What is the 'Google' translate tool? If you want to disable the new Firefox translation, change the value of this preference to false : browser.translations.enable

If you only want to stop the pop-ups, changing the following to false may work. browser.translations.automaticallyPopup

It says "google translate" which is shown in the screenshot i added. I did change all those values to false but still it pops up on certain sites like Wikipedia etc.

There is an extension to google translate; there may be similar extensions. Do you have one of them?

No. That's why im so surprised to see it. And from what i can find there is no way to turn it off which sucks! I want it gone and i have tried to check my extensions, sett all the values to "false" and checked the settings in firefox.

Try installing the No Google Search Translation extension.
