    This is answered in the bug report that you quoted one post above this...

    The issue is that skia draws in process whereas cairo draws predominantly in the X server. The issue is that the gtk2 widgets live in the X server. If we use skia for content then we need to read back the gtk2 widgets from the X server to composite them with skia. This adds a big overhead to every composite cycle.

    The net result is that regular browsing is slower with skia but benchmarks may show a faster result.

      Firefox doesn't, and never has, used MySQL - the very idea would be absurd. I suspect you're thinking of SQLite, which is a simple embedded SQL database.

      Nostalgia is a wonderful thing, but often misguided. Firefox 3 might have faster startup times, but in terms of page rendering performance, it's notably slower. It's also lacking in support for a lot of new CSS and Javascript operations...

        I don't have the bug #. I currently use GTK3 build Nightly release Mozilla/5.0 (X11; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0
        for Fedora 20 and noticed no issue with scrollbar using default setting.

          I just need to know how to disable the anti-social API completely.

            I don't know if that's an option, but to disable REALLY completely an API, the obvious choice would be make it in build time.

            Anyway, my guess is that setting social.enabled to false in about:config. It's false by default in my nightly install, so I'm not sure.

              I really don't like Chrome at all and last but not least for privacy concerns.

              If you like Firefox but it's sluggish on your system, then I'm here to help. To be positive Firefox (26) runs blazingly fast on my rather old system (AMD San Diego, Single Core 2.2GHz, ondemand, 2GB RAM, Nvidia GT 520 with nouveau driver). Running on ubuntu 13.10 saucy 64bit.

              But you need to tweak it a little bit in about:config

     = skia,cairo
     = skia,cairo
     = true
     = true (<== you don't need this one explicitly, because it's automatically set)
     = false
              gfx.xrender.enabled = false (important!)

              webgl.prefer-native-gl = true

              layers.acceleration.force-enabled = true
              layers.async-video.enabled = true
              layers.offmainthreadcomposition.async-animations = true
              layers.offmainthreadcomposition.enabled = true
              layers.offmainthreadcomposition.testing.enabled = true (optional, try on/off)
              layers.use-deprecated-textures = false (important!)

              browser.sessionstore.interval = 900000 (something very high. I have my setting at 900000)

              environmental variables
              (put them in your ~/.bashrc or in /etc/environment)
              MOX_X_THREADSAFE=1 ("MOX" is not a typo)
              MOZ_ACCELERATED=1 (needed in Debian, not necessarily in ubuntu, but it can do no harm)
              MOZ_DISABLE_CRASHREPORTER=1 (this does make a difference for me, but maybe it's just subjective)
              MOZ_DISABLE_PANGO=1 (optional, not so sure if it still gives some benefit)

              The output in the Graphics section in about:support should be something like the following now:
              Adapter Description: nouveau -- Gallium 0.4 on NVD9
              Device ID: Gallium 0.4 on NVD9
              Driver Version: 3.0 Mesa 10.1.0-devel
              GPU Accelerated: Windows 1/1 OpenGL (OMTC)
              Vendor ID: nouveau
              WebGL Renderer: nouveau -- Gallium 0.4 on NVD9
              windowLayerManagerRemote: true
              AzureCanvasBackend: skia
              AzureContentBackend: none
              AzureFallbackCanvasBackend: cairo
              AzureSkiaAccelerated: 0

              My xorg.conf for nouveau driver (Firefox still is fast if you enable Compositing and AIGLX, but I just use openbox)
              Section "ServerFlags"
              Option "DRI2" "1"
              Option "AIGLX" "0"

              Section "Device"
              Identifier "NVD9"
              Driver "nouveau"
              Option "GLXVBlank" "1"
              Option "SwapLimit" "2"
              Option "PageFlip" "1"

              Section "Extensions"
              Option "Composite" "0"

              my glxinfo:
              direct rendering: Yes
              OpenGL vendor string: nouveau
              OpenGL renderer string: Gallium 0.4 on NVD9
              OpenGL version string: 3.0 Mesa 10.1.0-devel
              OpenGL shading language version string: 1.30
              OpenGL context flags: (none)

              man nouveau
     (most of the env variables)
     (very nice!)

              Hope that helps! And it can happen that you're driver is making problems. Or Firefox crashes. But I have no problems.
              If so:
              instead of
     = skia,cairo
     = skia,cairo
     = skia,cairo
     = cairo

              PS: This is all yet on Firefox *26*!

                Yep, they answered when I asked the same question there

                  Firefox needs 8-10 s to start here, and can stop responding during 1-2 s repeatedly while loading heavy pages (with many pictures IIRC), which is really annoying. I have a 3.2*GHz Core i3 with plenty of free RAM, swap is unused, firefox cache is disabled, so there is no obvious reason for Firefox to be so slow. Do I have plenty of extensions? Sure! But I need them?

                  I recently tried Chromium again but it stinks of Google marketing and is not usable as far as I?m concerned.
                  Yeah that bothered me quite a bit (responsiveness of new tabs while loading) but I found a tweak that works beautifully. Just go to about:config and create 'content.switch.threshold' and give it a value of '1000000'.

                    With this, it means that the Holly Nightly builds are no longer supported and I'm forced to use Australis. Shame.

                      My personal observations:

                      1. 285 354
                      2. 459 511
                      3. 223 281
                      4. 574 730
                      5. 224 306
                      6. 464 349 (!)
                      7. 228 263
                      8. 542 1175-985

                      cairo, skia
                      skia is slower 30% only in 6 test, but twice fast in 8.

                      1. asteroids bitmaps
                      2. asteroids vectors
                      3. asteroids bitmaps shapes text
                      4. asteroids shapes shadows blending
                      5. arena5 vectos shadows bitmaps
                      6. plasma math canvas shapes
                      7. 3d render math polygons image transforms
                      8. pixel blur get/put imagedata

                      Benchmark Score: 382
                      Average FPS: 8

                      Benchmark Score: 501
                      Average FPS: 11
                      with Cairo backend freezes, taking over 6 seconds till "script hangs".

                      with Skia
                      test1: 0.007s
                      test2: 0.015s
                      test3: 0.02s


                      Cairo: 920-835 points
                      Skia: 85 points

                      Cairo is crap, Skia beats it 2x-10x times in browsing experience and absence of lags.
                      Only place where Skia looses is MS Psychodelic.
