I've been using computers for a really fucking long time, I guess, so I have had plenty of time to use various softwares, get fed up with them, use different software, get fed up with them etc etc etc. So I'd like to share with you what I personally use and what I think works well.
I'm going to split it up into 3 sections: Linux Software, Windows Software, Old Windows Software
For the windows software I'll try to provide links but for linux naturally you would just get all that stuff from your package manager
Modern PC:
Arch Linux
Older/Strange architecture Computer:
NetBSD
Firefox
For less intense browsing:
Palemoon
O̶p̶e̶r̶a̶ ̶ ̶(̶P̶r̶e̶s̶t̶o̶ ̶e̶n̶g̶i̶n̶e̶)̶ this browser is kinda contentious because the source was illegally leaked, but this is the only way you can run it on a Unixlike OS.
uBlock Origin (ofc)
Ruffle (modern flash support)
Tree Style Tabs
Tampermonkey (user scripts)
Stylus (user styles)
Dark Reader (universal dark mode, I set it to a low contrast for my tired eyes)
TWP (web page translation)
SponserBlock for Youtube
Searx-NG (locally hosted)
wiby.me (oldweb/indie web)
Audacious
Clementine
VLC (if im terribly desperate)
XPDF
Dolphin
PCmanFM (for lightweight use, although it has a tenancy to corrupt large transfers)
Ranger (CLI, very lightweight)
XFCE4
Enlightenment16 (lightweight/Retro)
i3WM (very lightweight/laptop use)
Theming: I use GTK, and when I have to use QT I use qt5ct to theme it like my GTK theme
Icons: Chicago95
Cursor: Hand of Evil
Hexchat (IRC)
Pidgin (Everything else)
and I guess whatever dumb election app my freinds force me to use at whatever period of time
The GIMP (use to be on the photoshop train, but since I switched entirely to linux like 6 years ago Ive grown to love gimp)
ImageMagick
Converseen (ImageMagick front end for filetype conversion)
ezgif.com (this link might make you feel a bit nervous, but I assure you its a really good site with lot's of ffmpeg and imagemagick utilities for editing gifs, I use it all the time, and for a long time)
A̶u̶d̶a̶c̶i̶t̶y̶ (Use Tenacity or another fork now, Audacity was compromised)
VLC

Evolution
Thunderbird (when evolution shits the bed)
QuiteRSS
Thunderbird (not so much anymore)

Windows 10 (begrudgingly if I have to)
For less intense browsing:
Palemoon
O̶p̶e̶r̶a̶ ̶ ̶(̶P̶r̶e̶s̶t̶o̶ ̶e̶n̶g̶i̶n̶e̶)̶ Might be too too old now
