https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=29578 --- Comment #5 from Andreas Roussos <a.roussos@dataly.gr> --- Hi David! Thank you very much for your interest in this bug report, and the detailed response with your findings. My screenshots were taken using Firefox 94.0.2 on Windows 10 64-bit. Today I fired up an Ubuntu 18.04.6 LTS Desktop in a Virtual Machine, and using the live session user (i.e. no O/S install was performed) I was actually able to reproduce the problem outlined in this Bug's Decription on both Firefox 92.0 (the version shipped with the O/S) and the latest Google Chrome 96.0.4664.45 (official build, downloaded from [1]). I attach two new screnshots from the OPAC, illustrating the problem with the disappearing "Highlight"/"Unhighlight" button.
