What it does
One clear lookup purpose
The Funds extension recognizes mutual fund tickers and names and returns AUM / fund size context with direct links into Marketcaper comparison pages.
Selected text
Local first, click to send
Selected text is inspected locally for a possible funds catalogue match. It is sent to Marketcaper only after you click the icon or use the right-click lookup action.
Permissions
Only what the feature needs
Browser permissions support selection lookup, the context menu, saved preferences, and requests to Marketcaper. They are not used for ads or background page scraping.
Privacy
No account required
The extension does not require a Marketcaper account, does not sell selected text, and does not use selected text for advertising.
Review notes
Why the extension asks for browser permissions
Extension code is bundled in the browser package. Requests to Marketcaper return lookup data, not remote executable scripts.
Content script on webpages
Needed to place the small Marketcaper icon beside selected text. The extension filters selections locally and does not read whole pages.
Context menu
Adds the right-click Marketcaper lookup action for selected text when you prefer not to use the floating icon.
Storage
Remembers your enable or disable preference for selection detection on your browser.
Active tab and scripting
Supports the right-click fallback on the current tab when the content script needs to be loaded safely.
marketcaper.com access
Used only to request a category-scoped lookup after you click the icon or use the context-menu action.
FAQ
Questions before installing
Does this extension include ETFs?
No. This package is for mutual fund results. ETFs have their own Marketcaper extension and compare-tool landing page.
Does Marketcaper show price for funds?
When the catalogue has a usable NAV or price, the result card shows it beside the fund-size metric.
