all phone numbers appear hidden when brought up in firefox
Whenever I bring up a site that has a phone number on it, the number flickers for about 1 second and then disappears off the screen - even the line the phone number is on disappears. How do I fix this.

One of your add-ons might be the culprit. Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode with all add-ons disabled. If that solves the problem, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and possibly Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
The Skype extension for Firefox is known to cause phone numbers on web pages to disappear after loading initially - disable that extension.
Also, and although possibly not related to your problem, I have to remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. On top of this, it has known unpatched bugs and security problems. I urge you to update to the latest version of Firefox, for maximum security, stability, performance and usability. You can get it for free, as always, at getfirefox.com.
