2. Clicking on the format button produced the error

3. clicking on the Clipboard produced the error

4. closing the IDE window produced the following error
   There was an unexpected error. Msg: TypeError: this.app is undefined

Update Firefox.

Selenium IDE development has been discontinued. No more new features and no bug fixes. From Firefox 55 onwards, Selenium IDE will no longer work [1]. The last supported version is Firefox ESR 52.

Yes, we've started a project to develop a new tool that should replace Selenium IDE. Follow #4406 for the progress.

Sorry this issue has not beed properly and timely addressed, and thank you for submission!
