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

Signature: IPCError-browser | ShutDownKill

Attention Sumo's there are 35 related bug reports

ShutDownKill means that something within Firefox is not responding.

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?

Hi,

in safe mode is no issue because the Adobe Flash Player isn't loaded.

Not correct. Flash is a plugin and not affected by Safe Mode.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

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.

Like I wrote hardware acceleration is disabled. Adobe Flashplayer plugin 30 is installed on the server but it is not shown in the firefox extensions.

In the Add-ons Manager, select Plugins. Make sure it is Always Active.

In Safe-Mode Firefox is not recognizing the plugins. I also disabled Hardware Acceleration again.

Could you please try to help me with my problem?

The point is when browse with firefox to a website with a flashplayer, firefox is freezing and after that the flashplayer isn't loaded.

HI, try this, uninstall Flash using this tool :

• https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html

Now uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

• https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
• https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer

Reinstall with Current Release Firefox 61.0.1 with a Full Version Installer

• https://www.mozilla.org/firefox/all/

Now reinstall Flash :

• https://get.adobe.com/flashplayer/otherversions/

Please let us know if this solved your issue or if need further assistance.

I tried it, but I can still reproduce the issue in a remote desktop.

Regards Achim

Try some windows cleanup, defrag, use MS Disk Cleaner and also from a DOS Prompt as Administrator Copy/Paste sfc /scannow and Enter, Reboot after. ( sfc<space>/scannow )

Profile : Make a new one and test ...:

If is your Profile :

• https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile
• http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

To make this clear Firefox is installed on a VM guest Windows Server 2012 R2. In the vsphere console, the firefox and flashplayer are working. When we connect to the VM via remote desktop, it won't work.

We already disabled hw acceleration.
