Why won't Firefox install after downloading?

After numerous attempts to fix an installation of Firefox that hung every time I opened it, I uninstalled it. Now I cannot install from the download after following the instructions.

Firefox 4 versions and later do not run on a PowerPC Mac.<br />
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

  • Why won't Firefox install after I've downloaded the latest version? I can't get it to open. I have it on Mac with OSX system. It worked before the storm killed the power but now it won't open up at all, using the same methods I used before.

    My power was shut off due to a storm. When I fired up my Mac, the Fox was nowhere to be found.

  • Why won't Firefox 29 open downloads?

    Ever since that blasted Heartbleed came on the scene, Firefox 29 has been driving me baka nuts! First it blocks legitimate websites. Now it won't let me install downloads of software and programs! It won't even let me open programs in my Start Bar or Task Bar! That includes Windows Update! Now I just tried to install RealPlayer/RP Cloud and it won't install! No idea what is safe to remove when Malwarebytes finds it. MS Security Essentials and Glary Utes 5 both come up clean. If Maxthon 4 worked I'd ditch Firefox but only Firefox will most of my survey groups allow as a browser! How about some help? Email me direct if you prefer at [email protected] or at [email protected] Thanks I hope- keimanzero

    Firefox should not block programs outside of itself. Also, I don't think there were any changes in how Firefox works due to Heartbleed.
    It has a line at top that says Firefox did not allow the program to open. I hit Allow and sometimes it disapears but usually it keeps coming back up.
    Let's start with websites being blocked. What does that look like? Do you get an SSL certificate error page? Or do you get the mixed content block (shield icon) on the address bar? Or do you get the warning that the site is involved in phishing/malware? The more specific you can be about this, the better, since it may be an add-on or external filter feature that we need to track down.
    None of the above.
    When you download an executable (installer), are you trying to launch it from Firefox's download list?
    Yes.
    Does it work any better to click the folder icon on the right side of the item to "Open Containing Folder" and launch it from there?
    That won't work either.
    Windows update needs to run through IE, either in the browser itself, or using the Control Panel widget. Firefox does not support the ActiveX controls used by the update site to scan the registry for previously installed update.
    I am trying to find the page that tells me which IE I have and whether it's working or not but the page won't open.
    For malware cleaning advice, there are a couple of dedicated forums listed in our support article: Troubleshoot Firefox issues caused by malware. Those will be much more familiar with the safe use of the tools than we are here.
    How do I know exactly what those detected objects are that Malwarebytes claims are dangerous? How do I know which registry entries are OK to delete/quarantine?
    Thanks for the help guys.

  • Why won't Firefox open after updating? Says to close, but how?

    Windows 7. Attempted to update to latest Firefox today, but it won't open on my screen. When I attempt to either use the previous version or delete it, it says to close it first. How do I close something I can't see? Thanks.

    See:
    *http://kb.mozillazine.org/Browser_will_not_start_up
    Try to run the Firefox program once as Administrator (right-click firefox.exe: Run as Administrator).<br />
    If that doesn't solve the problem then remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) to do a clean reinstall.
    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • I had original iPhoto app from 2007, but in the last year it stopped working seemingly out of nowhere.  Now I just installed iPhoto 9.5.1 but it won't open even after downloading the iPhoto Library Updater.  My pictures are lost in the abyss.

    I'm using OS Extended 10.9.5.  I don't know what the original version of iPhoto was.

    Have you run the iPhoto Library Upgrader? You need to direct it to the location of your old iPhoto Library by clicking the "Choose Library" button in the lower right corner of the panel you are seeing when the upgrade starts.

  • Flash won't install after downloading...early 2013 MBP/Retina, 8GB DDR3 1600 MHz Ram, 3GHz Intel Core i7 Processor (clean installation)

    Flash Player won’t install after downloading
    On the first attempt to install v14, Flash Player v13 was installed and working fine.
    I opened the installation package for the new Flash Player, followed standard protocol for installing Mac software and it hung before retrieving anything.
    Subsequently, while watching the beach ball spin, I got an error message that the installer could not retrieve the v13 Flash Player software.
    So I uninstalled Flash Player 13 and again attempted to install v14, only to see the spinning beach ball followed by a message that the installer could not retrieve the v14 Flash Player software.
    I am running OS X v10.9.4 on an early 2013 MBP/Retina display with 3GHz Intel Core i7 processor and 8GB DDR3 1600 MHz Ram.
    If you have any ideas or suggestions regarding my issue, please let me know.
    Sincerely.

    Try un-installing and then re-installing via the web site.

  • Why won't Firefox won't download?

    Why won't Firefox download? It completed the set up stage then stops.

    If downloads hang at the last minute (just before reaching 100%), the cause might be antivirus software which tries to scan the file and during that process hangs the Firefox instance.
    In order to fix the problem, try disabling the scanning as follows:
    # In the [[Location bar autocomplete|Location bar]], type '''about:config''' and press '''Enter'''. The about:config "''This might void your warranty!''" warning page may appear.
    # Click '''I'll be careful, I promise!''', to continue to the about:config page. A list of settings should appear
    # Filter the list by typing in the search bar at the top. Type in ''scanWhenDone''. '''You should now find the "browser.download.scanWhenDone" preference'''.
    #Double-click on that preference to set the value to ''false''.
    #Next, try to download something and see if it still hangs.
    Please reply and tell us whether this helped you!

  • Why won't firefox search?

    Why won't firefox search when I type anything into the search bar? It lists everything I've typed in before but when you click search it just sits there doing nothing. If I use the search bar in the top right corner it searches just fine, but nothing from the central search line.
    Also what is the line below this for? if I mouse over it I get a pointy finger, but it is blank and remains blank.

    If you can't clear that saved form and search history then there may be nothing to clear.
    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • Why won't Firefox automatically show new Hotmail emails or easilly down load attachments when it was working a week ago?

    Why won't Firefox automatically show new Hotmail emails or easily down load attachments when it was working a week ago?

    Hotmail has been having a few hiccups lately I'm afraid.
    If you don't see any emails when you log in, or nothing appears after some time, click in the middle of the grey bar on the left which has the word "'''Inbox'''" in it. This usually causes them to magically appear for some strange reason.
    I've read on on a few blogs that Microsoft is working on the problem, but don't hold your breath.<br><br>
    If this suggestion resolves the problem for you, please click the '''Solved it''' button next to this post after you log in into the forum. This will help others searching for a solution to the same problem.

  • HT1657 Why won't the bought and downloaded films play?

    Why won't the bought and downloaded films play?

    It won't let me download iOS 7.  When I check for software updates it says that it is up to date.  I also went to iTunes to delete the songs from the iPod, but now it isn't even recognizing any devices.  I even uninstalled iTunes and reinstalled it to my computer.  LOL  I am sure it is something small, but I don't have the patience for it now.  Maybe I should step away from the computer and come back in a little bit...    Thank you for the advice though!  Keep it coming!  I know it is hard to diagnose over the internet, but any ideas help!
