Question about Apple MacBook Air
I have 8 desktops on my mac. Very often, when I three-finger swipe from, say, desktop 1 to desktop 2, the screen goes to desktop 2 but then immediately jumps to, say, desktop 6. Why is it doing that and how can I fix it? FYI, it only recently started this behavior. It used to work as expected; desktop 1 to desktop 2 or desktop 5 to desktop 4. Thanks!
I'd try adjusting your setting in
Not sure what key combination can affect those settings.
If that does not help try resetting the PRAM and or the SMC.
Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.
you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.
Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons
Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:
* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc
* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc
* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc
* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc
* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc
So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery
This is how to reset SMC on most modern Mac laptops:
Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual
Here's the key sequence to hold down:
Reset the SMC of a MacBook Air or Retina MacBook Pro
Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini
Resetting SMC is different for non-portable Macs:
Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual
Reset the SMC of a MacBook or MacBook Pro's with detachable batteries
mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:
Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual
Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.
Happy New Year,

SOURCE: Using the trackpad with firefox
Mozilla has been working on getting this added into Firefox so that you may not have to employ any of the below solutions.
SideTrack is one possible solution, the only concern may be you are actually replacing Apple's own driver with theirs.
A less intrusive approach would be to use MultiClutch which is a standalone application that allows you to customize how the trackpad behaves with the applications of your own choosing.
Changing just one of Apple's default settings for the trackpad will allow you to right-click.
Apple has not release the application interface code to 3rd party developers, so companies like Mozilla are having to reverse engineer in order to figure out how to make their applications utilize these new features. It is Apple's way of trying to steer you towards only using their own applications.

Yes, this can be fixed without losing all your files, but the more you play with it the less chance there is.
If I had your machine in my shop, I would boot it while holding down command-V. This causes a raft of diagnostic information to fly by on the screen. At the end, I would hopefully see something in the sequence that I would recognize as abnormal, possibly an error message explaining that some part of the boot sequence failed. The problem here is that you have to have enough experience to recognize what is normal and what isn't, because there are a lot of error messages that happen every time and mean nothing. Having located the problem, I would boot into single-user mode and move whatever was failing out of the way so it would boot properly, then replace that portion once we had gotten the machine up.
Since the average user is unlikely to be able to use this approach, I would recommend reinstalling the system with "Archive and Install." This replaces the operating system, but NOT your user files. If you have upgraded your OS since the gray install discs (and you almost certainly have), I would run the installation from the newest OS DVD you have. Warning: you MAY lose third-party applications (Microsoft Office, games, etc.) which you will have to reinstall from their original discs.
