Mozilla Engineering Manager Benjamin Smedberg posted on the official Google Groups page that they will be ending the development of Firefox for 64-bit Windows. He cited the following reasons for this shocking decision.
- Many plugins are not available in 64-bit versions.
- The plugins that are available don’t work correctly in Firefox because we haven’t implemented things like windowproc hooking, which means that hangs are more common.
- Crashes submitted by 64-bit users are currently not high priority because we are working on other things.
- This is frustrating for users because they feel (and are!) second-class.
- It is also frustrating for stability team triage because crash-stats does not easily distinguish between 32-bit and 64-bit builds in the topcrash lists and other reports. We basically ignore a set of nightly “topcrashes” because they are 64-bit only. (See bug 811051).
According to Mozilla, about 50% of their nightly testers were 64-bit Firefox users and they are taking risk of losing most of them as Firefox users. Are you using Firefox still?
