Wondering if we were allowed to keep socks during prayers?
Also during those sad times, do you know if it exists some websites where sheikh lead the jumuaa prayers online ? And if yes is it allowed to follow jumuaa online from home ?

There is no problem in keeping socks on in salah (not allowed in Wudhu though)
Salah cannot be performed online under Shi’a fiqh whatsoever. This applies to congregational prayer too.
