I've seen this dialog (the misleading "[OPEN] [CONTINUE]" one) on mobile Firefox as well. Besides that you have the pulsating "open in the app" at the top of every page.
Fortunately I have u-block origin so I could just add a few filters to get rid of that nonsense. It doesn't solve the terrible performance however (because apparently you need a top-of-the-line smartphone to load and display a few kB of plaintext comments).
