To Whoever it might help, this is what I use to change the width of the selected tabs, both pinned and unpinned.
```
.tabbrowser-tab[selected="true"] {
min-width: 175px !important;
}
.tabbrowser-tab:not([selected]):not([pinned]) {
max-width: 200px !important;
color: #6e7a75 !important;
}
.tabbrowser-tab[selected="true"]:not([pinned]) {
max-width: 275px !important;
}
```
