Thanks Walter, using your advice I was able to write this Violentmonkey script:
The last problem is that I cannot open the Violentmonkey menu in Firefox due to a display bug. But I could in Chromium where I can confirm it works.
edit: I was able to open the Violentmonkey menu in Firefox by temporarily setting browser.uidensity to 2 in about:config
In my Firefox the Violentmonkey configuration page is at moz-extension://8a1dd640-1fac-45b0-8b40-04e9cb5bd670/options/index.html this url may or may not work for you.
Code:
// ==UserScript==
// @name Make forum.pine64.org usable on PinePhone
// @namespace Violentmonkey Scripts
// @match https://forum.pine64.org/*
// @match http://forum.pine64.org/*
// @grant GM_addStyle
// @version 1.0
// @author -
// @description 3/27/2022, 4:51:54 PM
// ==/UserScript==
console.log("executing userscript on forum.pine64.org")
GM_addStyle('#container { min-width: 100px; }');
