Ihave a Mac Air laptop, running Lion OS-10.7.1) I have downloaded Firefox(6-2.02.dmg to desktop, and put it in Applications,but it will not open or go into Dock.

That is all I can tell you. I like Firefox...does it work with this Lion??

I just downloaded the FF 7.0.1 .dmg file from here using Safari.

Select the language you want and use the link in the middle column.
If you tried to install Firefox in the system Applications directory, did you type in your admin password to get it to go in? Adding anything to that directory requires me to enter the admin password. Mind you, I do not install Firefox in there. I set up another Applications directory in my standard account and then created subdirectories for various categories in that. That is where I install Firefox.

    Firefox is freezing in the middle of a browsing session. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox to still be running. Once I close Firefox in Task Manager, I can re-start Firefox. This can happen several times in the space of a few hours? I'm running Vista Home premium with Firefox 3.6.16, and this problem has only started in the last 4 weeks. Can Anyone Help? Core 2 Duo E7300 with 4GB RAM.

    Sounds like it is hanging when you exit and later try to restart Firefox.

    ***Firefox 4 users, hold the Shift key while clicking the Firefox 4 desktop icon to enter Safe Mode.
    ***Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox.

    *** If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it
    ***#by enabling '''<u>one at a time</u>''' until the problem reappears.
    ***#You can also enable a few at a time (3-5), keeping track of what you just re-enabled to see if the problem re-occurs; this will help narrow down the possibilities if you have a large number of add-ons.

  • I can connect my tc to the internet and back up my iMac, but it will not back up my mac book pro... ANY thoughts?

    i can connect my tc to the internet and back up my iMac, but it will not back up my mac book pro... ANY thoughts?

    When I go to connect my MBP, it says I have the wrong user name and/or password; however the names and password are the same on both computers.
    The MBP connects smoothly to the internet, just not the TC.
    Does this help?
    There is no login name required to get internet unless you are running a vpn or pppoe client.
    The wireless uses a security key.. but that is fixed in the wireless setup.. so no user login should be required at any time.
    It sounds to me like you have the wrong setup.
    Please do a screen shot and post it of the imac setup that works.. show us the airport network with its ip address and where you are putting in the login.
    Please also do a snapshot of the TC and how it is setup.
    What broadband do you have?
    Is the TC a router or bridged?

    Sometimes the App Store version doesn't work correctly. In this case, install 10.8.4 with the Combo version > http://support.apple.com/kb/DL1659?viewlocale=en_US&locale=en_US
    The Combo installer is the safest way to update OS X, and it allows you to update more than one computer with a single download

    iOS: Device not recognized in iTunes for Windows

  • HT4943 My magazine will not open on iPad.  It will open on iPhone. Tried deleting on iPhone, but still will not open on iPad. Running latest ios6.

    Magazine ( Dirt Bike mag ) will not open on iPad.  It will open on iPhone. Tried deleting on iPhone, but still will not open on iPad. Running latest ios6.  Used to work on iPad. Seems to try to open then goes back to main iPad screen. Perhaps began acting up when updated and cleaned up iPad or when recently installed on iPhone5. It works on iPhone now, but no longer on iPad. Deleted from iPhone, but still no workie. Downloaded from cloud back to iPhone. Works there, but not iPad.

    What are the attachments? If they're a file type the ipad can't natively open then you could have issues and may need an app to handle them.

    Let's try a repair install of iTunes.
    Restart the PC first.
    If you're using Vista or 7, now head into your Uninstall a program control panel, select "iTunes" and then click "Repair".
    If you're using XP, head into your Add or Remove Programs control panel, select "iTunes", and click "Change". Select "Repair" and click "Next" as per the following screenshot:
    Can you launch your iTunes now?

  • I am running Mac OSX Panther and Firefox 2.0.0.8. I want to use Intuit tax on-line and was told to update to Firefox 3.o. Downloaded 3.o(2) but it will not open. Help. Newton

    Have tried twice to download 3.o and 3.0(2). When I click on the disk image, the icon bounces once or twice, but nothing happens. I have tried placing the old versions in trash, but this did not help.

    Sorry, Firefox 2.0.0.20 was the last ever release for Mac OSX 10.3.9 and earlier versions. You can get it here, but that isn't going to help you for websites that require a Firefox 3.0+ version. You're going to have to use a different browser that's compatible with that web site, or use a newer computer that has a newer operating system to be able to install a newer version of Firefox. <br />

  • Windows will not open with Nano in dock/charger?????

    Hello to all.
    This is first mp3 player and have not had a great experience so far. Technically this 2nd Gen 2G is my second one, the first was immediately returned to store becoause of problems.
    Anyway, now my computer will not get past the first black screen where it checks it's drives and OS. It sees the primary and locks up. If I turn it off and disconnect the iPod and re-start, everything runs like it should.
    I first discovered this with my 1st 2G and thought it was part of the problem. I was just leaving it plugged in with the USB charger cord when I turned off my computer in the evenings. I found a cool little charging dock with an RCA jack to plug into my bookshelk system by my computer. Still does the same thing! Downloaded iTunes 7.0, but still having the same problem!
    This is my first experience with mac/Apple and so far between the PITA software, difficulties I am having with the Music Store, (another issue), and this start up problem, I ain't impressed!
    Any help to ease my frustrations would be greatly appreciated. Thanks in advance.

    If you're not even booting into Windows, updating iTunes won't make a difference (as you've found out). What it sounds like to me is that your computer is trying to boot off your new Nano. Many newer computers allow booting off USB devices. It's possible (especially given the way you have explained the problem) that your computer is set to boot off of either external or USB devices first. This would explain why you had the same problem with your previous iPod. Do you know how to enter the BIOS in your computer? Usually when you first turn on your computer, it will flash hit F2, F10, Delete, or something like that in order to enter setup. You should be able to find something related to the boot order. You want to set it to boot from your hard drive first (or CD drive if you want... but then be sure your hard drive is next).

  • Downloaded dw to new laptop but it will not open

    bought a new laptop as old one died. Logged into the cloud but dw sub is not showing on acc. downloaded dw says its downloaded but no desktop icon and can not open it. Tried all browsers etc. is the quickest way to phone up and cancell old sub then just start afresh

    I'm not sure why you'd be opening a browser to try to open Dreamweaver. If it is showing as downloaded and installed in the Creative Cloud Application, you would need to create an icon on your desktop from the program file itself (not sure why Adobe apps don't put them on the desktop automatically).
    Go to Program Files (x86) > Adobe > Adobe Dreamweaver CC > Dreamweaver.exe
    On a Mac, it would be in your Applications folder.
