CopyThat

A tabbed notepad for storing and copying text snippets. Organize your notes into color-coded tabs, copy any tab's contents to the clipboard with one click, and paste wherever you need it.

Features & Capabilities

CopyThat is a notepad that lives in your browser toolbar, built for the text you paste over and over: canned replies, code snippets, form boilerplate, addresses, meeting links. Instead of digging through a document or switching to a notes app in another window, your snippet is two clicks away from any page — open the popup, hit copy.

WHAT IT DOES

• Tabbed notes — up to 20 tabs, each with its own title and room for 25,000 characters. • One-click copy — the copy button puts the active tab's entire contents on your clipboard. • Color coding — assign any tab a color from a nine-swatch picker, or let it fall back to the automatic palette rotation. • Inline rename — double-click a tab to rename it in place. Enter commits, Escape cancels. • Drag and drop to reorder tabs in the sidebar. • Bulk delete — an edit mode with checkboxes and select-all, with a confirmation step so nothing disappears by accident. • Keyboard navigation — arrow keys move between tabs when the editor isn't focused. • Live metadata — character count against the limit, tab count, and how long ago each note was edited.

PRIVACY

CopyThat keeps your notes on your machine and does nothing else with them. It makes no network requests of any kind, injects nothing into web pages, and holds no host permissions — it cannot read or modify any site you visit. There is no account, no sign-in and no cloud sync, so your notes are never uploaded to anyone's servers and no identifier ties them to you.

It requests exactly two permissions: storage, to save your notes, and clipboardWrite, which Firefox requires in order to place text on the clipboard. It does not request clipboardRead, so it can write to your clipboard but can never inspect what is already on it.

The extension is plain JavaScript with no third-party runtime dependencies, and it only runs while the popup is open.

GOOD TO KNOW

Notes are stored unencrypted in your browser profile, so anyone with access to your computer account can read them. CopyThat is a notepad, not a password manager — please don't keep passwords, API keys or tokens in it.

Because notes are stored locally and never synced, they stay on the device where you wrote them and are not backed up anywhere.

Is CopyThat Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

CopyThat requires very minimum permissions.

Risk impact analysis details
  • High Allows reading and modifying clipboard content, which can be sensitive, posing a moderate privacy risk.
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

CopyThat is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
