Print preview hangs on one wiki page
On this page http://en.wikipedia.org/wiki/Comparison_of_audio_formats selecting Print Preview hangs FF. I'm running 20.0.1 on Win 7. Tried loading FF in Safe (addons disabled) Also hangs on my XP machine. Never saw a hang like this before and was using print preview on other wiki pages just before this page hangs. Hang every time I try PP on that one page.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
- Go to Firefox > Help > Troubleshooting Information.
- Click the "Reset Firefox" button.
- Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
- Firefox will open with all factory defaults applied.
Further information can be found in the Refresh Firefox - reset add-ons and settings article.
Did this fix your problems? Please report back to us!
Thank you.
Not to be difficult, but before I take the chance to cause myself hours of trying to reconfigure back from reset, could someone try to reproduce? I count 3 mouse clicks to get to the problem.
1 - click -- http://en.wikipedia.org/wiki/Comparison_of_audio_formats , 2 - click file, 3 - click print preview
On two machines it hangs every time. Maybe it is the page, but maybe FF could defend itself better.
Yes, 35 minutes later, still not responding...
It's strange because Wikipedia generally has very simple print layouts. If I strip out the external stylesheets using the Web Console, the page previews almost immediately. To try that:
(1) Press Ctrl+Shift+k to open the Web Console.
(2) Next to the caret (>) paste the following line of script and press Enter:
while(document.querySelector('link[rel="stylesheet"]')){var s=document.querySelector('link[rel="stylesheet"]'); s.parentNode.removeChild(s);}
Of course, there's no way for a user to know in advance that this particular page will hang Firefox if you try to print it, and unfortunately I don't have the patience or tools to figure out why it's happening...
An alternative is to disable the stylesheets, then you can easily enable them (s[i].disabled=false; or just toggle)
var s=document.querySelectorAll('link[rel="stylesheet"]');for(i=0;s[i];i++){s[i].disabled=!s[i].disabled;}

Thanks, guys, for confirming I'm not the only one who might see this problem. Is this something that should be listed as a bug for possible investigation in a future version of FF? Is there a formal way to report it?
You can file a bug report here: https://bugzilla.mozilla.org/
Just to add a little more info...
The page is really too big to print well even if the css parsed ok.
I looked at one of the css files. It's one big text block with no human aids like line breaks. I ran one of the css files in verify at w3c and it gets over a hundred errors. I then ran a beautifier so I could look at it in a way that makes sense, which made it almost 2400 lines. A lot of the failures were from lines with "!ie" in them. I guess that's some kind of nonstandard kludge for Internet Explorer.
So a pretty ugly set of css for the browser to try to digest. Impressive that the display handles it as well as it does.
I'll try to file a bug as it would be nice if FF didn't hang.
I'm having the same problem on wiki, mainly on music discography pages (not all, but some). The print started hanging up this month (May 2013). The last one that I tried with a problem was Hoobastank's Discography page on wiki. I tired this on a Win XP SP3 and Win 7 64 bit machine.
