After update FireFox to latest version 22.0, once I turn on firebug, all the opening firefox browswer will hang and respond slowly. Please help.

Previously Firebug is working perfectly with FireFox and it helps a lot on web development.
But few times of FireFox updates, once turn on the FireBug, FireFox will always hang, slow response, for example, clicking one button or one URL link on web page, it will take around 3 seconds only response. Click the scroll bar to scroll the page, the page will only scrolled after few seconds. The loading image on the tab will also hang and not circling.
Once turn off the Firebug, everything working fine.
It will be FireFox update having problems or the FireBug not compatible with the updated version of FireFox?
Try to search the updates for FireBug but it's the latest version.
Try to disable all the add-ons, plug-ins, not solving issue.

Hello,
Go to about:config and try turning off javascript.options.strict .
Firebug is known to be very intense on Ram, try turning it off when you don't need to use it.
Hope this helps!

  • A div in a site am developing is not showing in firefox but shows on all the other browsers (chrome, safari, opera and explorer), can anyone help?

    i am developing a site and i used divs in making the arrangements.
    all other divs on the page shows but on particular one does not show.
    i gave all the divs a border with a red color, all the other browsers(explorer, opera, chrome and safari ) shows the divs with the colors but firefox does not even show the red color

    Can you post a test case demonstrating the problem? It doesn't need to contain confidential content or active links. (This forum doesn't handle raw HTML very well, so I don't recommend pasting code here unless you convert your angle brackets to HTML entities.)

  • Sine the most recent update, firefox "not responding" is happening all the time. What is going on ... please help!!!

    Firefox had been "not responding" for the last few months. After a short time, it would respond.
    Lately, however, it is "not responding" and my entire computer needs to be restarted.
    Please help -- I am extremely frustrated.

    Perform the suggestions mentioned in the following articles:
    * [[Firefox is already running but is not responding]]
    Check and tell if its working.
    May not be related to your problem but some of your Firefox Plugins are out-dated
    * Update All your Firefox Plugins -> [https://www.mozilla.org/en-US/plugincheck/]

  • HT1925 I downloaded the latest version of Itunes last night.  I uninstalled all the apple products in order but the new version won't load.  I keep getting a runtime error R6034 ProgramC:\Program files\Itunes/itunes.exe made attempt to load C runtime libr

    Can't get the latest vesion of Itunes to download correctly.  I keep getting a runtime error R6034.  I tried uninstalling all the apple components in the order given. anyone having any good advice to solve my problem?

    Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
    Remove all of these items in the following order:
    iTunes
    Apple Software Update
    Apple Mobile Device Support (if this won't uninstall move on to the next item)
    Bonjour
    Apple Application Support
    Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
    The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.

  • HT1947 After updating My Apple TV to 5.1 I can browse music library using the Remote app on my iPhone and iPad but cannot select a song to play. Is someone else having the same problem?

    I have updated my Apple TV to 5.1. Using the Remote app on my IPhone and iPad I can browse the music library on the Apple TV but I cannot select a song to play. Has someone else the same problem?
    Mats

    I think I found the reason. On my iMac that is hosting the music library a song already was playing. This seems to block out me from selecting another song though my Apple TV.

  • I cannot get Firefox to come up. It says it is running but cannot find it. I have uninstalled and reinstalled. Please help.

    When I try to bring Firefox up it does not show that it is. If I shut my computer down it will come up the first time and as long as I leave it open it is okay. When I log out it does not come back up the next time. I am not having trouble with Chrome or Explorer.

    The Firefox Home app for iOS is not the Firefox browser but rather for to synce with your desktop Firefox to have your Firefox desktop history, bookmarks and open tabs on your iPhone/iPad.

    We have no plans to release the full Firefox browser for iOS. The iOS SDK agreement requires apps to use Apple's own JavaScript engine (or none at all, like Opera Mini which downloads pre-rendered pages from Opera's servers and cannot run JavaScript code in the client). Because of this, we have no supported way to distribute Firefox's rendering and JavaScript engine to iPhone users.

  • After upgrading to iOS5 all the pictures in my camera roll are gone. Please help.

    I synced my phone through itunes prior to upgrading to iOS5. Then the upgrade also backed up the phone. Upon the upgrade completing I was browsing through my phone and noticed that all the photos that were in my camera roll are nowhere to be found. Can anyone help me?

    I have the same problem. I bought an iPod Touch 4G 64GB last June. After upgrading to the new iOS 5, most of my pictures, apps and music is gone. Every time I try and recover my backup the system crashes. I tried to call their technical support to restolve the problem but I was told that I had to pay $29 to solve the problem that they created. This is a disgrace.
    People are saying restore the iPod but with mine that didn't help.

  • After updating iTunes to latest version, Firefox will not load.

    I installed the new version of iTunes that supports ios6 this morning. Right after that Firefox will not start. It flashes some kind of message in the lower right corner that I cannot read. Task Manager says it is running, but not on my screen.

    Look in Processes in the Task Manager. If Firefox is running, you see firefox.exe in there. You can remove it from there.

  • Running latest version of Mozilla. After updating Flash to latest version it will not work. Pages indicate I need newer version. Any ideas?

    Flash version. 11.3.300.257
    Mozilla version 13.0
    Windows 7
    Flash works on Chrome and IE.

    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    *Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
    Try to disable hardware acceleration.
    *Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

  • After update itunes to latest version I can't open itunes pages

    I update Itunes to 10.5 and now I can't open pages .
    If I uninstall and install old version everything is OK.
    This situations is for 2 computers ( win 7 and win xp )

    Hi
    It happens to all pages where a Flash element has the size of 100% width / 100% height of the window or frame. Flash elements with fixed pixel size do not cause a problem.
    I think it's not a Javascript problem, because it also blocks the window resize if you just call a swf file with no html around.
