Firefox Forum di supporto

Java Script Application Type Error components classes (cid) is undefined. I have a mac book running version OS X 10.5.8. I recently installed the latest version of firefox on my laptop and now getting this error everytime opening firefox.

I have several Add-Ons that state "This add-on will be installed (uninstalled in some cases) when Firefox is restarted." No matter how many times I restart Firefox they do not install or uninstall.

Some of the Add-ons include Adobe DLM (which is a major pain in the ars to begin with), NoScript, and United States English Spellchecker. I have had problems with other Add-ons not installing after after an update but after several attempts to reinstall them from the Add-on Gallery the finally installed again.

I have been trying to install the recorder on ksolo. I was told I needed to use the add-on from firefox. However, when I tried to use the add-on it said it wasn't compatible with the current updated version of firefox.

I am new to Firefox. I just switched to IE8, and I'm not used to that much junk at the top of the screen. Maybe this is in the wrong category, but again, I am new to Firefox. Help!

When browsing the add-ons offered on mozilla.com many say "not compatible with Firefox 3.0.2" and will not let me install even though when checking the version using the "About Mozilla Firefox" in the Help menu it says I have 3.6.8; How do I get the add-ons page to recognize that I have a newer version of FF?

i also wanted to check an activity calender from a website and it says : "The Adobe Acrobat/Reader that is running can not be used to view PDF files in the Web Browser Please exit Adobe Acrobat/Reader and exit your Web Browser and try again"> of course nothing works so can you help please?

I have just upgrade to the latest version of Firefox as recommended to fix security issues. Now, unfortunately, I can no longer access any of my add-on. A few of which are very important to me as I use them extensively.

I am trying to install the print module for ticket printing in my company's ticketing web site. In IE8 under internet options there is a trusted sites section of the internet options tab

I'm running 3.6.12 and as recently as yesterday the majority of my addons are not working/showing up where they would normally be. I've tried deleting the 3 extensions files in the profile to reset the cache, but this hasn't helped. FF is also exhibiting other strange symptoms. For instance, if I click "help" and "troubleshooting information" it just opens up a blank tab. If I click a link outside of firefox it opens up a blank tab. I haven't made any recent changes to firefox. What can I do?

I'm running Win7 Home Premium 32bit

I'm working on a Corporate installation of Firefox and I need an add on to be available for all users who loginto certain workstations. The add on is the ProCon Latte, that does Whitelisting.

I speak English. I am living in Chile and have a Dell/MS Windows Vista (English) laptop. I have Firefox 3.6.12. I have installed the Spanish (Mexico) dictionary. I right-click in a Yahoo e-mail window and select Languages - Spanish (Mexico) and start typing in Spanish, but it is not correcting my mistakes, or offering alternative spellings.

I don't know if I have the correct plug-in, correct settings, or am expecting something that isn't possible.

I read and followed all the instructions for uninstalling blocked add-ons. Safe mode didn't enable the Uninstall buttons and the folders for blocked add-ons don't exist in either the profile or installation extensions folders. They still show up as installed. Now what?

My computer has Windows XP, I also have Mozilla Firefox. I don't understand why sometimes, a bar appears across the screen, where the tabs should be , and it says I need to install plug ins. It has a button that says, install, and one that says, click here to find out what plug ins you need. I've tried pressing both of them on different occasions but no luck. Can someone Please Help me??

I cannot seem to find or install a plug in for reading pdfs in the browser window. I get that yellow bar telling me I need a plug in and click to install but nothing happens or changes
