re: change side cross (close) appears on tabs

[fuzzycat1]

Please could the close tabs cross be moved from the right to the left?

You can do that with CSS. Put this code into your userChrome.css file:

.tab-close-button {
  order: -1;
  margin-right: 5px !important;
  margin-left: -8px !important;
}

If you're not familiar with using CSS, see https://www.userchrome.org/.
