Firefox version 59.0.2 installed on Windows 10 pc. Selenium ide version 3.0.1

Able to record user actions and save project with test script. But on replaying the script, the ide window goes blank and firefox window displays a message "moz-extension://7a9b47b2-f156-4597-a974-ca81cafd892b/assets/bootstrap.html" in the address bar and "Preparing to run your test" on the browser page and it stays like this forever.

On a side note, the plugin for chrome seems to be working so far :)

When I start a selenium test suite using a .side file, the UI disappears and goes blank. The tests still run, but the extension window has no visible content, and when it finishes, I can't see the test results. Using Firefox 59/60

Finally Back!

I'm not able to use existing test suite created by earlier version of Selenium IDE, also I didn't find any options for using user-extensions.js
One would expect the newer version to have more features and allow some level of compatibility for existing scripts. The real users of Selenium IDE doesn't just record and playback, we create our own custom javascript methods making it more dynamic. I'm not sure if this new version of Selenium IDE is for existing user..or just to get new users to start using this add on. It's a sad day :((

Helping and easy use

This new version is janky. Each save triggers a download. Record doesn't record "Opens" only clicks.
