Optimizing Firefox with Kaspersky Protection 2021: Performance & Security Notes

Optimizing Firefox with Kaspersky Protection 2021: Performance & Security Notes

Overview

Kaspersky Protection 2021 is a browser extension that works with Kaspersky desktop apps to provide Safe Money, Safe Browsing, Private Browsing, and Anti-Banner features. It integrates tightly with Firefox and requires permissions to access tabs and page data to perform protections.

Performance tips (reduce impact)

1. Keep extension + Kaspersky app updated — updates often include performance fixes.
2. Disable unused features in the extension:
   • Turn off Anti-Banner if you use another ad‑blocker.
   • Disable Private Browsing notifications if you don’t need site-tracking alerts.
3. Limit site access where possible:
   • In Firefox, set the extension’s site permissions to “On click” for sites you rarely visit to avoid constant scanning.
4. Manage Safe Money rules:
   • Keep Safe Money limited to only the payment/bank sites you use; many rules increase checks and overhead.
5. Avoid redundant extensions:
   • Remove overlapping security/privacy extensions (other antiviruses, multiple ad blockers) to reduce CPU/memory and conflict risk.
6. Enable hardware acceleration in Firefox when available — may reduce UI lag when many extensions are active.
7. Monitor resource use:
   • Use about:performance and about:memory in Firefox to spot the extension’s CPU/memory usage; restart Firefox if memory grows large.
8. Restart Firefox periodically if you notice slowdowns (especially after heavy browsing sessions).

Security best practices (keep protections effective)

1. Keep Kaspersky desktop app running — the extension delivers full functionality only when paired with the desktop product.
2. Enable Safe Browsing and Safe Money for banking/payment sites to protect credentials and block malicious redirects.
3. Review extension permissions regularly — the extension needs broad access to protect pages, but confirm it’s still required and from the official source.
4. Install the extension from Mozilla Add‑ons or Kaspersky’s official site
