Does this still happen with a more recent Nightly? Can you please provide steps to reproduce including a URL we can use to test? Does this happen with en-US builds? Are you using a localized version of Firefox? Are you using a localized version of ArchLinux?

It still happens with the latest Nightly (in fact, all version later than 12.0).
Both en-US Nightly or zh-CN Beta has this bug. I am using a localized version of Archlinux.

You can try on WebQQ(web.qq.com, a Chinese IM web app) or Renren(www.renren.com, a Chinese SNS). The bug may happen after input some Chinese.
I also try the other input method(ibus), the bug happen too.

So this does not happen with Firefox 11? If so, can you please try to trace down a regression range? If it happens in 12 but not 11, the regression is likely in one of the Firefox 12.0a1 Nightly builds. You can use the mozregression[1] tool to make tracking down the range easier by giving it to dates. 

Firefox 12 was in Nightly from 2011-12-20 to 2012-01-31.

I found that this bug may has been fixed on 2012-08-21, the bug hasn't appeared over 12 hours.
I remembered that on Firefox 12 Nightly i found this bug. But at that time i don't know why it appears. These day i found that it may appear with fcitx.

The bug appear on 2012-08-21, maybe it didn't be fixed.
I couldn't start Firefox 12 nightly(2011-12-20), it crashed.

Could be graphics related, I don't know? Moving this to Core::Graphics to get a developer's opinion.

Michael, can you please provide a copy of the Graphics section of your about:support page?

I'm confused -- your about:support page shows you are using an AMD graphics driver yet comment 6 shows NVidia libraries being loaded. Does your system have both (ie. an integrated AMD card and discrete NVidia card, or vice versa)?

Comment 11

[Michael Lin]

No, I only installed AMD graphics driver. I don't know why firefox want to load NVidia libraries.

Comment 12

[Joe Drew (not getting mail)]

The VDPAU thing looks like a red herring.

Comment 13

[Michael Lin]

Today a member from LUG answered me about this problem. There are something wrong with my input method config, but not the bug of Firefox. The bug disappeared while i use the right config.
I don't know why the bug happens with Firefox...
