Created page with "Blocklisting graphics drivers is the process of causing Firefox to not use some or all of its hardware acceleration features on a given device, potentially for a limited set of d..."

New page

Blocklisting graphics drivers is the process of causing Firefox to not use some or all of its hardware acceleration features on a given device, potentially for a limited set of driver versions.

= Blocklisting Policy =
Graphics drivers can crash Firefox and/or your computer. Buggy drivers can sometimes crash in a recoverable way, but even these recoverable driver crashes can annoy users and cause other programs to misbehave or crash.

== Block Conditions ==
Acceptable reasons for blocking graphics drivers include:
* Firefox startup crashes
* Frequent (multiple times per day) recoverable driver crashes
* High crash volume inside the driver
* Severe performance impact
* Firefox drawing bugs caused by the driver

== Block Type ==
Drivers can be blocked via a downloaded blocklist or via compiled-in blocklist. The downloaded blocklist is carried as part of the regular Firefox blocklist ping, and as such cannot block startup crashes. The compiled-in blocklist, however, needs a new build of Firefox to take effect, which is much higher-cost and hence should be avoided whenever possible.
