Hello I'm using Firefox browser for Android and I'm noticing one thing if i open a tab on Firefox and then keep it in background and open another app ,then if i return to firefox through menu then the tab i opened gets refreshed and it's really disturbing for multitasking and this problem happens even i have 6gigs of ram in my android , other browsers are working fine but firefox is refreshing. And i have another problem If i search any currency converter on google it doesn't let me input the amount on the inbuilt Google converter . So is there any fix to it?[https://www.google.com/search?client=firefox-b-m&q=usd+to+btc&oq=usd+to+btc&aqs=heirloom-srp..0l5 Link]
