'''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 win10} or Microsoft Edge{/for}{/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]].

Does it start with '''https://''' (notice the "'''s'''")? If so, check if you see one of the following error messages: *For a "Warning: Potential Security Risk Ahead" error page, see the articles [[What do the security warning codes mean?]] and [[How to troubleshoot security error codes on secure websites]]. *For a "Secure Connection Failed" or "Did Not Connect: Potential Security Issue" error page, see [[Secure connection failed and Firefox did not connect]]. *For a "Your Computer Clock is Wrong" error page, see [[How to troubleshoot time related errors on secure websites]]. =The problem only happens in Firefox= If another web browser works just fine, one of following solutions should fix things: *[[Firefox can't load websites but other browsers can]] - if you can view websites in browsers other than Firefox. *[[Fix problems connecting to websites after updating Firefox]] - if you experience connection problems after updating Firefox. If you see the following error messages, Firefox is trying to access the Internet through a [http://en.wikipedia.org/wiki/Proxy_server proxy server]: *'''The proxy server is refusing connections''' *'''Unable to find the proxy server''' {for win}If you connect to the Internet through a proxy, compare Firefox's settings to Internet Explorer's — see [https://docs.microsoft.com/en-us/internet-explorer/ie11-deploy-guide/auto-configuration-and-auto-proxy-problems-with-ie11 Microsoft's guide to proxy settings].{/for}{for mac}See [https://support.apple.com/guide/mac-help/mchlp2591/mac Enter proxy server settings on Mac] at Apple Support for more information on proxy settings.{/for} To check your [[Connection settings in Firefox|connection settings in Firefox]]: #[[T:optionspreferences]] #In the {menu General} panel, go down to the '''Network Settings''' section. #Click {button Settings…}.

See [[Firefox and other browsers can't load websites]] for some troubleshooting suggestions. =Other, less common problems= *'''A website reports that Firefox is outdated, incompatible or not supported''' - see [[How to reset the default user agent on Firefox]]. *'''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.

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 computer's 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. The [[Firefox and other browsers can't load websites#w_dns-cache]] article explains how to flush the DNS cache.
