Explainer https://github.com/explainers-by-googlers/static-storage-quota Specification No information provided Summary Fixes a bug in the predictable-storage-quota that allows Incognito mode to be detected. A change introduced recently to Stable, buckets the result of the StorageManager's estimate API for sites that do not have unlimited storage permission to max(10Gib, ceil(actual_quota_in_Gib)) + usage. However, in incognito mode, the actual quota value is based on a fraction of available RAM, instead of the disk space - providing an Incognito detection surface. This change fixes the value of this API for Incognito Mode to the maximal bucket of: usage + 10Gib. Discussion on the original feature available here: https://groups.google.com/a/chromium.org/g/blink-dev/c/7q0YGQNVkjs/m/mpYkQVWpAQAJ This is a new Chromestatus in place of an original PSA, as this launch should start with an I2E to ensure the breakage risk is properly addressed.
