How can I prevent sites displaying in bold font in versions of FF later than 3.6?

Many sites (google, gmail, wikipedia to name a few) are appearing in bold font when they should not be. This started for me in FF4, and has persisted in FF5 and now FF6. I'm running Windows 7 x64.

I've seen many replies to questions about bold font problems telling people to reinstall, e.g. arial as the problem is corrupted fonts on their system. I've tried reinstalling several fonts (arial, verdana, tahoma, times new roman...) and it doesn't solve the problem. Also, if I reinstall FF3.6, the problem goes away, so it seems to be an issue with FF and not my machine.

I've also tried running FF6 in safe mode, with addons disabled, and restoring the default settings. None of this has helped.

I should add that I have another machine running FF6 with the same addons, but with Windows 7 x86 - all pages display correctly. Is this a known issue for FF4+ on 64-bit systems?

Are you using the same profile (bookmarks, cookies, extensions) as you had on 3.6. Check your font settings advanced Tools > Options > Content against those of the machine that works.

Thanks for replying. I'm using exactly the same profile as I did in 3.6, and reinstalling 3.6 does solve the problem. I'd rather use the latest version though.

I've just checked Tools > Options > Content > Advanced of the two machines side by side, and they're identical. The 32-bit one is fine, and the 64-bit one isn't.

Which graphics display card to you have?

Nvidia GeForce GT 335M 1GB

I guess it's a hardware acceleration issue - running in Windows XP compatibility mode fixes it.

Edit: So does disabling hardware acceleration... :-) Any idea if they're planning on fixing this at any point or if it's worth submitting a bug report?
