# SuperchargePerformance 1.5.4 — Shorts Play Again and Tabs Sleep on Time

## YouTube Shorts Play Again

Shorts opened directly, from a link, a new tab, or a reload could show a playback error instead of the video. They now play. Ads in the player are still removed as before.

## Tabs Sleep on Time

Tab suspension counted the time you spent reading a tab as idle time, so a tab you had been reading for a while could be put to sleep seconds after you switched away, and reloaded when you came back. The idle timer now starts when you leave the tab, so it sleeps only after the full interval you chose.

## Fixes & Other Changes

- The ad and tracker blocklists are refreshed from their sources.
- Four sites the security lists blocked by mistake now load: Naver blogs, the "Log in with WeChat" window, and the MetaMask websites.
- The cookie banner auto-reject is updated and now closes the banner on more sites. In our tests it newly handled the BBC and Yle banners, and no tested site got worse.
- No new permissions.
