Firefox opens not at all on the macbook pro and then blocks mac entirely.

My firefox does not open when I clicked on the icon, there is a little blue light under it. I installed and re-installed and still does not. When I click the icon in the dock my macbook just hangs and I have to restart it manually. I'm afraid that my knowledge of this kind of thing is extremely limited, I read through many problems of messages but I do not understand the instructions others have given. It happened to my firefox and I renamed the file .exe (?) and that does the job, but I don't remember how I did it / can't find the post that helped me. I'm sorry to be so fundamental, but I can't remember and want my browser to work again!

You will not want Firefox to an .exe file, which is for windows. Make sure that the extension is. app. You can do this by going to Finder > Applications > Firefox > right click and click on the button "Get Info." Then halfway was the name of the file with the extension. Change it to Firefox.app if it is not already like this.

In addition, you can consult this article to support if it does not help.

Have a great day!

    Hello world

    just bought a new macbook pro 2015 and I can't transfer file via airdrop between the macbook pro and my iphone 6.

    Can someone please help me solve this problem?

    Thank you

    First check the steps to run the drop:

    There are some work around to try airdrop work:

    1. Turn off Bluetooth on your Mac.
    2. Delete /Library/Preferences/com.apple.Bluetooth.plist
    3. Re-turn on Bluetooth

  • Apple devices will not print not to 6700 Officejet, including the MacBook Pro and iPad

    I'm helping someone to implement their MacBook Pro and iPad to print wirelessly on their Officejet 6700. I have recently set them up with a new Apple Airport Extreme for their router. The printer connects to the wireless network. During the installation process of the printer is fine, that the MacBook can easily see the printer. The appropriate driver is installed. They also have a laptop Windows 7, which prints instanteously and has no problem whatsoever.

    When I try to print from the Mac, nothing prints. I open the print queue and it says 'Printing - a printer' and nothing ever comes of it. When you try to print from the iPad, you can see the printer and I select. However, after saying in print, said only dialog box: 'Connection to the printer' and he never - it just times out.

    Things I've tried:

    • Everything in this article which corresponds to Macs (10.8).
    • Reset the printing on Mac system.
    • Reset the printer to default settings.
    • The definition of the static IP address of the printer through the printer settings.
    • Setting the IP address of the printer via the Airport utility (after changing the automatic printer).
    • Restart the Mac after each attempt to remove the printer and adding again.
    • Using the official HP Officejet 6700 driver.
    • Use the Airprint driver.

    Other info:

    • Successfully, I can ping IP address of the printer from the MacBook Pro.
    • I can easily see the web page of configuration of the printer in the printer settings both by entering the IP address.
    • The printer is only about a month.
    • They bought this printer because the earlier had problems printing from all of their wireless devices. It is with a previous router in their ISP.

    At this point, I'm completely puzzled as to why the printer will print not these Apple devices. We have addressed all the issues that might be causing it: the network, the printer and the MacBook itself. I looked online and can't see any problem with people not being able to print to a wireless printer connected to an Airport Extreme. I saw some problems when the printer is connected via USB to an Airport Extreme, but this isn't our installation program.

    Any help would be greatly appreciated!

    Wow, I must admit, I had to do a lot of research to find something that you have not already tried! Thanks for your efforts so far @derick03 I accept the challenge of helping you get this to work.

    I have a vague feeling that the problem may have something to do with the router settings and to test my theory, I would like to try something for me.

    Please, open the preferences system, printing and scanning, click on the + symbol to add a printer, but this time, instead of the default tab, click the IP tab. Now let's add the printer using HP Jet Direct Protocol instead of the standard Hello.

    You can enter the IP address here, choose the HP Jet Direct and then select the printer driver, and then try to print. You will not be able to analyze this way, I just do this for diagnostic purposes. If you can print, it confirms the Hello Protocol is, and you will need to call Apple to make them turn on Hello, multicast and ensure that all the necessary ports are open.

    Not all wireless routers take load Hi or all features of Hello. Hello being the default method for the discovery of printers on a network, you must ensure that your wireless router supports Hello.

  • U3415 sharing the macbook pro and PC

    Hi all

    recently purchased the rather excellent U3415 and I'll put up my installation of small music at home.

    On my desk, I have my macbook pro and my pc. I want to be able to do is to use a keyboard and mouse for both systems. I can do this with the U3415? I am using a USB hub that is connected to the macbook pro (I have about 7 usb for music devices), but I was wondering if I could connect the USB keyboard and a mouse on the screen then somehow use just the mouse and the keyboard. I read the U3415 has a great feature KVM USB upstream and wasn't sure if it was the same thing. I know I can plug in Display HDMI port AND so move from pc/mac is easy for the side of the display of things.

    OK nm, received a schema, the all clear.

  • Firefox opens not at all, even after reboot and re-setup - IE opens normally - what can I do?

    I have used Firefox since version 3 - really like compared to others.

    This morning, after the startup of Firefox does not open. It worked when the PC was off last night. The eggtimer lights up briefly, then nothing. Internet Explorer works fine, just like Mailwasher (by e-mail) and MS Outlook, is not a problem of the internet.

    I am running XP Service Pack 3 (no, really, yet), with Secure Anywhere of Webroot internet security.

    I tried to restart - no effect
    I tried to remove, reboot, and reinstall - no effect
    I tried to run it from a link in an e-mail message - no effect
    I tried to run from the line start - run with the ~ option p as in your FAQ - no effect
    I tried to reinstall Adobe Flash Player, Shockwave, Java, etc...

    The closest, I have something to go is trying to launch a console of Webroot, when I got "Browser launch 1073741819 error" - but this could be an error code of Webroot.

    I don't know what else - make almost all your FAQ will be that you can enter the program.

    The only thing I can think is that webroot removed a threat this morning, but I can't find saved the crawl log for what it was - clutch at straws, maybe that had something to do with it?

    Maybe it's related, but I'll have to write this on another PC, because the Mozilla Web pages displayed incorrectly in Internet Explorer (all other sites I can find appear in normal type) so the plug-ins installed do not reflect what I have on the PC in question

    Yes. This means that another program has been in effect to prevent Firefox from running. If do not help the above suggestions, you can solve the problem, as described in the following article.

  • Firefox will not import all of the favorite Internet explore

    All my favorites Internet Explore will not transfer on Firefox. I already tried all of the suggestions:

    • import from internet explore
    • Export Favorites to internet explore then import into firefox

    Only half of my favorites are passed to firefox. Very frustrating.

    If there are problems with importing IE bookmarks in Firefox, then export favorites in Internet Explorer to a HTML file and import this file in the Firefox Bookmarks Manager.

    If you don't have the menu bar in Internet Explorer, and then right-click on the toolbar above to activate the menu bar.

    • Export Favorites in Internet Explorer to a file (bookmarks.html) HTML:
      File > import and export
    • Import HTML file in Firefox:
      Bookmarks > show all bookmarks > import and backup > import bookmarks HTML

  • iPad does not turn on/just the Apple logo and then turn off again

    I have an iPad, 4th generation, 64 GB with WiFi and cell phone, it is only 3 years and suddenly I can't turn on the iPad. When he started to act up it would freeze upwards with no icons or the button "home" in response, still on the screen, that he was freezing. I was able to restart it with the top button and it would work for 10-15 minutes and freeze no icons or the button being sensitive at home. I could do a hard reboot and when I rebooted, it would work again for 5-15 minutes and freeze once more. This was during a week and now it does not restart. When I try to turn on with the button at the top of the Apple logo appears, remains on the screen for about 3-5 minutes (no progress bar) and turns off again with no other screen appearing. I tried to find a solution online without success. Anyone have any suggestions for a fix for the iPad? I would appreciate any ideas that anyone could have.

    If the unit starts to turn back on the wide, then it seems that if you have a hardware problem. If the unit is charged and a reset will produce only a short period of service, then it is a hardware error or an error in battery, which would be also considered to be material. You can try to restore the device to factory and test without adding any additional content. If it still fails, then make an appointment at the Genius Bar watching him.
