Mozilla (Suite) was similar to Netscape Commumicator and included browser, mail, webpage editor and maybe other functions as well. I don’t recall you could install the components separately. Later they decided to release a standalone browser (Phoenix/Firebird/Firefox) and then mail client (Thunderbird). IIRC they had standalone calendar (Sunbird) and webpage editor as well. Eventually they discontinued Mozilla and the closet thing would be the community-maintained Seamonkey.

Does the pen work probably in drawing or journal software (like Krita and Xournal++)?

I heard from somewhere that you can get the whole collection down to below 120GB if you compress all variants of a game into solid archive.

I’ve been a Windows user since the 90s and only used Linux occasionally. But starting with Windows 10 this thing is becoming more and more difficult to manage. The unlimited amount of popups, changing settings randomly without asking, A/B testing on difficult computers or different accounts on the same Windows installation, some settings only appear after a while or opening/closing the software several times…

It’s so painful to deal with. I’ll probably switch completely to Linux soon when I have spare time.
