'''Are you having trouble getting a website to load?''' Don't worry — we're here to help. This article will show you how to fix the problem so you can get back to surfing the web. __TOC__ =First, let's figure out where the problem is= ''With a little detective work, we can narrow down the cause of the problem.'' #Open a new tab and check to see if you can load another website like google<!-- -->.com or mozilla<!-- -->.com. #*If you can open another site, skip down to [[Error loading web sites#w_the-problem-only-happens-with-certain-websites|The problem only happens with certain websites]] #*If you can't open another site, continue on to the next step. #Launch another browser, like {for win}Internet Explorer{/for}{for mac}Safari{/for}{for linux}Google Chrome{/for}, and try to open the site you were having problems with. #*If the site works in another browser, see [[Error loading web sites#w_the-problem-only-happens-in-firefox|The problem only happens in Firefox]] #*If the site doesn't work in another browser, check out [[Error loading web sites#w_the-problem-happens-in-all-web-browsers|The problem happens in all web browsers]] =The problem only happens with certain websites = If you see any of these error messages, it might just be a problem with Firefox's cache: * '''The connection was interrupted''' * '''The connection was reset''' * '''The connection has timed out''' ==Try clearing Firefox's cookies and cache== ''Do these steps and then reload the website you're having trouble with.'' [[T:clearCookiesCache]] If clearing Firefox's cookies and cache didn't work, it's probably a sign that there is a problem with the website itself. In that case you'll just have to wait for it to get fixed. With big sites like Twitter or Facebook this may only be a few minutes. '''If you don't see any of the error messages above, check to see if any of the specific problems below match what you see:''' == The website loads but doesn't work properly == If the website doesn't look right or doesn't work the way it's supposed to, you should check out the following articles: {for win} * [[Warning Unresponsive script]] * [[Websites look wrong|The web page just doesn't look right]] * [[Images or animations do not show]] * [[Video or audio does not play]] * [[Firefox never finishes loading certain websites]] * [[Cannot log in to websites]].
