'''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. [[Template:MixedContent]] __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<!-- -->.org. #*If you can open another site, skip down to [[#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 [[#w_the-problem-only-happens-in-firefox|The problem only happens in Firefox]] #*If the site doesn't work in another browser, check out [[#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} * [[Websites look wrong or appear differently than they should]] * [[Fix problems that cause images to not show]] * [[Fix common audio and video issues]] * [[Websites show a spinning wheel and never finish loading]] * [[Fix login issues on websites that require a username and password]].

See [[Send plugin crash reports to help Mozilla improve Firefox]] for more information. *'''Malicious website errors''' - If you see a "Suspected Attack Site!" or "Suspected Web Forgery!" warning, Firefox has blocked access to the website you're visiting to protect you from [http://en.wikipedia.org/wiki/Malware malware] or [http://en.wikipedia.org/wiki/Phishing web forgery (phishing)]. For more information, see [http://www.mozilla.org/firefox/phishing-protection/ Phishing and Malware Protection (Mozilla.org)]. *'''Offline mode''' - If you see a message about offline mode, you may have set Firefox not to use your network connection. Make sure your computer has a network connection and then: **Click the menu button [[Image:New Fx Menu]], click {button Developer} and make sure {menu Work Offline} is unchecked. *'''The page isn't redirecting properly''' - This problem can be caused by problems with cookies. See [[Websites say cookies are blocked - Unblock them]] for more information. *If you get a '''File not found''' error, try the troubleshooting steps in these articles: ** [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] ** [[Troubleshoot Firefox issues caused by malware]] *'''Content Encoding Error''' - If you get the error message, ''Content Encoding Error'' or '''The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression''', use these steps to diagnose and fix them: *# Check the settings of any Internet security applications you use (including firewalls, anti-virus or anti-spyware programs, and privacy protection programs). You should try to remove any permissions those applications have for Firefox, and then add them again. For program-specific instructions for a number of applications, see [[Configure firewalls so that Firefox can access the Internet]]. *# Follow the [[Troubleshoot and diagnose Firefox problems|Standard troubleshooting steps]]. *'''This address is restricted''' - This error occurs when you are attempting to connect to a web server on a [http://en.wikipedia.org/wiki/Port_%28computer_networking%29 port] that is reserved for another application. If the website you are trying to visit contains a colon followed by a number in its address (for example, ''http://website<!-- -->.com:23''), try removing that portion (''http://website<!-- -->.com'') or replacing it with '':80'' (''http://website<!-- -->.com:80''). If this doesn't work, you may have been given an incorrect address. *'''DNS cache is invalid''' - DNS is the service that converts a website's domain name into the IP address that Firefox uses to connect to a website. This information is saved to your DNS cache in order to improve speeds. However, if the DNS cache record is corrupt or the website has changed IP address, Firefox may be directed to the incorrect server. See the [https://www.whatsmydns.net/flush-dns.html these instructions to flush your DNS]. <!-- MZ credit --> <br/> <br/> '''''Based on information from [http://kb.mozillazine.org/Error_loading_websites Error loading websites (mozillaZine KB)]'''''
