fix: clipboard read request issue in sidepanel by lwin-kyaw · Pull Request #40222 · MetaMask/metamask-extension

lwin-kyaw · 2026-02-19T03:52:31Z

Description

Fixes the "Paste" button being non-functional in Chrome's side panel mode during the "Add New Wallet" → "Import a Wallet" flow.

Root cause: Two Chrome limitations with the Clipboard API in the side panel context:

Permission prompt suppressed: Chrome does not display the web clipboard-read permission prompt inside extension side panels. navigator.permissions.query() returns state: 'prompt', but calling navigator.clipboard.readText() throws "permission denied" without ever showing the prompt. This is a known Chrome behavior with the Async Clipboard API in non-standard document contexts.
Document focus requirement: Chrome's navigator.clipboard.readText() requires document.hasFocus() === true. In the side panel, when the user was last interacting with the main browser view, document.hasFocus() returns false — causing a "NotAllowedError: Document is not focused" error even after clicking the Paste button. Related: crbug.com/1224037, MDN Clipboard.readText() security notes.

Changes:

Detect the side panel environment via getEnvironmentType() === ENVIRONMENT_TYPE_SIDEPANEL.
Request the clipboardRead extension permission explicitly via browser.permissions.request() (from webextension-polyfill) for both Firefox and Chrome side panel — bypassing the broken web Permissions API prompt.
Add a textareaRef to programmatically focus the SRP textarea before calling navigator.clipboard.readText(). Focusing the textarea transfers document focus to the side panel, satisfying Chrome's document.hasFocus() requirement.
Add unit tests covering Firefox and Chrome side panel clipboard permission flows.

Ctrl+V / Cmd+V was unaffected because native keyboard paste goes through the browser's input handling, which doesn't require document.hasFocus() or the web permission prompt.

Changelog

CHANGELOG entry: Fixed the "Paste" button not working in Chrome side panel mode during wallet import

Related issues

Fixes: #40213

Manual testing steps

Open the MetaMask extension in Chrome Side Panel mode
Navigate to account list → "Add Wallet" → "Import a Wallet"
Copy a valid SRP to your system clipboard
While viewing another site in the main browser view (so the side panel does not have focus), click the "Paste" button
Verify the SRP is pasted into the textarea
Repeat step 4 after clicking inside the side panel first — verify it also works
Open MetaMask as a popup and repeat steps 2–5 — verify existing clipboard behavior is unchanged
Open MetaMask in Firefox and repeat steps 2–5 — verify Firefox clipboard behavior is unchanged

Screenshots/Recordings

Before

After

Clicking the Paste button in the side panel correctly pastes the SRP from the clipboard.

I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Medium Risk
Touches clipboard-permission and focus behavior during wallet import; mistakes could break paste UX across environments, though the change is localized and covered by new tests.

Overview
Fixes the SRP import “Paste” button in Chrome side panel by treating side panel like Firefox: explicitly requesting clipboardRead via browser.permissions.request() and focusing the SRP textarea (plus window.focus()) before calling navigator.clipboard.readText().

Refactors the paste path into requestPermissionAndReadClipboard(), adds error handling around clipboard reads, and extends unit tests to mock webextension-polyfill/getEnvironmentType() and cover both Firefox and side panel behaviors (including textarea focusing).
