• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.

• using a new, unmodified browser profile.

Yes, sorry, this isn't a bug. It's my mistake: I disabled default file manager in Android and this was a problem.
