1777653 - localStorage throws exception

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Steve Cooper]

Attachment: localStorage.html

I called:

const value = localStorage.getItem('foo');

Firefox 102 throws an exception rather than returning null. Previous versions of Firefox work as expected. localStorage.setItem() also throws.

I tried starting Firefox in safe mode (all extensions disabled), as well as clearing all cache, local storage, offline data, cookies, etc. Nothing helped.

Some public websites (tumblr, facebook, newtumbl) appear to be affected as well, causing these sites to fail to load correctly.

See attached file for a sample.

Doing a full "refresh" on Firefox solved the problem.
