Firefox occasionally opens advertisements tabs

Occasionally (maybe few times a day) Firefox opens a tab that contains advertisements after maybe about a minute entering a website. This appears to happen in any website (for example, youtube). The tabs itself aren't very annoying, but I'm worried that it's caused by a virus or similar.

I've tried so far to: -delete all cookies -scan the whole computer with Avast -scan whole computer with Malwarebytes -scan the computer with Malwarebytes Anti-Rootkit -scan the computer with Kaspersky TDSSKiller

(ps. there was no indication about which language to use, so I typed in english, even though my interface is in finnish.)

Well that's the way of least effort. If the problem reappears please check the linked thread. Some of the possible causes mentioned there might explain the problem disappearing seemingly by itself. For example, tabs may be opened by a page that's open in some tab in Firefox.

A moment ago a new tab opened again. By looking at the browsing history, it first opened link to https://lzpv4rsmat.com/h159kp2r?key=811a4a1d4729a23a23030d82c812ae77 from where it redirected it to https://welcome.unibet.com/fi/prog/sportsbook/football/world-cup/2018/index.html?mktid=1:127656177:28403482-30884
