Features & Capabilities

The DeepL Translate Search Plugin enhances your translation experience by automatically detecting and filling in the source language field based on the URL fragment when you open a DeepL page. Since DeepL doesn't support specifying "Detect language" in the URL, this extension bridges that gap seamlessly, ensuring quick and accurate translations every time.

With this plugin, you can translate specified text effortlessly without having to manually set the source language. It optimizes your use of DeepL, making translation tasks faster and more convenient directly within your browser.

User Reviews

Users appreciate that the plugin replaces '+' signs with spaces and integrates DeepL Translate into Firefox's search. However, multiple reviews highlight problems such as inability to set the default target language, unreliable performance in Firefox, and defaulting to undesirable language pairs. Users request features like language shortcut commands and better auto-detection behavior to improve usability.

Pros

Replaces '+' signs with spaces in search queries, improving readability.
Supports auto-detection of source language when configured properly.
Provides direct integration with DeepL Translate through Firefox search functionality.

Cons

Cannot set or customize the default target language, leading to incorrect translations based on IP location.
No longer works reliably in recent Firefox versions as expected by some users.
Defaults to 'English to Spanish' translation instead of 'Auto to last used target,' reducing usability.
Lacks convenient shortcuts (like '@t') for quick translation from the address bar.

Is DeepL Translate Search Plugin 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.

DeepL Translate Search Plugin requires a few sensitive permissions. Exercise caution before installing.
