Firefox freezes continuously on Ubuntu 16.04

[Stefano Dall'Agata]

FireFox 62 freezes continuously. (64 bit Ubuntu 16.04.5)
Lock mouse and keyboard on Ubuntu, I have to switch off with the On / Off button. Minor defect, but appeared simultaneously, I open a second / third page, do not load, I go back to the previous one and is no longer loaded, you only see the wheel of time. In this case, restart Firefox.

Stefano,

Thank you for taking the time to report this bug and helping to make Ubuntu better. Do you still see this issue with Firefox 63 which is the currently supported version of Firefox? If so, please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1792329

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

This is a picture of the screen. I had to restart Firefox.

[Olivier Tilloy (osomon)]

Thanks for the additional information Stefano.
It appears you're using a number of extensions. Does the problem occur if you disable all extensions?

[Stefano Dall'Agata (essedia1960)]

When I made the report it happened more often, and I seem to remember (but I'm not sure) that it did it even without extensions.
Now it happens much less.
It happens randomly, but sometimes it blocks the PC.

[Olivier Tilloy (osomon)]

Could it be that your system is running out of memory? Do you have swap configured?

[Paul White (paulw2u)]

Is this still an issue now that Firefox 65.0 is the currently supported version?

[Stefano Dall'Agata (essedia1960)]

Now the PC is no longer blocked, sometimes the pages present the problem of not loading.

[Olivier Tilloy (osomon)]

Stefano, can you elaborate on the exact problem you're seeing now?
Is there a series of steps that can reliably reproduce the problem?

[Stefano Dall'Agata (essedia1960)]

It happens with more than one open card, especially with Facebook.
I have the swap configured, with Ubuntu it can be about 300 Mb in swap.
It seems to me that random happens without apparent similarities between the cases, and since February it has never happened again.

[Olivier Tilloy (osomon)]

Thanks for the feedback Stefano. I'll mark the bug incomplete, which will make it expire in about 60 days. If in the meantime you're seeing the problem again, please comment, and we can re-assess.

[Expired for firefox (Ubuntu) because there has been no activity for 60 days.]
