To get eWebedit working in Firefox, you’ll need to install an activex interpreter. This should be automatically installed by visiting this Esker plugin demo page.
Once the demo is working, you’ll need a user agent switcher to fool eWebedit into thinking you are using Netscape 7.
User agent switcher
After restarting Firefox, if you don’t have a Netscape 7 user agent string installed by default.. check under Tools -> User Agent Switcher ->
then you can import mine.
User Agent Strings (Right click -> Save Links As)
Tools -> User Agent Switcher -> Options -> Options -> User Agents -> Import
Select Netscape 7 as your User Agent, visit your page that uses eWebedit, and all should be rosy. You’ll need to switch the User agent to Netscape 7 each time you want to use eWebedit after closing Firefox.
