Open “More Tools” -> “Task Manager” in Chrome.
Open the twitter web app and find the tab in Task Manager. Mine started at 120MB.
Start scrolling and see how long it takes to crack 500MB.
I know it’s not directly related to data stored in Redux considering most of it is gifs, etc, but it is related I think it demonstrates that talking about limits of 100KB is not worth the thought involved. I’d be very surprised if you could find a device with a browser that had any issues with even 10MB.
