• Console developers saying function is "undefined", but the feature works well

  I'm a web developer, and I worked on creating a site ( http://mythicalslab.x10host.com/ ). On the site, I have little javascript that handles display a div with a top loading animation. In the html script tags, I have two defined function, hideLoading(), and showLoading() who respectively show and hide the loading animation.

  If I go in the Javascript console in Firefox and type hideLoading() or showLoading(), the console says "undefined", but it still works function.

  If you want to verify this put for yourself, go to my homepage ( http://mythicalslab.x10host.com/ ) and showLoading() to type in the console dev and you will see it will execute the function and display the loading animation, while saying that it is not defined.

  Undefined is on the return value of a function call.
  You will see something useful that a function returns the value.
  If nothing is returned, so you see not defined.

• How to remove the extension add-on "undefined"?

  I have an add-on called 'indefinite' who has 5 buttons: enable, disable, Options, delete, ask to activate. I want to remove, so I clicked on the button Delete, then he said "Nation Toolbar has been removed"... but after I go back to my list of Extensions, it's still there... I already tried to remove in safe mode, what has not worked... It seems that this situation has begun to uninstall the toolbar annoying Nation who hijacked my browsers... Please help me solve this problem...
  In addition, please do not suggest to reset firefox...
  BTW, the 'indefinite' extension does not appear in the troubleshooting information...

  I fixed it! I was wrong to do not find anything in the profiles... I found a folder inside the extensions which is called as {ADFA33FD-16F5-4355-8504-DF4D664CFE09}... and found that it is what is causing the extension "undefined"... Then I deleted it, and solves the problem... Thank you all for your support!

• 22 Firefox displays an undefined repeatedly. Also freezes at startup

  Since Firefox updated to 22, I asked problems with Firefox. It worked completely fine until now.
  There are two issues I have here.
  1 Firefox crashes when I open it. Has a small chance to hang does not sometimes, but the browser would be too slow to use.
  2. this problem happens when I go to any site. When I load a page, the undefined Word is shown repeatedly through the entire page.

  I tried to disable the following addons, but two problems:
  Internet Download Manager, Stylish, NoScript, dictionary, quick search

  I get crashes when you open the browser, so it is difficult to test the other addons. What is strange, is that these addons work very well on the desktop of my brother.
  My other addons not tested: Speedfox, WOT, Adblock, FVD fast dial, quicknote

  I'm running out of ideas to fix. There are other methods for fixing of my browser? I am able to get a list of diagnostic of my browser, I can post here for assistance?

  Are you aware that Firefox 22 is in beta test and that he will not be released for nearly 5 weeks?
  
  21 of Firefox is the current version.

• I use AOL for email and Firefox 9.0.1. Problem started 2 days ago. Before that I put in the two first letters of an email address and he gave me a list of possible. Now I get "undefined" for each possible instead of the email address.

  There is no problem after updating to Firefox 9.0.1. My contact list always displays as he did before that this problem occurred. When I type the first letter or two of the email address, it used to give me a list of possible. Now t shows just as "undefined" e-mail address when he gives me suggestions for the address that I type in the invoice line. This means that instead of being able to click on my choice in the possible he gives me, I have to go to my contact list, find the name and then click on it if I send email to a person. If it passes in more ways than one, I either enter the full address or use copy and paste from the list of contacts. It is a huge hassle. Any help is appreciated.

  You use like CCleaner cleaning software?

  It is possible that there is a problem with the file that stores the data for the "saved form.
  
  Rename or delete the formhistory.sqlite (more formhistory.sqlite - log and formhistory.sqlite.corrupt, if they exist) in the profile folder of Firefox in the case where there is a problem with the file that stores the data for the "saved form.
  
  Which will remove all the data forms, so you can rename formhistory.sqlite to formhistory.sqlite.sav or move the file to another folder in case you need to retrieve recorded data.
  
  If that worked, then you can delete the files renamed.
