̇ (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.

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.
