Hi Moses, hardware acceleration is already disabled. I have had a few crashes since disabling it.

How much RAM do you have installed on your computer?

Can you please disable Adblock extension and try again.

Can you please provide us troubleshooting information, for doing that see: Use the Troubleshooting Information page to help fix Firefox issues

sure I have 6GB of Ram, I ran a pass of memtest last week when this started but they came up fine.

I have now diasabled Adblock

Hi,

Sorry for the long wait. Hopefully you're still around. There was a bug filed for this signature

• js::detail::HashTable\<js::Shape* const, js::HashSet<js::Shape*, js::ShapeHasher, js::SystemAllocPolicy>::SetOps, js::SystemAllocPolicy>::lookup(js::StackShape const&, unsigned int, unsigned in </li>
• The bug report is here.

Two users reported that they had HTTPS Everywhere installed and when they removed it, the crashes stopped. I see that you have HTTPS Everywhere enabled as well. Can you try to disable that to see if Firefox works after that?

• (The image "new fx menu" does not exist. > Add-ons > Extensions)

hey there, this seems to have done the trick! I've not had a crash since disabling it.

Thanks for your help
