Each time you start Firefox, I have error error [JavaScript Application]: is null. What is this error?

Each time you start Firefox, I received a message:

[JavaScript] error: is null

Maybe it's because I installed a few modules (including Greasemonkey scripts) or because of Java?
I disabled modules (most of the tem), but nothing helped.

Right, the problem has been one of the installed extensions.
Problem solved!

  • Each time you start firefox asked me if want to allow the program to make changes to the computer

    Whenever I start firefox, I wonder if I want to allow the program to make changes to my computer. Do not have this problem until I updated to the new version.

    This has happened

    Each time Firefox opened

    == I've updated to the new version

    Check that you are not Firefox running as administrator.

    Right click on the desktop Firefox shortcut and choose "Properties".

    In the Compatibility tab, make sure that this level of privilege: "Run this program as an administrator" is not selected.

    You should also check the firefox.exe program properties in the Firefox program directory.

  • Cookie permissions changed to allow each time you start Firefox

    OK, here's the deal. Recently, I noticed that cookies are allowed despite their has refused. After messing around, I discovered that everything in having disabled cookies, whenever I run the FF cookies automatically application becomes activated (both accept cookies & third 3rd party cookies is checked). I removed the Cookie Monster & it's the same thing. I already deleted the file prefs.js and this was not good. At the time, I toggle the installed Cookies, which I have to click every time FF launches. At the launch, it starts as denied, and then it turns into permits. Once I click the icon and set it on refuse, then the checkmarks in the boxes to get out. So why are cookies automatically set parameters to allow whenever I run the FF application?
    I wonder if DoNotTrack had something to do with it? I've removed from FF. I also Ghostery, but until a week ago, Ghostery & Cookie Monster played well together.
    Anyone have any ideas? The browser has been infected with something? Noted today, launch FF in safe mode shows also that the parameters of cookies change not to permit. Apparently something running in normal mode is at the origin of the problem. Other plug ins present on the browser are: NoScript, Foxy Proxy, AdBlock plus, fast Java and Norton toolbar.

    Have you tried to disable all add-ons that specifically mention cookies?

    If you feel that other settings changes do not stick, too , between sessions, this may indicate a problem with permissions or file locks in your profile folder.

    External your security suite or other security/privacy software have its own settings cookies could be pushing into Firefox in some way?

  • (Legitimate) -Pop-up Windows every time you start Firefox

    So, lately every time I start Firefox, the new browsing session retrieves the pop-up windows during previous sessions (since the last time or even some of love it, three days ago), I long closed down. My boot option was always "show my windows and tabs from last time ' who used to do exactly this: pick up the tabs I had open or start with a new blank tab if I had opened. Now, however, whenever I open FIrefox I get different windows of previous sessions.
    The problem here is that this doesn't SEEM to be a malware issue because I don't get weird ad/questionable windows but "legitimate" pop ups I me remember I started personally is to say a photo or an image of a trusted site that opened in a new window or a help section on amazon.com , etc.
    This is a first and as you can imagine it has become very annoying. I use Firefox 25.0.1.
    Any ideas? Thank you!

  • SE message file each time you start download

    The computer in question is used in a school setting and has been disconnected during the summer. It runs xp and IE 7. After hanging upwards, to every startup I get a message about an upgrade of the realtek driver, I think that not having is not enough memory to load, it will and then the dialog box "do you want to run or download this file", files downloaded from the internet can be harmful, etc.. The file is a Web site accessible from previos year, so I guess it may or may not be infected. everything I chose has no effect on it reappear the next time you start, reappears when ie 7 is open. It looks more boring than anything. These computers are used by children thus have a variety of glitches, crashes. any suggestions will be appreciated as maintenance is left to teachers for most

    I solved the problem by updating IE7 to IE8. I suppose that reinstall IE7 would have worked too. Seems somehting is stuck in the old browser. It turns out that it was even more embarrassing that I knew first, since the message will reappear when opening the browser or changing web sites. I had to install IE8 and reboot the computer before he went. If someone can explain why it worked, I would like to know

  • I receive the error message every time you start firefox: xmlNode.getElementsByTagName ("id") [0] .firstChild is null - 2

    Two weeks ago I started getting this error whenever I start up Firefox: xmlNode.getElementsByTagName ("id") [0] .firstChild is null - 2.

    I uninstalled and reinstalled Firefox, but the error persists. Then I did a restore and system several months ago, but the error persists. This does not happen with other programs.

    Does anyone know how to get rid of it. If it has nothing to do with the registry, I'll have to let it be and switch to another browser.

    Do you use Add-ons that create cookies "opt-out"? If so, check the cookies that you see at the beginning to see if they are the opt-out cookies. Or temporarily disable the add-on and restart Firefox to see if the cookies are still created.

    They are each a news Web site, so I want to "today's news" instead of the day before, when I checked the.

    If you reopen the pages automatically from the previous session then Firefox will load the pages in the cache and the above mentioned browser.cache.check_doc_frequency will not help in this case.

    You need to go to each tab and press the F5 key or click reload on the Navigation toolbar to get the page of the server.
