[userChrome.js] Multiple rows of tabs

[Merci-chao]

Hello folks,

I made an userChrome.js script for multiple tab rows:

Highlights

• Tab-dragging animation is available in multi-row mode.

• While the tab bar is scrollable, pinned tabs remain pinned and placed in a compact grid layout, allowing you to have numerous pinned tabs.

• Maximize space utilization, e.g. fully utilize the space under the window control buttons.

• Highly integrated with Firefox's well-designed behavior, allowing Firefox to support multiple rows like native.

• Compatible with themes even if you have massive rows.

Compatibility

• Firefox 115, 133 and 134 Beta, for Windows 7 to 11.

• Support general script loaders, like xiaoxiaoflood's userChromeJS.
