I would add password manager to that list.

Try out Librewolf it’s Firefox fork which is hardened out of the box so you don’t have to mess with settings too much.

Router like this are very low spec for example Fritz!Box 3270 has 360 MHz 1 core CPU, 64 Mb of RAM and 16 Mb of Flash. Only thing you can do with them is flashing OpenWrt, but its latest version doesn’t support devices with or less than 8 Mb of flash and 64 Mb of RAM.

I will add that this are permissions requested by the app and this doesn’t mean that system granted access to them.
