    I compared Mozilla's BananaBread and UE3 Flash (in Chrome, FF is still slightly slower)

    and BB was 2x faster;-)

    Do you need *.gif version?

        It seems like every release they say memory usage is improved but I don't see much noticeable change. It's starting to feel meaningless like how every Ubuntu release is said to be faster, smoother, have quicker boot time, feel "snappier".

          I don't think 15 really reduces memory use under "normal" situations, it just fixes a bunch of memory leaks that were created by a lot of different extensions. So if you used to have problems with Firefox leaking tons of memory over time, this may be the release that fixes it for you. But I don't think there's going to be much further reductions in the baseline memory use.

          In fact, I think FF15 is when compartment-per-global landed, so that probably increases the baseline memory use.

            I was recently in need for a modern browser on a very lowend machine - P4 with 512Mb. So, I had to compare Fx with Google Chrome/ium. I opened several websites and surfed a little, then let the machine stay for 3 hours. The results were astonishing - Fx-50MiB, Chrome-300MiB (up to crossing the 480MiB boundary total). I know that Chrome has a bit faster Javascript, but in terms of Ram usage Fx is clearly better.

              True, on my PC chrome 64bit opened with 20+ tabs and running for 4 hour can consume as much as 1.5GB ram. I switch to chrome from firefox 3.5 when I had a old PC but now Chrome is more Ram hungry then FF.

                The WebGL problems with FF were (or are) driver related right ????

                I remember they were only supporting blobs.

                  From the demo page:
                  Mesa on Firefox 15 on Linux does not support compressed textures, but it works in Firefox 16.
                  That's all, FF16 WebGL works fine (tested on R600g).

                    Blog post on Firefox 15 memory reduction

                    Hi guys, here's the blog post you want for explaining what's special about Firefox 15 with regards to RAM usage:
                    http://blog.mozilla.org/nnethercote/...-add-on-leaks/

                    If you'd like to see the progress being made on the Memshrink project (which aims to reduce memory usage), this is the blog to follow. It's updated every 2 weeks now with what's happened with the project.

                    The wiki page for the Memshrink project is here: https://wiki.mozilla.org/Performance/MemShrink

                      Hmm I hope it is much improved, I'd love to go back to using it as my primary. It's a lovely browser in many ways, just recently I was having issues with it using so much memory and causing my whole desktop to become sluggish so I've been using Chromium.

                        Good to know.

                        For mesa 8.0.4 on my 6850 when i run the Khronos tests with FF14 i get GPU lockups.

                          The support for ST3C with Mesa landed in Firefox 17 and has been backported to Firefox 16: https://bugzilla.mozilla.org/show_bug.cgi?id=774134

                            Also breaks WebDriver for Selenium 2.25.0

                            I find it hard to believe that Firefox 15's native events are that different from Firefox 14.0.1's.

                            Unfortunately for me, WebDriver support is a "must have" feature.

                              Something defiantly changed, FF14 on my android was barley usable, FF15 is pretty smooth, and more responsive. The only complaint is that not all text on sites like this forum, is being scaled the same.
