I've been fighting the Firefox good fight for years. Always stuck by it. Spent so much time looking up the text area issue (happens during cut/copy/paste). Still stuck with it. But the export (been doing exports since Netscape, it's not complicated) issue was enough.

So nope, not from my end.

And I jump from chrome and edge on my pc now. They're all chromium based anyways.

Still use Firefox as my default android browser though.
