Problem accessing certain blogs. :(

I suddenly have a problem accessing some of my favourite blogs. I get this message, and it will go no further:

I don’t know whether it’s problem with WordPress or my web browser. I’m using Firefox on an Apple Macbook Air. Have any of you had similar problems, or can you please give me some advice? Thanks so much. 🙂
