Opacity/transparency for firefox

valkm1 · December 29, 2023, 11:56pm

Hi,

Help needed to identify solution and steps to achieve it

Problem:
I want my firefox to be transparent so I can see another firefox (2nd window) non-transparent in background. Alternative if 2nd window is another chrome browser it is also ok.

I installed picom but do not know if its correct application to provide desire intention. Found a tutorial - https://www.youtube.com/watch?v=Xa_s_J2Jsnk

Concluding statement:
Please let me know best approach and steps to do it. I do not want to mess my arch setup, I recently have to uninstall librewolf to avoid screen freezing.

I tried to put this example for alacritty and migrated to toml file. Any idea on what to configure for firefox

github.com

tmcdonell/config-alacritty/blob/master/alacritty.yml

# Configuration for Alacritty, the GPU enhanced terminal emulator

# Any items in the `env` entry below will be added as
# environment variables. Some entries may override variables
# set by alacritty it self.
# env:
  # TERM env customization.
  #
  # If this property is not set, alacritty will set it to xterm-256color.
  #
  # Note that some xterm terminfo databases don't declare support for italics.
  # You can verify this by checking for the presence of `smso` and `sitm` in
  # `infocmp xterm-256color`.
  # TERM: xterm-256color-italic

window:
  # Window dimensions (changes require restart)
  #
  # Specified in number of columns/lines, not pixels. If both are zero this
  # setting is ignored.

I don’t know how to solve your issue but I’m pretty sure this would not be the way to do it

valkm1 · December 30, 2023, 12:47am

I found this reddit post
Can someone tell how can I implement on endeavouros

If you are using KDE Plasma, try the following:

Go to System Settings > Window Management > Window Behavior > Titlebar Actions.
In the Mouse wheel dropdown, select Change opacity.
Click Apply.

Now when you scroll your mouse wheel while hovering over a window’s titlebar, such as your topmost Firefox window’s titlebar, the opacity of that window will change.

Amazing! It works on windows setting or terminal.

Not on the firefox. Any idea to resolve?
I just wanted the background to transparent not the text inside. Any config to fix this?

kwg · December 30, 2023, 1:15am

It works for me with Firefox.

Unfortunately, this technique changes the opacity of the entire window, including text, menus and window decorations.

valkm1 · December 30, 2023, 1:41am

It works now
I had to enable the toolbar for firefox
