Is "add_browser_box" still used ?

[J-oh-n]

Within this file https://github.com/dis-moi/extension/blob/master/src/libs/i18n/resources/fr/profiles.json
line 84, there is an "add_browser_box" which we couldn't identify where it is used on the lememe.fr or dismoi.io websites.
If it is not used anymore, we should remove it to avoid confusion
