Is Vertical Tabs - Tab Manager, Workspaces & Tab Scroll by SuperchargeBrowser safe?

The extension lets webpages trigger a preview that strips frame-blocking headers and frames page-chosen URLs.

On every site, its content script listens for page clicks and can treat synthetic Alt-clicks as a request to open its Glance/Peek modal. That flow asks the background worker to remove X-Frame-Options and Content-Security-Policy from sub-frame responses before loading the selected URL in an iframe, so a webpage can cause another URL to be framed in the current tab.
