Disabling content blockers in Safari Settings or on the website in Safari also disables DeclarativeNetRequest redirects, even though DNR is from the Safari web extensions API rather than the Safari content blockers API.
I can reproduce this bug in Safari 26.1 on macOS and iOS. I don't know when the bug was introduced.
Steps to reproduce:
1) Download the sample Xcode project from https://bugs.webkit.org/show_bug.cgi?id=303118 (DNR rules are not applied to a private window if Safari opens with a non-private window and vice versa)
2) Unzip, build, run, and enable the attached Safari extension DNRProfilesBug
3) Open https://gs.statcounter.com/detect in Safari
4) Verify that the User-Agent is "My Custom User Agent"
5) Reload Without Content Blockers in the Safari View menu
Expected results: User-Agent is My Custom User Agent
Actual results: User-Agent is Safari
Reload With Content Blockers changes the user agent back to My Custom User Agent.
