galaxy s25 ultra new tab freezing

Latest version(s) of Firefox on my Android 16 Samsung Galaxy 25 Ultra are not happy - go to open a new tab and the entire app freezes - after about 10s I get offered the option of waiting - which does nothing, the same message reappears again 10s later - or closing the app. Have been trying to find resolution as Firefox is my browser of choice but nothing so far besides reverting to an old build of around 140 and refusing to upgrade. Please can this be looked at as a priority - reading up I believe a number of Samsung users are experiencing problems with the newer versions all focussed around the tab system.
