How to hide “What’s happening” trending topics on Twitter.com (and more, working June 2023)

Updated 6 June 2023

Twitter can be a great source of connections, industry news and light-hearted fun (if you follow the right people!). Unfortunately, the “What’s happening” trending topics sidebar can be a constant source of misery that by now can be simply too much to bear.

If you’d rather keep on top of your news and trends in a more mindful way rather than have it shoved in your face every time you browse your feed on a desktop browser then here’s what you can do.

uBlock Origin

uBlock Origin (ChromeFirefoxEdge) is a fantastic ad blocking tool which blocks a huge array of banner advertisements, analytics, tracking and even Twitter promoted posts and YouTube video ads.

No – this post isn’t sponsored or affiliated – it’s really just that great. Browsing the web without can really be a miserable experience.

As a bonus, it also comes with a nifty feature that allows you to set your own blocking rules.

Once installed, click the uBlock Origin button in your browser toolbar and select the ‘Dashboard’ icon (looks like three cogs). On the dashboard page, select ‘My Filters’ from the top bar.

The ‘My Filters’ page will show a large text box. You may find it empty or populated with custom rules you have already created. We’re able to add to this list to block any elements we please. Simply paste in your desired filters from the filter rules section below and select ‘Apply Changes’ when done.

Filter Rules

Twitter’s dynamically generated HTML & CSS classes can make targeting specific elements a little fiddly. Fortunately, there are a number of accessibility labels and other fingerprints we can target to purge the website of unwanted features.

23 Best Free Website Testing Tools 2022

Jump to Section

Without the expertise (or perhaps simply the time) to analyse the code and efficiency of your website it can be difficult to tell how well the website is performing technically. Fortunately, there are a number of tools and online testing services that can reveal many different things about your website.

I believe that these tools are useful to promote discussions and new ideas about optimising a website, covering the basic optimisations or help to identify larger underlying issues ? but sometimes their recommendations can be at-odds with what is best for the end user. For example, Google PageSpeed will not offer a top score if you embed Google Analytics, Google Web Fonts. Conversely, it can offer perfect scores for websites that are truly horrible for real users. I would rarely recommend aiming for a perfect score on many of these tests, just a happy balance between a great, fast-loading and useful website for humans and an efficient & semantic source code.

Tools listed in this post are either free or have a sufficiently powerful free tier. I am not affiliated with any of them.

That aside… here are my go-to’s!
