Firefox keep saying that known websites are not available - why?
When I go to certain website like Alternet.org, Mozilla responds with a message that that web address can't be found or accessed, so I then have to reboot the website and eventually it loads. What is going on here?

This could be a DNS issue. DNS tells the browser what server runs the website. This information is cached on your system for a while so that it doesn't have to be looked up again.
To clear the DNS cache, do the following:
- Close Firefox
- Press the Windows Key + R
- Run
cmd - Type
ipconfig /flushdns - Press enter
Now if you reopen Firefox, it will have to lookup the DNS for each website. In some cases, you may need to restart your computer for the changes to take effect.

Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).
Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.
