Firefox 4 and pdf viiewers

Since upgrading to FireFox 4, I find that the Tracker PDV Viewer frequently crashed.

Ignoring Adobe Reader, are there ant alternative pdf readers that work well with FireFox? I am thinking of ones that use plug ins - so that the document opens within the browser window itself?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is this a Windows system?

1. Probably corrupt install. Uninstall Firefox 4 then uninstall previous version. Then do clean install of Firefox 4 and install the plugin.
2. Firefox support page notes many plugins not working and solution was to uninstall FF4.
3. "In Firefox 3.6.4 and above, some plugins are loaded separately from Firefox in plugin-container.exe, allowing the main Firefox process (firefox.exe) to stay open if a plugin crashes. For more information, see Plugin crash reports."
