Good Firefox extensions?

I just switched over to Firefox from Brave and I'm really liking it so far. Any essential extensions I should get or settings I should tweak?

    Let's see what's built up in there since I switched from Chrome when Quantum was released.

    • Decentraleyes keeps a local cached copy of most external script resources that are commonly used across large numbers of websites. This means you don't have to download the resources over and over, and also means the websites can't track you every time you access one of their scripts. Good for both privacy and speed.
    • uBlock Origin blocking the vast ocean of shitty advertising that has infected the internet. Surf like it's still 1999.
    • uMatrix is basically a firewall for your web browser, preventing pages from loading anything coming from external sources unless you explicitly grant them permission to do so.
    • Dont Track Me, Google cleans up all of the URLs you use when interacting with google. I installed this less for the 'tracking' aspect and more because I don't want to deal with google's bastardized URLs in search results and when copying links.
    • Skip Redirect prevents a lot of annoying redirect/reload behavior used by bad designers and invasive assholes. It can break sites, but there's a whitelist feature to fix that issue. I rarely run into any problems using it.
    • HTTPS Everywhere makes sure you only communicate securely with websites.
    • Gesturefy enables mouse gestures, including rocker gestures. If I have to touch the keyboard to activate a browser feature/function I consider it a failure of imagination.
    • Open With is a handy little tool that lets you launch external programs from within Firefox and pass them data from the browser as part of the launch parameters. I use this to launch youtube-dl and download any video/audio source with a right-click. Takes a bit of fiddling to set up.
    • Fireshot for taking screenshots of entire web pages easily.

    I have a few loaded just for reddit as well...

    • Old Reddit Redirect will permanently lock you out of the new interface and switch back to the old one every time reddit tries something to force you into the new design. Install this and it's 2010 again.
    • Moderator Toolbox for interacting with reddit's moderation capabilities and extending them into something less-shit than the default UI provides for us. It's also handy for combing through a reddit user's history.
    • Reddit Enhancement Suite, reddit without this tool cleaning, filtering, and extending features is intolerable.

        It was having issues with large pages (think like 20+ vertical) that fireshot was working around. I haven't checked in a while, those issues might be fixed by now.

        One of the feature of the DDG extension is that it enforces HTTPS connections, so if you have the extension you don't need HTTPS Everywhere.

    Since plenty of people have covered the basics already (uBlock, uMatrix, HTTPS Everywhere, Password managers, reddit related ones, etc) I will just list some of the more obscure ones I have installed that I still think are essential.

    Bypass Paywalls - does exactly what it says for tons of of news sites, but unfortunately was recently removed by Mozilla for "violating ToS" (but can still be installed manually with the XPI file)

    Don't touch my tabs! (rel=noopener) - "Prevent tabs opened by a hyperlink from hijacking the previous tab by adding the rel=noopener attribute to all hyperlinks (excluding same-domain hyperlinks)." Why that isn't default behavior I honestly don't know but I am extremely glad this add-on exists.

    View Image - "Re-implements the google image, "View Image" and "Search by Image" buttons." Because fuck you, Getty Images.

    Address Bar Subreddit Shortcut - "Allows one to go directly to a subreddit on Reddit by simply typing "/r/[subreddit]" (where "[subreddit]" is the subreddit name/slug) into the address bar."

    Tridactyl - "Replace Firefox's control mechanism with one modelled on Vim." Great for keyboard navigation while browsing.

    Tree Tabs - Vertical tab manager. Great for if you browse like I do with a bajillion tabs open at all times and also great for if you remove the top tab bar using userchrome.css like I did as well. Tree Style Tabs is also great but I prefer the cleaner look and added tab organization related features of Tree Tabs.

    Rename Tab Title - works great with Tree Tabs to keep things even more organized.

    Simple Translate - I was desperately missing this feature coming from Chrome since I require it so frequently and this is by far the simplest and most convenient one I could find for Firefox.

    YouTube Classic -Automatically disables YouTube's Polymer Web Components, which the new design uses. Ever notice those grey bars instead of text when you first open YouTube and every time you open a video? This gets rid of that garbage and makes everything load as plaintext again. It also tightens up the whitespace significantly so the site doesn't feel like it was designed with tablets taking priority over desktops anymore.

    Video DownloadHelper - Does what it says and even works on sites that use sequentially loaded segmented videos in an attempt to prevent you from downloading them as one complete video file.

    Stylus - "Easily install custom themes from popular online repositories, or create, edit, and manage your own personalized CSS stylesheets." Not obscure but absolutely essential, IMO, and I have yet to see it mentioned. It's how I make Tildes look like this: https://gitlab.com/Bauke/styles/tree/master/css/tildes-dracula#screenshots <3 @Bauke and his Dracula Theme

    And finally Tildes Extended - Adds some nice features to Tildes, which I honestly can't live without, e.g. a floating "Back to Top" and "Next New Comment" button that takes you to the next newest comment in a topic. Thanks again for making it @crius, <3 you too. :)

      Wow, moved back over to Chrome after an extension like Vimiumfx (not sure if that's actually the name... blurry memory, haha) announced that it would no longer be maintaining itself and posting updates (along with many other extensions but that one was the most important for me) following some Firefox browser extension update. I had tried other similar extensions, but they just didn't cut it for me. It's my first time hearing about Tridactyl, though! Would love to give that a shot!

    Among what everyone else has already said, consider using a password manager and installing their respective extension. For example, I use LastPass and have their extension installed. The extension typically auto-inserts your login data so you don't have to retrieve it manually all the time. Makes it a lot easier for me to make use of unique secure passwords for each website, instead of using the same exact (or slightly modified) password that is literally only a six-letter word + a letter + a number (still surprised that sucker was never cracked).

        First picture is the "normal view" when I'm browsing around - a strange empty box sitting up there (I imagine it's the "console box" which is likely normally hidden)

        Second picture is what happens when the console is activated. Also, all F-based find functionality is absurdly broken on the website (with the letters being rendered, but places all over the webpage in un-intuitive locations).

    I'm going to put in my list while trying to omit ones that have already been mentioned. Here goes:

    • Multi-Account Containers - an absolute must if you care about privacy and don't want other websites snooping on your activity.
    • Disable WebRTC - personally I haven't found a need for WebRTC and I'd rather not have my IP address leaked by some nosy ad
    • AudioContext Fingerprint Defender - Stops tracking based on audio fingerprint
    • Canvas Defender - stops tracking based on canvas API
    • Hbomb YouTube Censorship Addon - so if you're the kind of person who watches lefty youtube channels but then has their YouTube feed bombarded with right wing videos that you prefer not to watch, then this is the addon for you.
    • No Coin - stop those javascript bitcoin miner code from running up your electricity bills
    • Reddit Masstagger - ever feel like you're reading a brigaded thread and want to confirm if is from the types of unsavoury people you expect? Want to know if you are wasting your time arguing with someone who claims they are open minded but really just want to waste your time by repeating the same points over and over? Or are you just curious how much reddit has gone to shit? This is the extension for you. My only gripe is that I wish this could be embedded into mobile apps.

    For the devs amongst us:

    I have more, but I don't really see them as being too useful - it's more random stuff that I find interesting or whatever. Also, if anyone has a good tool for translating the entire page into English, I'll be forever grateful. I would prefer it not going to Google, but at this point I'm not going to hate.

    I can't thank @Deimos enough for having introduced me to LeechBlock. It's saved so many hours of my day. In a nutshell, it can block whatever website you choose to, for whatever period of the day. My config is here; basically, I'm allowed to browse Tildes, Youtube, HN & Reddit for an hour between 8pm--midnight, but I can see if I have any messages or updates from these websites anytime I want. But because I can’t browse for a long time, I can’t make many comments, and have too many comments to respond to, and thus that doesn’t ever consume too much time for me. I can also do whatever I want on Saturday. On mobile I don’t have this extension, but then I hate typing on mobile, so that’s not a problem too. This has been one piece of software that has made a big change to my life.

    FWIW here is the projects Github page, it is OSS w/ MPL. I was concerned when I first learned about this because I couldn't access the source code through the website, and thus I started using it a week later than I normally would.

    Greasemonkey is great software. It is one of the things that makes Firefox come closer to being "free software" indeed. You can run JS on websites you browse to modify their looks.

    With Redirector you can set redirects on URLs that match given globs or regexps. For example, I use it to redirect all reddit.com to old.reddit.com.

    Zotero and Zotero Connector are very useful for managing your archive of documents and other research material. With the connector, you can import PDFs, web pages and other stuff directly from Firefox.

    Recently made the switch from Edge myself. Depends on what you'd like to be able to do.

    Here's what I have installed:

    • Dark Mode - make websites more eye-friendly at night (NOT just a dark theme, it changes website colors)
    • Enhancer for YouTube - makes YouTube more usable
    • New Tab Override - if you aren't a fan of Firefox's new tab page (they removed the ability to change it, so you need an add-on now)
    • uBlock Origin - great for ad blocking
    • Honey, Personal Shopping Assistant - track prices of items across the web and find promo codes (Honey)
    • Google Scholar, Mendeley - for finding and citing research papers
    • Reddit Enhancement Suite - if you still use Reddit (I sure do)
    • KeePassHttp Connector - for integration of KeePass password manager

        I tried to like it basically since its inception. It helped that Microsoft is essentially paying people to do it (part of Bing rewards) and the add-on library is growing. It performs better than other browsers on devices with limited RAM and it works great with touch. I ended up switching because I was just tired of it feeling like a perpetual beta with occasional mis-rendered sites and random crashes. I think when it is mature it will be a good browser. They also just announced a switch to the rendering engine that chrome uses, so that should help (though people say it gives more power to Google within the internet).

    The list of extensions mentioned here is already pretty comprehensive as I'm kind of late to the party but a few I haven’t seen mentioned which I find, maybe not essential, but pretty handy are:

    • BlockTube - Used to block and hide single videos or entire channels from YouTube. I have over 1300 channels blocked as of this moment and can’t fathom using YouTube without it any more. You can also blacklist words/phrases to automatically block any videos that feature them, which is a nice addition. I'm still yet to find myself missing seeing any videos with the terms ‘haul’ or ‘hustle’ in them!
    • Absolute Enable Right Click & Copy - Does pretty much what the name says it does. It forces the removal of copy text protection on websites that disable the context menu. Not something that you encounter all that frequently nowadays, but very useful the few times you do.
    • Print Friendly & PDF - Creates a printer/PDF friendly version of a web-page with some simple customisation options to remove unwanted text, adjust the sizing of content etc. Not sure if this one counts as a real extension as I think it just redirects to their website but it’s useful enough to me that I figure it’s worth mentioning.
