Suspicious activity when importing passwords from Edge to Firefox

Earlier today I was having some problems with my Edge browser not loading a YouTube video beyond 1 minute and 4 seconds into the video so I decided to swap over to Firefox. When I was setting up Firefox I chose the option to import my saved passwords from the Edge browser and not even 1 second later Norton 360 notified me of an intrusion attempt. There were actually 2, 1 second apart.

The timing of the alert has me paranoid because I did get a virus back in December that stole all of my saved passwords from Google Chrome. I used a USB stick and another computer to completely wipe the hard drives and install a fresh Windows after that so I would like to think that I removed it all. I even chose not to back up any of my old files and start from square 1 just to be sure.

I did make sure that I downloaded Firefox from the appropriate website because the virus I got back in December was from a fake MSI Afterburner website that Google listed as the 1st search result as an ad and I wasn’t paying much attention.

So why was my Firefox involved in this sketchy behavior before Firefox was even finished with the initialization process?

If anyone has any ideas about this or knows of a more appropriate subreddit to post this to, please let me know.
