Thunderbird on the desktop; K-9 Mail on Android.

Couldn’t agree more, two years ago I was gifted a small wireless speaker which works fine and everything but I sometimes even forget to charge it because its cable is a 15cm short USB-A to Micro-USB one which somehow is the only Micro-USB cable I have left at home as I didn’t have any other device with that port in years and I had thrown away a few cables when I last moved. Now whenever I am looking for a new electronic device USB-C is one of the first things I check and it’s a deal breaker for me.

I use the following ones (on Firefox), except for uBO the others are just for conveniency:

• Bitwarden
• Gesturefy (for some time from early 2021 to late 2022 I used to use Vivaldi as my primary browser and now if I’m using a mouse, not having gestures in a browser feels odd…)
• LibRedirect
• Plasma Integration
• uBlock Origin (middle mode and with some additional lists)
• User-Agent Switcher and Manager (if I find a site that says it doesn’t work with Firefox).
