I've fiddled with more details than I've bothered to write down. Here's a couple of the less common ones (that I'd consider "essential", to me): - Customized the response curve of trackpad scrolling. (I think no other browser has this feature? It's actually the top thing keeping me on Firefox). On my specific hardware, something like this is subjectively "snappy" and "precise" and "out of my way": mousewheel.acceleration.factor = 0 mousewheel.min_line_scroll_amount.factor = -1 mousewheel.default.delta_multiplier_{x,y,z} = 40 40 40 - Disabled all fonts with about:config's 'downloadable_fonts' toggle. (An alternative is uBlock's remote-font preference, which can be toggled on/off per-domain. That's a useful escape hatch). gfx.downloadable_fonts.enabled = false - Enable uBlock Origin's opt-in "annoyances" filters, which affects maybe half the web including every last GDPR banner: https://github.com/gorhill/uBlock/wiki/Dashboard:-Filter-lists https://github.com/gorhill/uBlock/wiki/Dashboard:-Filter-lis... - userChrome.css is much more featureful than I understand; I just use it to adjust native widget font sizes: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); #tabbrowser-tabs .tab-text { font-size: 13pt !important; } #urlbar { font-size: 17pt !important; } - Firefox bookmarks can have *keywords* that macroexpand in the URL bar; these lower the friction of casual non-Google queries: en -> https://en.wiktionary.org/wiki/%s#English man -> https://dyn.manpages.debian.org/jump?suite=bullseye&binarypkg=manpages&language=en&q=%s hn -> https://hn.algolia.com/?q=%s - Obscure privacy settings that should have gone into the main privacy panel, IMO: beacon.enabled = false network.http.referer.spoofSource = true https://developer.mozilla.org/en-US/docs/Web/API/Beacon_API https://developer.mozilla.org/en-US/docs/Web/API/Beacon_API https://wiki.mozilla.org/Security/Referrer https://wiki.mozilla.org/Security/Referrer
