is it just 4 me or long click to open tab not working anymore please someone verify... if its not then pls fix it i just love this extension

This review is for a previous version of the add-on (0.3.8.1.1-signed.1-signed). 

Please check following preferences in about:config page:
extensions.rightlinks.enabled
extensions.rightlinks.enabled.left
Both should be "true".
(Or open Add-ons Manager, navigate to Right Links and click on "Options…" button – should be checked "Enabled" and "Options – Enable long left-click")

If still doesn't work, please provide detailed report here https://github.com/Infocatcher/Right_Links/issues
or here http://forums.mozillazine.org/viewtopic.php?f=48&t=645809

Also please try install Right Links on new profile: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
And if it works on new profile, this is probably conflict with other extension or non-standard configuration. And I need information from about:support page.
