<all_urls>
Yomichan requires access to all URLs in order to run scripts to scan text and show the definitions popup,
request audio for playback and download, and connect with Anki.
-
storage and unlimitedStorage
Yomichan uses storage permissions in order to save extension settings and dictionary data.
unlimitedStorage is used to help prevent web browsers from unexpectedly
deleting dictionary data.
-
webRequest and webRequestBlocking
Yomichan uses these permissions to ensure certain requests have valid and secure headers.
This sometimes involves removing or changing the Origin request header,
as this can be used to fingerprint browser configuration.
-
nativeMessaging
Yomichan has the ability to communicate with an optional native messaging component in order to support
parsing large blocks of Japanese text using
MeCab.
The installation of this component is optional and is not included by default.
-
clipboardWrite
Yomichan supports simulating the Ctrl+C (copy to clipboard) keyboard shortcut
when a definitions popup is open and focused.
-
clipboardRead (optional)
Yomichan supports automatically opening a search window when Japanese text is copied to the clipboard
while the browser is running, depending on how certain settings are configured.
This allows Yomichan to support scanning text from external applications, provided there is a way
to copy text from those applications to the clipboard.
