Browser extensions: permission checks

Basic check order

1. Start from the browser vendor, official extension store, or the software vendor page that links to the store listing; AppVeriq Guide does not host extension packages or installers.
2. Confirm the publisher, extension name, icon, verified domain, extension ID, install count, update date, support link, and privacy-policy link before adding it.
3. Read permission prompts literally: page read/write access, clipboard access, downloads, file URLs, native messaging, cookies, identity APIs, tab access, screen capture, and all-site access can expose sensitive data.
4. Check whether the extension sends page contents, prompts, screenshots, transcripts, coupons, analytics events, or form fields to a cloud service before using it on work pages.
5. Prefer least-privilege settings such as click-to-run, specific-site access, managed browser profiles, allowlisted extension IDs, and separate personal/work browser profiles.
6. For password managers, VPNs, AI helpers, coupon tools, meeting assistants, grammar tools, and screenshot extensions, review account ownership, data upload, retention, sharing settings, and admin controls before sign-in.
7. For business use, document the approved extension ID, browser store URL, publisher, allowed profiles, permission scope, data categories, update policy, exception owner, and removal/offboarding owner.

Cautions and operating tips

• An official browser extension store reduces some risk but does not prove that every listing is appropriate for work data or regulated customer information.
• A fake or abandoned extension can imitate a trusted brand name, icon, or keyword; compare the listing from the vendor page when possible and record the exact extension ID.
• Extensions with access to all websites can see internal dashboards, customer records, source-code tools, SaaS admin pages, email, and login screens that ordinary desktop apps may never touch.
• AI, meeting, grammar, and screenshot extensions often create a data-processing question before they create a download-safety question; check retention, training, and workspace controls.
• Browser sync can reinstall extensions on new devices, so removal and offboarding should include synced profiles, managed policies, and personal-account cleanup.
