-it happens with specific websites like; stackoverflow, github
-most of the time they open normally but i came across this a lot those days
-they open normally when i open the same link on the incognito mode
Thank you for reaching out.
Given that these sites open when viewed in a Private browsing window, I suspect that one of your installed extensions is causing a conflict with the site that results in the blank page. To confirm this, please try disabling all your extensions and test to see if the site(s) appear as expected. If so, re-enable your extensions one at a time and retest until you find the offending extension.
Let me know what you find out.
