I gave up on delicious a long time ago, after it has changed hands several times and the code-base had reverted to a steaming pile of pre-web-2.0 shit. The browser extensions has all mostly died a long time before, and mobile apps were non existent. I tried every replacement, but nothing was quite like delicious was in the glory days.

Then raindrop.io appeared. It's another one-dev project, but it's like a polished delicious, has working browser extensions, and even it's own mobile app. Worth a look, no affiliation. (Now if only I could figure out whether it's created by the GRU cyber division to gather intelligence )
