Tired of having no way out when you run into a webpage that can not be found? TryAgain, an add-on for Firefox, will give you a few more routes to check when it comes to seeing if a website is really down or not.
This great extension for Firefox will keep trying to reach a webpage even if the server cannot be reached.
You also get a few more tools to try, if you are troubleshooting a website issue of your own, or for somebody else. You can try checking two different uptime checking tools, and also try visiting the website via a proxy service. This should help you troubleshoot if your problem is within your own network or not.
You also have the option to abort the "trying" as the add-on will continue to try to load the page you requested again and again. Just in case you really want to see what that webpage has to offer – you also are given the chance to view it through the WayBack Archive or Google’s most recent cache of the webpage.
While not perfect, TryAgain does give you a few more routes to check when you run into a webpage that can not be seen. You can pick it up from the Mozilla Add-ons website.
