hello Vikram-Kumar, please try the following: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named plugin.blocklisted.flash & plugin.blocklisted.java - right-click and reset those entries to their default value.

Thanks Philipp but i have already done that and the content started working... However, when i closed and restarted the browser it returned back to the same settings... I dont think that should happen, but anyway thank you for the solution. At least I can use it by resetting the values if need be Appreciate your help
