Hello Kelli.

Active X is a proprietary non-standard technology and is only used by Microsoft.

how about english...

Did you read the link provided? https://support.mozilla.com/en-US/kb/Active+X

For pages designed for IE only, you can try this add-on: https://addons.mozilla.org/en-US/firefox/addon/10909/

The article that I liked to is in English. If you don't understand it, I can break it down for you.

"ActiveX" is a technology owned by Microsoft. "ActiveX" is in Windows only (not Macintosh, Linux or any other system), to add functionality to applications.

"ActiveX" is often used in Internet Explorer (Microsoft's web browser) to view and use multimedia content in web pages. "ActiveX" is also used by Internet Explorer itself for things that are not related to webpages, but rather to the browser (for example, the browser's interface).

Firefox does not support "ActiveX" because:

• "ActiveX" is just available on Windows, so pages that use "ActiveX" will not work on Linux or Macintosh, which are both supported by Firefox.
• "ActiveX" is bad in terms of security, and applications that use "ActiveX" are susceptible to get your computer infected with virus or malicious software.

Firefox uses plugins to view and use multimedia content in web pages, and extensions to add new functions. You can view extensions and plugins by going into Tools > Add-ons.

If you visit a website that uses "ActiveX", report the website to Mozilla, by going into Help > Report Broken Web Site... and filling out the "Report A Broken Web Site" form and click Submit Report.

I hope this helps.

can't run active x

Exactly. ActiveX is not available in browsers other than Internet Explorer.

I have just removed adobe active x control from control panel, I access yellow pages for info and got a pop up message which said "we would like to store information on your computer". There were two boxes below which gave me the option of permitting access or denying access I click on deny. another box popped up and I was unable to close the box. The only way to get out was to close the "yellow page 411" page. so I then went to control and removed active x 10 I hope I've done the right thing

@dggs

You probably removed Adobe Flash ActiveX, which deleted the Shockwave Flash program which is used by Internet Explorer. That's fine as long as you don't use IE any longer.

"we would like to store information on your computer" is something entirely different. That pertains to the storage of specific data to allow you to work offline without an internet connection. It is a fairly new concept that not many websites have even started to use. I attempted to find an explanation aimed at internet users ("customer's perspective"), but all I could find is technical information aimed at program developers and website developers.
