This extension does lock a tab and a link that would otherwise open in the same tab opens in a new tab. Nice. But if you refresh the tab, the lock goes away. A more minor event is opening a link from a locked tab makes the lock icon on the tab disappear even though the tab is still locked.
Nevertheless, I will keep it installed as the best we've got so far. Just have to remember to re-lock every time I refresh a locked tab.
I also tried the autolock feature. Does work, but it puts three lock icons on the tab that also disappear as described before. And any opened links from the same domain open locked with three lock icons!
Four stars as this function is so sorely needed, IMO, and am grateful to you for doing what you have done thus far. Any chance for working with the issues I described? Thanks!
