If you are a developer and something about your extension is wrong
Write in and it gets fixed. Every figure on an extension's page is read either from its manifest or from its public store listing, so if something is inaccurate it is either a parsing bug on our side or stale data, and both are worth knowing about.
If you would rather your extension were not listed at all, say so and it will be removed. Please include the extension id, which is the 32-letter string in its store URL.
If the extractor failed on a file
Tell us which extension it was. The interesting cases are packages that are not CRX3, ones large enough to exhaust memory in the browser, and anything where the resulting archive will not open.
If a page is missing or wrong
Send the URL. Corrections to the permission descriptions are especially welcome — they are written by hand, and Chrome's extension platform keeps moving.
