Answer 1

Here is a good discussion regarding HTML5 Local storage limits HTML5 localStorage size limit for subdomains

Regarding browsers, here is a list,

Firefox 3.5, Safari 4, IE8, Chrome 4+: HTML5 localStorage; these modern browsers all support the core localStorage functionality defined in the HTML5 draft.

Firefox 2.x and 3.0: Gecko globalStorage, a very early implementation similar to HTML5’s localStorage.

Safari 3.1 & 3.2: HTML5 Database Storage, because Safari 3.1 and 3.2 don’t support HTML5 localStorage.

IE6, IE7: userData persistence, a rarely used IE feature for associating string data with an element on a web page and persisting it between pageviews.

Google Chrome Pre 4: Gears Database API, which is built into earlier versions of Chrome and thus doesn’t require a separate install.

Here is alist of browsers that support this functionality. https://stackoverflow.com/questions/1194784/which-browsers-support-html5-offline-storage
