It's ahrd to say without more info but if Firestorm isn't responding, the most likely explanation is that your computer is kept busy with something else. If you're on Windows, type ctrl+alt+del or ctrl+shift+esc to open the task manager and see if there are any heavy processes running in the background.

If you have recently installed a new antivirus program, or maybe your AV has just updated itself, see this link for instructions on how to tell it to let Second Life through: https://community.secondlife.com/t5/English-Knowledge-Base/Using-Second-Life-with-a-firewall/ta-p/1304539

If this does not appear to be the problem, check to see if your graphics driver was recently updated.  If so, perhaps reverting to an earlier version will help.
