please let me know if this is something I’m doing wrong on my end or if this is a known issue and you have a solution. 

I am currently using the latest version of Firefox for Apple iPhone. When I tried to close all tabs, it does not close. I click on the trashcan and click to close all tabs, and it pauses for a very long period of time and still retains all old tabs. The only way to close tabs is to go through them manually delete them one by one. Obviously this is not acceptable. I’ve been very happy with Firefox in the past, and I would hate to Have to change browser platforms, but this is getting to the point where I need to change browsers if this is not fixed soon. please let me know if this is something I’m doing wrong on my end or if this is a known issue and you have a solution. Thank you!
