Great because there is option to open in new tab Bewertet mit 5 von 5 Sternen
Unlike some other Google translation addons this one has a setting to "Open translations in new tab". I do not like covering up the page I am trying to translate.
The "About this Add-on" info needs to be updated to indicate that "no restart" is only for initiating translation via the context menu. To get the translation button to work one has to restart Firefox. Then the translation button works.
