Problems opening some apps when Firefox for Android is the default browser

I have a Samsung Galaxy Z Flip5 and use Firefox as my default browser (only extensions are uBlock Origin and Bitwarden); I also have DuckDuckGo running App Tracking Protection in the background for non-browser tracking. Some apps (like Wells Fargo, but also a few others) fail to fully load when Firefox is my default -- I switch to Samsung Internet (with AdBlock) and the same apps load fine. I've tried changing Firefox from Strict to Standard Enhanced Tracking Protection. Any other recommended troubleshooting steps? Thanks so much.

Hi

As an experiment, what happens when your turn off enhanced tracking protection in Firefox for Android and remove all add-ons?

Thanks for the suggestion. I'll try it the next time it happens!
