In this section, we will cover some of the most frequently asked questions about our Browser Extensions.

Change the shortcut key for a browser extension.

Our browser extensions come with default shortcut keys:

  • Mac: ⌘ + U

  • Windows and Linux: ALT + U

These can be modified to suit your needs.

How do I assign a shortcut to a Chrome extension?

  • In the top right corner of Google Chrome, click the 3-dot expansion menu

  • Expand the More Tools menu > Extensions

  • On the left menu, click Keyboard Shortcuts (Alternatively, navigate to: chrome://extensions/shortcuts)

  • Scroll to the extension of interest and choose a combination of keys with either “Ctrl” or “Ctrl + Shift” and any available key

How do I add a shortcut to an extension in Firefox?

  • Click the menu button.

  • Click Add-ons and Themes and select Extensions.

  • Click the Tools for all add-ons cogwheel.

    manage extensions

  • Click Manage Extension Shortcuts in the menu.

  • Edit the shortcut options for the extension.

Capture an entire webpage screenshot.

Note: This feature currently works for members only.

With our Capture entire page option, you can capture the entire content of a webpage in a single screenshot. It's useful when you have a long page and want to detail a lot of feedback before submitting it.

  • Click the browser extension.

  • Click the Capture entire page capture button in the lower menu (you can also press the e key on your keyboard)

The entire page capture method might not work on all pages.

  • Color-rich web pages: When creating a screenshot from a color-rich web page, your computer's memory can max out. If that is the case, try to capture a web page with a smaller color palette, hence reducing the screenshot size & weight.

  • Pages with a non-scrollable main<body> : If the main body of your website cannot be scrolled, the entire page capture won't work. If you're the webmaster of the website, fix the HTML by ensuring that the body is scrollable.

  • Unauthorized pages: These kinds of pages do not allow any form of capture, including the entire page capture method.

Capture a screenshot outside of my browser viewport.

Note: This feature currently works for members only.

With Desktop capture, you can capture anything outside of the active tab. It's perfect to draw attention to code in the developer tools or the URL address bar.

  • Click the browser extension

  • Click the Desktop capture button in the lower blue menu (you can also hit the d key on your keyboard)

Update the Browser Extension.

While most browsers update their extension automatically, it may be a good idea to perform a manual update from time to time.

Update Chrome extensions

  • Click the 3 dots

  • More tools > Select "Extensions"

  • Turn on developer mode on the upper left.

  • Select "Update"

Update Firefox extensions

  • Menu button

  • Add-ons and Themes and select Extensions.

  • Click the gear icon. Select Update Add-ons Automatically.

Update Microsoft Edge extensions.

  • Click the three-dotted icon.

  • Select Extensions from the menu.

  • Manage Extensions

  • Toggle the Developer mode button.

  • Click on the Update button.

Remove the widget from my website.

To disable the widget on a website using the browser extension, navigate to your project Settings > Widget > Installation.

Here you can either switch off "Show widget on my website".

I am unable to capture screenshots.

It is not possible to capture screenshots on these types of pages:

  • Blank tabs with no URL (e.g. welcome browser tab)

  • Chrome Web Store webpages

  • Internal browser pages starting with this web address chrome://

Visit another valid URL and try capturing a new screenshot.

If you cannot capture a page type not listed above, ensure that your website allows external iframes to be loaded. If not, update your Content Security Policy to allow to be loaded by following this guide.

What permissions are required?

For the browser extension to work, the extension needs to communicate with the browser API. Therefore, users need to grant some permissions.

Read and change all your data on the websites that you visit.

We need this permission to capture your webpage's content when you trigger the extension and capture a screenshot. We also require that permission to display our capture interface directly inside your website tabs and to retrieve information like the page URL, browser & OS version, etc.

How does it work?

When you load a new page, we inject a script if you want to trigger our extension. We do not interact with the content at this point. We do not read the content. When you capture your screen, the information of the content is not transmitted through our servers yet. Everything remains local. When you submit your feedback, we send it through our servers and forward the information to your connected integrations.

Display notifications

Marker uses notifications to offer you the best experience when working in the background, for example, to keep you informed of the progress of creating feedback.

Communicate with cooperating websites / native applications.

The extension needs to cooperate with our servers on This is the only website we use to collaborate with.

Capture the content of your screen.

Since we introduced the Desktop capture that allows you to capture elements outside of your browser, we need to be able to capture anything that is on your screen.

Capture advanced information.

If you'd like to collect session replay videos, console logs, and network requests, please make sure that you choose to show the widget on the website you want to collect feedback from.

Here we go through a short example using the browser extension with the widget enabled.

Ensure that my team reports feedback to the correct project.

When reporting via our browser extension, ensure reporters select the right project. The extension will always default back to the last project you reported to. A good way around this is to inject the JavaScript widget locally and always use that to report instead. Below, I go through the entire process of how to set that up.

Can I add the extension in incognito mode?

Google Chrome does not permit extensions to run in Incognito mode by default for privacy reasons. However, you can manually enable specific extensions to work in Incognito mode. Here's how to enable the extension to run in Incognito mode:

  1. Install the Extension:

    • If you haven't already, first install the extension from the Chrome Web Store.

  2. Access Extensions Page:

    • Click on the three vertical dots (menu) on the top right corner of your Chrome browser.

    • Hover over "More tools" in the dropdown menu.

    • Click on "Extensions" from the side menu that appears.

  3. Locate the Extension:

    • On the Extensions page, find the extension from the list of installed extensions.

  4. Enable Incognito Mode for the Extension:

    • Below the description of the extension, you'll see a "Details" button. Click on it.

    • Scroll down until you see the "Allow in incognito" option. Toggle the switch to turn it on.

  5. Use in Incognito Mode:

    • Now, when you open a new Incognito window (Ctrl + Shift + N), the extension should be available and active.
