Can you tell whether the problem is with the built-in feature -- pictured in the following article -- or is it a different feature that could be provided by an add-on?

Firefox Translation

Hey! Thanks for the reply

No it's not an add-on, I have no add-ons with google translate nor plugins. I deleted even ones that were there already and it's still pops up every now and then for no apparent reason

I understand your frustration. You might also try clearing your browser cache and cookies or checking for any extensions that could be interfering. Sometimes, restarting your browser or reinstalling it can help resolve persistent issues.

How does this manifest? Do you see a toolbar at the top of the page? In that case this might be a feature offered by the website and you would need a content blocking extensions like uBlock Origin to hide it.

The Firefox Web Translation feature works differently.

• https://support.mozilla.org/en-US/kb/website-translation

The main translation feature is controlled by this pref.

• browser.translations.enable => true or false

Opening the translation pop-up panel is controlled by this pref.

• browser.translations.automaticallyPopup => true or false

The feature to translate selected text is controlled by this pref.

• browser.translations.select.enable => true or false

Note that you do not get the translation icon for pages that are in the preferred language for displaying pages list, in this case use the "3-bar" Firefox menu button.
