Tumblr

Social ·Javier Negrete · checked

Tumblr was a Chrome App, not an extension, and Chrome no longer runs it. It was a launcher that opened dapper131.tumblr.com in a tab, so it never reached any more of your browsing than a bookmark would.

Its last update was 10 years ago. The site it opened is a separate thing from the app that opened it.

What this was, and where it went

Tumblr was a hosted Chrome App: a launcher that opened dapper131.tumblr.com in a tab. It was not an extension and it was not code running inside your browser — it could reach no more of your browsing than a bookmark to the same address.

Chrome Apps were a separate platform, and Google withdrew it. Support ended on Windows, macOS and Linux in 2022 and on ChromeOS in early 2025, so the launcher no longer starts. That is a different story from the Manifest V2 wind-down, which is about extensions and happened later.

The address it opened was dapper131.tumblr.com. It no longer serves a page: we requested it on and the server answered 403. So both halves of this one are gone, the launcher and the site it launched.

Its listing was still in the store when we checked on 1 September 2026. Being listed and being usable are different things, and the store does not distinguish them.
