I have an web based app that is specific to my company. When I run analysis I have to Switch rendering Engines to get it to display properly. Before I did the update today I used to right click on the tab and choose "Switch Rendering Engines" and then run it. But now that option is no longer there when you right click. I have hunted all over everywhere to find it but can't, Please let me know ASAP how to access that feature. Have to be able to run that to make it work.

Thank you, Amy

Firefox has never had a "Switch Rendering Engines" feature. Maybe you had an extension which added that feature to Firefox and now that extension is disabled or isn't working? Just a guess as I have never seen an extension for Firefox such as that.

Were you using an extension like IE Tab or IE View?

Yes, I used the IE tab - version 3.6 solved my problem. Added switch rendering engine and made the app work like I needed it to.
