JA/EN Url Toggler

Toggle language code (ja-JP/en-US) in current URL by one click.

JA/EN Url Toggler is a handy tool that allows users to effortlessly switch the language code in their current URL between Japanese (ja-JP/ja) and English (en-US/en). This is particularly useful when viewing pages that may have poorly translated content or when a page is displayed in an unintended language. Please note that this extension will only function if the URL contains a language code, and it has been confirmed to work on the MDN and Microsoft technical documentation pages.
