uBlock-for-firefox-legacy VS palefill

Extensions explicitly designed for the old extension system still work.

https://github.com/gorhill/uBlock-for-firefox-legacy

Also works with Pale Moon. There are even special builds of Pale Moon that will run on Windows XP.

Mozilla SeaMonkey still has the HTML editor (and has been updated within a year!)

If you want to test it out, make sure you install https://github.com/gorhill/uBlock-for-firefox-legacy/release... from there, because it won't show up in the extensions search.

Of course you can: XPI file

I recommend Pale Moon http://www.palemoon.org/ (definitely doesn't steal your data, or tracks you at all. It also doesn't do bloat or junk. In fact it even uses less resources than chromium or firefox) with adblocker (advanced) https://addons.palemoon.org/addon/ematrix/ and/or (average) https://github.com/gorhill/uBlock-for-firefox-legacy/releases

Firefox 59 & Mypal 29 work with Ublock Origin Legacy <-use this link if GitHub's broken

Mypal 29: click this link: https://github.com/gorhill/uBlock-for-firefox-legacy/releases/download/firefox-legacy-1.16.4.30/uBlock0_1.16.4.30.firefox-legacy.xpi & follow the prompts.

i'm using pale moon and this legacy fork of ublock origin, which quite possibly is the issue.

for adblocker there is https://github.com/gorhill/uBlock-for-firefox-legacy/releases , for windows xp x64 there is https://archive.org/details/WindowsXP_Professional_x64_SP2

Pale Moon supports XUL add-ons, but there is uBlock Origin among others. Which are you lacking?

It cannot render modern sites without a polyfill addon to improve compatibility because they are worried more about legacy extensions and an old UI than providing a usable browser https://martok.github.io/palefill/

https://martok.github.io/palefill/ or the direct link https://github.com/martok/palefill/releases/download/v1.26/palefill-1.26.xpi

Until the soon-to-be V32, you need https://martok.github.io/palefill/ to use github sites. Since they switched to only work on google chromium standards.

Almost-must-have addons I'd recommend out of the gate is https://martok.github.io/palefill/, for chromium polymer sites, like GitHub. https://github.com/gorhill/uBlock-for-firefox-legacy/releases, which is self-explanatory, and https://addons.palemoon.org/addon/ematrix/, which works well together with uBO and shows what's what re third party injections and can block them.

PaleFill for GitHub's chromium-only site: https://martok.github.io/palefill/

You'll need PaleFill (https://martok.github.io/palefill/) before you can install uBlock Origin though.

If you use Pale Moon and struggle with some modern websites, you can enable more HTML5 features by installing the Palefill add-on as well as setting these properties to true in about:config: dom.animations-api.compositing.enabled dom.animations-api.getAnimations.enabled dom.animations-api.implicit-keyframes.enabled dom.animations-api.timelines.enabled dom.dialog_element.enabled dom.getRootNode.enabled dom.imagecapture.enabled dom.push.enabled dom.serviceWorkers.enabled dom.storageManager.enabled dom.webcomponents.enabled media.av1.enabled media.getusermedia.audiocapture.enabled media.mediasource.webm.enabled media.track.enabled media.webspeech.synth.enabled media.webvtt.regions.enabled Keep in mind that some of them are experimental (like ImageCapture) and may be unstable.

Do you know that you can improve HTML5 support in Pale Moon by setting these properties to true in about:config? dom.animations-api.compositing.enabled dom.animations-api.getAnimations.enabled dom.animations-api.implicit-keyframes.enabled dom.animations-api.timelines.enabled dom.dialog_element.enabled dom.getRootNode.enabled dom.imagecapture.enabled dom.push.enabled dom.serviceWorkers.enabled dom.storageManager.enabled dom.webcomponents.enabled media.av1.enabled media.getusermedia.audiocapture.enabled media.mediasource.webm.enabled media.track.enabled media.webspeech.synth.enabled media.webvtt.regions.enabled Check the HTML5 Test before and after. Also install Palefill.
