working on for the next point release. Examples include a weird bar that shows up at the top of iPad in landscape mode, and on iPhone the search bar doesn't show up. These issues started with iOS 13 I believe. These will be addressed very soon!

The strange thing is that it works fine in Safari. Usually the other way around

Came here to post the same thing. And honestly, it's a bit sloppy to release without checking, given how trivial it is to open an alternative browser.
