I recently upgraded my Firefox and it will no longer launch. I clicked to launch after install and it did not open and it does not open when I click in the icon.

I can't open Firefox.

From the menu bar, select
           ▹ About This Mac
Below the "OS X" legend in the window that opens, the OS version appears. Click the version line twice to display the serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.

  • HT3669 With recent upgrade to my Mac I can no longer get supply report on ink status in my printer-light is blinking and unable to tell which cartridge needs replacing?

    With the recent upgrade to my computer I can no longer get Supply reports from my printer:  a red light is flashing and I don't know which ink cartridge needs replacing?

    I happen to have an Epson printer as well - WorkForce 645 - that does show the supply levels.
    Since I have one, I know that Apple recently updated the Epson printer software (less than two weeks ago).  Do you have the latest software?  If not, you can get it through the App Store or here:

    Try it if you don't currently have it.  If you're not sure, you can download it - it can't hurt.

  • Lion and snow leopard bootcamp, after installing lion snow leopard bootcamp with windows 7 does not boot

    Just installed Lion OS  on my 2nd mac (on the 1st without an issue) but as I had a partition with windows 7 (installed with Snow Leopard bootcamp).
    It seems that Lion OS renamed the Bootcamp partition but I am not able to rename it through OS.
    Is there a solution for this or do I need to re-install?
    Many thanks for your help

    Hi Jack.........ok ive managed to create a link to that video on how to install bootcamp.....this is the tutorial i used and i managed to gain 100% completion on bootcamp 1st time no messing......like i said in my previous reply did you save the windows support files from apple....(Critical).....ok no point in messing about i suggest you start again from scratch........these are the things i used and YOU will need to complete bootcamp
    mem stick or cd-r / dvd-r......original copy disc of win 7 ...i never used an iso i used original disc....allow a minimum of 30gb of space for your win 7 partition.....if you want bootcamp so you can use big programs like windows based games i.e.....Crysis/Call of duty etc etc ..then you will need to consider that  you will need to allow a bigger partition to allow your HD to store the files.....this is the reason i installed bootcamp and so i made my partition    i have a 750GB HD so i made a partition of 300gb for windows 7 and left the other 450gb for Mac....so you need to partition enough for what you want bootcamp for remember once you get bootcamp working you will need to install ALL Important Windows updates Including Win 7 SP1......once everything is installed you will have bootcamp up and running lovely.....u can then boot up with either win7 or mac......click this link and watch carefully and do exactly as shown ok and you should be fine...if you have any probs contact me again ok.....let me know how you get on ok..:)...http://www.youtube.com/watch?feature=fvwp&v=QFIWtXTl4d0&NR=1

  • Printing from web pages is excruciatingly slow with most recent upgrades of Firefox .Use an iMac and an HP officejet printer. Printer works fine with Safari and woodprocessed files, but not with Firefox and web pages.

    Printing from web pages is excruciatingly slow since downloading most recent upgrades of Firefox Mozilla. I have a desktop iMac, OS 10.6.8, and an HP officejet printer 4500 G510n. The printer works fine with the Safari Browser and with woodprocessed files, but not with Firefox and web pages. Help please! It used to print fast with earlier versions of Firefox.

    Hello and welcome to the Apple Discussions Forum.
    I have hardly any experience with HP printers but since your posting has not been replied to yet I thought I'd offer some assistance.
    With the printer status and ink levels working, it shows that you have a connection to the printer. So I would look at the issue being with the protocol being used for the print queue on the Mac.
    Since you have XP and Vista working, I would check the printer queue configuration on either box. In XP, go to the Properties and select Ports. Click the Configure Port tab to view the connection. If you are using RAW, then this is known as HP Jetdirect-Socket on OS X. So if you are not sure what protocol was used before I would create another printer queue, this time selecting IP > HP Jetdirect-Socket. Then enter your IP address and select the K5400dn from the Print Using menu.
    If this still fails to print then please reply. There may be limitations with adding the HP driver this way that I am not aware of. There may also be other driver options you can look at, such as HPIJS. If Greg Sahli reads this posting he has expert knowledge on this matter and will be able to offer some guidance.

    I recently upgraded to Firefox 13.0.1 and I’m operating a Mac Powerbook Pro with OS of 10.6.8 (Snow Leopard).
    Now I’m having intermittent problems with sending emails where Firefox freezes up. There is often a yellow warning above suggesting 32-bit mode, sometimes I can click to shift it that way, sometimes not.
    Anyone having these problems?
    Any suggestions?

  • 've recently upgraded to FireFox v22.0. Originally, a legacy XBAP I use always opened correctly in FireFox and had no problems displaying or running. As of v22.

    I've recently upgraded to FireFox 22. Originally, a legacy XBAP I use always opened correctly in FireFox and had no problems displaying or running. As of 22, it won't even attempt to download the application, let alone try and display it.
    I have the windows Presentation Foundation 3.5.30729.1 installed, which is the same version I have been using in older versions.
    Can anyone shed some light on any changes that would have effected this?

    Hi, I have a similar problem. I did attempt the *.rdf fix on a test system, but it didn't work (em:maxVersion was already 22).
    We got about inflow of phone calls from our clients experiencing the problem mentioned above from the 2nd of July onwards... and more are phoning in.
    All the complaints come from clients (+- 10 so far and rising in number) using Firefox v22 (we have checked), and all of them have said that it was working previously.
    We downgraded one of the clients to an older version of Firefox, and it worked again. So far we are telling our clients to downgrade until a fix comes out, or use Internet Explorer (*blush*)

  • I had an iPhone 4 and recently upgraded to iphone5 now iCloud will not back up new phone.  Under iCloud it shows 2 iPhones and my iPad. Is it trying to write new phone over the old one?  What should I do?  I a, afraid I might lose everything messing with

    I see.  If you go to Settings>General>About>Name, that is the current name of your phone.  The backup bearing that name should be the more recent one, and therefore the one you want to keep.  I would delete the other one (presumably the one set up by Best Buy under your real name, assuming you changed it later), then see if that gives you enough space to back up again.
    If it still reporting insufficient storage, use this guide: http://support.apple.com/kb/HT4847 to try to determine what's taking up all your room.  In them meantime, you can perform a manual backup on your computer so your have a current one while you're troubleshooting this.  To do so, connect your phone to iTunes, then right-click on the name of your phone on the left side and select Back Up.

  • I interrupted the upgrading of muse and it will no longer open up. It's there but not complete.

    I hadn't used Muse in a while and opened Abobe Muse, it informed me that it need to be updated along with Adobe Air.  Somehow I interrupted the upgrade and it will no longer open as a program. I am not sure if I should uninstall the program and reinstall it?

    AFAIK you are on the wrong mailing list.

  • Firefox/3.6.10 shows message whenever I click on an icon needing Internet access, saying 'Firefox couldn't install this item because "install rdf" (provided by the item) is not well-formed or does not exist' and advising me to contact the author - ???

    Whenever access to the Internet is needed, clicking on any icon or link (including the Firefox icon) results in a delay of around 20 secs., followed by the appearance of the error message, headed "Malformed File". The message reads 'Firefox couldn't install this item because "install rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem.'
    Clicking OK or closing the box leads to a further delay of about 20 secs. after which the required action takes place! Of course, it could be said that it's really only a delay, so I should just get used to it, but it's still a malfunction, it's a pain in the neck or another region, and I really would like to cure it. Any suggestions - please????

    Tried that and it still isn't working. Not sure if it's software thing but I just noticed when I swipe up my control center the flashlight option is not available as well. I'm not sure why this is. I have a 5s with the newest software. That's for the suggestion

  • What's the proper protocol for a reset on my ipod touch 4g?  iOS 6 has totally jacked it up and it will no longer do anything but crash, and won't sync with itunes wirelessly or by cable.

    What's the proper protocol for a reset on my ipod touch 4g?  iOS 6 has totally jacked it up and it will no longer do anything but crash, and won't sync with itunes wirelessly or by cable.
    It's a 64G ipod touch and was fine till Apple told me to upgrade to ios 6.  Now most of my apps crash, my music won't play and I just get a white screen when I hit Music.
    When I try to sync to itunes it acts like it's going to sync and appears to recognize the ipod, but it's grayed out and has an update circle by it that spins for a while until itunes eventually freezes alltogether.  Is there a  way to go back to ios 5 after a erase and reset?

  • I dropped my 2009 MacBook Pro and it will no longer work; I need to re-install the OS software to hopefully restore it: what disk(s) do I use?

    I dropped my 2009 MacBook Pro and it will no longer work; I need to re-install the OS software to hopefully restore it: what OS disk(s) do I use?  This may sound like a stupid question but I'm seeking to buy something inexpensive and need to know if a higher version (other than what was initially installed) will work.

    Bekah1996,
    since you didn’t receive its original grey installation DVDs when you purchased it, you’ll need to contact Apple directly to purchase a replacement pair. (The grey installation discs aren’t available in the Apple stores.) Some Mid 2009 models originally came with 10.5.7 (Leopard), and some originally came with 10.6.0 or 10.6.2 (Snow Leopard). If yours had 10.5.7 installed, then you’ll probably receive a 10.5.7 set of grey discs from Apple. If you’d like to upgrade its OS to anything newer, then you’d also need to purchase the white retail Snow Leopard DVD — but you should wait to see what Apple sends you, since if they send you a 10.6.0 or 10.6.2 set, you wouldn’t need to purchase the white Snow Leopard disc.

    When I use find file http://www.macupdate.com/app/mac/30073/find-file (which does tend to find files that "Finder" can't), it's not coming up with any other itunes library files that have been modified in the past week, which I know it would have been - unfortunately, I don't have a very recent backup of the hard drive.  It would be a few months old so it wouldn't have the complete library on it....any ideas?  I'm wondering if restarting the computer might help but have been afraid to do so in case it would make it harder to recover anything...I was looking at this thread https://discussions.apple.com/thread/4211589?start=0&tstart=0 in the hopes that it might have a helpful suggestion but it's definitely a different scenario.

    I just bought a new laptop and my ipod nano will not stay connected to my computer. When I first connect the ipod it starts to sync on my ipod but not on itunes. The ipod is initially connected to my computer, I can see it when I look on devices in my computer. However, when it finishes syncing it is no longer detected to my computer. I cannot transfer any of my songs to my new laptop because of this. I have tried to reinstall itunes, reset my ipod and use a different port. None of these things worked. Any ideas?
