when I double click on Firefox Icon, it doesn't start
when I double click on Firefox icon the clock glass appears on my pointer but the Firefox doesn't start. but some days like today it opens and doesn't have any problem. I predict that I will have this problem again after I close the Firefox's window. The problem started since a few days after updating my Firefox.
This happened
Every time Firefox opened
== afew days after updating my firefox

One of your add-ons might be the culprit. Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If that solves the problem, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and possibly Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
