The scrolling checks box on Github really irritates me. Follow these instructions to make it full height on Firefox.
1. Take this CSS:
.branch-action-item.open > .merge-status-list-wrapper > .merge-status-list, .branch-action-item.open > .merge-status-list {
max-height: fit-content !important;
}
2. Tell Firefox to use the new CSS
Follow the guide here for adding it to the custom CSS. And done, full height checks box!
