@jdatapple I don't seem to be able to find any Apple documentation that confirms this. The information on Review your web extension API usage seems to suggest that unlimited grants unlimited storage.

The storage.session API is distinct from the storage.local (and storage.sync and storage.managed) APIs. They have different storage backends and different quotas.
Safari has shipped, with 10 MB as a quota. This is noteworthy because the only other implementation (Chromium) used to have 1 MB as a limit.
Recently, there was consensus among browsers to bump the limit from 1 MB to 10 MB: w3c/webextensions#350
So I suggest the following:
- Remove the
notesfrom Safari. - Modify the
chromesupport to note that before 112, the limit was 1 MB. (starting from Chrome 112, the limit is 10 MB).
Update mdn/content at https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/storage/session to correct the statement about the quota (it currently states 1 MB).
Reference for Chrome bug that bumped the limit to 10 MB:

I also submitted a PR for the content changes on MDN. See #24853.

Does Safari support the setAccessLevel method? See https://bugzilla.mozilla.org/show_bug.cgi?id=1724754#c1 and mdn/content#24873
