Thought about doing this a while back, but I only got round to it now. Here's a list of browser extensions (and another list of a few bookmarklets) I use that I think other people might like!

Whole extensions

Note: I use Firefox, so they definitely all work in that (and the links are for Firefox), but most of them should be available for Chrome as well.


Tweak New Twitter

Adds a shitload of extra customisation options to Twitter (but you gotta access them through the browser extension settings). Big features I have on (almost) all the time:

  • forces Twitter to Latest/chronological timeline
  • hides unwanted sidebar features (e.g. Trending)
  • un-inverts Follow/Following buttons (so Follow is empty and Following is filled)
  • hides Verified notifications tab
  • replaces Twitter Blue checkmarks with the Twitter Blue logo so you can tell who paid 8bux at a glance
  • hides selected menu items
  • bypasses the verify dialog for blocking someone (a little extra convenience)

And some other features I think people might get a lot out of:

  • can hide all posts by verified accounts
  • can move retweets and quote-tweets to a different timeline
  • can switch off the Chirp font I know a lotta people were having issues with
  • can hide the quoted tweet when looking at quote-tweets all quoting the same tweet
  • can hide tweets quoting accounts you've muted/blocked
Link Gopher

This does something super-simple, that I almost never need, but makes things go a lot faster when I do need it: it gets all (or a filtered set) of the links on your current page and lists them out for you.

Torrent Control

Use this for [homer]legitimate[/homer] purposes only.

Wayback Machine

The Internet Archive's browser extension. Lets you archive pages or see archived versions without having to go through the main site.

Security and blockers

uBlock Origin

Accept no substitute. It's just a good adblocker.

HTTPS Everywhere

I think this comes with Firefox by default now? Anyway it forces all pages to use https:// instead of the unsecured http://, and throws up a warning you can click through if the site isn't set up for https://.


I use Bitwarden for my passwords; this is just the browser extension that lets me access those passwords quicker.

Twitch Adblock

Does what it says it does, but also occasionally blocks the whole stream, forcing me to switch it off and on again. The UI recently started using Pepe images; there's a (very recent and so far unchecked) fork that strips those out.

Privacy Badger

Another blocker, this one from the EFF. I think they had to cut one of the key features of the extension for privacy reasons, though (something to do with it learning new ads/trackers/etc. to block and building a personalised profile AFAIK?).

Image tools

Webp/Avif image converter

Lets you save these files as more common image filetypes (e.g. save .webp as .png).

Right-Click Borescope

Helps download images that you can't right-click—doesn't always work, though.

Video tools

Youtube Video and Audio Downloader

This does what it says, but I had a lotta trouble using the audio converter, so if I wanna get audio I open the “Download Panel” and go to the end, where the audio-only video downloads are, download the audio-only .mp4 if it's there, and convert it using FFmpeg via Audacity.

Use this for [homer]legitimate[/homer] purposes only.


A crowd-sourced app that lets people mark sections of youtube videos as sponsorships (or a bunch of other things, see below), and lets each user choose what their browser should do, e.g. mark the video timeline in a different colour, warn you, or even skip them automatically (and you can control what it does for each type of thing it can mark). It's not just sponsorship segments, though, it also includes:

I just use it to skip sponsor promo segments, though.

Age Restriction Bypass for Youtube

Fuck off, Google, I'm not sending over legal ID just so I can watch videos that were inappropriately tagged as adult-only.

Return Youtube Dislike

Useful for if you wanna make Futurama neutral videos stay neutral.


If you don't know, bookmarklets are little bits of javascript that sit in your browser's menu and that you can run at the click of a button to do (usually simple) tasks. I don't use these super-often, but they're handy to have:

lets you hover over text to see what font it's in or click on text to see more details, like the font stack
(minus sticky) removes all display: sticky elements on the page; handy for getting rid of chunky menu bars, chat widgets, etc.
Reading Order
highlights elements with display: flex or display: grid and adds a number showing their order if you were tabbing through or reading through with TTS (most useful for devs, probably). Made as proof-of-concept for a feature that might now be implemented in common browsers by default, I dunno
