Thanks for the response. To be fair, this behaviour is so unexpected (like, why is it the third occurrence and not the second?) that I really thought that I was very tired yesterday evening, and hoped that the bug would have disappeared today. But… no. It is still there. Sorry.
I tried to reproduce the behaviour at work, and with Firefox on my phone, and it behaved normally in these other devices. I guess that it’s not the same version of Firefox (and/or language settings, or even system). On my home computer, it’s still there. By the way, the index of the occurrence is correctly given: it starts with “Occurrence 1 sur 4”, then “Occurrence 2 sur 4”, then “Occurrence 4 sur 4”, then “Occurrence 1 sur 4 Bas de la page atteint, poursuite au début”. This time, it did not reach occurrence 3 even at the first cycle. I wasn’t aware of the Ctrl+G shortcut ☺ Thanks! The behaviour is the same with it than by clicking on the down arrow in the interface. I also tried with other searches (on the same webpage), like “function”. This time, there are 17 occurrences, and there are more misses (using Ctrl+G): it misses this time the 8th, 13th, and 16th occurrences. It is even less expected than before ☹ It is very difficult to understand the pattern there. When I try looking for “Sw”, I get 9 occurrences, and no miss: all 9 occurrences get to be reached one after the other. The fact that the bug does not appear on other systems or on a fresh install as you did seems to indicate that something is wrong with my system :-\ I did not remember having changed any behaviours of Firefox in a strange way. I did install some plug-ins in Firefox, though: maybe the bug comes from one of these? The stranger thing is that the bug seems to be deterministic in my computer: it’s always the third occurrence for the “addEventListener” search and the 8, 13, 16th occurrences for the “function” search. This seems to indicate that it’s not an issue with my keyboard accidentally pressing twice Ctrl+G or something like that. This is strange :-\ If I can help, don’t hesitate to ask for more details. But again, this bug is actually more funny than harmful.

Status in firefox package in Ubuntu: Incomplete Bug description: Hi, This is probably the most unexpected bug that I have ever seen. Fortunately, it is benign. How to reproduce: - Go to the webpage https://www.w3schools.com/howto/howto_js_autocomplete.asp - Type Ctrl+f to look for a word through the webpage. - Search for addEventListener. Firefox successfully found 4 occurrences on the webpage. - Using the arrows next to the search box, loop through all occurrences. Firefox then jumps to the following occurrences, in order: 1. inp.addEventListener("input", function(e) { 2. b.addEventListener("click", function(e) { 3. inp.addEventListener("keydown", function(e) { (In my screen is, it was hidden by the message about cookies: scrolling down by 1cm makes it appear.) 4. document.addEventListener("click", function (e) { 5. First occurrence again: inp.addEventListener("input", function(e) { 6. Second occurrence again: b.addEventListener("click", function(e) { 7. Firefox then directly jumps to the fourth occurrence, missing the third one: document.addEventListener("click", function (e) { 8. (goes back to 5). In other words, although the first cycle through all occurrences was correct, the following cycles completely miss the third occurrence! I have restarted Firefox and still get this behaviour. If instead of clicking on the “down” arrow to look for the second occurrence one looks backwards with the “up” arrow, then it is “b.addEventListener("click", function(e) {” instead of “inp.addEventListener("keydown", function(e) {” which is missing from the loop: it seems that whenever cycling through all occurrences of a search in a webpage, if there are only four occurrences, then the third one is never reached except in the first cycle. I am sending a screenshot of the situation. This is a very unexpected behaviour, but of very minor consequence: there is no need to place a high level of importance for this bug, I guess.
