  1. There aren't many... I cleaned house when I reinstalled the browser. Also, this problem occurs even when running FF in safemode. Plugins OpenH264 Video Codec provided by Cisco Systems, Inc. Shockwave Flash 25.0 r0 Widevine Content Decryption Module Add-ons Video DownloadHelper
  2. Nope, same behavior, Firefox hangs on close unless I disable protection.
  3. This is what I get on install from the executable link you provided at https://malwarebytes.box.com/s/1wfy1x2dbjud4bt6i5f97qm8v3wq19rf I can't get past this key prompt without entering a key.
  4. Turning off Exploit Protection definitely fixes the issue. I can reproduce it reliably... EP on... Firefox doesn't terminate, EP off... everything is cool
  5. For the past few weeks I've noticed that Firefox.exe does not terminate upon closing the browser and I've now connected the behavior to Malwarebytes. A bump on effect is that Firefox will not start a new instance until that old instance is killed via task manager. Malwarebytes Running Open Firefox Close Firefox Task manager shows Firefox.exe processor utilization drop to zero, but process is still running New instance of Firefox will start, but will not load UI Malwarebytes Not Running Open Firefox Close Firefox Task manager shows Firefox.exe terminating immediately New instances of Firefox start with no issues Quitting Malwarebytes during the Firefox session will correct the problem as well... bottom line, no Malwarebytes, Firefox terminates correctly. This happens each and every time I close Firefox with Malwarebytes running. Starting Firefox in safe mode does not correct the issue. Uninstall and reinstall of Firefox does not correct the issue. MB logs and MB check results attached. I'm not providing Farbar results. There is way too much sensitive data included, so I hope you can troubleshooot without it. Windows 10 1703 (OS 15063.138) Firefox 52.0.2 (32-bit) Malwarebytes, Component 1.0.103, Update 1.0.1819 logs.zip MB-CheckResult.txt
  6. I'm having this problem as well, but the issue isn't Firefox starting... that's just the side effect. Malwarebytes is preventing Firefox.exe from shutting down completely. With Malwarebytes running, closing Firefox results in the Firefox UI closing, but the Firefox.exe continues to run in the background. If you attempt to restart Firefox, it will not start until you've killed those old processes. Malwarebytes closed, Firefox terminates just fine. I'm running Firefox 52.0.2 (32 bit) and Malwarebytes Premium, Component 1.0.103, Update 1.0.1819 on Windows 10.
