Yeah i'd like to +1 this issue. Here's the details i've found so far:

The current version i'm using:

Opera Next 24.0 Version: 24.0.1558.51 - Opera is up to date 
Update stream: Next 
System: Mac OS X 10.9.4 64-bit

• Whenever i try to add a link to stash/speed dial etc by hitting the heart icon on the toolbar, it crashes Opera.
• Adding to stash via a context click i.e. ctrl/right clicking works! So it's clearly some toolbar extension related issue ?
• I tried disabling ALL my installed extensions but it still crashes the app.

As per @aeyoun 's suggestion, I tried it also with Opera Stable. But i still face the same issue:

I notice this also with Opera Stable:

Version: 24.0.1558.53 - Opera is up to date 
Update stream: Stable 
System: Mac OS X 10.9.4 64-bit

The odd thing is I actually don't get any crash report or notification. It simply reboots the app, which is why it's a little perplexing.

hey aeyoun, thanks for replying.

Ah, the Mac subforums seems to have this issue logged already. Will continue there. Cheers!

It's almost impossible to use Opera as my primary browser without the bookmarking/stash featuer what gives?
