Question

I need to see running examples of extensions for Chrome and Firefox
using :

1°) IndexeDB
2°) Local storage

I d like to now if the files created by extensions in IndexeDB or “Local storage” have a filename
different from the ones created by a website.

For “Local storage” in Chrome, file name starts with “chrome-extensions”,
and for IndexedDB ?
and for Firefox ?

Thanks for help

Answer 1

Yes, extension and webpage data are always separated.

• IndexedDB in Firefox: extensions have their data in the indexedDB/chrome directory in the profile, webpages under indexedDB/http+++example.com.
• Local storage in Firefox: data is stored in the webappsstore.sqlite database, scope field determines the origin of the data. Extensions cannot use local storage.
• IndexedDB in Chrome: extensions have their data in the IndexedDB/chrome-extension_... directories in the profile, websites under IndexedDB/http_....
• Local storage in Chrome: stored in the Local Storage directory in the profile. Files containing extension data start with chrome-extension_, files containing website data with http_ or https_.
