What are the size limits of the backends on browser?

[Davilarek]

Hi there, My project requires storing lots of data, around 100 megabytes. I would like to use zen-fs on browser environment. It's important to note that the data needs to persist between reloads and even restarts of the browser, essentially, making the data kind of permanent. Hence my question, what are the size limits of the available backends in a browser?
