Why does Shockwave Flash "stop responding" only around 1-3 pm? Works fine mornings and evenings.

Question

For the past couple of weeks I've been having this issue. Everything works fine all morning, and then mid-afternoon, Mozilla goes haywire and I get an "unresponsive plugin" error message, telling me Shockwave Flash "has stopped responding". It derails my entire computer system, everything ends up "not responding" (every single window, tab, program, even pictures and Word documents) then after I spend half an hour moving at the speed of molasses to save, close, and restart things, then it continues working just fine for the rest of the evening. It ONLY happens around 1 to 3 pm.
It's aggravating to say the least. And I can't figure out why. Everything I have from Adobe is up to date, all of my plugins in general are up to date, and I've been using the same exact websites for work for years but this has only cropped up recently.
Any ideas? Should I just take a long lunch and avoid my computer from 1 to 3?
PS: I'm the only person home, and my wifi requires a password, so it's my internet service fighting a crowd or anything.

Answer 1

I'm not paying for Norton for the toolbar, I like the Internet Security options in general.
It has this "Vault" that stores all your website passwords, and "Identity Cards" to store financial information, addresses, etc. I feel safer having this information stored in Norton (which I gave the most unique and secure password I could think of) rather than storing these details on individual websites.
Heaven forbid anyone ever steal my computer, they won't be able to access ANYTHING unless they can hack into Norton, which is the only password I hand-type. Before I got it, I used to have Firefox save it for me, but there was no security in that. Anybody could open up, say, Amazon.com, and log right into my account, and instantly have access to my credit card and change the mailing address. Using Norton Internet Security, they can't get into any of my accounts (shopping, banking, email, etc), and even if they do, they won't find any sensitive info available.
As for Firefox 22, I just clicked "update" the other day (before then canceling) because it specifically said the plugin wasn't available, and I need it for the options I just mentioned. The next time it prompts me, I'll look again and see if it's ready yet.
