Extensions are grouped by the store's own publisher account ID, so a developer who uses several accounts appears on several pages. Live extensions come first, most users first. | Extension | Category | Users | Rating | Updated | Status | | --- | --- | ---: | ---: | --- | --- | | [Chess Helper (chess.com)](https://extensiontracker.com/extension/klhidcpkkhfcpmjhhikchaikmbefiajf) | Education | 30,000 | 3.72 | 2026-02-16 | Live | | [Language Immersion](https://extensiontracker.com/extension/cacmapfpcpdcgilpfiiheciieiknnlkk) | Education | 56 | – | 2026-02-12 | Live | | [Chess Helper (chess.com)](https://extensiontracker.com/extension/hjckkelojekmgpgnoalgjhibpfcnmlnf) | Entertainment | 25 | – | 2026-10-26 | Live | | [World Cup 2026 — Live](https://extensiontracker.com/extension/hfofanlgfecbpcbnjepgimglfjalidcl) | Entertainment | 12 | – | 2026-06-14 | Live | | [Image Saver Pro](https://extensiontracker.com/extension/leijliihilcajgkgjenifhndlbobjiga) | Tools | 11 | – | 2026-03-02 | Live | --- From Extension Tracker, a public record of the Chrome Web Store: .
