while working with more or less 100 tabs it would be very helpful for orientation where you are and to find another open Tab faster and without scrolling all the way from left to right or from right to left. I´m already retired and work since mid 90s with Computers but just for research and information. For over 20years Internet ít´s still annoying to spend time with searching another text-relating open Tab. 

As this will be a challenge for the programmers I just give a first idea:

It should work seperate in the background and should open a MENUE to number each open Tab. Also possible -  it gives a number automatically to each new open Tab. If a TAB must be switched in the line it should get the right consecutive number of the new point within all TABS. ( Best solution)

I´m German lang not perfect english. Hope one can do any workout with this. Thanks and best.

It's not the answer you'd expect

Nevertheless, if you would like to try
Show the number of open tabs on the 'List all tabs' button ?
Color the active tab ?

/* show tab manager button even when tabs aren't overflowing -  
   can instead use browser.tabs.tabmanager.enabled;true as well  
   or skip this part if you want to retain the default behaviour */  
#alltabs-button {  
    display: -moz-box !important;  

/* tab counter */  
#TabsToolbar-customization-target {  
    counter-reset: tabCount;  
.tabbrowser-tab {  
    counter-increment: tabCount;  
#alltabs-button > .toolbarbutton-badge-stack > .toolbarbutton-icon {  
    visibility: collapse !important;  
#alltabs-button > .toolbarbutton-badge-stack {  
    position: relative !important;  
#alltabs-button > .toolbarbutton-badge-stack::before {  
    content: counter(tabCount);  
    border-bottom: 1px solid var(--toolbarbutton-icon-fill);  
    color: var(--toolbarbutton-icon-fill);  
    opacity: var(--toolbarbutton-icon-fill-opacity);  
    position: absolute;  
    bottom: var(--toolbarbutton-inner-padding);  
    left: 50%;  
    transform: translateX(-50%);  
    padding: 0 3px;  

/* Color the active tab */

.tabbrowser-tab[selected] .tab-content {
  background-color: #33cc33 !important; }
.tabbrowser-tab:hover:not([selected]) .tab-content {
  background-color: #cccc33 !important; }
.tabbrowser-tab:not([selected="true"]):not(:hover) .tab-content {
  background-color: #cc3333 !important; }
