| Selenium IDE was deprecated last year - maybe that? - https://seleniumhq.wordpress.com/2017/08/09/firefox-55-and-s... "The bad news: from Firefox 55 onwards, Selenium IDE will no longer work." Alternatives: - https://www.katalon.com/resources-center/blog/selenium-ide-a... My own metrics, comparing attention on Stack Overflow: - Katalon Studio immediately started getting attention on Stack Overflow after Selenium IDE was discontinued. - In Q2 2017 Robot Framework already had more pageviews on Stack Overflow than Selenium IDE. The gap has continued to grow since the deprecation notice. - In any case, Protractor is the one with the most attention on Stack Overflow between these alternatives. - https://imgur.com/a/Jpe9KGl |
Protractor is a test runner for Angular JS that uses Selenium WebDriver to talk to browsers. It's very much alive, as are all the other test runner options (Nightwatch, Cypress, etc).
