Doesn't work with Vivaldi (at least my version. Other Chrome extensions do. Great idea though. No idea why "close confirm" isn't an option on every browser, it's pretty basic.
People are fool who are giving bad reviews, I accept that this is not a perfect extension, but you don't have any other choice if you don't want to accidentally close your chrome(especially in incognito mode), I find it very useful!
Trust the bad reviews - this is not what you think. Immediately uninstalled this intrusive, obstinate plugin.
Annoying. Tab suddenly pops up out of nowhere and i've actually closed chrome accidentally more with this plugin than before haha.
Good extension, it should work automatically though. Another thing, please change or allow to change the tab icon, it is simply annoying (i mean the warning triangle that changes color [warnBlk, warnBlu, warnRed, warnWht]) it should be something simpler (no animation imho) like the disabled lock icon (brown).
Ogni volta che riapro il computer (di solito lo lascio in stand-by) devo riattivare chrome close lock, mi sono scordata di farlo, ho chiuso per errore una ventina di schede, ho cercato di riaprirle dalla cronologia -> chiuse di recente, ma secondo chrome le schede chiuse di recente erano venti schede chrome close lock. No, capiamoci, è più confusionario e dannoso che utile.
Need you click to confirm,its not a automated work!!!how can be enabled on startup???

Not quite what I'd hoped for, but ok. What would really be useful would be to be able to lock specific tabs (like making sure I keep my gmail tab open) rather than having just a generic lock on the whole browser session. I tried putting my gmail url into the locked tab, and now I have another tab next to the lock that seems to open automatically and only has the gmail icon, no text (similar to the locking tab) so ... well, I guess that's OK, even though it's probably not supposed to be used that way. I would love to be able to lock gmail, Trello, and other things that I need to keep up on, and also to be able to temporarily lock sets of tabs when working on a specific project. That seems like it would be a fairly common use case, I wonder why there aren't browser extensions that do that?
Thank you
