Environment:

OS: macOS (e.g., Sonoma or Ventura)
Browsers tested: Firefox (latest), Chrome (latest)
Vue Devtools version: [7.7.7]
Vue version: [e.g., Vue 3.4.21]
Devtools installation method: Browser extension

Description: When trying to open the Vue Devtools panel using the “Toggle Vue Devtools” button or by selecting a component from the Components dropdown, nothing happens. However, if I open the panel through the browser's Inspect menu and manually switch to Vue, it works as expected.

Expected Behavior: Clicking “Toggle Vue Devtools” or selecting a component should open the Vue Devtools panel and focus on the selected component.

Actual Behavior: Nothing happens on those interactions. No error is shown. The panel does not open or update.

Steps to Reproduce:

Open a Vue 3 project in the browser.
Click on the Vue Devtools browser extension icon.
Try to use:
“Toggle Vue Devtools”
“Select a component” from the component picker dropdown
Observe that the Vue panel does not open or respond.
Right-click the page, click Inspect, and manually open the Vue tab → Works fine.

Additional Notes: The issue is consistent across both Chrome and Firefox on macOS. The project uses Vue 3.4 with Vuetify 3.6.0 No errors in the console related to Vue Devtools.

The cause of this issue was that I had the vite-plugin-vue-devtools package installed inside my project.

When I also had the Vue Devtools browser extensions for Chrome and Firefox installed separately, both the package and the extensions were trying to access the DOM, which seemed to cause a conflict and prevented Devtools from working properly.

Solution: I disabled the Chrome and Firefox extensions so that only the installed @vue/devtools package was active in the project. After doing this, the problem was resolved.
