This is a very common issue to Mozilla Firefox user, this might not be noticeable unless you right on links to open it in a new tab. The main issue here is that the latest version of Mozilla Firefox which is 3.5 is a buggy thing as some other user may call it. This is due to incompatible add-ons.
The Solution
Solution to this is quite simple. Before anything make use of the firefox safe mode which can be found in windows program list in your start menu. Now Try to search for anything else and right click on a link to verify if right click is enabled with safe mode. The next procedure is to run firefox that is currently installed in your desktop. Now click (Tools > Add-ons) and if you see yahoo toolbar that is currently installed then disable that add-on or you may want to uninstall it. After uninstalling the add-on it will ask you to restart the browser.
Now try to check if right click is enabled already because most of the time yahoo toolbar is the main cause for this issue. Still not working? Then the best thing to do now is to disable all add-ons that is currently installed and enable it back one at a time so you may know which add-on is causing the problem.
This is all that I can share as of this moment. If you have any other fixes or solution to this issue feel free to post it here…
