It sounds like the Computers CPU is being overworked.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

While still in Safe Mode,

This link has a program that can crash Firefox.

Thank you for the quick response. I followed your instructions and I show 3 Crashes WITH the BP in front of them… Under the headline Submitted Crash Reports. There are none in Unsubmitted…

Your instructions tell me to click on them if they Don’t have the BP. So what do I do next since they do? I will await next steps I should take, as I’m not sure where to go from this point.

YES, I HAD SAME ISSUES IN SAFE MODE I was on Firefox in Safe Mode for about a 45 minutes and was issue free when it occurred again: • as I clicked to open a new tab to navigate to the support site to post the crash report in the reply box for you • Then again in clicking on the Support link in the Mozilla.org/Firefox page • in selecting the categories of support • clicking on the Sign in link • Clicking the Log In button • Again clicking the link & page to this question on the “My Questions” result page • Clicking in the reply box • And while typing this in received BUSY SERVER ERROR

All appear to be related to clicking on links….   But up to that point, there were no issues.  I should point out that when the screen turns white, afterwards it takes a while for the system to allow me to click on or insert a spot for text (i.e. logging in)

If the program runs fine in Safe Mode, it points the finger towards something that loads when not in Safe Mode Not sure what all is disabled in Safe Mode. However, I can tell the only add-on I use, Tabs Mix Plus, is disabled. (I figured add-ons would be)

Also, you mentioned that my issue sounded like the CPU was being overworked. I’m wondering how that could be, if the issue occurs after a system reboot and not opening anything other than Firefox, and maybe Outlook? I have most all non-essential programs omitted from firing up at start up. I’ve never had the issues I mentioned starting Firefox as so many help topics referred to, only after being in it for a while

Please consider turning on send info to Mozilla before posting a question. This helps us help you. As I have no info from your system that would help see things that cause issues. Info sent would have include stuff on your Video Card that possible would have led to being resolved before this time.

EXCEPTION_BREAKPOINT is the crash name and it mostly associated with Video Card Drivers. In the crash report drivers are noted as the issue. https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration ALSO TRY NO HARDWARE ACCELERATION There maybe newer ones or they may have got corrupted so update or reinstall them please.

If the server issue was today then it might have been the North American outage https://www.product-reviews.net/down/level3-internet-outage-status/ plus Comcast/Outlook small list included.

When you uninstalled and reinstalled did you delete the Mozilla Firefox folders in c:\Program Files and c:\Program Files(x86) ??? Did you install from the tiny Stub installer or the Full Version 56.0.2 Installer , https://www.mozilla.org/firefox/all/  ???

That was very good. These reports may tell us what's going on.

Fred McD, So, what do you advise me to do? The reply I received in between both of yours, was saying to update or reinstall my Video Card driver, which is up to date...also asked if I reinstalled the full version of Firefox, and gave me a link to it, in which I was able to download but haven't had a chance to do anything yet. You mentioned that the provided reports may point to the issue. How will I know if they do? Because, I can't decipher the lingo in the above.... Are you able to see and let me know, or will I receive some communication as to how I should proceed?

Working in Safe mode now without any issues so far. Not experiencing any slowness, and able to scroll my pages instead of them freezing for 10-15 sec... which is the indicator that it's periodically not responding.

I await your direction. Thanks, I apreciate your assistance.

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

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

In Firefox 54 and below:

1. Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
2. Select the Advanced panel and the General tab.
3. Uncheck Use hardware acceleration when available.
4. Close Firefox completely and then restart Firefox to see if the problem persists.

In Firefox 55 and above:

1. Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
2. Select the General panel.
3. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

   

4. Uncheck Use hardware acceleration when available.
5. Close Firefox completely and then restart Firefox to see if the problem persists.

Did this fix your problems? Please report back to us!

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Thank you.

Fred McD, I already unchecked the Hardware Acceleration box prior to my initial question. So, that didn't help. It is still unchecked.

On in Safe Mode without any issues for almost 2 hrs, for what it's worth to note.

It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

Fred McD., Well, as mentioned before. I only have 1 pug in, Tabs Mix Plus. Which I disabled. Things went fine for a long while then back to same issues of Not Responding when clicking the title bar or opened tabs. I don't have an Antivirus, as I was suggested against it, since Defender would do the job and best not to have conflicting programs.

Windows did another version update before I disabled Tabs Mix Plus..

I think, I may wait for the new Nov 14th Firefox release and reinstall with that version.

Any other suggestions?

On my Win 7, I use Microsoft Security Essentials and Norton 360. Never had a conflict.

Fred McD, Thank you! You were great in all your persistent assistance and follow ups to my issues on this site.

After trying everything, that I located on this site and from your suggestions I was able to minimize my issues. Which were: • Firefox becoming “Not Responding” errors in title bar o Causing screen freezing, delayed text inputting • Busy Server error messages • Script error messages • Crashing

I mentioned I’d get back to you after I had downloaded the NEW FULL version of Firefox with my results.

After waiting 24 hours after installing the new Firefox, I’ve had NO ISSUES. Firefox is working as expected. My issue is FIXED!

For those that want to know what I did in Windows 10, I’ll share, as there are many solutions out there. This worked for me, and took approx. 15 minutes or so: • Completely uninstalled Firefox and reinstalled the new FULL version. • To do that, here are the steps: 1. Download the new FULL version of Firefox at this address: , https://www.mozilla.org/firefox/all/ 2. Back up your Bookmarks – google the directions 3. Delete Firefox: Start>Settings>System>Apps & Features>Click on Firefox>Uninstall 4. Delete Firefox Program Files: in C:/ Program Files & C:/Program Files(x86) if they are there after the unistall, if not, move on. 5. Delete Firefox Program files in C:/Users/your name/Appdata in each folder (Choose Local, LocalLow, & Roaming 6. Then clean Firefox Registry files:  Windows Key+R > Type in regedit  Click yes to make changes  Choose HKEY_Current_user>Software>Mozilla & Delete  Choose HKEY_local_machine>Software>Mozilla & Delete & Mozilla.org & delete 7. Restart computer 8. Run a registry Cleaner (CCleaner free version on Cnet.com works fine) 9. Restart computer 10. Install the new FULL version of Firefox > Import your bookmarks > Reset your Options > You’re Good to Go! 11. BTW: The new Firefox Bookmarks are a bit different. If you want to fix it so your bookmarks, etc open in a separate Tab, go to this link for the 3 minute fix without needing a Add-On … http://techdows.com/2017/09/firefox-57-open-bookmarks-in-a-new-tab-preference.html#comment-141526

That was very good work. Well done.
