About Plexar Browser Bridge
Plexar Browser Bridge lets the Plexar Harness agent work in your own Chrome or Edge browser, with the sites you're already signed in to, instead of only in a separate browser window.
How it works:
• Each Plexar Harness project gets its own colored tab group, named after the project (for example "Plexar · my-project"). The agent works only in the tabs of that group; your other tabs are not shared unless you drag one into the group.
• While the agent controls a tab, Chrome shows a bar across the top saying the browser is being debugged, so you always know.
• When Plexar Harness finishes or closes, the tabs the agent opened close too. Tabs you dragged in stay open.
• The extension talks only to the Plexar Harness app running on your own computer (127.0.0.1). It has no server of its own.
• Turn it off any time in Plexar Harness under Settings > Features > "Use my Chrome", or remove the extension.
