Browser extensions can read and change the pages you visit, including trading and banking pages. That makes them powerful and, when badly made or malicious, dangerous. This page sets out how to judge any extension that claims to help with trading. It names no extensions and does not review any.
What an Extension Can See
Many extensions ask for permission to read and change data on the websites you visit. With that access a malicious extension could capture what you type, change what a page shows, or send details elsewhere. A trading helper that requests access to every site is asking for more than most functions need. Treat broad permissions as a reason to stop and ask why.
Browser Extension Self-Check
A ticked box is your own answer, not verification, and the count is not a score or a safety rating. Nothing is saved or sent from this page.
Red Flags
- Promises of guaranteed wins or automatic trading profits; see guaranteed returns claims
- Requests to install from a link in a chat, advert or video rather than from the browser's own store
- No clear publisher, support contact or privacy notice
- Reviews that look copied, or that appear all at once; see fake reviews warning signs
- Requests for your platform login details outside the platform itself, a pattern described in phishing scam warnings
Reducing the Risk
Install as few extensions as you can. Use a separate browser profile with no extensions for sign-ins to trading and banking sites. Review installed extensions regularly and remove those you do not use. Keep the browser updated, and check the permissions again when an extension updates. For how services should handle your data, compare the answers with broker data security standards.
What to Use Instead
Charting, calculators and journals can run as ordinary web pages or in your platform without an extension. The calculators and trackers on this site, for example the trading journal tool, run in the page and need nothing installed.
Limits
This page cannot confirm that any extension is safe or harmful, and browser menus differ. Use your browser's help pages for exact steps. If you think you installed something harmful, change your passwords from a clean device and see how to report a scam.
Frequently Asked Questions
Can an extension steal login details?
A malicious one with broad access could. That is why permissions matter.
Are extensions in an official store always safe?
No. Store listings reduce but do not remove the risk, so still check permissions and publisher.
Do I need an extension to trade binary options?
No. Trading and most tools work in the page or platform without one.
What should I do after installing a bad extension?
Remove it, change passwords from a clean device, and review your accounts. See how to report a scam.
