Is tubitv.com Safe?

Although Tubi TV is the best free movie and tv outlet, in my opinion since they have better quality content and a lot more variety, movies, etc. than any other tv outlet, with the exception of Google Movies and TV. There is a security issue, when I first land on the website in my browser the padlock in the web address bar is there indicating a secure website but after signing in and choosing a movie, the padlock has a strike through it, as some point, and say's "not secure". So what happened? Has the Facebook sign-in page caused the security breach? Just recently Tubi TV has implemented the option to sign in with an email address and password and not Facebook I will try this option and update my finding's here soon.

I don't have underage children so that I do not filter "adult" content from any of my sources of information or entertainment. Nudity is a subject that may be personally offensive to some but I find it offensive only if women, men, or children are obviously being exploited for other than an informative purpose, as in a documentary, for example. Also, my response to offensive material is to report it to the website and to not ever to continue supporting it.

I think the person who left a bad rating, doesn't understand what this is. TubiTV is a streaming channel on Roku and Amazon Fire, and this is their website. I use it on my Roku. Plus it seems I can watch the movies/shows streaming on my computer from this site. There were no redirects, no click-and-pay scams, or whatever else that guy was mentioning.
