Could we have some more information please (screenshots would also be great), as I'm not sure what you mean by a page not opening. Do you get taking to a blank page? Does the web address change? Is this when clicking a link or typing an address in? If it is when clicking a link, do you stay on the same page? Is the page supposed to open in a new tab? Is a blank tab created?

Occasionally I have the problem that every page I go to is blank and the address bar is blank, but for me this is due to a bug with Windows 8 (and 8.1) which means my PC doesn't understand the IP address it is being assigned (even though it hasn't changed). I am able to resolve the issue by logging out of my Windows account and logging back on again.

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.
