X Country Block is now Tamis: same add-on, new name and icon. Your picks and your Focus mode purchase carry over.

New
• Redesigned popup, in light and dark.
• Filtering switch: pause without losing your picks.
• Always show the accounts you choose. Your own posts are never hidden.
• Highlight mode now says why a post matched, with a one-tap "Always show".
• Search understands other names and ignores accents ("usa", "uk", "turkiye", "latam", "farsi").
• 20 regions, including Latin America & Caribbean, Middle East and the European Union.
• Focus mode: an explanation card, a trial countdown, and "Already bought? Restore".
• If Firefox has not given Tamis access to x.com, or a tab needs a reload, the popup says so and offers a button.

Better
• Far fewer wrong matches from profile locations ("In the clouds" is no longer India).
• Indonesian, Hebrew, Kurdish and Chinese posts can now be filtered.
• Posts are filtered before they scroll into view, so the feed no longer jumps.
• When a Focus mode trial ends, filtering pauses instead of turning your list around.
• Lighter on memory and storage. Account data saved by older versions is cleared.

Fixed a bug where selecting a country and continent at the same time would overrule each other
