Why can't I see telephone numbers when they are posted on websites (I have tried different websites-it's the same)?

When I'm on a website the phone number posted doesn't show. I thought it was that specific page but it's the same in different web pages. I have to keep refreshing because it shows for less than a second and then it hides and there is not way I can see it unless I keep refreshing it. This just started a month ago because before it didn't use to do that.

I bet is has something to do with the Skype extension you have installed. Go to Tools > Add-ons > Extensions, select the Skype extension, and click Disable, then restart Firefox.
