Use Firefox & Tree Style Tab with `userChrome.css`

This code will hide Firefox's horizontal tab strip in favour of solely using Tree Style Tab's vertical tabs. It will leave space for window buttons on the top left in a space of the same colour as the toolbar. This code is also optimised for full screen and both dark and light mode. Since the code is .css only, it does not require setting up autoconfig.js.

Tested on: macOS 11 (Big Sur), macOS 12 (Monterey), macOS 13 (Ventura), Windows 11, and Arch Linux (running i3wm).

Adjusting the Grub Bootloader for a HiDPI Screen

The text size on Grub, when running on a computer with a HiDPI screen (e.g., 2880x1800 at 13 inch), will often appear too small. Lowering Grub's resolution is one solution. However, it will make Grub's interface pixelated. A better way is to enlarge the font size itself and not mess with the resolution.

We can start by deciding what font we want to use for Grub's interface. I recommend using a typeface that is specifically built for the absence of anti-aliasing, such as Unifont.

Changing the font size of Grub means replacing the binary .pf2 font file that is compatible with Grub (regular .ttf files can't be read by Grub). This is because the font size is hardcoded to the binary. To create that .pf2 file out of the Unifont typeface, we can run the following in the command line:

sudo grub-mkfont --no-hinting -s 32 -o /boot/grub/fonts/unifont.pf2 /usr/share/fonts/Unifont/Unifont.ttf

Install Neovim Plugins after Importing Dotfiles

Oftentimes, after importing your .dotfiles (including your Neovim configuration files) to a new machine, installing your Neovim plugins using :PlugInstall (if you're on vim-plug) isn't ideal. This is mainly because of all the error messages that you would have to skip through before you're even able to run the install command.

This can be circumvented by doing the following:

nvim -u .dotfiles/.config/nvim/plugins.vim --headless +"PlugInstall" +"qall"

Switching Display Manager in Arch Linux

You might have more than one display manager installed in your machine. To switch from lightdm (the default DM in EndeavourOS) to, say, sddm because you want to swap i3wm with swaywm, you can use the following commands:

First of all, determine the name of your display manager running the following:

systemctl status display-manager

It will return something like this:

Change the Default Terminal in `i3wm`

To change the default terminal, you can modify the order in the /usr/bin/i3-sensible-terminal file:

- for terminal in "$TERMINAL" x-terminal-emulator mate-terminal gnome-terminal terminator xfce4-terminal urxvt rxvt termit Eterm aterm uxterm xterm roxterm termite lxterminal terminology st qterminal lilyterm tilix terminix konsole kitty guake tilda alacritty hyper wezterm; do
+ for terminal in "$TERMINAL" kitty alacritty x-terminal-emulator mate-terminal gnome-terminal terminator xfce4-terminal urxvt rxvt termit Eterm aterm uxterm xterm roxterm termite lxterminal terminology st qterminal lilyterm tilix terminix konsole kitty guake tilda alacritty hyper wezterm; do

    if command -v "$terminal" > /dev/null 2>&1; then
 exec "$terminal" "$@"

Change the Default Terminal when Opening `htop` Through `dmenu`

Change the following lines in htop.desktop (find this file through locate htop.desktop):

- Exec=htop
+ Exec=kitty -e htop
- Terminal=true

Change the Default File Manager to Krusader

Run the following in the command line:

xdg-mime default org.kde.krusader.desktop inode/directory

Getting Non-Latin Input Methods to Work on Arch-based Systems

To input non-Latin languages such as Mandarin Chinese and Japanese, one would need to install an Input Method Framework (IMF) and an Input Method Editors (IME). For me, the IMF that works best is Fcitx5, which is designed to be lightweight. In Arch-based systems, installing it is straightforward:

sudo pacman -S fcitx5

To use a GUI for configuring Fcitx5, install fcitx5-qt:

sudo pacman -S fcitx5-qt

	# Allow the use of functions in prompt
	setopt PROMPT_SUBST

	# Colours
	autoload -U colors && colors

	# Exit code
	local exit_code="%(?,,\$?: %{$fg[red]%}%?%{$reset_color%})"

	# Version control system

	/* Change color scheme to match EndeavourOS */
	/* Make sure to set the theme as `Photon` in the settings */
	@media (prefers-color-scheme: dark) {
	:root {
	--tab-border: #2f343f;
	--tabbar-bg: #2f343f;
	--tab-surface-regular: #565965;
	--tab-surface-hover: #496c9a;
	--tab-surface-active: #5294e2;
	--tab-surface-active-hover: #75a9e8;
