Conflict with Colorful Tabs

[NormG1]

Colorful Tabs is a very popular add-on.

When used without Tab Center on the side, the tabs are colored per the preferences in Colorful Tabs and the text is BLACK.

Having Tab Center move the tabs to the side results in WHITE text which very hard to read.

There is no preference for tab text color that a novice could adjust.

So I can only assume this is a bug, either in Colorful Tabs or Tab Center

More like a case of “everyone does their own thing, and goes in different directions”. One of the two add-ons, or maybe both working together, could chose to actively be compatible with the other. But consider that each add-on already has to be compatible with standard Firefox theming, which includes:

• the default theme, which is actually a theme with platform-specific variants for Windows, Linux and macOS;
• the compact light theme;
• the compact dark theme;
• lightweight themes, which apply a background color and image, and change most elements to translucent, and the text and icons to white-with-dark-shadow.

So adding to this list of 4 things to be compatible with is probably not a priority, which is why TabCenter is incompatible with most add-ons which change or style the tab strip: https://github.com/bwinton/TabCenter#incompatibility-notes

With its 200k users, maybe compatibility with ColorfulTabs is worth a look. But without a common strategy with the ColorfulTabs author it's hard to make a working fix.
