Echofon was great until the Twitter API changed to 1.1. The developers discontinued support for it as well leaving all of us with the Echofon client in the dark. Someone has been able to patch it up though, and today I’ll show you how to get your Echofon back.
Download the latest patched version of Echofon. The latest one should be “8”. Afterwards, navigate to your Extensions page. Go to the Firefox menu, then select Add-ons. In the Add-ons window, click Extensions. You could also press Ctrl+Shift+A. Then, you select “Install add-on from file…”
After that, find the file you just downloaded and install it. Restart Firefox and you will have Echofon again!
