Additional context
I tried using the PowerShell install, and I chose the Update option before I tried to install manually.

Never mind, it seems that whatever was causing it is fixed now.

@black7375 I have the same issue after upgrading to v5.2.1. Using Lepton Photon Style, all my prefs in user.js are default (same as in release archive). My system is Linux but the excessive contrast is present in all themes.
System theme:

Dark theme:

Light theme:

Alpenglow:

None look like the reference image:

[black7375]

@Roy-Orbison
This is because of the configuration conflict.

• weird line separators between tabs #393 (comment)
• Tab highlights turned weird; lepton and lepton-photon seem to be identical; tab overflow issue #395 (comment)

A restart is required after setting the technical limit, and for file user.js, an explicit value must be set.

• https://github.com/black7375/Firefox-UI-Fix/wiki/Options#important

I think you used original's setting file, not photon-style's configuration file.

[Roy-Orbison]

@black7375 Thank you for looking into this but the problem is not quite as you describe. I had restarted twice and ensured my user.js was identical to your distributed photon style version, whilst Firefox wasn't running. The cause was that I had tried your other styles, and commented lines in user.js did not remove the prefs from my profile (as stored in prefs.js).

Some of your options seem to be binary, e.g. userChrome.tab.static_separator and userChrome.tab.dynamic_separtor look like two versions of the same preference, because they should always have the opposite value. They should probably be a single pref, but changing that now wouldn't be backwards-compatible.

Any preferences that conflict should still be set, but to their opposite rather than commented out, e.g.:

// Original, Proton
// user_pref("userChrome.tab.dynamic_separtor",        true);
// user_pref("userChrome.tab.static_separator",       false);
// Photon
user_pref("userChrome.tab.dynamic_separtor",          false);
user_pref("userChrome.tab.static_separator",           true);

or

user_pref("userChrome.tab.dynamic_separtor",          false); // Original, Proton: true, Photon: false
user_pref("userChrome.tab.static_separator",           true); // Photon: true, Original, Proton: false

[black7375]

Any preferences that conflict should still be set, but to their opposite rather than commented out, e.g.:

Yes, exactly.
I wish it could be set using numbers(e.g. userChrome.tab.separator, 0[None], 1[Dynamic], 2[Static]), but it's impossible.

[Roy-Orbison]

I mean the files you distribute should not have commented lines, they should all be set even if to false, at least for the important ones at the top.

[Roy-Orbison]

I fixed my problem not by un/commenting or modifying anything in user.js, but by toggling the existing prefs to false on the about:config page.

[black7375]

@Roy-Orbison Yes, Your right.
Explicit false is a policy that can reduce mistakes.
I'll commit right away. Thank you for your advice.
