We’ve submitted an update (version 1.5.4) to the Google Extensions web store. The extension is still free. This update will fix some issues some users may experience trying to install 1.5.2. The update is pending Google’s full review and should be released within a few business days, according to the Google Developer center.
This version also includes some new features including page auto-scrollers, better premium content detection and marking on Amazon, YouTube, and other sites, fixes for YouTube corner-video mode, performance improvements and a few other updates that improve features. This includes pausing all side-column-scrollers while in “wide player” video mode to improve performance on slow computers that use multiple media tabs simultaneously.
Check the Google Web store or back here on our blog after a few days to allow time for Google to finish their review get the latest update to 1.5.4.
