Firefox for Android Support Forum

The issue is appeared after first time page loading and first opening of a modal. When I click on the dropdown selector (implemented through a div), the selector does not open. After clicking many times on then the dropdown - list opens. The next time after openning modal and click dropdown list - the dropdown list opens. This error is only on Android mobile in Firefox.

Actually I'm using firefox from so long and I love to use firefox and I feel safe using firefox because it is open source and firefox first priority is privacy but from few weeks I'm observing that duckduckgo app tracking blocks so many tracking attempts from firefox. It's kind of weird. When ever I open firefox, duckduckgo start blocking so many tracking attempts from firefox and as a proof I take screenshots as well. I'm attaching screenshots with this message. Still I love using firefox but also this scared me. Hope I'll get a better explanation.
