That prompt is the guidance for the Description field — it wants "what it does + why install." Here's a version tuned exactly for that (leads with what it does, then a clear "why install"), still honest and non-salesy:
SnapHAR captures a browser tab's network activity and saves it as a standard HAR 1.2 file — without opening DevTools.
Getting a HAR today is a fiddly dance: open DevTools, find the Network tab, turn on Preserve log, reproduce the problem, right-click, export. SnapHAR replaces all of that with two clicks. Open the popup, click Start Recording, reproduce the issue, then Stop & Export. A valid .har lands in your Downloads — ready to re-import into the DevTools Network tab, attach to a bug report, or send to support.
Why install it:
• Faster — one click instead of the manual DevTools flow.
• Reliable — recording keeps running across reloads and redirects, so you never lose the request you were chasing.
