Multiple functions not working in Developer 139.0b10

[Faedelity]

Describe the bug
I just flipped from Nightly to Developer after switching the other way a while back to stay on a version where multiple tab rows work. Paxmod was working as desired in Nightly, but in Developer, only about half the functions work, and the multiple tab rows function does not work, that being my main use.

• Dynamic Tab Colors: Working
• Display "New Tab" button: Working
• Display Titlebar Buttons: Not Working
• Display Titlebar Spacers: Not Working
• Always Display Close Tab Button: Working
• Compact Tab Grid: Marginaly shifts icon and text left, no other change, regardless of tab size.
• Tab Label Font: Not Tested
• Default Tab Width: No noted effect
• Min Tab Width: Working
• Max Tab Width: Working
• Min Tab Height: No noted effect
• Max Number of Tab Rows: Not Working
• Fit tab lightness to current theme: No Noted Effect
• Min Tab Color Lightness: No Noted Effect
• Max Tab Color Lightness: No Noted Effect
• Custom CSS: Not Tested

Environment
Windows 10 Pro
Firefox Developer 139.0b10, Build ID 20250517142841
Paxmod 3.16, last updated May 26, 2025

Actions Taken
I have uninstalled Paxmod, restarted Firefox, reinstalled Paxmod, fiddled with settings, checked to make sure the variables are set correctly to allow the APIs to install, and looked to see if there are other active issues similar to this. If there are, I didn't catch on.

Weird that it was working at all for you as this addon stopped working from around 131.0a1 almost a year ago on both dev and nightly.
#113

I use this patcher and activate only multi-row tabs:
https://github.com/Izheil/Quantum-Nox-Firefox-Dark-Full-Theme/releases
Paxmod works on latest 140.b3 dev and latest nightly with this patch except some functions that are not important to me like titlebar spacers, display titlebar buttons.

Couple of bugs:

*Pinned tabs are too wide. Need to set max. tab width in Paxmod settings to whatever you are comfortable with. This also will affect all tabs. I set both max and min tab width to 150.
*Min. tab height in Paxmod settings must be set to at least 24 if compact tab grid is selected or tab warping will occur when hovering over them. On my machine at least.
