Hi, and thank you for asking your question.
When did you first start having these issues with Edge?
May I set up a quick, secure remote session to check the issue now?
Please reply back to me below. Thank you.
First off, please open up any webpage that shows up the small font/text, and then press the CTRL and 0 (zero) key together on your keyboard - this should reset the default text size accordingly.
Regarding the Favorites, are they missing when you click on the Favorites icon at the top?
Please let me know. Thank you.
