Starting some weeks ago, I've been having a problem where scrolling with my Mac trackpad suddenly stops working, in a specific Firefox window. It started happening in Firefox 108 (I think), but I don't know whether it's connected to that version of Firefox, or something else. I use the release channel, so now I'm on 110, and it still happens. Using the latest macOS.
Scrolling continues to work in other Firefox windows. It happens once a day or so. I can't find any way to reproduce it manually, or narrow down any particular condition or website that triggers it. The only way I've found to rectify it, is to quit Firefox and re-open it, or else move all the tabs from that window to a new window.
I don't know what else to do to troubleshoot. It's possible it's connected to some extension, but since it happens so rarely, I can't go through and disable each extension to see if it's the cause. I don't see anything in the browser console window that seems relevant. I can't find any bug reports in Bugzilla.
Scrolling is disabled for web pages in all tabs in the window, as well as the sidebar that I use with Tree Style Tab. When I try to scroll, I can see the scroll bar appear on the right, as though it's trying to scroll, but it won't move. I can still move down the page with the spacebar or arrow keys.
