Selenium IDE was deprecated last year - maybe that?

"The bad news: from Firefox 55 onwards, Selenium IDE will no longer work."

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.
