Lock Tab

Prevents a tab from being closed accidentally

Lock Tab: Chrome extension to Secure your Tabs

"Lock Tab" is a Chrome extension that ensures prevention from accidental tab closures. This extension adds a padlock icon that allows users to switch a tab's state between locked and unlocked. When attempting to close a locked tab, a confirmation dialogue appears to prevent any unintentional tab closure. Please note, after locking a tab some interaction on the page is required for the feature to function as per Google Chrome's mechanism.

finally found a replacement, I used to use Warn Before Close

Two bugs: When I open a new tab, Lock Tab locks it! When I refresh an unlocked tab, Lock Tab locks it! These bugs make the extension close to useless.

Bad. To close chrome I need to confirm closing each individual tab which will prevent chrome from properly picking up where I left off the next time I open it.
