In truth I really like rapid releases - for desktop software on home machines, and in development tools/libraries. Bugs in software I use myself I can work around or fix, or I can roll back to an older version until the issue is fixed in a later release.
It's only when I have my sysadmin hat on and am responsible for the reliability of a network of machines used by other people that I start to want stability and time to fix things before the next update breaks everything all over again. Even then, I still really like rapid releases ... it's only when they're accompanied by the total abandonment of any support for any older releases that they bug me.
I do think FF and Chrome may be rushing into the future a little *too* fast - not in the sense of improving too rapidly, but in being unwilling to keep a release or two around for at least security fix purposes.
