Since most volunteers here are not familiar with the unique issues involved with nightly builds, I wonder whether you might get more relevant feedback on the mailing list: https://mail.mozilla.org/listinfo/nightly-testers

You do show one extension that isn't a default. {d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d} 2.6.9.1-signed Be nice to know what that is. Plus info about you graphics drivers would be nice to see.

{d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d}.xpi loads in Mozilla Firefox as a compliled extension named 'Adblock Plus'

Does it help if you disable e10s in about:preferences > General?

Experimental Features

I performed a System Check and found that there are in fact corrupted files, but Windows can't fix them. I tried to view the log of the files checked to find the corrupted ones, but when I put in the command the Microsoft website advises, nothing happened. The command is findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

...which I found here: https://support.microsoft.com/en-us/kb/929833#CBS%20log

Scratch that, I figured out what files are corrupted: the utc.app.json files. A bit of googling tells me that this is a non-issue, but it sounds like there should only be two of them, and I have four (three of which are the same size, one of which is substantially larger). Is this a potential cause of this problem? Should I delete the one that's bigger?

It's better to remove that full program, then reinstall the current.

Which program do you mean? Firefox?

The crashes are shutdown crashes in accessibility (a11y)

The System Details list shows that Firefox thinks that accessibility is active.

Accessibility: Activated: true

Is e10s activated?

Do you have a pref like this?

• browser.tabs.remote.autostart.disabled-because-using-a11y

The command is findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.

Open your file browser, and type %WinDir%\Logs\CBS\<enter>. Find the CBS.log file. Open it in a test editor. Click once in the file, then press <Control> A to highlight everything. Then <Control> C to copy it. Now go to the reply box below, and Paste it in.

Yes, e10s was enabled. Oddly enough, I haven't had any crashes since I disabled it.
