Chrome Close Lock Extension

This extension opens a tab that can't be closed without your permission.

This prevents you from accidentally closing a multi-tab browsing session.

!!! NEW FEATURE - THEMES !!!
Clicking the icon opens the options page to choose theme options.
Send your theme ideas via email.

Click the red button on the Chrome Close Lock start page to enable protection.

Chrome version 88 or higher is required.

Popup bug has been fixed in rev 3.
Incognitio window bug has been fixed in rev 5.
*NEW FEATURE* Activate by pressing a key added in rev 6.
May 20, 2023 update was an update of internal manifest file which accidentally broke the extension (SORRY).
Minor changes in rev 7 for compatibility with manifest v3.

NOTE: Chrome Close Lock protection is no longer automatically activated. Newer versions of Chrome now require you to interact with the page to activate the code that makes Chrome Close Lock work. We added the enable button for this purpose. We are actively working to make it fully automatic again.

̇ (ID: 000000471e9f3da2) Voted 4 ★ - Updated 05/22/2024 it works as it should be, saved me from accidentally closing Chrome with tons of tabs, except for the themes and visual it absolutely needs a better alternative.

gen den (・_・) (ID: 0000004acb7d82d4) Voted 3 ★ - Updated 03/04/2024 working. but bad visual.

Zieneth Starr (ID: 000000b998cdd55e) Voted 5 ★ - Updated 10/27/2023 Works so far. I haven't had the multiple pages open like others have reported.

Brialynn M (ID: 000000a225e4b7c7) Voted 1 ★ - Updated 10/13/2023 Would've been a wonderful app and it does what it says it does but it keeps opening like a billion tabs and glitching every so often out of nowhere. Like, even if I'm not interacting with the window, it'll just spasm out of nowhere then lock up my chrome so I can't use it.

Sun Li (ID: 000000b12c8b18dd) Voted 3 ★ - Updated 10/04/2023 Used to be great. Past few months, it occasionally (once every 2 weeks) glitches and opens a few dozen times in the same Chrome browser window, lagging the browser to the point of freezing. 5 minutes later it crashes the extension and I have access to my tabs again.
