Hmm. I see about the same thing with Chrome 35 dev and Firefox (28 or nightly) on Mac here, performance wise.

This was on Xubuntu 14.04 - Chromium was racking up score on random quite a bit faster than Firefox was. This is a squishy benchmark for all sorts of reasons ... but the difference was glaring.

It's entirely possible that platform-specific drawing paths matter here. :(

I can definitely see a difference on this one, yes, about 30%. A question. Does "rendering not included" mean not including painting times, or not including the canvas API call times either? My profiler is showing a bunch of fill(), rect(), stroke(), moveTo() calls dominating the wall-clock time, but I'm not sure whether those are what's being measured here or not.

That benchmark measures only the computation of the whole diagram -- which is the sole purpose of the library. The rendering, if any, is left to the caller after the diagram has been wholly computed, so there was no point for me to measure that part.

Gotcha. I filed https://bugzilla.mozilla.org/show_bug.cgi?id=985262 on this; if there happens to be a standalone version of this benchmark that skips all the canvas stuff that would be pretty helpful.

Eagerly waiting to ditch Chrome & its forced notifications. Perhaps with Australis (Firefox 29), the UI would be at par. Edit : Chrome feels subtle, lighter & perceptually faster (specifically : tabs, scrollbars). Although after updating Firefox today, I can notice that there's improvement in Firefox.

The first thing I look for in a browser is a way to switch through tabs in last-used order. If doesn't work out of the box, then I personally don't have a reason to investigate further. If this was a checkbox feature in Chrome (or Firefox, whichever's first), I'd probably never try anything else.

Is that feature being out-of-the-box, as opposed to available through an add-on, really that important? I love Tree Style Tab (https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta...), but I don’t really mind that it’s not built in to Firefox. It’s easy enough to install on a fresh computer, and the default tab bar is useable enough for short periods.

Anyway, as someone else said, setting browser.ctrlTab.previews to true in about:config should work. For me, it successfully changes the behavior of Ctrl-Tab to most-recently-visited order, and it causes hitting Tab while keeping Ctrl held to pop up previews of the tabs, just like Alt-Tab does on Windows. If you still can’t get that to work, there is also an no-restart add-on for what you want, MRU Tabs: https://addons.mozilla.org/en-US/firefox/addon/mru-tabs/.

From what I can tell about the exploits found at Pwn2Own, there were a total of 4 critical. Looks like FF28 addresses all 4. That was a very quick turnaround. The fact that FF runs in a single process seems to be a major security issue since the web views are not sandboxed. I know Mozilla is working on their multiprocess project Electrolysis https://wiki.mozilla.org/Electrolysis that is experimental in FF 30. Hopeful…

Unfortunately the bug reports are still 'secret' - https://bugzilla.mozilla.org/show_bug.cgi?id=982906

"The fact that FF runs in a single process seems to be a major security issue since the web views are not sandboxed." Only to people who don't really understand security. This whole "multi process" "sandboxed" meme started by chrome guys has really got out of hand.

I suppose I was mislead by the mozilla wiki link I posted which states at the top "The goal of the project is to run web content in a separate process from Firefox itself. The two major advantages of this model are security and performance. Security would improve because the content processes could be sandboxed"

> The fact that FF runs in a single process seems to be a major security issue since the web views are not sandboxed. Running content in multiple processes, by itself, doesn't help security at all. It does help stability , since if one process crashes the rest of the browser need not; that's particularly important if running plugins like Flash, which crash in a stiff breeze. But if untrusted content manages to exploi…

I suppose there would have been a better way to phrase that sentence. The goal of the Electrolysis is to render the web content in separate sandboxed processes to improve stability and performance.

I'm generally alright with add-ons that are Mozilla (or Google) 'branded', and those that are particularly well known otherwise. I also appreciate that the two you mentioned are listed as having been 'preliminarily reviewed' by Mozilla. I wouldn't go as far as to call the situation ideal though.

You're right about browser.ctrlTab.previews in any case - I must have only just tried option-tab, not restarted, or something similar when I responded to the other comment. How one is expected to dig up that option is a mystery to me though. Is it really such an unusual request?

Last version before they ruin their UI with Australis.

Best way to delay the pain (and that of their general too-frequent breakage) is to switch to the ESR version: https://www.mozilla.org/en-US/firefox/organizations/all/ , which should give enough time for addon writers to undo the australis damage.

Running in a single process (not strictly true; addons are in another) has a lot of performance benefits though. I can get Firefox up to ~1.2GB with a few hundred tabs; Chrome uses that much memory for about 20.

Also, splitting process is bogosecurity like "I run SSH on a non-22 port". I thought the general consensus here is that security by obscurity is bad.
