✨ Added window count in the popup.

✨ Added support for dark mode in the popup.
✔️ This fixed the problem that both the text and background might be dark in some configs.

✨ Preference changes are now reflected immediately.

Interacting with pref controls will have an immediate effect, without having to click a save button, which is therefore removed.
Instead, there is a new undo button, which reverts all the current changes to the state when the pref page was opened.
The undo and reset buttons are more intelligent: they are disabled when they would have no effect.

✨ The extension no longer reloads when saving preferences.
This avoids some flickering, and is a first step towards reflecting changes immediately, without having to click a save button.

✔️ Fixed badge text color being set to black instead of white when resetting preferences to defaults.

After a long delay, version 3.0 is finally here!
✨ More lightweight
❗️ Requires Firefox 63

By raising the minimum version from 52 to 63, I could remove various workarounds and polyfills that were no longer needed.
This made the extension even more lightweight, and will make it easier for me to add new features into the 3.x branch.

✔️ Fixed two issues with SVG icons introduced in version 2.9:
- Numbers with 3 digits or more could be clipped.
- Background color was ignored.

✔️ Dynamic data is no longer inserted into the source code of SVG icons.

Previous versions shouldn't be vulnerable to SVG injection because external data was sanitized before insertion. But the current DOM approach is more robust and will scale better if I add more customization options in the future.

✔️ Fix icon flickering when opening a new window.

Since version 2.0 in Firefox 62+, if Tab Counter Plus was configured to count tabs per window using a SVG counter, when opening a new window you could see the default extension icon appearing for a short period of time before the counter replaced it.

✔️ Workaround for a Firefox bug which broke preferences after saving them in Firefox 52-54.

✔️ Stopped using a new JavaScript syntax added in Firefox 55, so that Tab Counter Plus can work in older versions.

From now on I will make sure to check the add-on works in the first supported version, currently that's Firefox 52.

✔️ A counter configured to count tabs among all windows is now correctly updated when a window is closed.

A regression introduced in version 2.0 prevented it from decreasing.

✨ Badge text color can be customized in Firefox 63+

This uses a new API designed and implemented by me. Currently there is no other add-on providing this functionality!

✔️ Add-on icon is no longer blurry in toolbar

✨ Preferences are now more detailed and easier to understand.

✔️ Dropped the Firefox 62 requirement.

For previous Firefox versions, window-specific counters are polyfilled like in Tab Counter Plus 1.0.

But in Firefox 62+, you will get all the benefits added in Tab Counter Plus 2.0.

✨ Real window-specific counters are now used instead of a hack.

This is a new feature from https://bugzil.la/1419893, designed and implemented by me specifically to enhance tab counters and similar extensions.

I had managed to make flickering negligible in most cases, but there were some edge cases like opening a tab in a non-focused window. This is all fixed in this version.

It also allowed me to remove various event listeners and simplify the code, improving performance.

❗️ This version requires Firefox 62
