Firefox things to make Discord "better"

README

These are my personal things for making Discord's web app bearable for me -- a barebones text chat application.
Almost all nitro / payment / game / voice chat stuff has been hidden / blocked. 
If something breaks / looks wrong, I'll probably eventually fix it myself, but please leave comments.
A lot of the ublock filters only work if your language is set to English.

Strongly recommend 

08/22/2022 - as of current PTB, performance on Firefox has yet again worsened.
Related bugzilla entries:
https://bugzilla.mozilla.org/show_bug.cgi?id=1605271
https://bugzilla.mozilla.org/show_bug.cgi?id=1763433

07/07/2022 - blocking /profile also prevents your own profile change window from popping up somehow. Thanks Discord~.
Also add URL blocklist option blocking (as of current day it's 250kb), but commented out.
and MORE nitro payment stuff
and "about me" blocking again
and more bot garbage (another bot tag, this is like the 5th one changed in 2 years, and the "add to server" button)

06/05/2022 - stylesheet updated to fix spoiler text as well as a few color changes.

05/12/2022 - new endpoints (PTB?) for "home" channel (feed, active channels), forgotten stickers and events endpoints

04/28/2022 - add compact mode bot tag

04/27/2022 - block chat "start activity" button pushed to PTB, add experimental emoji preview / emoji button blocking

04/26/2022 - block typing indicator, on PTB it causes the whole chat window to shift up by a few pixels any time it shows up

04/20/2022 - actually block the nitro boost button in chat box

04/19/2022 - nitro boost button in chat box, new member leaf, other misc stuff

06/01/2021 - stages.

05/14/2021 - no longer maintaining the stylesheet, discord changes too much too fast and I don't even have the motivation to
bother fixing the chat colours when they're probably going to be changing it every 2 weeks until the inevitable acquisition.
Sorry.

05/05/2020:
thanks for ruining everything and changing your domain for no reason. ♥ love ya discord

Does this make Discord faster with Firefox?

Not at all. Discord intentionally makes performance ass on Firefox. Disabling the markdown preview while you type feature does improve a bit, but who knows how long they'll keep that as an OPTION.

If anyone cares enough to change the colours back to what they were, be my guest. Discord's a shitty company and constantly changing every few months for no reason.
