Steps to reproduce:

My app requests an Origin Private File System and checks the quota provided with navigator.storage.estimate(). My app (Kiwix JS PWA) needs to be able to store large archives of web content, up to 100GB or more.

Actual results:

Provided quota is never larger than 10GB despite having over a terabyte of free space on the system drive where Firefox is installed. 10GB is a pretty small archive for Kiwix. Even adding three 4GB content archives is not possible in Firefox.

Expected results:

I would expect a much larger quota based on a percentage of free space. In the same app, Chrome offers nearly unlimited quota on a PC, and on Android a much higher quota than Firefox for Android.

The Bugbug bot thinks this bug should belong to the 'Fenix::General' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

The Bot is wrong. This is about Firefox Desktop, although it ALSO applies to Android. But the quota issue is most serious on Desktop, as users are more likely to download and use very large archives on Desktop systems.
