The Tomba extensions need a few permissions to find emails for the page you're viewing. Tomba has extensions for Chrome, Edge, Firefox, Opera, Safari, Thunderbird and NAVER Whale.

See the current tab. Your browser may call this "Read your browsing history". When you open the extension, it reads the address of the current tab, so it can search that company or the author of that article. It also updates the Tomba icon and opens Tomba pages in new tabs.

Run on the pages you visit. A small script runs on every site. It tells the extension whether the page is an article. It also highlights an email address on the page where we found it. It sends nothing by itself.

Read LinkedIn and Apollo pages. When you ask the Tomba panel to find an email or collect a search, it reads the page you're viewing, using your own sign-in.

Add the panel to open tabs. After you install or update the extension, it adds the Tomba panel to LinkedIn and Apollo tabs that are already open. You don't need to reload them.

Connect to Tomba. The extension sends your searches and verifications to api.tomba.io, and shows the answers.

Store data. The extension keeps your settings and the connection to your Tomba account. It also keeps LinkedIn results for a short time, so the same profile isn't searched and charged twice.

Add right-click items. You can verify, search or find the author of text you've selected, or validate a phone number. To remove these items, turn the menu off in the extension's settings.

The Thunderbird add-on asks for less, because it works with your mail and not with web pages. It needs to store data, see the current tab, read the message you open and connect to Tomba. It reads the message so it can show you the people at the sender's company.
