Ratings and reviews

When I open the app, I'm brought to the top of my tabs instead of the most recent tab at the bottom or where I left off, so I need to scroll or open a new tab to get back down. Because I have to scroll to the bottom, I keep accidentally closing tabs and undoing the action despite scrolling straight down. Also, the app keeps crashing now. It usually happens around 5x in a row despite me closing and reopening the app, which gets frustrating.

One of the best mobile browsers I've ever used due to the ability to freely add extensions. However, with the latest update, the search query shows up in the url bar instead of the actual url, which looks strange and doesn't let me easily know if the url I'm at is correct until the page loads/I restart the app/I copy and paste with Share, and renders copying/editing DDG !bang site links difficult. I've never seen another browser do this and it irks me. Maybe add a tab swipe-to-close toggle too.

Works very well for most things, and having sync with my desktop for passwords etc is super useful. However it still struggles with multiple tabs; very often the "open in a new tab" will open a black page that I cannot scroll or refresh, and if I open enough of them at a time, the page I'm opening links from eventually stops working as well (no new content loaded when scrolling). The only solution is to close the tabs and reopen them immediately.
