On my iPhone I have one called Save All Images. Basically you know how lots of sites especially any kind of social media where they want you there to see things… anyway they use a script or whatnot to prevent holding down on an image to get the save photo prompt. This is an extension that loads all images that are single level referenced and you can save any/all. I use it almost daily. Instagram, and the like, especially, they hate the notion of someone saving something.

In Firefox on my computer I have Element Blocker. Some websites just waste a lot of screen space so if you’re browsing a ton of content you’d like to get the most room, but some stuff takes up portions of the screen fixed and not movable. This extension lets you select an element and it makes it just disappear. It is absolutely essential.

I use uBlock Origin, Malwarebytes, Privacy Badger, Bitdefender's Trafficlight and Simple Translate.

The last one is useful for translating selected text.

Wikiwand, a much better UI for Wikipedia

I try to use a minimum for performance reasons. My big three are uBlock Origin, Dark Reader and a password manager.

Foxy Gestures. I love having mouse gestures for Close Tabs on Right, Back, and Close Tab, amongst other.

Zoom Page WE, automatically zoom to full width. Really useful for "convergence" pages, ie: lazy web developers that think every browser wants a 4 word wide column. You have to set "Automatically Zoom" in preferences, it doesn't work out of the box.

if you're going for ultimate privacy... none, ironically.

surfingkeys - extension which add vim keybindings for control your browser without mouse

Imagus feels like in an alternate universe it could be default browser behavior. When you hover over an image it will expand to full resolution and then you can press buttons to open in new tab, download, zoom in, etc.
Works on pretty much any website and is nice if the website has sized the images too small or if your eyesight is less than great.

• Freetube Redirect
• Imagus Mod: Enlarge and display images/videos from links with mouse-over. Reddit-hole.

Kill Sticky is a really good one, makes even the most bloated websites readable.

Ublock Origin, dark reader, bitwarden and user agent switcher if websites are throwing a fit about firefox.

Don't know if the other browsers have it, but I use Marker by robin-rpr on Firefox desktop. Simple Enough extension for being able to draw/annotate/highlight on browser screen. Was doing some college work in class and wanted to be able to quickly write out and convert binary. Helped so much to be able to do it in browser so I could easily see the numbers.

Though, it was last updated October 22, 2022, so keep that in mind if you're like me and don't always like using software that's more than a few years old (games not included). The alternative I saw (Web Marker by SFer) is under an "All Rights Reserved" license, but was updated last month (June 8th), so pick your poison.

I'm surprised I haven't seen any recommendations for "Indie Wiki Redirect" as Fandom (the wiki site, common for games) has started shoving ads down users throats, so wiki maintainers are moving to other sites like wiki.gg, but search engines still show Fandom as the first result.

Wayback Machine and also archive.is's addons. I archive webpages frequently so they're super helpful. And if a webpage has been taken down you can easily go to an archived version with the Wayback addon.

Also, Vimium C. Not for everyone and definitely down to personal preference rather than "I recommend this to everyone", but I'd struggle to browse the web comfortably without it.
