about: Config, Network.Http.Pipelining won't stay after it has been changed.

About: config, I changed network.http.pipelining false-> true. Then after restarting firefox, I'll go back to about: config and it came back to false. Any help would be appreciated. b

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

  • Do NOT click on the reset button on the startup window Mode without failure.

Your list of details of the system shows that you have a user.js file in the profile folder to initialize prefs each time you start Firefox.

The user.js file is present than if you or another software has created this file and normally it wouldn't be here.
You can check its contents with a text editor (right click: open with) If you do not create this file yourself.

The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

If you do not keep the changes after a reboot or have problems with preferences, see:

  • Pink sign above about the attachment e-mail saying dangerous attachment. It has been deleted.

    How can I cancel that my knowledge of the sender. This isn't spam.

    I had a similar problem, but the message I get is slightly different. It reads:
    Banned file type.
    This message contains an attachment whose file type is considered dangerous
    The file has been disabled.

    However, all disabled files file type is a regular .docx, IE the Word file. What more that these are files I received for a few months and receiving was not disabled. Also my security program didn't have a problem with them, either then or now. They seem to be turned off during the night, all together, almost certainly due to an update of Windows.

    I suggest that Ken verifies that the message he gets is not the same as mine before worrying about his contact its attachments are carrying a virus. Dare I say no matter what type of file can carry a virus but I do not see how a docx file can be considered a dangerous type itself. It seems more likely that there is a bug in the update of Windows.

    There is probably another person on another forum on this site with the same problem. They have been advised to sort through the Security Options in the file menu (it's in the Tools menu on my version).  Under the Security tab disabled option
    Do not allow the opening or saving attachments that could contain a virus.

    It worked for me, although I don't think it worked for the original questioner.

  • Somehow my search engine has been changed to yahoo from google, and now I can't get google search to stay as search engine, how can I solve this?

    I don't know how it happened, but can not get google search to stay as my search engine. I use the version the most recent Firefox is here. I deleted all the other search engines, but it always goes back to yahoo. Not like yahoo, I want my back lol, google. Please tell me how to solve this problem, thank you.

    Unwanted modules can take control of your settings in Firefox (search engine, home page, the new tab page) and make it impossible for you to fight them. Here's my method of tracking down and cleaning of the bad modules, the air pirates and injectors ad. I know it seems long, but it's not so bad.

    (1) open the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the undisclosed items bundle smoker who snuck out with some software, you have agreed to install. Beware of everything that you don't recognize / remember, since malware often uses sounding names important or innocent to discourage you remove. Out as much garbage as possible here.

    (2) open Firefox page modules using either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons
    • in the Windows "Run" dialog box, type or paste
      firefox.exe "about:addons"

    In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

    In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions. Do not forget that all extensions are optional, none come with Firefox, and you can learn more about them by checking their reviews on the site of the Add - ons.

    Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

    Any improvement?

    (3) you can search the rest of problems with scanning/cleaning tools listed in our technical support article: Troubleshooting Firefox problems caused by malware. These scanners on request are free and take a long time to run. If they end quickly, especially if they require the payment you have a serious infection. I suggest the specialty forums listed in the article in this case.

  • Question about Aperture library after it has been migrated to Photos

    After an Aperture library has been upsized to Photos, its extension becomes ".migratedaplibrary".

    Anyone know what effect, if any, has this change of extension on use Aperture?

    As far as I can see that the library can continue to be used as before, even if the changes do not appear in the library of Photos of course.

    I have a feeling that she could prevent this library will have to be transferred to the Photos again, but I guess that I might want to migrate again if I wanted to trash the original photo library and start again, or if I had added a large number of photos at the opening since the initial migration.

    Thank you

    I have a feeling that she could prevent this library will have to be transferred to the Photos again, but I guess that I might want to migrate again if I wanted to trash the original photo library and start again, or if I had added a large number of photos at the opening since the initial migration.

    It's true. The extension indicates that the library has been upsized. There is no other difference.

    Photos will not migrate the library with this extension.  I just change the extension back to .aplibrary after you migrate an Aperture library.  Then Photos can migrate again, if need be, and I can use it in opening again.

    BTW, the migrated Aperture library and new photo library share storage, but not the files of images, photos are stored very efficiently by hard links. See: Photos saves disk space to share images with your iPhoto or Aperture - Apple Support libraries

    and Six colors: the (hard) link between iPhoto and photo

  • Why Mozilla Firefox does not officially support 1.1 http pipelining yet?

    It's really more a technical philosophical question, but I thought I would mention it. While studying ways to improve my speed of navigation in general, I even found a ticket in Bugzilla 2004 debate this issue.

    While I understand that Mozilla wants to reduce the number of end-users of problems, enable this option in my browser increased considerably the speed by which loads major Web sites.

    As I ask, I want to assure you. I am currently using a web proxy and have "network.http.pipelining" and "network.http.proxy.pipelining" set to TRUE. What is the right way to activate this feature?

    Thanks in advance.

    I see the old bug to this https://bugzilla.mozilla.org/show_bug.cgi?id=264354 topic but it seems light may or should not cause problems, and browsers like chrome have problems loading page (see http://www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next, 3534 - 5.html) and they have it on by default. Note that there are not really of developers here. Just for the most part voluntary and or contributors.

  • New tab always opens Bing, but about: config does not have listed options...

    I have a question where my home page has been changed to the Bing home page, and after I corrected it seems now that any time I opened a new tab, it goes straight to the Bing...
    I found a solution to this in another thread, but it seems to be incorrect for my browser.

    type: newtab is the third option down that says searchinnewtabeenabledbyuser. Double-click on it and where it says 'true', ' false '.

    As indicated in the filename of the image as an attachment, there is no "searchinnewtabeenabledbyuser" on this page?
    So, I'm always curious about a correction for this problem!

    Don't know where you find this - searchinnewtabeenabledbyuser - pref pref invalid, does not exist by default. Could be added pref by an extension, for anyone who posted.

    Browser.newtab.URL is the pref you want - right click and select reset
    Then restart Firefox.
