1443249 - Search doesn't find occurrence when scrolled away in a div

Status: RESOLVED DUPLICATE of bug 1436431

(Core :: Find Backend, defect)

Description

[Niklas Hambüchen]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180305100134

Steps to reproduce:

When I browse to https://github.com/ceph/ceph-ansible/issues/632 and search (Ctrl+F) for "notinstalled".

I'm using Firefox Nightly 60 on Ubuntu 16.04.


Actual results:

, it claims that there's no occurrence on the page, even though there is, namely in the the first code box on that page. But the string "NOTINSTALLED" in that code box is not visible in the viewport because to see it I have to scroll that code box to the right.

When I scroll the text box to the right, and search again, Firefox finds the string.


Expected results:

Firefox should find the string in all cases.

I cannot reproduce this bug from a clean profile with the same Firefox version.

When I start `~/opt/firefox-nightly/firefox/firefox -profile tmpprofile/ --no-remote --new-instance` and go to the page, the problem disappears.

In my normal profile, the problem persists even when I restart Firefox in safe mode (all extensions disabled).

It doesn't seem to be caused by my settings either: When I copy `prefs.js` from my profile into `tmpprofile` and run `~/opt/firefox-nightly/firefox/firefox -profile tmpprofile/ --no-remote --new-instance`, then the bug is still not present.

How can I debug this?

Is there other state in Firefox beyond prefs and plugins that may cause this difference?

It also works for me. I can only reproduce this if I switch findbar.modalHighlight to true, and even then only if I type very quickly.

Even with a new profile and on 60 i can still find this bug!
however @Gingerbread Man has a point that if typing manually it does find the "notinstalled", but if one uses copy/past (similar to writing too quickly or using barcode scanners) it is unable to find the string

Still, and !funny enough, as i mentioned in bug 1436431, in my case even typing slowly it does not find the string. But scrolling a bit in any direction (but still having the string "hidden") will allow firefox to find it

Works for me. Even with findbar.modalHighlight = true, Ctrl+F then Ctrl+V is fine.

Duping to bug 1436431 as per bug 1448087, comment 3.

Please test the latest Nightly in a brand new profile and reopen if the issue is still reproducible.
