For some reason my PC had stopped opening links in a browser when I clicked them, so I had to
copy and
paste links into Firefox. So I was trying to sort it out. I looked on the www, then I looked again, looked again etc. In the end I was on a page and there was a
click to see if Firefox is the default browser button, I thought "Why not?" clicked it and it said "No, wanna connect it?" so I obviously clicked yes and now it works. It has been broken for days
