Best Firefox Extensions for Reverse Image SearchReverse image search is a powerful way to find the origin of an image, locate higher-resolution versions, verify authenticity, or discover visually similar images. Firefox supports several extensions that make reverse image searching fast and convenient. This article covers the best Firefox extensions for reverse image search, how they work, key features, installation tips, privacy considerations, and recommended use cases.
What to look for in a reverse image search extension
When choosing an extension, consider:
- Supported search engines (Google, Bing, TinEye, Yandex, Baidu, etc.).
- Ease of use (context-menu integration, drag-and-drop, keyboard shortcuts).
- Image source options (search by URL, upload, or direct from page).
- Batch or multi-image support.
- Privacy (whether the extension uploads images to third-party servers).
- Customization (ability to add/remove engines or change default behavior).
Top Firefox extensions for reverse image search
1) Search by Image (by Google — unofficial alternatives)
Search by Image style extensions let you initiate a reverse search directly from the context menu. Because Google doesn’t offer an official, full-featured Firefox extension, several community-made add-ons replicate the functionality and add other engines.
Key features:
- Right-click context-menu option “Search image with…”
- Option to search via multiple engines: Google, Bing, Yandex, TinEye
- Paste image URL or upload image
- Choose default search engine
Best for: users who want quick access to Google-style reverse image search from any page.
2) TinEye Reverse Image Search
TinEye is a dedicated reverse image search engine known for tracking image usage and finding exact matches. The TinEye add-on integrates search via the context menu and toolbar.
Key features:
- Searches TinEye’s index for exact matches and modified copies
- Browser button and context menu integration
- Ability to upload images or use image URLs
Best for: locating exact copies, finding where an image has been used, and tracking image versions.
3) RevEye Multi-Search (or similar multi-engine addons)
RevEye and similar multi-search add-ons let you search an image across several engines simultaneously. They open results in separate tabs or a combined interface.
Key features:
- Supports Google Images, Bing, Yandex, TinEye, and others
- Multi-tab results or a pop-up results panel
- Configurable engine list and default behavior
Best for: researchers who want broad coverage without manually repeating searches.
4) Image Search Options
Image Search Options-style extensions focus on configurability. They let you add custom search engines and manage which engines appear in the context menu.
Key features:
- Add custom reverse-image search URLs
- Reorder and enable/disable engines
- Keyboard shortcut support and context-menu integration
Best for: advanced users who prefer custom engine lists or niche engines (e.g., region-specific search).
5) Search by Image (Context Search Integrations)
Some general “Context Search” addons, which let you search selected text or links across multiple engines, include image search modules or can be extended to support image reverse search.
Key features:
- Unified context-menu search for text, links, and images
- Highly configurable engines list
- Integration with other search workflows (bookmarks, quick commands)
Best for: users who already use context/search extensions and want to add image search capability without extra add-ons.
How these extensions work (brief technical overview)
Reverse image search extensions generally operate in one of these ways:
- Send the image URL to a search engine by building a query URL and opening it in a new tab.
- Upload the image to the engine’s upload endpoint via a background request (some engines require an upload).
- Use the browser’s context menu to capture images from the page and pass them to the extension logic.
- Some extensions can encode the image as base64 and send it if the engine supports data-URI uploads.
Privacy note: uploading an image sends that image (or its URL) to the chosen search engine. If privacy is a concern, prefer engines with clear privacy policies or avoid uploading sensitive images.
Installation and setup tips
- Install only from the official Firefox Add-ons site to reduce risk of malicious extensions.
- Check permissions before installing — reverse image extensions typically request access to read page content and open new tabs.
- Configure the default engines and order after installation to match your workflow.
- If you use multiple engines, enable multi-tab opening so results load simultaneously.
- For frequent use, set a keyboard shortcut in Firefox’s Add-ons Shortcuts page.
Privacy and security considerations
- An extension may send images or URLs to third-party search servers—avoid uploading private or sensitive images.
- Review the extension’s developer and user reviews for reports of unwanted data collection.
- Use extensions that let you control or restrict which engines are used.
- If maximum privacy is required, consider performing manual searches using local image tools or trusted, privacy-focused engines.
Quick recommendations
- For exact-match detection and usage tracking: TinEye.
- For broad coverage across many engines at once: RevEye (multi-engine).
- For Google-style searches integrated into the context menu: Search-by-Image community addons.
- For customization and adding niche engines: Image Search Options-style extensions.
Example workflows
- Find a high-res version: right-click image → choose Google/Bing → filter results by size.
- Verify image origin: search with TinEye and check earliest match dates.
- Search across engines quickly: use RevEye to open results from Google, Yandex, and TinEye in separate tabs.
