Hi, It sounds like you may be seeing the result of a known issue with Firefox and the X-Mouse Button Control software on your computer. This is from the [https://www.mozilla.org/en-US/firefox/110.0/releasenotes/ Firefox version 110 release notes]: ''Note: A bug in the popular X-Mouse Button Control (XMBC) tool may cause mouse wheel scrolling to stop working. The author(s) are working on an update. Meanwhile, scrolling can be restored by reconfiguring XMBC: either disable the Make scroll wheel scroll window under cursor option in the global settings, or enable the Disable scroll window under cursor option if using a custom profile for Firefox.'' For more information, please see the [[X-Mouse Button Control in Firefox 110]] support article.

An updated version of X-Mouse Button Control (XMBC 2.20) has been released. Issues with Firefox 110 should be fixed. To learn more, see https://forums.highrez.co.uk/viewtopic.php?t=4682
