I think pacman support somethings similar. In /etc/pacman.conf you can add packages to a ignore list. I only used it when nvidia driver gives me problems which it has been a few years at this point.

# Pacman won't upgrade packages listed in IgnorePkg and members of IgnoreGroup
#IgnorePkg   =
#IgnoreGroup =

I kinda need ffmpeg to be up to date and want ffmpeg-full to be accessible. Not sure how this feature solves my needs.

Avoid Gecko-based browsers like Firefox as they’re currently much more vulnerable to exploitation and inherently add a huge amount of attack surface. Gecko doesn’t have a WebView implementation (GeckoView is not a WebView implementation), so it has to be used alongside the Chromium-based WebView rather than instead of Chromium, which means having the remote attack surface of two separate browser engines instead of only one. Firefox / Gecko also bypass or cripple a fair bit of the upstream and GrapheneOS hardening work for apps. Worst of all, Firefox does not have internal sandboxing on Android. This is despite the fact that Chromium semantic sandbox layer on Android is implemented via the OS isolatedProcess feature, which is a very easy to use boolean property for app service processes to provide strong isolation with only the ability to communicate with the app running them via the standard service API. Even in the desktop version, Firefox’s sandbox is still substantially weaker (especially on Linux) and lacks full support for isolating sites from each other rather than only containing content as a whole. The sandbox has been gradually improving on the desktop but it isn’t happening for their Android browser yet.

I still use ironfox because of uBlock and dark reader. Cromite is also good.

ImageMagick does support displaying images but it only supported when you use x11 (Xwayland).

# the `display` command will give you a missing error even if you have ImageMagick installed (At least on my winget installation of ImageMagick)
display image.png
# give you a x11 error on windows
magick display image.png

if for some reason you want something similar you could use ffplay it both supported on windows and x11 from what I know.

I tried it for batch conversion and I was very disappointed it somehow skipped files on big batches

I haven’t had any issues with ImageMagick with converting images, but I would rather use a dedicate command for encoder like avifenc, cjxl, cjpegli, and cwbep, since they have more options than ImageMagick or utilize newer encoders, such as cjpegli.
