Description of the issue:
On my browser, new home1.ultrasurfing.com tabs keep opening up. Multiple times, multiple tabs.
How can this issue be reproduced?
Haven’t figured out what the cause is yet, nor can I find any pattern…
Expected result:
Brave Version( check About Brave):
1.23.71 Chromium 90.0.4430.72 Official Build x86_64
Additional Information:
Hi there @Christine.minju.kim, welcome to community 
Can you try disabling all of your extensions? If that solves the problem, the next steps would be to enable each extension one by one, and seeing which one causes the issue.
Best,

Thanks, Sally! Ultrasurf had sneakily installed an extension - all solved now!
Happy to hear that your issue was resolved!
Thank you for using brave and feel free to post anything on community if you run into any issues in the future.
Have a great weekend.
All the best,
Salty
