User Reviews

Users praise the extension for accurate, fast summaries and translations, with strong YouTube transcript support and rich customization through prompts. It’s valued for context-aware results and open-source Firefox availability. However, recurring concerns center on needing a Gemini API key and confusing setup with inconsistent sources, plus UX bugs around custom actions and options. Mobile users report UI glitches (content overflow, dark mode readability). Some updates temporarily break features like video summaries and trigger 403/API issues, highlighting reliability and documentation gaps. Overall, powerful but with setup and stability caveats.

Pros

High-quality summarization and translation.
Supports summarizing pages and YouTube transcripts/subtitles.
Rich customization via custom prompts and prompt options.
Fast, context-aware summaries on the current page.

Cons

Requires Gemini API key; setup can be confusing and key sources/instructions are inconsistent.
Custom actions/prompts do not always work reliably and documentation is lacking.
Mobile UI issues such as content overflow with large fonts and hard-to-read input in dark mode.
Post-update reliability issues (e.g., video summarization can break; occasional 403/API problems) and guidance gaps.

I love this extension! You have to use Google AI Studio to get your free API key, but once you have that set up, you're good to go. The extension will summarize web pages *and* YouTube videos that have transcripts ready. Huge time-saver.

Is Summarize and Translate with Gemini 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.

Summarize and Translate with Gemini does not require any sensitive permissions.

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.

Summarize and Translate with Gemini is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
