Firefox opens tab and types on its own

I'm currently experiencing a something when using Firefox. Every so often a tab will open and begin typing on its own. I've scanned my PC with AVG and Malwarebytes but they showed no infections.

Is it happening only in Firefox?

So far, yes.

Can you check extensions in Firefox and remove/disable unknown ones?

Done. Still have the same symptoms though.

I don't know what else can it be. When something is happening in only one browser then it is tied to its settings or some malicious extension. Try to reset Firefox or reinstall. I do not see active infection in your logs.
