danielson clicking on x to close seems to take a little while to happen compared to Vivaldi and other Chrome-clones

kyrios gave the solution here

You can go in Add-ons -> Languages and disable the languages packs you don't need. It's annoying but you only have to do it once.

kyrios - excellent point? 😄
Was wanting to post that but had to step out on an errand.
So, here it is (even if from another thread):

Firefox:

In the URL bar type about:config and press enter, then agree to the accept the risk warning.
Search for and double click these values to toggle (enable / disable) where appropriate.

Enable hardware acceleration in Firefox
layers.acceleration.force-enabled

Enable autoscroll
Use middle mouse button to click and scroll with mouse movement.
general.autoScroll

Disable Firefox Pocket
extensions.pocket.enabled

In KDE is a dark theme causing forms on websites using firefox to be dark?:
Create a new string pref in about:config (right click menu) named widget.content.gtk-theme-override and set the value to a installed light theme (e.g. Breeze), then restart Firefox.

    Again, doesn't just apply to KDE. 🙂

      EbonJaeger -thank you.

      Btw, think i've learned more useful Firefox tweaks here in a few minutes than a few years on Mozillazine.org (or elsewhere for that fact) ! 😀

      sangheeta Improve the speed of the scroll, the harder we scroll, the faster we go:
      mousewheel.acceleration.factor = 20
      mousewheel.acceleration.start = 1

      I've just set
      mousewheel.default.delta_multiplier_y
      and mousewheel.system_scroll_override_on_root_content.vertical.factor
      to 240.

      Your method seems better, thanks! I found 16 to be more suitable for acceleration factor, though.

        You're welcome, I found this setting a little by chance because the solutions proposed on the internet were not conclusive. Finally these two lines do the job.

        JoshStrobl Firefox is not better in terms of privacy and open source stuff? I'm not suggesting, I'm really asking... one of the reasons i give privilege to Firefox is that i felt like it's better related with open source world.

          RLFontan In theory. In practice, I don't really trust Mozilla anymore. Especially after their ways of running tests on unsuspecting users. Sadly I suspect Firefox privacy is a bit of a sham these days.

            EbonJaeger -can't be any worse than Google Chrome or future Microsoft Chrome-Edge or whatever they'll call it. Hey! I know, they're going to call it Outlook III.

              In terms of performance, i had a best time with Chrome based browser, but i just try to help those aligned with open source and privacy the maximum i can.

              One feature via an extension i used a lot for a while, was the ability to autohide the toolbar.
              I've grown accustomed to doing without (Slimjat has it natively).
              Do like most Chrome-based browsers but Firefox usually handles everything pretty well.

              True; though even I wouldn't put Microsoft in the same boat as Google. (I actually like Edge, more or less. You may call me a heretic now. xD )

              Edge is fun too!
              Don't want to start a browser war.
              Just feel it's good to have an alternative to the dominant Chrome world.
              What happens if Chrome or Chromium take you down a road you don't want?
              Like a driverless car that decides to roll you over a cliff because its GPS tells it the road is still there!


              Do miss a "close tabs to the left" option in Firefox.

                EbonJaeger It's a pity to think like this, even if I understand that kind of reaction. Mozilla is not perfect but the foundation a very active in the domain of privacy protection.

                Chrome. It's the best tool for the job (my opinion), closed source isn't as important to me as fit-for-purpose.

                Note: I use Firefox at work.

                JoshStrobl Use Vivaldi at work till it crashed twice in the same day, losing all my work (working on a wiki). Since then, vivaldi is my second browser. Mozilla is again at the top because it's rock solid.

                Improve readability of the bottom left url popup using userChrome .css
                with white font color on black background :

                #statuspanel-label,
                statuspanel[type="overLink"] #statuspanel-label,
                statuspanel[type="status"] #statuspanel-label[value^="Looking"],
                statuspanel[type="status"] #statuspanel-label[value^="Connect"],
                statuspanel[type="status"] #statuspanel-label[value^="Waiting"],
                statuspanel[type="status"] #statuspanel-label[value^="Transfer"]{
                  background-color: #111 !important;
                  color: #fff !important;
                }
