Unable to enlarge text editor in Firefox and Netscape.

I am a long time user, of IE. I would like to use Firefox but have encountered a problem.
I am webmaster of several internet websites. When I sign in with the domain owner's name, it usually takes me to a list of icons. Clicking on the file icon, that takes me to the owner's list of internet pages.
From there, I click on any page where I need to work or add something. That brings up the text editor for that page, in which I need to work.
As in all internet pages, on the top right, there appear three boxes.
One to minimize, one to enlarge and one to exit.
When using IE I can enlarge this page, but in Firefox and Netscape, it is faded out and unable to be used.
Is there a fix for this please?

Welcome to the Forum, LizzieD!

LizzieD,

It sounds like the web author has composed the page for IE, and it is not cross browser compliant. If you want to use Firefox, then install the IE Tab extension. It will allow you to view the page as if using IE, as well as download and install your Windows Updates. You can install the IE Tab here:

Thank you so much Ramona. Really appreciate it.
