So would anyone in the business, but that never was the case. This one was just a simple css coding job and Dao (one of the main Mozilla devs) saw it as such. But no, it had to be the usual Mozilla stuff of decide first, then hunt around for a reason, then spend ages justifying it...and then being defensive.

Mozilla are actually very good at being defensive, which is fine but this is the major Open Source browser out there. So, if Firefox is not going to look after the needs of minorities, then who is?

For example, the needs of children, special needs and the aged forgetful were being met by 'Icons with Text' and 'Text Only' modes, so 5 years back Mozilla removed them. Where was the mythical triple code stack then, considering the code is still in there 5 years later and can be brought back to life with userChrome.css? That removal wasn't a business decision, that was downright nastiness.

This is the reality of it all - the original Bug Report - before the spinning started.

Thanks for that "the original Bug Report" link frank, a most interesting read in parts.

I don't usually have time to wade through such things, but in this case it was worth the effort.
I'll not be making additional comments about that report as it's now old and OT news... and I don't want to get thrown off here as well... ;-)

Very informative thread for help with the userChrome.css code to work with Firefox 65. :)

Many thanks to everyone for their helpful tips in this thread. :)

This is my current userChrome.css file.
Code: Select all
@namespace url("");

/* TABS on bottom */
#navigator-toolbox toolbar:not(#nav-bar):not(#toolbar-menubar) {-moz-box-ordinal-group:10}
#TabsToolbar {-moz-box-ordinal-group:1000!important}

#TabsToolbar {
 position: absolute !important;
 bottom: 0 !important;
 width: 100vw !important;
#main-window:not([chromehidden*="toolbar"]) #navigator-toolbox {
padding-bottom: var(--tab-min-height) !important;
#tabbrowser-tabs {
  width: 100vw !important;
  #TabsToolbar > .toolbar-items {
    padding-top: 0 !important;
   margin-top: 0 !important;

#PersonalToolbar { /* bookmarks toolbar */
  -moz-box-ordinal-group: 2 !important;
#TabsToolbar { /* tab bar */
  -moz-box-ordinal-group: 3 !important;
.bookmark-item[container], treechildren::-moz-tree-image(container) { fill: brown !important;
  fill: brown !important;
#back-button {
fill: green !important;
#forward-button {
fill: green !important;
#PanelUI-menu-button { display: none !important;

It's now very close to what I want my Firefox 65 to look like.
Anything I'm missing in the code here or that needs to be added/edited/moved/removed ? :-k
Thanks! :)
