New Update Osprey Browser Protection discussion and updates

[ErzCrz]

I finally made an introduction video for Osprey. Let me know your thoughts:

Great video, Osprey is a great extension I needn't anything else apart from uBlock Origin Lite for blocking ads

Yep. That's the setup I'm using. uBlock Origin for ads, Osprey for phishing threats.

I am curious for some of your reasons why you choose it over the AdGuard Adblocker web browser extension (MV2 or MV3)?

They're mostly interchangeable.

Thanks @Foulest.

I jump back and forth between them, and sometimes trying Ghostery.

I like that Ublock Origin / Ublock Origin Lite have better defaults and is quicker / easier to adjust the filters.

While I am not a fan of the AdGuard Adblocker defaults and how it takes more time et cetera to adjust the filters and settings, along with some bugs. The AdGuard program is the buggiest of them all, I never can use it for long, because of bugs, sadly. I am glad that I have lifetime licenses, so I am not losing money by not using it.

AdGuard Adblocker / AdGuard program (when it works / is not bugging out) has the potential to be the best after adjusting various settings.

AlphaMountain and PrecisionSec now run through our proxy server

If it's for the privacy of the requests, then why just those? And if it's not for privacy, then why is it necessary?

If it's for the privacy of the requests, then why just those? And if it's not for privacy, then why is it necessary?

It's for both privacy and security. User IPs are hidden through the proxy server, and so are API keys which are necessary for the APIs the proxy server calls to function. I might route all traffic through the proxy server entirely in the future, but I've kept the DNS providers local for latency.

Osprey Browser Protection 1.5.0 (released: Mar 23, 2026)

This update addresses CyberDevil's privacy concerns. Now everything is routed through the proxy server.
Your IP is now completely hidden to every provider. Stay safe!

Changes in 1.5.0​

• Moved all URL lookup logic to the proxy server
• Added feedback form that opens when uninstalling
• Added keyboard navigation to all UI elements
• Hardened security of most classes in codebase
• Fixed various issues with the caching system
• Updated Privacy Policy
• Cleaned up code

This update has been submitted to all extension stores.

With this update, every lookup request, including to DNS servers, goes through our proxy server (https://api.osprey.ac) before being sent back to the Osprey client. This ensures that your IP address is never sent to any provider in Osprey's protection options - only to the proxy server, which doesn't log or store IP addresses. Feel free to read the project's Privacy Policy for more information.

Full Changelog: 1.4.9...1.5.0

I tried your new version 1.5.0 in Firefox for Android, but I can't identify other PPs that might be blocking a website,it's almost certainly my fault.
It's easier with a mouse on the desktop version.
It seems to me that any proxy latency, if it works in the Android version as well, is acceptable.
Keep up the good work.
