Local Storage Solutions
Solution 1 - Local Storage
##Firefox
Firefox stores localstorage in webappsstore.sqlite
file in the profile folder.
###Firefox (Windows XP):
C:\Documents and Settings\<Windows login/user name>\Application Data\Mozilla\Firefox\Profiles\<profile folder>\webappsstore.sqlite
###Firefox (Windows Vista and above):
C:\Users\<Windows login/user name>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile folder>\webappsstore.sqlite
or:
%APPDATA%\Mozilla\Firefox\Profiles\<profile folder>\webappsstore.sqlite
###Firefox on linux:
~/.mozilla/firefox/<profile folder>/webappsstore.sqlite
###Firefox on mac:
~/Library/Application Support/Firefox/Profiles/
or:
~/Library/Mozilla/Firefox/Profiles/<profile folder>/webappsstore.sqlite
##Chrome
Chrome stores in separate files inside the Local Storage
directory.
###Chrome on windows:
%LocalAppData%\Google\Chrome\User Data\Default\Local Storage\
###Chrome on linux: ~/.config/google-chrome/Default/Local Storage/
###Chrome on mac:
~/Library/Application Support/Google/Chrome/
~/Library/Application Support/Google/Chrome/Default/Local Storage/
##Internet explorer: I am a bit unsure, but think this will do the trick
%userprofile%\AppData\LocalLow\Microsoft\Internet Explorer\DOMStorage
##Opera As said by OammieR:
C:\Users\Administrator\AppData\Roaming\Opera\Opera\sessions\autosave.win
or as said by Kevin Hakanson:
C:\Users\Administrator\AppData\Local\Opera\Opera\pstorage\

Solution 2 - Local Storage
LcalStorage and Session storage are stored as per the browser specific paths (like we have for Cookies)....Also it is kind of limited to the Sandboxed environment of the application. So, only the domain which sets them can read or access it.
Again also remember that only the user has control over expiry of these storage.

I found this (Opera)
C:\Users\Administrator\AppData\Roaming\Opera\Opera\sessions\autosave.win
and another from
Solution 4 - Local Storage
The data for Opera (version 12.14 on Windows 7) was located under
C:\Users\Administrator\AppData\Local\Opera\Opera\pstorage\
A psindex.dat
contained the index to the actual data files. I visited TodoMVC and the quirksmode HTML5 Test - storage to get data saved.

The quirksmode test page let you interactively use the localstorage APIs, so I effectively executed the following code:
localStorage.setItem('Name','Value');
For Firefox see Where does firefox store javascript/HTML localStorage? and for Chrome see How is HTML5 WebStorage data physically stored?.
Opera seems to base64 encode the JavaScript unicode strings in the pstorage\00\0F\00000000
file.
<ws>
<e><k>TgBhAG0AZQA=</k>
<v>VgBhAGwAdQBlAA==</v></e>
</ws>
Below are the Base64 values above, also encoded as hex and as a string (where \0
represents String.fromCharCode(0)
).
Base64: TgBhAG0AZQA=
Hex: 4E0061006D006500
String: N\0a\0m\0e
Base64: VgBhAGwAdQBlAA==
Hex: 560061006C0075006500
String: V\0a\0l\0u\0e\0
