Open up the browser go to the the menu whatever go down to site settings under settings on the browser not the app and change the toolbar hide toolbar feature

Open up Firefox in the web browser go to the settings for the browser settings go to site settings and change the hidden toolbar setting

Sorry but the above answers don't help because I don't find anything called Site Settings, as shown in this screenshot

My Firefox version is 68.2.0

Hi

I think that I might be able to help with this.

When you are viewing the PWA, select the three dot menu and choose to Open in... top open the site in a full copy of Firefox for Android - complete with your favourite add-ons.

I hope this helps.

Again, sorry but this doesn't help. I don't want to open the page in Firefox. If that's what I wanted, I could just create a page shortcut, but that's not what I'm asking.

The reasons why I use PWAs is because they can't be open multiple times and because they are in full screen.

If I open everything in Firefox, and use page shortcuts, they get mixed with existing tabs, they duplicate if I tap on them twice, which may use more memory and clutters the interface, and they are no longer in fullscreen.
