'List all tabs' button doesn't appear in FF 119

[somepaulo]

Describe the bug The 'List all tabs' button doesn't appear in Firefox 119

To Reproduce

1. Install or update to latest git version of theme
2. Launch Firefox
3. Make sure your tabs bar has enough tabs to overflow
4. See no 'List all tabs' dropdown button

Expected behavior When tabs overflow the tabs bar, a dropdown arrow button should appear revealing a list of all tabs with a few extra options.

Setup information

• OS: Arch
• Installation method: manual install from git
• Firefox version: 119
• Theme version: latest git
• Optional features enabled: none

Additional context Firefox no longer seems to set the overflow parameter to true, it just adds it with an empty value.

For me, removing true on line 476 of tabsbar.css, leaving just the quotation marks, did the trick.
