X Translator is a browser extension for Chromium based browsers that automatically translates posts on X into Russian. It works across the main feed, replies, and quoted posts, without changing the rest of the site's interface or touching usernames. The translation replaces the original post text directly in place, and a single button lets you switch back to see the original wording. Links, mentions, hashtags, emoji, and line breaks in the original post are all kept as they were. The extension detects the source language automatically, so it is not limited to translating from English, it works with posts written in any language it can detect. The easiest way to install it is through the Chrome Web Store listing. For anyone who wants to install it manually instead, the README explains downloading the zip file from the latest GitHub release, unzipping it, turning on developer mode on the browser's extensions page, and loading the unpacked folder, then refreshing an open X tab. Under the hood, the extension uses Bing Translator's public web interface rather than an official, paid translation API, and does not require an API key to work. The README is upfront that this is not officially supported: if Bing changes that web interface or starts limiting how many requests it accepts, translation could stop working for a while until the extension is updated. Only the text of each post is sent to Bing for translation. Everything else, including any local cache of translations, your settings, and usage statistics, stays stored inside your own browser and is not sent anywhere else. The project includes simple commands for checking and packaging the extension for anyone who wants to build it themselves.
