The Firefox home screen "Different by design" keeps popping up even after disabling it in preferences.

<blockquote>Continued here: [[/questions/924123]]</blockquote>
I have installed the new Firefox on my Mac, OSX 10.6.8 by dragging the icon into Applications folder. I launch the app and the Firefox "Different by Design" screen pops up. My previous home page is in a tab behind that. I select "No" on the help improve Firefox question and close the window. Each time I launch Firefox or open a new window then the Firefox home screen returns. I checked the preferences and my company site is set as the home page. It does not matter if I uninstall Firefox, restart the computer and reinstall Firefox. I even tried installing older versions and the same error keeps happening.

Hi bigmex,
You should look at [https://support.mozilla.com/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox this article about that specific issue] and the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
If that doesn't work:
# Type about:config in the address bar
# Click ''I'll be careful, I promise'' if prompted
# In the Filter input field type ''startup''
# Double click on startup.homepage_override_url
# Delete the text string and click ''OK''
# Close Firefox and reopen the window to verify that it has worked.
Hopefully this helps!

  • The built in screen in my Macbook keeps blacking out, even though the computer is on.

    Hi
    The internal screen on my Macbook keeps blacking out; when this happens the computer is still on - just no screen. This happens when unplugged after a few seconds, and takes a bit longer when plugged in.
    If I close the lid and open it again the screen works again for a few seconds before the blackout returns. Obviously this is not the ideal work scenario!
    It does not appear that this is a backlight issue (I presume) as I cannot see any image on the screen when this happens from any angle.
    If I turn the brightness all the way down and then back up again the screen flicks on for a fraction of a second before anything happens again.
    Any ideas what might be causing this? If I can fix it? And/or how much an Apple repair of the problem is likely to cost.
    Many thanks for your help!

    Unfortunately it sounds like the logic board... happened on a MB I have at work. That's an Apple Store replacement, and can be expensive if your mac's out of warranty. Free if it's still covered...

  • Why does my Extras window keeps asking me to reload the Firefox window and not uploading my new plug ins even after I've reloaded it already?

    I have installed new versions of my plug ins and reloaded the Firefox page, but I noticed one of them wasn't working (the United States English Spellchecker 5.0.0) so I reinstalled it and rebooted the page once again. But it's not working and no matter how many times I reboot the page, it still asks me to do it. What can I do to solve this problem?
    This is the first time it has happened.

    This can happen if one of the files that stores details of installed extensions is corrupt. Try deleting those files as shown in the corrupt extension files section of the [[Unable to install add-ons#Corrupt extension files|unable to install add-ons]] article.

  • The Firefox.exe process hogs 25% of my CPU resources even after I've closed it.

    On a relatively consistent basis, when I close the Firefox windows I have open, the firefox.exe process doesn't end. When I go to open Firefox again later, I get the error message that I can't open Firefox because it's already running or not responding. When I look in Task Manager (on Windows 7 Home Premium 64-bit, BTW), the firefox.exe process is holding steady at 25% CPU usage along with whatever memory usage it already had consumed, even though the Tasks tab doesn't list Firefox as being open.
    == This happened ==
    A few times a week
    == I'm not exactly sure. It sort of just started on its own.

    Ed, this kind of issues are, unfortunately, more common and the we'd like. Thankfully, 99% of the cases are very easy to solve. However, you do need to diagnose what your exact problem is. Do this:
    #run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe-mode] to disable all extensions, themes and plugins. If this fixes your issues, be them with RAM or CPU usage, then you know it's a problem with plugins, themes or extensions. Proceed to number 2. If safe-mode doesn't fix the issues, then read bellow, after this list;
    #update all extensions, themes and plugins in your Firefox. If this doesn't solve the issues, proceed to the following number;
    #disable all extensions, themes and plugins in your Firefox (not running safe-mode). Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you WANT that plugin to be enabled, so keep your overall number of plugins as low as possible. When you encounter the problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all.
    #enable one extension at a time. Again, be certain that you WANT that extension to be enabled, so keep your overall number of extensions as low as possible. Also, try the theme you want to have installed so see if that is what's causing the problem. When you encounter the problems, you know you've found a problematic extension/theme, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all;
    #you're done! You've fixed your problems with problematic add-ons. If you want to keep using those problematic add-ons, please contant their author for support.
    Ok, if disabling all extensions and plugins through safe-mode didn't work to bring Firefox's CPU and RAM usage to good levels, then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Do as follows:
    #try reinstalling Firefox. No data will be lost. You can get the latest version for free at [http://www.getfirefox.com/ getfirefox.com]. If that doesn't fix the problem, proceed;
    #do a virus/malware check on your computer. If this doesn't fix it, proceed;
    #disable all software running in the background that you don't want to have running in the background (in windows, this is done by pressing WINDOWS+R in your keyboard, typing "msconfig" (without the commas) and pressing enter. Now, under the "Startup" tab, you can uncheck the software you don't want, and reboot your system for changes to take effect. If you're unsure of what software you want running, ask someone with more experience). If this doesn't fix your issues with Firefox, proceed;
    #check your firewall/antivirus/security suite for enabled functions/features that you don't want and/or may be conflicting with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable them to see whether or not that's true. As long as you don't browse the web with your antivirus completely off and your firewall completely turned off, there should be no problems. If this doesn't solve the issues, proceed to the following number;
    #check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem (after all, it's the last item on the list), it's remotely possible. If this doesn't work, proceed to the following point;
    #update your modem/router software. There have been some reports that some modem/router software may cause Firefox and other browsers to loose performance and/or stability. If updating doesn't fix your issue, try other versions of the software, if possible. If you need support with this, contact your modem/router manufacturer. If this doesn't help, proceed;
    #clean up your OS registry, using appropriate software. Make sure you've followed my instructions correctly, but if this all doesn't work, [http://support.mozilla.com/en-US/kb/Managing+profiles create a new Firefox profile] (this can be temporary, of course) and see if the issues persist.

  • My Mac Mini/Yosemite is new. But it now has malwares and Mac Keeper keeps popping up even after uninstalling.. Who can help?

    Hi everyone,
    My mac mini is new. I have a few issues with it.
    But the most annoying is the malwares that infested it now. I have only been using it for about 3 weeks or so. Of course, I thought everything that popped up are safe to click and just standard to click. I don't know yet what's best. Either, I figure out how to remove these ads / malwares or I just thought of reformatting it and start anew with it.
    What would you guys recommend and please include steps for me to follow. I'm no techy.
    By the way, I do not see these extensions on my Finder files (Conduit, also known as Trovi, MyBrand, or Search Protect, etc.) As a matter of fact, my extensions folder is empty except for the Adblock and AdBlock Plus that I recently installed to kill the ads.  However, it worked but it didn't stop MacKeeper and Facebook ads from popping to a new window each time I click a link, or just a space on a safari)
    On YouTube, when I watch a video, every second, the other videos are pushed down for as long as i watch, they are kept being pushed down. These are done by ads that are being stopped by the AB and ABP. yes, the ads do not appear. Just a white space forever adding up. Very frustrating. Please help.
    Thanks in advance!

    If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide, AdwareMedic, or Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support.
    Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
    The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
    Fix Some Browser Pop-ups That Take Over Safari.
    Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
    Quit Safari
    Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
    Relaunch Safari
    If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
    This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

    From user Joe Bailey comes this equally useful advice:
    The facts are:
    1. There is no anti-malware software that can detect 100% of the malware out there.
    2. There is no anti-malware that can detect everything targeting the Mac.
    3. The very best way to prevent the most attacks is for you as the user to be aware that
         the most successful malware attacks rely on very sophisticated social engineering
         techniques preying on human avarice, ****, and fear.
    4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
        your computer is intended to entice you to install their malware thinking it is a
        protection against malware.
    5. Some of the anti-malware products on the market are worse than the malware
        from which they purport to protect you.
    6. Be cautious where you go on the internet.
    7. Only download anything from sites you know are safe.
    8. Avoid links you receive in email, always be suspicious even if you get something
        you think is from a friend, but you were not expecting.
    9. If there is any question in your mind, then assume it is malware.

  • Why does the Firefox home page keep telling me I'm up to date when I'm not?

    The Firefox home page, found at http://www.mozilla.org/en-US/firefox/fx/ or by redirection from www.mozilla.com or www.firefox.com, tells me my version of Firefox is up to date. It isn't.
    I'm currently running 11.0 (and should have 12.0) but this has been happening for quite some time now; that page just seems to always say you're up to date, no matter what.

    It's a web site bug. It's been reported as #748741.

  • How do I delete bookmarks from the Firefox Home app on my iphone?

    I just installed Firefox Sync on my iphone and it has successfully synced all of my bookmarks. After I read a bookmark on my phone, I'd like to delete that bookmark permanently so I don't have to delete it on my computer as well. I can't find an option to delete bookmarks - am I missing something?

    No. It's very involved. That initial syncing of the bookmarks
    Was all done at once. After I processed the
    Firefox home app onto the phone. there has to be a way that automatically transfers any new bookmarks from the PC to
    The home app on the iPhone.
    it's supposed to sync automatically. but there is no new data.

  • How to change the search provider when using the Firefox Home Button Search feature?

    In Firefox itself I have configured duckduckgo as my default search provider.
    But when I use the Firefox Home Button Search it is always set to google and I do not see any option to change that?
    I like the Firefox Home Button Search (or whatever it's called) otherwise, but it's annoying that it does not use the default from Firefox.
    I use the Google Now Launcher.

  • I hate that with ios 7 my bookmarks show up on the safari home screen. Is there a way to remove the icons from the screen without deleting my bookmarks completely?

    I have recently updated to ios 7. On my safari home screen there are my favorites listed. I absolutely hate it. Is there anyway to remove the bookmarks from the safari home screen without deleting my bookmarks completely? I am resisting the urge to throw the whole **** thing away and buy another tablet. Please help me! I usually love the updates but I feel ios 7 is more than I can bare. If I wanted Window's crappy format I would have bought a Microsoft product!

    On your safaris home screen is a square icons consisting of your favorites and the IOS 7 favorites ( Disney,Apple,Yahoo,Etc) and I knew I wouldn't use these so I wanted to learn how to delete them. So, after messing around a few times with them, I realized how easy it was to delete them. All you have to do is go to the top right corner of your homepage and click on the book icon (found left of the cloud icon). Once you click on it, your history for safaris searches should come up. On the top left corner above your history should be " <Bookmarks " written in blue. Click on that and a list consisting of these should come up ( top to bottom of list ) FAVORITES / HISTORY / GOOGLE /BING / IPAD USER GUIDE. Click on FAVORITES. Your list on the favorites on your home screen should come up. Simply slide over the item to your left (EX.. Yahoo) and a DELETE button in red should come up. Click delete and your done, the icons should disappear on your home screen. Only bad is that you have to delete them from your favorites too.

    I don't know how you received an upgrade for iTunes.  You make it sound like it was sent to you.  At most your computer will tell you of a new version and you tell it to download it and install it.  However, a computer will not do this for a version which is incompatible.  iTunes 10.7 came out a few weeks ago but your computer would not notify you and even if it did, 10.7 would refuse to install on your computer.  So this part isn't making a lot of sense.
    Two ways to get the 'newer version' message.  One is to open your library on a computer running a newer version, and then try to open it with an older version.  Usually happens when the library is on an external and used with multiple computers.  The second way is if you have multiple versions of itunes installed on your computer.
    The newest (and likely the last) iTunes for OSX 10.5.8 is iTunes 10.6.3 which has been out for quite a while.

  • Folders & apps are locked when moved onto the 2nd home screen

    Hi,
    I'm hoping someone can help me. My little boy has a Playbook and he's moved a folder full of games from his home screen onto the 2nd home screen (when you swipe it across to the left).
    When the folder has moved over it's now locked. We can't open it or move it back onto the 1st home screen.
    I opened his Facebook on his first home screen and it opened fine but I've tested it and swiped that also onto his 2nd home page and that app is now locked and won't open or move.
    Could someone please let me know why it's doing this and if I can move them back across??
    Thanks in advance

  • Is there any way under iOS7 to show the full home screen without the 3D band at the bottom reducing picture size?

    Is there any way under iOS7 to show the full home screen without the 3D band at the bottom reducing picture size? I want to see full pictures from my camera roll, not "special effects" from Apple..

    By 3D band are you referring to the Dock area where apps like Safari and Mail live? If so there is no way to remove this.

  • Ipad icons shaking, NOT the customize home screen!

    I've had an ipad now for about 2-3 months.  While using it regardless of the app, the icons start moving randomly moving side to side and the search screen will show up along with the keyboard.  This is NOT the customize home screen shaking that have a black x to remove apps, etc.  This was happening before and after iOS6 upgrade so it has nothing to do with the OS upgrade, it seems to be a hardware issue.
    Below is the link to a video I took:
    http://youtu.be/kIGLJrTvxLw
    Any ideas?

    Try a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. The screen will go blank and then power ON again in the normal way.] It is app and data safe!
