tabs are still closing with no reminder at all.
Funciona perfeitamente para o que eu queria! Abro muitas janelas de programas como excel etc, e ao fechar algumas as vezes clica duas vezes ou clica fora perdendo importantes janelas abertas que não da pra recuperar como dados de formularios.
Very nice and useful, but its implementation is strange and it needs to be hidden like other extensions . It better be active all time and hidden . Thanks
extensão é simples e boa, ajuda pq o chrome não tem essa função como o mozilla
Doesn't work the way I had hoped, offering a warning when the window is closed, not the tab - so basically it won't stop you closing any website unless there are no other tabs open in that window. I was hoping for something that automatically engages on specific websites, not something that needs to be turned on manually every time. Having to have a weird extra tab open to operate the app is clunky to say the least, and the visual design of the app is ugly and excessive.
I can see no reason at all why you need to Read browsing history Manage apps, extensions, and themes These are the sort of activity used by hackers. Well, not on my computer. I've been using the app for a while now, it WAS brilliant. Now, it is disabled and going to be uninstalled.
Very helpful extension. But I enjoyed the kitten pictures. If embedding the pictures increased the size too much, how about adding an option to display the user's own pictures from a particular directory?
Hello dev, could you please bring back the option to enable locking each window by default? In the new version, I would have to manually activate the close window protection feature. I miss the days when all new browser windows are automatically protected the moment they're first created. I'm a lazy set-and-forget kind of person😂 I'm used to the days when the pinned protection tab doesn't kick in, I can click the extension button to lauch the dedicated pinned tab and thus activating protection feature. Edit: found one of your earlier reply to another reviewer. Sorry for the misunderstanding, it seems that Google has made the auto-enable impossible in newer Chrome versions.
A solution that helps prevent me from accidentally closing Chrome. I do agree with the other reviews that the visuals are very weird. Please make a basic theme that is just a blank page. There's no need for themes.
Perhaps if I had kept this installed for more than 30 seconds, I'd have gotten used to a weird permanent tab with a monster face on it. Please someone implement this functionality in a straightforward day.
