I never understood what is so problematic about anonymized telemetry, especially for a open-source product.
It provides a really valuable feedback for developers regarding feature usage, performance and error logs – you get the product for free so give something back.
I've recently switched to Firefox and I feel like it's overall a better experience – I just really miss the convenience of installing Progressive Web Applications as a standalone apps, or creating shortcuts from existing websites.
The benefit of this is that you can open them as a separate window, keeping the viewport size and hiding the URL bar.
Is there any viable alternative to this in Firefox?
