solved Rated 5 out of 5 stars

Thanks for the quick reply, the culprit was tub utilities, I replaced it with tab mix plus. I havn't tried right click as middle in TU, but I'd imagine it would block the context menu. TMPlus doesn't have any options for right click at all, maybe that's why it plays fine with your add-on.

This review is for a previous version of the add-on (0.3.5.3.1-signed).

I love this add-on, however since some time ago it behaves strange. The context menu appears after 0,5 sec. waiting, but as soon as I release the button the link will open in a new tab anyway and the menu will disappear! If I disable the add-on, links keep opening in new tabs on right click regardless, but there is no context menu at all. FF 11, tab utilities, I have a lot of other add-ons as well.

Disabled add-on should do nothing, so you probably have another add-on with similar functionality.

And try Right Links on empty Firefox profile. If all works – problem is in one of your extensions. So you can disable extensions on by one to detect conflict.

[Upd]
Tab Utilities – Options – Mouse – R-click – On links: Right-click functions as Middle-click
Is it your case?
