Is Librewolf safe?

I'm quite familiar with the product and have used it for quite a while and know the basics of what it does and how it does it. I really like it function wise as it seems to really block a lot of data broker type issues. My question is that on the chocolatey website it does scanning of new versions and Librewolf always has 5 or less issues in their safety scan. A link about the details takes you to totalvirus and the technical discussions there are simply above me. The whole idea of open-source is great but unless your an advanced code reader its difficult to tell if these are non issues or something to avoid? Who has the time/interest to take a look? Thanks
