Is 1TabScape: Split tabs into 1 tab, merging all websites. safe?

Low risk

1TabScape removes CSP and X-Frame-Options headers on all HTTP(S) pages it handles.

The extension installs browser network rules by default that remove Content-Security-Policy and X-Frame-Options response headers on main pages and subframes. It also changes Sec-Fetch headers on subframe requests, which can alter how sites and embedded frames are allowed to load or navigate.
