[Android Q&A, Help & Troubleshooting] adimrf:
My phone: Xperia 1

OS: Android 9 (updated with latest update from Sony)

Today I woke up with my Firefox (default browser) showing this 3 ad links (which was automatically opened during my sleep):

I have this problem where my firefox suddenly opens weird links like sworkout.club or cryptocurrencytopnews.com while I am busy opening reddit / general browsing, playing games (do not disturb), and even during my sleep.

When it opens, my window directly switches to that page as if it is an Ad.

It happens maybe once few weeks ago but it happens almost every day and during my sleep.

What I have done:

I did use Malwarebytes, Avira, and Avast antivirus but none of them show potential risks.

I reinstalled Firefox, it didn't work. I reinstall ublock (the only add on I added myself) also this did not work.

Do you know what happens?

Can you help me diagnose and solve this?

Thanks in advance!
