Unresponsive scripts still, even in safe mode!

Question

Hello,
I have been having the Unresponsive Script warnings for what is probably going on a year or so now, and it's getting increasingly difficult to use my computer. I'm not hugely technical with my computer, but I do know some, and have fixed many many problems before, even fixing my computer from a devestating malware virus a couple years ago myself, using only information from the internet.
Which is why I find it so infuriating that I cannot find ANY answer to help me with this problem.
Here is some of what I get in a day or so:

Most of the time it's Facebook that's giving me a problem, but it does it on other websites too. Without going into tons and tons of detail, I have basically tried EVERYTHING I can do on my own. I have searched this problem for months and months, and always come back with nothing helpful.
I tried FF safemode in the past day or two, and it occurs there as well. I have tried everything from changing dom.max_script_run_time default, I've tried Greasemonkey, I've disabled, enabled, and disabled every script I had, I've reset FF, I've turned off the hardware accelerator, etc, etc, etc. I can't even tell you everything else that I've done because it's been such an ongoing problem. I am to the point now, that I am not going on the computer for days (even though I have things to do) because I don't want to be on it for 6 hours at a time. I want to check facebook every day for about 30 minutes, to read my mail, and chat with my friends, but it turns out to be a lesson in frustration, and I've learned to play classical music when on my computer because it calms me down. Waiting 3 hours just to check your facebook is increadibly inconvenient; something that I did at the library in 10 minutes. It doesn't just happen on FB, but that's the MAIN culprit. My Shockwave Flash also crashes ALL the time, and I've updated it several times. I've tried everything, and I just can't win. If this continues, I'm giving up on FF. I love FF. I want to use it. It used to be the best thing ever. But now, I can't do it anymore.. my patience is so stretched, that I am just done.
I am OBVIOUSLY not the only one with this problem, as there seems to be a million questions on the internet about this problem, and NOBODY can give a straight answer.
WHY?? FF you can do better than this! You MUST solve this problem! It's affecting so many people out there!
Sincerely, M
Ps.. I have a PC, Windows XPPro, FF22.0, and I had YesScript 1.9, Personas Plus 1.7,2.1, and Status-4-Evar 2013.02.16.23 (But all have been removed with the FF Reset) and none of them were the culprit because I disabled them a while ago, and still had the problem day after day.
Thank you for your help :)

Answer 1

NONE of the above has worked for me. Currently running FF 23 and Windows 7. What I'm experiencing strictly happens with the Facebook news feed, and may be completely independent of Firefox as others have reported this problem in other browsers...(https://www.facebook.com/help/community/question/?id=10151551364085966&referer=answered_notification&ref=notif&notif_t=answers_answered)
