Firefox for Android Community Forum

1. Open the Firefox for Android application 2. Either browse around first, download something beforehand, or do it right at the start, go to the 'three dot' menu on the top right screen and select the 'Downloads' section. 3. The application will freeze without opening the section and after a while will say 'Firefox not responding' before crashing.

Out of nowhere, the browser stopped when I was browsing and the pages started showing slowness. 👇🏻👇🏻👇🏻
