ok trying to start a new question. Hope I am in the right place... I was able to download and install an older version - Moz FF 26; however, with practically each keystroke I get these 2 error msgs: " [JavaScript Application] ! initXPCOM TypeError: compClass is underfined" AND ""onLoad TypeError: can't access dead object" It keeps happening - so much so that I will go back to Google Chrome until I find a fix. To recap, I had a real problem with what I thot was a msg from Mozilla to update; I finally uninstalled my Moz browser; then I ran into several warnings and error msgs, then I gave up for awhile. I was avoiding various links that were not direct from Mozilla; then I went to Mozilla support; I was warned NOT to install an older version, but nothing was working, so I tried that and was able to download & install Mozilla 26. Yet I keep getting that [JavaScript] error ?????

I tried several links offered in the forum.

Moses: Unable to download a current version of Mozilla - 28 now ? Installed older version Moz 26 - keep getting this JavaScript error. Too much to deal with - so I am using Google Chrome until I can get the latest version of Mozilla to download and install. again, I get a warning with each try, using both IE & GC. I also was getting some help from "bermea" but last msg said to go to < http://www.mozilla.org > and download/install a "clean" version of Mozilla - no can do ! ! ! but thanks for trying

Please check for a rogue extension. I recommend you disable ALL nonessential or unrecognized extensions on the Add-ons page. Either:

  • Ctrl+Shift+a
  • orange Firefox button (or Tools menu) > Add-ons

In the left column, click Extensions. Then, if in doubt, disable.

Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Does that help?

Note: If there are extensions that do not have a Remove button, typically the uninstaller will be in the Windows Control Panel, Uninstall a Program. If you click the "Installed on" column heading the most recent additions should come to the top where you can identify what kinds of bundled baddies might have snuck on board along with something you actually wanted.

Okay, I eventually figured out where your earlier thread was. Yes, several of the extensions look sketchy: https://support.mozilla.org/questions/995035#answer-557644

By the way, there is an updated version of the Yahoo toolbar: http://us.toolbar.yahoo.com/
