Steps to reproduce the problem:
Set browser language to Spanish and hover over the back button

What is the expected behavior?
The tooltip text should communicate "Click to go back, or hold [down a mouse button or finger] to see the history"

What went wrong?
The Spanish text says "espera para ver el historial", which means "wait to see the history". Just waiting, of course, does not show the history.

Did this work before? N/A

The description for translators would ideally clarify that here the text means "hold" as in hold down a finger/button, not as in hold on for a second. There might be similar problems in translations other than Spanish.

Forward has the same problem with "hold", and also says "Haz click para continuar" ("Click to continue"), when Forward isn't exactly a "continue" button. Maybe it could say "...para avanzar en el historial"? Just "...para avanzar"? I'm not sure what's right or even what the English text is but presumably the pros can work it out given context.
