Hi

You can still open a second or more gab in Firefox for Android.

You can long press a link and choose to open in a new tab, or tap the screen with a 1 in it icon at the top of the screen, then tap the + icon to open a new tab.

"long press a link and choose to open in a new tab"

As of yesterday's (8/29/20) new version of Firefox for Android, that no longer works for me. This is unacceptable. Unless it gets fixed, it's going to drive me away from Firefox for much of my browsing. There's no telling when I'll want to follow a link without losing the page I'm on.

I also lost private browsing,new tabs. Log in to fire fox and help .from the 3dot menu nuts
