Most problems with a blocking tool are one of three things: it blocked something it shouldn't have, it won't install, or it isn't doing something you expected it to do. Start with whichever of those it is.
Add the domain in Options → Whitelist. That takes effect immediately and is the fix that's entirely in your hands — reload the page afterwards.
The block page's Report False Positive button notifies your administrator, so it does something on a managed or enrolled device and nothing on a personal one. We'd rather say that than let you press it and assume it was heard.
The install guide covers Chrome and Firefox separately — they
differ in a way that trips people up (Chrome wants the folder, Firefox wants
the manifest.json inside it).
If you loaded it unpacked and it vanished after a restart, that's Chrome's behaviour for unpacked extensions, not a crash. Keep the unzipped folder somewhere permanent — Chrome reloads it from that exact path.
Coverage lists what we actually detect, technique by technique. It's the honest version — if something isn't on that page, we don't claim it.
We deliberately bias towards not blocking when we're unsure. A tool that cries wolf gets switched off, and an extension that's switched off protects nobody.
Open the extension popup and use the account link — it opens the portal in a signed-in tab and pushes a device-scoped token back. Your password never reaches the extension.
If the portal says it can't reach the extension, it's almost always the wrong Chrome profile: link from the profile Nithic is installed in.
Detections are reported; clean browsing is not. Pages we never flag produce no image and no page record, and anything we do store is scoped to your own account — there is no shared pool of what people browsed.
Where a detection does capture the page, you choose what that capture looks like in Options → Cloud & Telemetry: a full screenshot, one pixelated to show layout but not text, or none at all. Worth setting deliberately rather than leaving as found — it is the one setting that decides how much of a flagged page leaves your machine.
