Gmail Tab Crashes

[burned]

The Gmail tab causes crashes on every browser I have tried. What can be causing the browser to be soo unstable on Gmail? I have tried Firefox, Chrome, and Brave. All browsers will sooner or later crash the open tab when using Gmail. Windows 10 machine. BTW this only happens on the Gmail page when accessing Telus mail

Are you able to access your Telus email using the Gmail app?

Do you use Norton 360 or other network security program? Have you tried Microsoft Edge?
