Firefox keeps freezing with new tab even in safe mode

Question

Firefox keeps freezing, so there's no chance of even a crash report, I can only get out via TaskManager/End process. I usually have dict and thesaurus open while writing, usually with second tab my browser is a still.
It's very annoying as it's also stuck on my screen for a while so I can't continue to work.
I really need that to work or I have to switch to a different browser!
Thank you.
Here are crash reports while I still got there:

Create a new profile as a test to check if your current profile is causing the problems.
