Can you give us the link you are trying to access?

Also, are you able to access it via Chrome or IE?

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You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.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

• The image "new fx menu" does not exist. > Options/Preferences> Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• The image "new fx menu" does not exist. > Options/Preferences > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

yes with IE i don't have any problem.also i try to open firefox in safe mode(it works fine in the safe mode).i have problems with everything from uploaded.net like this one: http://xtragfx.com/engine/go.php?url=aHR0cDovL3VwbG9hZGVkLm5ldC9maWxlL2FteXY0dXluL3dzeDVfZXZfMTAuMS44LjUyLnJhcg%3D%3D

Huh, if it works fine in Safe Mode, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

• The image "new fx menu" does not exist. > Add-ons > Extensions

ok thank you

Were you able to get it working normally or are you still having issues?

until know yes
