微博扩展插件 is a free Chrome add-on developed by erikloo310. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This extension offers a range of useful features that enhance the user experience on Weibo, a popular social media platform in China.

With 微博扩展插件, users can still view the profile of someone who has blocked them. This feature allows users to stay updated on the activities of their contacts even if they have been blocked. Additionally, the extension enables users to batch block users who have liked a particular comment, as well as remove advertisements from their timeline.

Another notable feature of 微博扩展插件 is the ability to backup Weibo posts, both one's own and others', locally. This includes support for backing up images, videos, and reposts. The extension also allows users to download videos directly from Weibo. Furthermore, the extension supports backing up favorited Weibo posts and displaying exclusive images for vplus members.

Overall, 微博扩展插件 is a powerful tool for Weibo users, providing them with added functionality and convenience. It is worth noting that the backup feature is currently in HTML format, with each backup stored as a zip file containing 100 posts. The extension also supports experimental functionality for vplus member images, which may be subject to change or closure.
