I had the same problem, SeleniumIDE flow control fixed it: https://addons.mozilla.org/en-US/firefox/addon/flow-control/?src=dp-dl-othersby

I didn’t install Flow Control. The problem also went away after installing the following extensions: Don’t ask me why (or if you need both or just one). (From Mozilla: https://addons.mozilla.org/en-US/firefox/search/?q=selenium)

Highlight Elements (Selenium IDE)
Selenium IDE: Implicit Wait

I found this out because a friend had the error and I did not (I had the two extensions installed already). Later, I installed Firefox fresh on Ubuntu, and the error appeared. After installing the two extenstions, the error no longer presented.
