Local storage limit

Question

I am working on local storage. I had referred few articles on local storage and what I understood it local storage limit is varies from browser to browser. I have two query regarding this.

1. how to set local storage limit of all browser in JS?
2. IS there any way if we can increase this value for all browser?

Answer 1

localStorage max-limits currently vary per browser from:

1. 2MB (Android Browser on Mobile); to
2. 10MB (Chrome & Firefox on Mobile and Chrome, Firefox, Opera & Internet Explorer 9-11 on Desktop).

In theory, the size of localStorage can be customised if the user-agent allows it...

... but it does not appear that any of the browser vendors have opted (at this point) to enable any front-end customisation of their browser's localStorage maximum limit.
