Thanks for the report Martin. I am unable to observe the issue you describe, I tested in an up-to-date stock Ubuntu 18.04 virtual machine with the same version of firefox, and cycling through the search results for "addEventListener" on that page works normally here.
Can you try cycling through the results with the Ctrl+G keyboard shortcut instead of clicking on the down arrow, and let us know whether you're seeing a different behaviour? ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835467 Title: Repeatingly looking for the next occurrence of a word search in a webpage misses one occurrence.
