Firefox 2.0.0.10 Gaffe Prompts Quick Fix

Advertisement (Why?)

Bug hunter Kevin Han posted an issue that was later labeled as severe, the bug causes certain images in a web page to be poorly represented.

The error concerns the representation of vector graphics using HTML and JavaScript. Firefox 2.0.0.10 reacts to the JavaScript method canvas.drawImage() with the exception of "NS_ERROR_NOT_AVAILABLE". The method drawImage() should render pixel images into vector graphics drawing.

The developers have already released an updated [nightly] build that fixes this problem, the Windows version can be found here, the Linux version here. The Mac build crashed in the MozillaAliveTest, the development team is investigating.

You can reproduce this bug by looking at http://www.foxsaver.com/public/published.

For Firefox 2.0.0.10, this shows the photos fine. However the title and photographer name are on a plain background, when instead, they should be on a background of a inverted copy of the lower portion of the photo.

If you see the plain white background, you have repro'd the bug.
If you see the inverted photo background, you have verified the fix!

I will wait for the official update btw guys, nightly builds are generally not for public consumption.

Is this related to or separate from the FF security vulnerability in this security advisory?

I'm guessing it's only related in that this security vulnerability was fixed in 2.0.0.10, wheras this bug first started to appear in it.

At a choice between a few random images not appearing correctly or a possible security vulnerability, I'll pick the dodgy images.

And like Neobond, I'll wait for an official update before I upgrade. I hadn't even noticed it and I've been using it for about 24 hours now.

Please do not upgrade to FireFox 2.0.0.10. A bug(Bug 405584 Canvas.drawImage method is not working) is causing FoxSaver not showing pictures. You can download a 2.0.0.11pre release from FireFox nightly build here: Linux, Widnows.

causing FoxSaver not showing pictures ? I have Firefox 2.0.0.10 and I can still see the picture, just without the fancy white gradient under the labels, no big deal.

First time ever I hear about Foxsaver...

You really have to applaud Mozilla's quick response. One of the reasons I love firefox!

I only updated a couple days ago but when I reloaded yesterday it wasn't available to update

I think this "severe" bug is getting just a little overblown, myself. I haven't noticed any differences graphics-wise with Firefox since the 2.0.0.10 release.

I'm not saving it isn't a bug, I'm just saying it's not as important as some people are saying it is. IMHO, I can wait untill 2.0.0.11. If you're into using nightly builds, then that's great: go for it. Me, I'm sticking with 2.0.0.10 for now.

and here i was thinking IE 7 was the insecure browser

#8.1 Cryton on 29 Nov 2007 - 12:00

This isn't a security issue. It just stops some websites from behaving properly..

#9 +mrbester on 29 Nov 2007 - 14:06

I consider the placing of the text over the picture (great when it is a dark photo with dark text) should you not be running script a bigger gaffe...

Bugzilla comment: "The release of 2.0.0.11 is _tentatively_ scheduled for Friday 30th Nov. If that
comes off it'll be the fastest turnaround between Firefox releases to date (ie,
it relies on everything in the release process going without a hitch)."

I think I can reproduce the error as well on my site at http://perisic.com/canvasclock that should show the time (in figures) in the middle of the clock via drawString(). It should look somehow like that: http://www.youtube.com/watch?v=HRkr1GkpJvk Since 2.0.0.10 the figures don't show.
