Hi Ally, the way the first add-on works is by injecting the Google Translate "widget" into the page. This is a script hosted on Google's site and not included with the add-on.

Mozilla recently decided to block add-ons that inject outside scripts into page. This is because the Mozilla Add-ons team can't trust that such scripts will remain unchanged, potentially turning a safe add-on into a dangerous one.

If you need that "in page" translation to work, a partial workaround is to use one of the userscript extensions (Tampermonkey or Violentmonkey) and a userscript to inject Google's script. I posted such a userscript over here:

It doesn't work on every page because some sites block external scripts using Content Security Policy (CSP). (In that case, the inject menu items won't appear.)

jscher2000,

Thanks for the help n sorry for my late respond...i basically given up hope for google translate to work like a charm in Firefox. I use FF for non-translation-needed sites. Google always a sneaky bastard.

Rgds, Ally

Note that you can also use the Google Translate bookmarklet, what should work on all web pages. If you need a different language then replace google.com by the localized domain.
