Start Firefox in Safe Mode
While you are in safe mode;
Firefox Options > Advanced > General.
Look for and turn off Use Hardware Acceleration. Then restart.

Thank you for replying but I had already tried that out of safe mode and i just tried it again in safe mode. Nothing changes. Last night I finally just started it in safe mode and hit the "reset" button, still does nothing. I may just go install firefox 29.01 from mozilla website and start over since updating my existing version (though it has always worked) isn't working with this version. sigh. Also when you say "then restart" do you just mean close firefox and open it again bc there is no restart button? I guess tons of people are having this issue. I was thinking maybe I would try and get firefox 29.0 bc i never was asked to update to that. But i see it has security issues, so idk. Off to get a "fresh copy" I guess as they call it , right? Maybe other ppl will have a suggestion or have figured out a way to solve it. I spent a number of hours repeatedly trying to get FF to work. It's frustrating. At least I have Chrome to use right now

- Try uninstalling FF > Remove my Firefox personal data and customizations

- Try Portable Firefox : http://portableapps.com/apps/internet/firefox_portable

Okay, so I can happily say that I am typing this on firefox yay!! I got it to work and here is how for everyone else who's having this problem (well at least this is the solution that finally worked for me). RESTART your computer. DO NOT just shut it down. That does not work (not for me at least). I initially restarted the computer a few min ago b/c my Norton was not scanning and I wanted it to scan the new "fresh install" i had gotten for FF. After restarting computer, my norton worked. So i said hey, maybe I'll give my updated FF 29.0.1 one last try before installing a whole new firefox, hoping that possibly restarting the computer would have worked. So i opened it and omg it loaded my homepage. It works!!! Also, one of the other first problems I encountered is no way to favorite a site. I figured out the solution. Just go to the right top menu (it has 3 horizontal lines) and right click the little star icon that we are accustomed to which means bookmarks. A little menu will pop up. Click "move to toolbar," and that should put it up on the top right of your browser so you can bookmark things. Hope the restart tip helps everyone who was having the same problem as I was of firefox being unusable! And if you run into the bookmark issue, hope it helps you also. Wow. I'm so happy I can finally use FF now! Also, I kept the setting of "no hardware acceleration off." Not sure precisely what that does, but leaving it off since this is working. Oh, one last thing: I closed FF and ran cc cleaner and had NO problems with it telling me FF wouldn't close. So restarting the computer has solved that as well. Yay!

Good going. Every now and then, you should let the computer shut down. I don't mean every hour but every few days. This lets the system take care of things it can't do while it is running. And if there was a problem, restarting should restore / reset the program.

Thank you Fred, I am pleased I can now use FF.  :) Should I still keep that "accelerate hardware" option off? Idk what that does.

From the Firefox help files;

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

I am also missing toolbars. The Navigation Bar is gone. And it takes forever for FF to load. I used to be abler to have several tabs open.no more. I have done system restore, restarted my computer. What do I do, please?

• For the toolbars;
  
  

Move your mouse to the top of the Firefox window, then right click. You will see a menu of the available toolbars. Select Customize. In the new window, you can choose what options you want and even move the icons around. It's very simple. Look for the icon. When you find it, hold down the left button on it, and move it to where you want it to be. You can move any of the icons you want from here, but some icons are locked in place.

It could be the work of one of your add-ons, or even add / mal-ware. Look thru your add-ons list and make sure you know what each one is there for. Also, Windows > Start > Control Panel > Uninstall Programs. Go thru the list and use a web search to check any that you don't know what they are.

Thanks for your help. I did that with the icons; had been doing it wrong. But since the update the background of the toolbars is gray; and there are several I can barely see.

Take a Screen shot; Windows > Start > search box > Snipping Tool. Save the picture(s) to your desktop. Now look at the Reply box below. Do you see the button under it that says Browse? Click it and then select the screen shot(s) from the desktop.

This is a part of the toolbars where I added. You can barely see the printer. Thanks for all your help. I do appreciate it,

Somebody get me a flash light, I can't see a thing. :->

Go to the Mozilla Add-ons Web Page (There’s a lot of good stuff here).
Search for something that can change your window color.

While you are at the Mozilla Add-ons Web Page check out Featured Themes

Hi Fred, You have been so helpful. I did go to the add on page and am overwhelmed. All I want is the toolbars to be readable. Any thoughts as to which one? Thank you so much for all your help.

That you will have to do on your own, About the Featured Themes, if you place your mouse on top of one of them, the browser will change so that you can see what it looks like. It is not downloaded, only displayed.

Hi Fred, Most of them were too dark and complicated, but I did find one on the new link you provided. Thank you sooooo much~

FF 29.0.1 was hanging on load for me in W7 64-bit. I ran the "compatibility checker" which advised running it in XP SP2 mode. After that, no problems, it runs fast and fine.

@ fredmcd, you stated "Shut your system down every couple of days, this lets the system take care of things it can't do while it is running."

seriously fred... I do believe you've clicked your ruby slippers together 1 too many times. If the computer isn't running... it can't do anything. I don't care what Auntie Emm told you, if the computer isn't running it does not have the capability to perform one single task. Period. Don't believe me ¿ ASK TOTO.
