Is this context switching normal?

Fedora version info:
[sysadmin@localhost ~]$ cat /etc/fedora-release
Fedora release 30 (Thirty)
[sysadmin@localhost ~]$
[sysadmin@localhost ~]$ uname -a
Linux localhost.localdomain 5.0.17-300.fc30.x86_64 #1 SMP Mon May 20 15:36:26 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Below is the screenshot of vmstat output from my personal laptop.
As you can see from cs column, the context switching is 2000+ . This means CPU is switching 2000 times between tasks per second. And I had 344 processes running at the time I ran vmstat. Is there something wrong with my system or is this normal ? My laptop has a 6 core (12 threads) Intel CPU.
BTW, is it normal to have 344 processes running in a personal laptop ?

Hmm. Are these tasks or threads? IMO, if they are threads its ok, otherwise if they are tasks … its too many (unless you ran a lot of programs at that time). What does htop say?

It seems to be mostly threads of Firefox.
Below is the htop output. Thanks for letting me know about this utility.
