Hey guys,

I am a n00b and trying to create a WebExtesion that can persist data into Firefox Profiles, but unable to find.

Is this feature not available in WebExtensions?

Do you mean, under WebExtensions we will not be able to store data into profiles?

storage.local stores data in a folder in your firefox profile. There are other methods too. Is that not what you wanted? If not, please explain in more detail what you want to do.

Thanks a bunch for answering, yeah this exactly my question, the reason I am confused is because, there is no mention on storage.local page (that you shared) that data in storage.local is stored within current profile.

I suspect most if not all types of storage are held in your profile, though storage.local is the only one I’ve used. It’s for simple key:value pairs and is stored in the ‘browser-extension-data’ directory so you can see and edit it. See also storage.sync

Then there’s IndexedDB - which is also held in your profile: [https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB\_API/Browser\_storage\_limits\_and\_eviction\_criteria](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API/Browser_storage_limits_and_eviction_criteria)
