Add this CSS to your user stylesheet to separate favorite/uploaded tags into columns.

For Firefox userContent.css:

@-moz-document domain(e621.net) {

.tag-column:first-child {
height: auto !important; max-width: 45em !important;
column-count: 4 !important; -moz-column-count: 4 !important; -webkit-column-count: 4 !important;
column-gap: 10px !important; -moz-column-gap: 10px !important; -webkit-column-gap: 10px !important;
}

}

Adjust max-width or column counts if needed.
