[Closed] Is it me or stw? Redirect issue.

Each morning when I start my browser I have a number of sites I create a tab for. First is calendar (home page) then stw, then some others.

By the time I have all the tabs open the first non-home page one (that I thought was going to be stw) has redirected to this;

I recently had an update to Firefox 54 so when it first appeared I assumed it was a patch but the url looked wrong (not as wrong as the one in this screen shot).

Googling any of the url's it shows always gives zero results in Google (even with a who is which is odd).

Anyway, given I've not clicked on any of these should I worry?

Is it me not being logged in when I open stw that's allowing this to happen (dodgy ad?) or something else?

Sorry mods, wasn't sure whether to tip this into the 'dodgy ads' thread and couldn't find that with a search in any case.
