Firefox ActiveX error

Answer 1

While Firefox does not natively support ActiveX, you probably have a plug-in to enable ActiveX in Firefox, most often in support of sites that wish to embed content in Windows Media Player in the browser. Find a page where you are likely to see the error. My experience is that Amazon.com and even Wiki.Answers.com will work, but any site you know to cause the error is fine. Acknowledge all the error popups. On the menu, go to Tools, Add-ons, and select the Plugins section. Look for any entries that mention ActiveX. Common plugins are "Mozilla ActiveX control and plugin support", "Yahoo! activeX Plug-in Bridge", or the "Windows Media Player Firefox Plugin". Disable ONLY ONE of the plugins at a time. The change is immediate and should not require a browser restart. You can leave the Add-ons window open until you complete the testing cycles. After you disable a plugin go back to the browser window and use F5 or Control-R to reload the page. If you still get the ActiveX Error then that plugin was not the culprit. If you have not found the plugin then re-enable the last plugin you disabled and then disable the next ActiveX-related plugin. Test the website in the browser again. When you find the plugin that stops the error then leave that plugin disabled. If disabling plugins one at a time does not stop the error then disable all the ActiveX-related plugins and test again. It is possible you have two offending plugins. The reverse test in this case is to enable one plugin at a time to see which ones yield the error. When you are done with the Add-ons window simply click the X to close the window. It is possible to remove the offending plugin altogether by removing the plugin file itself. You have to know which file to remove, but it you are uncomfortable with working with files then simply leave the plugin disabled. It will not cause any troubles unless something ends up looking for that specific plugin (highly unlikely). The plugins are usually in "C:\Program Files\Mozilla Firefox\plugins". For each file you can float your mouse over the filename without clicking the file and you should see a little popup box that starts with "Description", which should exactly match the plugin name listed in the Add-ons/Plugins window. One your find the offending file simply delete the file. When properly deleted it will end up in your Recycle Bin. You can, if needed, later restore the file from the Recycle Bin, at least until you empty your Recycle Bin. If you do need to support Windows Media Player embedded in your Firefox browser then look for the "Windows Media Player Firefox Plugin" at http://port25.technet.com/pages/windows-media-player-firefox-plugin-download.aspx. This plugin should be safe in post-2.x Firefox versions (at least as of this writing on 28 Nov 2008).

This post is correct I found the offending plugin to be something called the "Mozilla ActiveX control and plugin support" I just disabled that in it is now fine. There is a user in the discussion saying this post is rubbish but I'm afraid that is not true

Good luck!
