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).
Admittedly I tend to always see as a bad thing whenever I see phone models without headphone jacks, that said for the last five years I've been using phones without headphone jacks and using the wired headphones they came with is enough for the few times I need to use them.
