Kancolle-Opener is a free Chrome add-on developed by yussy that allows users to access the Kancolle game page without compromising security settings. With this extension, players can connect to the game page using http instead of the default https protocol, even after the latest Chrome update in August 2023.

By simply installing Kancolle-Opener, players can continue enjoying Kancolle without having to make any configuration changes or sacrificing security measures. This extension utilizes a different method than the required bookmarklet for iOS15 and above, ensuring that all features of Kancolle function properly.

Please note that this extension has been tested and verified to work as intended. However, if you encounter any issues, you can reach out to the developer on Twitter (@naayu1012) for assistance.

[Technical Information]

• As of August 28, 2023
• When accessing the game page via https, Kancolle-Opener automatically redirects to the http game page. Please note that this method may be further improved in the future.
