As more and more sites switch from using cookies to using localStorage to store their data (including "tracking bugs"), I'm concerned about in how far the user can control this. With cookies, one could set up the appropriate policies, e.g. block 3rd party cookies, or being always asked. I could not find a corresponding setting for localStorage.
Searching SU, I found a similar question for Chrome: disable HTML5 LocalStorage and Databases for all webpages /or ask user. I've also read How to allow local storage for one specific userscript, but disable it globally? (which does not answer my question) and Firefox local storage and cache questions (which also states missing documentation, but does not answer my question). I found almost nothing on a Google search.
Trouble I've had in the beginning with SE in general (see MSO) and solved thanks to Eric's Blog let me assume the cookie settings are at least connected to localStorage somehow; but as it's not documented, I don't want to rely on "try-and-err" with one FF version to draw general conclusions from.
Is there some documentation on that? I'd count it a big privacy intrusion if the user cannot control which site is storing data into localStorage, so it must be possible somehow.
