最新版的 Firefox 經常和 GPU driver 撞! 原來大家可以熄咗 Firefox 的 hardware acceleration 又不影響 fonts rendering!
(Linux 當然都適用!)

先去 Options -> Advanced -> General 熄咗 Use hardware acceleration when available! 然後用以下方法開 GFX DirectWrite:

Firefox issue: Poor font rendering in HTML5 reader

There is a known issue with the Mozilla Firefox web browser that prevents the ReadCube HTML5 Web Reader from loading on some computers. In particular, Windows and Linux systems are known to be affected.  If Firefox is not able to correctly recognize your graphics card for enabling hardware acceleration, a feature called DirectWrite is disabled. This in turn can affect font rendering. We want to ensure an optimal reading experience with the ReadCube Web Reader and therefore do not load in Firefox browsers with this disabled graphics state.

This is a known issue with Firefox and is not specific for the ReadCube Web Reader. Please see:

https://bugzilla.mozilla.org/show_bug.cgi?id=751083

It is possible to manually enable DirectWrite in Firefox. We provide the directions below but please note, this does not guarantee optimal font display and may affect browser speed. To manually enable DirectWrite font rendering in Firefox:

  • In the address bar, type "about:config" and press Enter
  • Search for the preference name: "gfx.font_rendering.directwrite.enabled"
  • Double-click on it, and set the value to "true"
  • Restart Firefox

If this does not help, please try another web browser (such as Chrome, Internet Explorer, Safari or Opera). You can also reach our customer support at [email protected]. Since this is a general known issue with Firefox, please direct any specific requests for information about the browser's hardware acceleration/DirectWrite settings to Mozilla Firefox support.

Update:
發現開咗 DirectWrite 會影響 Firefox 個 built-in PDF reader!

只有 Firefox 3x 和 Radeon driver 撞啦! 關咗 hardware acceleration 即刻無事! 玩 games 亦無事!
未試重裝 Win 8.1, 因為等緊 Win 10 upgrade! 不過應該無分別!

BTW, "撞"的意思兮 Firefox crash, 不是 GPU driver crash!
