Usability
Kill Sticky: Kill off the annoying floating things blocking the website you're trying to see.
Tranquility Reader: Like native "reader view" but compatible with other addons and more options.
Scroll Zoom: Zoom web pages with the left or right mouse button and the scroll wheel.
Image / Video
Image Max URL: Finds larger/original versions of images (supporting 8800+ websites), including a powerful image popup feature
Invert Image: The add-on inverts color of an image or color of any part of a page. Changes white color to black, for comfortable night time reading.
Save webP as PNG or JPEG: Convert any image (WebP, AVIF, etc.) to PNG or JPEG (with choice of quality) for downloading.
TinEye Reverse Image Search: Click on any image on the web to search for it on TinEye.
Video Speed Controller: Speed up, slow down, advance and rewind any HTML5 video with quick shortcuts.
Enhancer for YouTube™: Take control of YouTube and boost your user experience!
Tools
EPUBReader: Read ePub files right in Firefox. No additional software needed!
WebStickies: (Persistent) Sticky notes for the Internet
RSS
RSSHub Radar: RSSHub Radar is a spin-off of RSSHub that helps you quickly discover and subscribe to RSS and RSSHub for your current site.
RSSPreview: Preview RSS feeds in-browser
Customization
Stylus: Redesign your favorite websites with Stylus, an actively developed and community driven userstyles manager.
Tampermonkey: Tampermonkey is the world's most popular userscript manager.
Advanced
Request Control: An extension for controlling requests. See also Redirector, not as powerful, but much more user friendly.
Modify Header Value (HTTP Headers): Add, modify or remove a header for any request on desired domains. I use this one to force sites to load only the image when opening images in new tabs.
Cookie AutoDelete: Control your cookies! This WebExtension is inspired by Self Destructing Cookies. When a tab closes, any cookies not being used are automatically deleted. Keep the ones you trust (forever/until restart) while deleting the rest. Containers Supported
uBlock Origin: Finally, an efficient wide-spectrum content blocker. Easy on CPU and memory.
uMatrix: EDIT-WARNING: as pointed by @sovietknuckles@hexbear.net, uMatrix it's not longer maintained since 2021 Point & click to forbid/allow any class of requests made by your browser. Use it to block scripts, iframes, ads, facebook, etc.
- Use ViolentMonkey it's open source and actively developed for Firefox, while TamperMonkey is originally developed for chrome
  
  Thanks for the advice!
  Sadly, I knew about that too late and I'm a heavy user of Tampermonkey. It would be painful to migrate now :(.
- Thanks for adding the links, you the mvp
- What's the difference between uBlock origin and uMatrix?
  
  I cannot answer that properly, I don't really understand them enough. I will add some copy-pasted answer on bottom. But, from a user perspective my experience is:
  uBlock origin: blocks a lot of (but not all) unwanted stuff without breaking (almost) anything. When some page does not work, tt's very uncommon that uBlock origin is the cause.
  uMatrix: blocks (almost) all unwanted stuff, but it breaks many pages by default. If a page does not work, the first thing I look at is uMatrix.
  NoScript (and similar): It's been some time since I used it (so those who are more familiar, please correct me if I'm wrong). What I remember is that it was even more strict than uMatrix. Something like uMatrix allows by default everything from the same domain as the URL but NoScript does not.
  So I would recommend uBlock origin always and uMatrix only if you are ok with some micro-management page-by-page.
  Here it's a copy-paste of the answer from the first link in the google search ublock umatrix differences:
  Chris's Wiki :: blog/web/UBlockOriginAndUMatrix
  While it's true that uMatrix and uBlock Origin have overlapping functionality (and are written by the same person), they have different purposes and focuses. uBlock Origin's focus is blocking ads and other undesired things as an out of the box experience with little configuration needed. uMatrix's focus is on exerting tight and highly specific control over what resources a page is allowed to load and use, including Javascript and cookies (and requires a lot of configuration).
  
  People still use uMatrix? gorhill archived the uMatrix repo/stopped maintaining it in 2021.
  
  Oh, I had forgotten, I'm going to add a warning to my comment thanks for noticing!
  When I was aware of that, I expected it to break at some point. But I didn't find a proper replacement... and it still seems to be working fine.
- Thank you for this list! I found several add-ons I never knew I was missing
- Thanks! These seem useful. I've only used a couple add-ons from your list. Time to try them out now.
  Your are awesome for adding links too!
- Thanks!
  Links for convenience:
  Bazzacuda Image Saver 2 Plus
  Save All Tab URLs
  Open Multiple URLs
  I will definitivaly use the last 2 ones. I don't usually need to mass download images, but it's good to know the Bazzacuda one exists!
  
  One question... do you know if it works with videos?
  I don't see anything on the addon page, but it seems weird because the use case is very similar.
  
  I think I don't undestand it properly.
  What I meant is: if I have some tabs with one video URL in each of them, it seems trivial to just automate a "click download" for each one of them.
  I mean plain MP4 normal URLs with no tricks, like imgur MP4 URLS:
  https://i.imgur.com/fsX4bq6.mp4
  https://i.imgur.com/nAu2ifG.mp4
  
  I think there is some misunderstanding... there are a lot of ways of downloading a list of URLs. For videos I use yt-dlp.
  I didn't know about IDM/IDX, I asume they are Internet Download Manager and Xtreme Download Manager, right? From what I see those are independent programs and not Firefox add-ons (correct me if I'm wrong).
  What I find weird is that, what Bazzacuda can achieve if I have multiple tabs with i.imgur.com/.../...jpg URLs does not work if I change the jpg extensions with mp4. But I'm probably missing something (or not explaining myself properly).
  Thanks!
  
  Got it, thanks for the patience :)
  It makes the job easier than reverse searching image with Yandex (which is the best method I use).
  Regarding reverse image search, this is the bookmarklet I use to lauch 5 different searches at once. On firefox you can set a keyword so I just type rev on the navbar on a tab with an image.
  If the page has more than 1 images, it tries to print a number on each one so you can specify which one you want to search... but that feature doesn't work very well. Removing that, the script would be much more simpler.
  
   
  One-liner:
  
  javascript:(function() {var url;var args = '%s';var imgs = document.getElementsByTagName("img");var imgIdx = undefined;if (imgs.length == 0) return;if (imgs.length > 1) {if (args.length > 1) imgIdx = parseInt(args[1]);if (imgIdx === undefined || isNaN(imgIdx) || imgIdx < 1 || imgIdx > imgs.length) {numberImgs();imgIdx = parseInt(prompt(`There are ${imgs.length} images, select index:`, 1));}if (isNaN(imgIdx) || imgIdx < 1 || imgIdx > imgs.length) return;url = imgs[imgIdx - 1].src;} else {url = imgs[0].src;}if (!url) return;url = encodeURIComponent(url);window.open("https://saucenao.com/search.php?url=" + url);window.open("https://lens.google.com/uploadbyurl?url=" + url);window.open("https://www.bing.com/images/searchbyimage?cbir=sbi&imgurl=" + url);window.open("https://www.tineye.com/search?url=" + url);window.open("https://yandex.com/images/search?rpt=imageview&url=" + url);function numberImgs() {var imgs = document.getElementsByTagName("img");for (var img = 0; img < imgs.length; img++) {var parent = imgs[img].parentElement;if (!parent) continue;var numberDiv = document.createElement("div");numberDiv.innerHTML = 1 + img;numberDiv.className = "tmpImgNumberDiv";numberDiv.style.position = "absolute";numberDiv.style.padding = "2px 9px 2px 6px";numberDiv.style.background = "#f00";numberDiv.style.color = "#fff";numberDiv.style.zIndex = "9999";numberDiv.style.lineHeight = "normal";parent.prepend(numberDiv);}setTimeout(function() {var imgNumbers = document.getElementsByClassName("tmpImgNumberDiv");var idx = imgNumbers.length - 1;while (idx >= 0) {imgNumbers[idx].remove();idx--;}}, 5000);}})();
  The 5 searches it launches are (replacing XXXX with the image URL):
  Google: https//lens.google.com/uploadbyurl?url=XXXX
  Bing: https//www.bing.com/images/searchbyimage?cbir=sbi&imgurl=XXXX
  TinEye: https//www.tineye.com/search?url=XXXX
  Yandex: https//yandex.com/images/search?rpt=imageview&url=XXXX
  SauceNAO: https//saucenao.com/search.php?url=XXXX
