This CL does the following: - removes sharedStorage.get() from a FF - removes the related permission policy - removes the related attestation category and checks Follow up CLs will remove disableUntrustedNetwork and fence.notifyEvent APIs introduced for FSR. Fenced Storage Read's "do not launch" status announcement: https://privacysandbox.google.com/overview/status sharedStorage.get() in FFs is gated behind a default disabled feature flag and it was never enabled, so this CL does not impact any launched behavior. flag: https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/common/features.cc;drc=f79a5eea7a342c492253d84aa68d44513fa84ef4;l=750 gate: https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/modules/shared_storage/shared_storage.cc;drc=f79a5eea7a342c492253d84aa68d44513fa84ef4;l=765 checked the changes in this CL against the following original CLs: - https://chromium-review.googlesource.com/c/chromium/src/+/5966637 - https://chromium-review.googlesource.com/c/chromium/src/+/5279221 - https://chromium-review.googlesource.com/c/chromium/src/+/5920994 Change-Id: Iedcd065280b56ed86dbc4317e3221cbc00da1e15 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7709973 Commit-Queue: Shivani Sharma <shivanisha@chromium.org> Reviewed-by: Andrey Kosyakov <caseq@chromium.org> Reviewed-by: Mike West <mkwst@chromium.org> Reviewed-by: Alex Moshchuk <alexmos@chromium.org> Reviewed-by: Fiona Macintosh <fmacintosh@google.com> Reviewed-by: Xiaochen Zhou <xiaochenzh@chromium.org> Reviewed-by: Mike Taylor <miketaylr@chromium.org> Reviewed-by: Maks Orlovich <morlovich@chromium.org> Reviewed-by: Yao Xiao <yaoxia@chromium.org> Reviewed-by: Ian Clelland <iclelland@chromium.org> Reviewed-by: Andrew Verge <averge@chromium.org> Cr-Commit-Position: refs/heads/main@{#1609227}
