How To Restart Chrome or any Chromium-Based Browsers Without Losing Open Tabs
If you Copy-Paste chrome://restart in the browser’s address bar, it will instantly restart your browser without losing running tabs or windows.
But the fastest way to restart the browser with a single click is to use the internal command as well as the bookmark bar.
1. Right-click on the Bookmarks bar and select “Add page…” from the drop-down menu and select the Bookmarks Bar as the folder to save your button in.
2. After you select “Bookmarks Bar” in the menu, give any name for the bookmark and type chrome://restart in the URL field.
Click on the “Save” button to create the bookmark.
3. Now you just have to click the bookmark to restart your browser.
Toggle Ctrl+Shift+o (on Windows and Linux) or ⌘ + Option + B (on Mac) to make the Bookmark bar visible; then find the currently-created bookmark by name, and then just drag and drop it into the Bookmark bar.
