Block private browsing mode detection #11543
Description
A number of websites use the navigator.storage.estimate() API to detect users in private browsing mode. That API returns a hard-limited quota of 120MB in private browsing, and larger values otherwise.
This has been proposed in Chromium, but appears to be a wontfix as the quota is intended to be kept fully in-memory for private browsing sessions.
There are several options here, including increasing the available quota as a temporary workaround, or simply lying about the available space (it is an estimate, after all!).
Edit: for future reference, the QA pass for Android below was completed using the following HTML:
<html>
<body>
<script>
navigator.storage.estimate().then(estimate => alert(estimate.quota))
</script>
</body>
</html>
