Parrot 4.6 KDE - Firefox slowness

[whoisflynn (Alec)]

Briefly describe your issue below:
Issues with web browsing in firefox using Parrot Security 4.6 Security Edition. I haven’t done comprehensive troubleshooting on it yet, but wanted to see if other people were having this issue. When I try to use Firefox in it’s very slow. I don’t have the same experience with the 4.5 Security Edition - MATE desktop.

What version of Parrot are you running? (include version (e.g. 4.6), edition(e.g. Home//KDE/OVA, etc.), and architecture (currently we only support amd64)
Security 4.6

What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)
Standard

Configured to multiboot with other systems? (yes / no)
No

Thanks @s1udge, @RedRuby and @retardedCode for your help and advice, I did follow the Linux Foundation’s introductory Linux course. Actually, I have used Ubuntu-Mate 16.04 for about a year then I had to return to Windows because of the poor handling of images in LibreOffice. Being deeply upset by Microsoft’s increasingly invasive behavior, I have decided to give another try to Linux and found Parrot OS a very tempting distro. Besides, the community is very responsive and helpful. Thanks again to all.

It would be nice to know what kind of machine you’re running on, remember KDE plasma has a lot of flashy(useless) frilly things and is one of the most resource heavily desktop environments. You can change some of firefox’s performance settings in its preferences on the General page under “performance”. Uncheck the default option a lower number of process (default is 8).

For me Firefox and other apps is working like cheese…

I am thinking your hardware is not strong enough.
