I find Firefox Translator doesn’t pick up a lot of pages. The location bar button doesn’t appear.

It works if I access via the hamburger menu. It is very slow to have to go via the menu for each individual page. I find no shortcut key or anything.

Sometimes this will correctly guess the original language but often not. It is saying pages are English even when they have little to no english, even using different alphabets.

Is there something the website admins can do to tell firefox what language it is? Encoding? Meta tag?

Can I force the location-bar translate button to persist on all pages regardless of what language it thinks the page is in? Then I could save going through the menu.
