I use uBlock Origin's element picker and element blocker features to just make the popup notices disappear, without accepting them.
But that's mostly just a habit of mine that I know is pretty useless, as websites don't need cookies to track you, and I really don't know why they even bother anymore.
Try using the extension "I don't care about cookies"
It's excellent. I have needed to disable it occasionally to make basic site functionality work on some sites that I absolutely need to use, though I'm forgetting which ones.
Don't bother with this extension as it can't delete other storage locations where there is persistant storage. Also Firefox has TCP, Total Cookie Protection so you don't need them anyway.
I'm not sure if Cookie AutoDelete hides or auto-accepts cookie popups, but that was the main motivation for using "I don't care about cookies" -- I don't want to see all these ridiculous cookie notices on every site I visit.
There's still Ricoh. I literally found a big one in the streets that worked perfectly (I suppose the small company that was at this address needed something bigger).
Generic cartridges are just find and you refill them easily.
It might sound stupid, but since I have a smartwatch and only filter the mot important notifications on it (calls, SMS), all other notifications can sit on my phone & wait for hours. Whatever. I still can be reached in an emergency.
I don't event check my phone to get the time, duh, that's a watch !
I discovered Pidgin in 2010. We could use chat system via a plug-in, and out school were using their "own" protocol for an internal chat system, AKA NetSoul.
You either had the choice of the CLI NetSoul client, a GTK one not-so-great, or a plug-in into that awesome thing that is Pidgin.
Nowadays I use it For Lync, the Business version of Skype.
I'd go starting with it and let a community build by itself around it, tho.
