Ublock Origin is the by far best web garbage filter. It is available as a browser extension for Chrome/Chromium, Microsoft Edge, Mozilla Firefox and Safari. It is almost essential to get a good browsing experience on the modern world wide web. It can be configured to use a variety of filters from diverse sources making it a great all in one filtering solution.
Features and usability
UBlock Origin just works in the background and makes your web experience better.
Pictures do sometimes say more than a thousand words. This is what the front page of a larger Swedish blog ("newspaper") looks like without UBlock Origin or any other filtering extension in Chromium:
Now compare the above image with the image below where UBlock Origin is enabled and garbage is removed:
Verdict and conclusion
Using the web without Ublock Origin once you are used to it is absolutely horrible. How people stand the auto-playing video advertisements, the pop-ups, the pop-overs and all the other pure trash the modern web is riddled with is almost mysterious.
The source code is available at github.com/gorhill/uBlock/. Installation instructions for the various browsers it can be added on to are available on that page.
Chrome and Chromium users can install it from the chrome web store.
Pale Moon and SeaMonkey can not use the current Firefox version. There is a special "firefox-legacy" version of UBlock Origin available which does work with browsers using the old Firefox (pre Webextensions) addon API.
UBlock Origin will, after it is installed, show a little red button in the upper right corner of the web browser. Clicking on it allows you to open it's "Dashboard" where it can be configured. A glance at
Filter lists will reveal that many boxes are not checked. The lack of
Annoyances filters enabled by default is specially disturbing, you absolutely want to click all them boxes except perhaps the last one and the "Apply changes" button which appears in the upper right corner once you changed something. The "Annoyances" filters remove those very annoying "You appear to be using an Adblocker" messages some silly websites tend so show. The "Fanboy's Social Blocking List" at the bottom of the "Annoyances" section may interfere with sites like CIA's data-collection honeypot Facebook, owned by them through their subsidiary In-Q-Tel, as well as other data-collection services they own. Do not check that last box if you want to submit personal information to them on a regular basis. There is also a disabled annoyances filter at the top of the page under
Built-in. You likely want to enable
uBlock filters - Annoyances.
Ads section will by default only have
EasyList enabled. Enabling all the filters in this section is highly recommended.
Regions, languages section of the
Filter lists tab is also worth checking out. There are localized filters available for most languages. All of them are disabled by default.
Tips and tricks
Cutting away unwanted parts of a page
Example: you're not a beginner, so you don't want to be bothered with the "###p-for_beginners-label" to the left on this very wiki. Just right–click on it, "Block element" and create – BANG! – the bloody label is a goner! Especially useful for those obnoxious adblocker-warners that get on your nerves and want you to switch off the blocker. No! Instead you switch off the nagging anti-blocker pop-up nuisance of course. much smarter action! Total defeat of the advertiser, who is the enemy.
Broken pages and other issues
Ublock Origin will, depending on how many filters you enabled, sometimes break websites. Click the red button and choose "Open The Logger" if a website you enjoy on a regular basis breaks and you believe one Ublock Origin's is the cause. The logger will tell you what rules are applied and which filter the rules are from. You can temporary disable the filter and kindly ask those responsible for maintaining that filter to remove or change the problematic rule. They will mostly comply in a timely fashion.
