If i go to Tools > Addons and click on the "Check to see if your plugins are up to date" link, it gives me an error "Plugin Finding Service Error We've encountered an error. Please try your request again later." The link is sending me to https://www.mozilla.org/en-US/plugincheck/ If i manually navigate to http://www.mozilla.org/en-US/plugincheck/ it works fine. Therefore the link to the secure protocol has broken thanks. ..
