Features & Capabilities

Immersive Translate Ultra is a cutting-edge Chrome extension designed to provide an immersive bilingual translation experience for web pages. It intelligently identifies the main content areas, displaying both original text and translation side-by-side by paragraph to enhance readability. Unlike generic translators, it avoids translating irrelevant areas of the page, similar to browser immersive reading modes.

This extension supports over 10 major translation services including Deepl, Google, Bing, Tencent, Youdao, and others. It is optimized for popular sites such as Twitter, Reddit, Gmail, YouTube, and Telegram for a superior translation experience. Advanced features include customizable paragraph length, bilingual PDF translations, and foreign e-book reading compatibility via EPUB online readers. Privacy-conscious users can rest assured as no personal data is collected, though content is sent to third-party translation APIs for processing.

User Reviews

Users commonly report the add-on works well and outperforms some alternatives, but multiple reviewers cite subtitle/language-handling bugs, translation failures on certain sites, and regressions after updates. Several users also complain about paywalled features and request more free functionality.

Pros

Reliable/effective in many cases — multiple users said it works perfectly or is the best they found
Performs better than some popular alternatives (one reviewer switched from a widely-used add-on that failed)
Generally liked by several users who left simple positive reviews ('good','works well')

Cons

Subtitle and language-handling problems — forced wrong subtitle language for some users and exported bilingual subtitles were merged/changed after an update
Translation failures on some sites or inputs (e.g., failed Japanese romaji → English; translation engines appeared to change text but not produce proper translations)
Too many paid/locked features; users request more free functionality
Updates have introduced regressions or negative changes (slower performance, changed export behavior)

功能越放越多，但全是穷逼用不了的功能，还更卡了。

First I tried the other add-on, the one with 80,000+ users. It didn't work at all. I installed this one, and it works perfectly. I would say, above expectations

Is Immersive Translate Ultra Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Immersive Translate Ultra requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Immersive Translate Ultra may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
