@lars

Blocking rendering until the fonts are loaded isn’t all bad. On FF I see my page re-rendering every time it loads, it’s really jarring. I may be a perfectionist but the effect is annoying enough to me that I disabled the font and just started using system fonts. In chrome the page may take a few extra ms the first time it loads, but after that I don’t get a jarring shift n every page load.

@Lars and @Rick: Can you devise tests, similar to UA Profiler, that could test web fonts and the SVG issue? If so, I could add them. @_ck_: Since webkit supports parallel script loading, it's less critical to implement DEFER. The way DEFER is defined in HTML 4 and HTML 5 is a little vague and differ slightly, but what WebKit does with parallel script loading could be considered an implementation of DEFER, so whether you add DEFER or not, that's what WebKit does. Now, none of the browsers do what I really want for defer - download everything else in the page first, then download the deferred script(s). I'll write a blog post soon about DEFER and two new attributes I propose: ASYNC and POSTONLOAD.

I have a large SVG application that runs fine on FFX 3.0.x However it is very slow on 3.5. Almost unusable.

I have three os’s and 5 browsers at my desk and across the board Firefox 3.5 has gone from decent performance to the absolute worst.

Currently Safari on the Mac is the best, elsewhere the other browsers all perform well running this SVG application.

Steve, did you notice that Firefox 3.5 finally supports DEFER on javascript?

Only took them nine years :-)

ps. do you know if webkit supports DEFER ? I have to assume it does.

Now that web fonts are coming, you might consider testing if a browser blocks rendering until fonts have been downloaded (Safari) or choses to give the user at least something to read, and then re-draws the page with the correct font (Firefox). Waiting for a blank screen on a slow connection sure is not a nice experience.

Did you know that Microsoft is stealthy adding some .NET plug-in to Firefox without our knowledge and without possibility to uninstall it?

Looks like the most recent nightly builds of Minefield gets all 11/11 tests correctly now.

Congrats Mozilla on being first to achieve this.

I agree with Raja MM, Firefox 3.5 for me is terribly slow and hangs all the time. Far more often and for longer than 3.0.11 ever did with the same extensions. It’s totally unusable and never should’ve been taken out of beta in its current state.

And to add insult to injury, for the first time now, even file save dialogs become unresponsive while Firefox is hung doing lord knows what. At the very least, under 3.0.11 when I tried to save an image, the file requester was at least responsive to clicking save.

Terrible terrible version. I’m going to try to downgrade back to 3.0.11 until this 3.5 mess is sorted out. Bummer dude. :(
