We’ve all turned off trimURLs but what else is hiding in there?

      Thanks, I need to remember to do this tomorrow.

      Just had to entirely do a fresh install like 6 hours ago.

      I looked up “pocket.enabled” in about:config, but there wasn’t an entry by that exact name. There was “extensions.pocket.enabled” though. Is that the same?

    Setting full-screen-api.warning.timeout to 0 removes the notification at the top of the screen that tells you how to exit fullscreen mode.

    For me:

    browser.ctrlTab.recentlyUsedOrder: False

    browser.tabs.insertAfterCurrent: True

    dom.popup_maximum: 100

    browser.download.improvements_to_download_panel: False

      browser.tabs.insertAfterCurrent: True

      I use this too. Great feature for tab hoarding keyboard warriors like me. Use Alt/Cmd + 9 to jump to the last tab.

      dom.popup_maximum: 100

      What does that do?

      browser.download.improvements_to_download_panel: False

      Why?

        I have my default Download dir set to /tmp anyways, which practically also makes the browser do that I believe.

    browser.tabs.tabmanager.enabled -> false
    It removes the tab manager. The down facing arrow next to the minimize button at the top right.

    extensions.pocket.enabled -> false
    Disable Pocket

    identity.fxaccounts.enabled -> false
    Disable Firefox account

    media.autoplay.blocking_policy -> 2

      The firefox account is actually neat. It syncs bookmarks, history and passwords between desktop, phone, laptop or wherever you use firefox.

        I manually backup my bookmarks. Firefox is set to delete history when I close it. For passwords I use KeePassXC.

        It might still be useful to turn it off in some scenarios. For example you might not want firefox bothering you with the account on work PC where it might be against company policy to use the cloud sync.

        media.peerconnection.enabled it disable WebRTC.

        browser.tabs.tabmanager.enabled it removes the tab manager. The down facing arrow next to the minimize button at the top right.

          media.peerconnection.enabled it disable WebRTC.

          Why would you want that? Doesn’t that block you from using basically any online call?

                WebRTC leaks your IP allowing third-party websites to exploit the WebRTC in your browser to detect your real IP address and use it to identify you.

                You still can use desktop apps to do that.

            Personally I have a separate Ungoogled Chromium installation for online calls, since some of those call/conferencing services kick up a fuss when launched inside Firefox ☹️

        You can enable auto play on twitch only. By going to Settings > Privacy & Security > Permissions > Autoplay > Add Twitch and set it to Allow Audio & Video > done.

        You have to click the play button to play the video. If you set it to 2.

        EDIT Here’s a Mozilla wiki article about it.

        EDIT 2 You’re talking about media.autoplay.default. That controls if autoplay is on or off and what is blocked, Audio only or Video & Audio.

    I like resistFingerprinting = true but it may be a bit much for some people. You lose some keyboard hotkey capabilities in RES and all your windows always open at a certain size upon relaunch/new window.

    I have a slow connection, so privacy.partition.network_state = false was a game changer. It prevents firefox to re-download an image (or video, or whatever) when you open it in a new tab (State Partitioning in Mozilla docs).

    Warning: the main goal of State Partitioning is to prevent cross-site tracking, so this option will make that easier. In my case it’s worth it and I mitigate that by other means, but you should be aware of it.

    Not obscure but general.smoothScroll.msdPhysics.enabled=true is a must have IMO.

        You have to actually toggle to see it but IMO it massively improves how scrolling feels.

        There are a few more scrolling-related options out there on the net if there’s a particular “feel” you want to go for. https://github.com/yokoffing/Betterfox/blob/main/Smoothfox.js provides a couple you can try out, and most of these custom scrolling options use msdPhysics as a baseline.

    dom.event.clipboardevents.enabled - block sites from preventing you using copy+paste e.g. in email and password fields.

    I’ve only recently started using this one, so ask me again in a couple of months if it solves the issue :] or if it has unwanted side-effects - I know at least it doesn’t prevent websites interacting with the clipboard entirely e.g. with a button to click to copy text to the clipboard

      Browsers changed this because people kept accidentally hitting it. I’m glad it’s gone. My mouse has back/forward buttons on the side and I remapped those to go back and forward in browser history.
