Unable to increase local storage for an application (game)

[Crunchiex]

My game save failed and a warning popped up that I should increase the size of the LSO. 

However, all I have on the pop-up window are the "allow" and "deny" options.

Also, when I go to Windows Control Panel, same thing.

I'm mainly using Flash in Firefox, the precise version is Firefox Quantum 64.0 (64-bit) and it says it's up-to-date.

My Windows Version is Windows 10 Home Version 1803 OS Build 17134.471

I'd really appreciate any help since I'd love to be able to finish my game!

It's a bug in Firefox.

1514889 - Flash Player cannot write Local Shared Objects on Windows (x64 sandbox)

The easiest workaround is to use another browser.

Thanks for your answer. It's getting increasingly hard to find a browser that allows Flash content. I've already switched from Chrome to Firefox for support of Flash. Now that's broken again as well.   For a long while I used the LTS version of Firefox and that didn't give me much problems. I'll have to look into how many stored passwords, cookies etc. I need to backup/save/make a note of/ before I switch again.

If you haven't, try the latest Firefox ESR.  This change has been in the Firefox Nightly for a while (since May), but my sense is that it just landed in Firefox 64, because I just started seeing reports of it.  You should be able to install the generally available and ESR versions in parallel.
