Firefox tab crashes at startup

more options

I am on Linux, the kernel version is 3.10.0-663.el7.x86_64 (Red Hat 7.4 beta). I am working through ThinLinc version 4.8.0, Build 5456. When I start Firefox I get a tab indicating a crash. When I am logged directly on the machine, not through ThinLinc, it work fine. I copy the error message I get in my shell from the crash:

See:


You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.

  • browser.tabs.remote.autostart = false
  • browser.tabs.remote.autostart.2 = false

You can open the about:config page: via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
