艦これNoBack is a free Chrome add-on developed by anji.dev. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This program aims to prevent accidental page navigation, such as browser back or reload, while playing Kantai Collection.

During gameplay, it is common for players to accidentally click the back button or reload the page, which can lead to frustration and loss of progress. With 艦これNoBack, this issue is addressed by displaying a warning pop-up whenever the user attempts to navigate away from the game page.

It is important to note that 艦これNoBack is not an official tool and the developer, anji.dev, does not take responsibility for any troubles that may arise from its usage. However, for Kantai Collection players who want to avoid accidental page navigation, this add-on provides a useful solution.
