Although the size of localStorage has been addressed in detail and there is a online test for it, I was wondering what the maximum size of sessionStorage is for the common browsers?
回答1:
According to this site, Firefox’s and Safari’s storage limit is 5MB per domain, Internet Explorer’s limit is 10 MB per domain.
However, according to this site which tests your web browser local storage capabilities, on my machine:
Browser LocalStorage SessionStorage
------- ------------ --------------
Chrome 5M 5M
Firefox 5M Unlimited
IE11 5M 5M
Also, note the handy chart at the bottom of the page.

The amount able to be stored varries from browser to browser with IE being able to store up to a couple MB. It is also good to note that there is a vulnerabilty that allows an unlimited amount of data to be stored.
