Restoring Multi-Row Tabs in FF 107

Firefox’s update to version 107 destroyed my custom CSS for multi-row tabs. But the internet has an answer. These are the steps:

  1. Go to about:config and turn layout.css.moz-box-flexbox-emulation.enabled to “true” (source of this important advice: here)
  2. Strip out any old multi-row code from your C:\Users\[YOUR USER HERE]\AppData\Roaming\Mozilla\Firefox\Profiles\[PROFILE NAME]\chrome\UserChrome.css file [or create one if this is a fist time]
  3. Replace it with the code at MrOtherGuy/firefox-csshacks [link updated].

Worked for me.
