Read the permission scope
Check whether the extension needs access to the current page or to every website you visit. Identify the operator and read its privacy information. A familiar logo or search-engine name in the title does not establish an official relationship.
Compare the simpler route
- Try the service's own website first.
- Check what the extension adds to your workflow.
- Review requested permissions before installation.
- Remove extensions you no longer need.
For a regular source-checking workflow, a context-menu shortcut may save time. For one photograph, the same shortcut may not justify broad access to unrelated pages.
Evaluate results independently
The extension interface does not tell you how comprehensive the underlying index is. Check source links and provider terms just as you would in the browser. Avoid sending private page content merely because an extension offers a one-click search button.
