Questions[crash](ubuntu)

I have an Ubuntu 18.10 dual boot with Windows 10. I think that because of the error below my Ubuntu crashes/hangs a lot lately at the time of reboot/startup.

I am running Ubuntu 16.04 and Firefox freezes my system about once a day. I know it is Firefox because my system works fine with Chrome. The same freezes occurred when running Firefox from live USB versions of Ubuntu 16.04 and 17.10. When frozen, the keyboard and mouse are unresponsive, and various Ctrl+Alt+ and Alt+SysRq+ combinations (commands on this page for example) don't seem to do anything. I end up having to hard reboot by holding the power button.

I am not a Linux expert, but my understanding is that at this point I should check /var/log/syslog, /var/log/kern.log, and similar files. I have checked the contents of these files, have web-searched the messages, but don't know enough to have any meaningful insights. So what should I do next?

If it helps, below is the end of my /var/log/syslog prior to the crash. And I would be happy to update my post with any more info.

update 1 (May 21 2018)

I am still getting freezes when I run Firefox from a terminal in safe mode with my profile path set to an empty directory (a step suggested by @dsstorefile1):

firefox -safe-mode -profile ~/some_empty_directory/ -no-remote -new-instance

I also ran debsums to check the checksums of the Firefox package, but it did not find any errors.

update 2

I installed Arch Linux on my machine and still got the same behavior. This means it is not a distribution-specific problem.

update 3

I upgraded by RAM, graphics card, and monitor. But the problem is still occurring.

update 4

I updated my BIOS, but the problem is still occurring.

After fresh Ubuntu 18.04 installation and afterwards a netbeans installation, netbeans does not start. netbeans was installed with

sudo apt install netbeans

some other java programms (at least Eclipse) do not start too.

when starting netbeans from commandline the JVM prints folowing WARNINGS:

➜  ~ netbeans
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.netbeans.ProxyURLStreamHandlerFactory (file:/usr/share/netbeans/platform18/lib/boot.jar) to field java.net.URL.handler

WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations

An app just crashed and I want to copy the error message and paste it into a search engine to hopefully find a solution.

Unfortunately the error dialog does not allow me to copy/paste anything:

In particular the stack trace, which is very long. Typing manually is slow and unreliable.

Maybe the same details can be copied from somewhere else?

Note: Similar to How can I copy the text of an unreportable error? but with more details. If one must be closed as a duplicate, despite being newer I believe this one is more useful. It is de-facto more popular: 200 views there, 42k views here.

I recently downloaded the Google Earth .deb file for 64-bit from here. And I installed it with:

sudo dpkg -i google-earth-stable_current_amd64.deb

And I of course also installed all of the other necessary dependencies with:

sudo apt-get install -f

Which Google Earth depends on. But now when I start Google Earth with:

google-earth

It launches, stays open for about 10 seconds, and then exits. From opening it to it closing this is what I see in Terminal:

Another crash happened while handling crash!

I am not sure of the meaning of these error messages, and what I should do about them to stop it from only lasting 10 seconds. So is there anyway I can fix this? Or is this some sort of bug? If so, where should I report it?
