This is certainly a very nice feature. A GUI would be needed in the settings manager so that the target languages could be set better. For example, I from Germany with German as my native language would like two languages: - English - German
So the simplest solution is certainly to set a primary language in the Settings Manager.
This should be freely adjustable because, for example, the Firefox beta is only US and you would get an incorrect entry.
It will be very useful to have the possibility to use the right click on a website page to have translate the page in your language preference. Like you in the other navigator chrome, edge...ect . Because now you need to go on the adress bar click on the translate icon and click on translate the page but it will be faster if you just have the right click like also other translator extension in firefox. It will be very usefull to have that for the official firefox translator.
Right-Click Context Menu: Translate to <default language>
The reason why it's needed is that Translations automatic detection doesn't work all the time. For example, Twitch streams with languages other than English. In those cases I have to go up to the hamburger menu in the top right, select 'Translate page...' and manually select both languages.
Translation is an essential feature for non-English speakers, and I am very grateful that it is being addressed.
It is a bit of a hassle to bring the cursor to the address bar every time you want to use a translation. I would like to be able to use the translation of the entire page from the right click.
1) From the Firefox main menu, there is a menu item to trigger translation.
2) Select text, right click, select the menu item to translate the selection, then from the translation dialog that shows up you can click "Translate full page".
