Translate feature empties forms

I frequently have to toggle on the translate feature to view pages in the country I’m living in. When the translate feature is active, and if I am filling out a web-form, I am unable to leave/minimize the page (say, to go to the notes app to copy and paste an ID number, address, etc), because once I return Firefox blinks and empties the form. I only notice this when translate is on, no other time. So I have to fill out forms in another language or make sure I have all important info literally written on paper to keep from having to leave the app for any reason. Is there a workaround?
