Set up the browser extension
Set up the uier extension, check Firefox availability, and review a project site without adding the script.
Before you start
The extension reviews only sites your project already includes.
- Chrome or Microsoft Edge 120 or later, on a desktop computer.
- A uier account with access to the project, as a member or an invited reviewer. Ask a project admin to invite you if needed.
- The site’s exact address in the project. An admin adds it in the project’s settings;
https://example.comandhttps://www.example.comare different addresses. - Comments turned on for the project.
Firefox support is awaiting Mozilla review. Public installation is not available yet.
Safari, mobile browsers and anonymous guests use the script and a review link.
Install the extension
Each reviewer installs it in their own browser.
Chrome and Edge
Add uier from the Chrome Web Store. In Edge, allow extensions from other stores when it asks.
Firefox
The Firefox build requires desktop Firefox 153 or later. Once its public release is available, add uier from Firefox Browser Add-ons, then follow the same sign-in and review steps below.
- Add the extension from the store for your browser using the instructions above.
- Pin uier from the browser’s extensions menu, or open it with Alt+Shift+U.
- Open the extension and choose Sign in to uier. Sign in to uier in the window that opens, then confirm.
The extension has its own sign-in, and it stays signed in across browser restarts. Sign out ends it at once and clears the extension’s drafts and active reviews.
Review a site
The review stays on the site you started it on.
Start
Open one of the project’s site addresses, including staging or localhost, and sign in to the site as you normally would. Open the extension: it lists the projects you can access that include this exact address. Choose one when several match, then Start review.
Leave feedback
The toolbar works as it does with the script: pin a comment to an element, selected text or an area, then reply, resolve and reopen threads.
Move around
The review continues on reloads and other pages of the same site in that tab. A link to another domain, subdomain or port ends it, even when that address is in the project.
Finish
Choose Exit review to remove the toolbar. Closing the tab or restarting the browser also ends the review; you stay signed in.
Strict security headers
There is nothing to add to the site’s Content-Security-Policy.
- The toolbar code ships inside the extension, so nothing loads from uier.io into the page.
- Requests to uier.io go through the extension, not through the page.
- Saved screenshots are drawn by the extension, so the page’s image rules do not apply.
- Blocking third-party cookies does not affect it.
Reviews work on pages whose policy blocks scripts, connections, frames, images, fonts and styles. Adding the script instead? The install guide in the uier app lists the sources to allow.
Screenshots
Each new comment takes a screenshot of what is visible in the tab.
The toolbar hides while it captures. The image shows the part of the page the comment is about, or the whole visible page. Content outside the window is not included, so scroll to it first. The comment box says when a screenshot will be attached; choose Omit screenshot to send that comment as text only. If a screenshot cannot be taken, only the text is sent. The author can redact or replace a saved screenshot, and the same image size limits apply as with the script.
Common problems
What the extension shows, and what to do.
No project includes this address
The address must match exactly: http or https, the subdomain and the port. Ask a project admin to add it to the project’s site addresses, or to invite you; admins see Open project setup.
Comments are turned off
A project admin turned comments off. Start review stays unavailable until they turn them back on.
This page cannot be reviewed
Browser pages, extension stores and local files cannot be reviewed. Open the site’s web address instead. Content inside frames from other sites cannot take comments.
The review stopped
You moved to another domain, subdomain or port, restarted the browser, closed the tab or chose Exit review. Choose Start review again.
You were signed out
The extension’s sign-in ends after 30 days without use, a year after you signed in, or when you choose Sign out. Choose Sign in to uier again.
Access was removed
When you leave the project, or an admin removes the site address, the extension stops on its next request. Ask an admin to restore access.
The extension could not connect
Check your connection and choose Try again. If it keeps failing, check the service status.
The site also has the script
While you review with the extension, the site’s own toolbar steps aside, so only one is on the page.
Get help
Email contact@signalco.io with the site address and what the extension showed.
Keep credentials and private feedback out of your message. You can also report a product issue.
Comment links
A shared comment opens once the review starts.
Open the link, then choose Start review: the toolbar opens that thread. Everyone who follows a link to a site without the script needs the extension and access to the project. Guests can use review links only on sites with the script.
