Hi, Fred!

Thank you for responding to me. Here are the most recent crash reports that came up:

c43da219-fb5d-4c18-a51a-c1ecec6818a4 04-Nov-16 8:51 PM d8d990bd-3993-41c6-a0b5-80f5f2c93f73 10-Oct-16 6:11 PM 41db838b-a5f4-4271-a9dc-d4308acb0e6a 08-Oct-16 6:10 PM

Unfortunately, that's all that came up for crash reports. I am in safe mode right now, and it is still extremely slow. Like I said, I have tried all the things in those links up above, and it still acts like this. I have tried those links up above, and unfortunately, they didn't help.

Some of your crash reports weren’t sent to the Mozilla Servers.

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it to submit them.

I did do the about:crashes. That's where those numbers came from. I clicked on them, too, and there was no way to submit them. I clicked on them, and they said that they were not found. Like I said, there was no way to submit them, or do anything else with them for that matter. I did have my settings set to submit my crash reports, but I am wondering if that all changed when I kept having to refresh Firefox?

If a line on the about:crashes page doesn't start with "bp-" then click the line to submit the report and the link will be updated and gets a "bp-" prefix if the report is submitted successfully. Please do not add the "bp-" prefix yourself.

Hi, Cor-el

Fred told me to click them, so I went ahead and did that. That's all I have done, that, and copy and paste them for him to see.

Try to submit the reports.

Hi, Fred.

I was able to get those reports submitted once I went into safe mode, but the problem is still there. When I refreshed, I was running without any add-ons at all. I am in safe mode now, and it is still hanging and freezing. It has taken me a few minutes just to type this out. It's not as bad as it was before, but it's still there.

You can try to disable hardware acceleration in Firefox.

• Options/Preferences -> Advanced -> General -> Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

• https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Can you post the crash report IDs that start with a "bp-" prefix since you write that you were able to submit the reports in Safe Mode?

• bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Hi, Cor-El

Here are the reports that I was able to get submitted. Thank you. I am going to try turning off the hardware acceleration and see how that does. I will be right back.

Okay, I have tried turning off hardware acceleration and I have checked to see if any of my drivers needed to be updated. They did not. I have no extensions or themes running at all. I deleted all of them. The only thing left that I haven't done is completely deleting Firefox including the old data and starting from scratch. I wouldn't fight with it so much, but it's the only browser that works with my school.  :-(

Update Malwarebytes. If there is still a problem disable it.

Separate Security Issue: Update your Flash Player Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

Flash Player Version: 24.0.0.186

https://get.adobe.com/flashplayer/ Direct link scans current system and browser Note: Other software is offered in the download. <Windows Only>

https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, Win IE . . . .) Note: Other software is offered in the download. <Windows Only>

See if there are updates for your graphics drivers https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Aha! Thank you! I never thought Malwarebytes would be the problem! I will try and see what I can do on that end. I did update Adobe, and I do see that it is running much better, too. Hopefully, this will solve it.

Thank you so much, Fred and Cor-el, for all the hard work you put in for this.
