CTRL+F (browser "search in page") is broken on Linux Firefox
Describe the bug
If I press CTRL+F on Firefox to open the "search in page" field it instead advances the caret by one step if a cell is selected
To Reproduce Steps to reproduce the behavior:
- Open a cell, make sure it has focus and the caret
- press CTRL+F (which should open the "find in page" functionality)
Expected behavior
"Find In Page..." to be opened
Desktop (please complete the following information):
Linux Firefox 89
This is in 'experimental features'
So I found that one way to make the find-in-page open again is to first click on the right side of a cell, like where I pointed my cursor in the screenshot:

After doing that CTRL+F works as expected. Does a cell having focus perhaps capture the keyboard input in a way that intervenes?
However, even though we can open the find-in-page this way, the search behavior is very unreliable: it can't really "forward" search, only "backwards", and even then it add/skips items half of the time.

Note how the number of found matches toggles between five and six. Chromium-based browsers show the correct seven matches in this notebook I tested without any hassle:

(remember, this issue shows up in Firefox, Chromium-based browsers don't seem to have this issue - I can't speak for any other browsers than those two)

Reported again in forum https://talk.observablehq.com/t/ctrl-f-moves-the-cursor-forward/5681
We now have a dedicated Find and Replace feature for notebooks https://observablehq.com/@observablehq/release-notes#cell-957
Why's this closed? It seems like Ctrl+F is still overridden to be "move cursor forward 1 step" (with Ctrl+B being "move cursor back 1 step"), but would anyone ever want that feature? Surely that's what arrow keys are for. I'd much rather have it remain as the native browser find-in-page feature, which is sometimes desirable to use over the custom Find-and-Replace (e.g. I want to search the literal displayed text content of the page). I know I can also use F3, but Ctrl+F is more convenient.
Agreed. It should not have been closed. Apologies.
@lionel-rowe Do you see the same override and behavior in the CodeMirror demo editor on https://codemirror.net/ ?

No. For me (Chrome 119, Windows 11), that demo editor does override Ctrl+F, but the new functionality is the code editor's own find-and-replace, rather than moving the cursor.
