Dominik, can you give us more specific steps to reproduce this? On which websites do you see the problem? Do you get the "slow script dialog"? Thanks!

This problem is a global problem on all websites. Before the upgrade to Windows 10 all worked fine. I dont get the "slow script dialog", but sometimes the process of firefox.exe crashes.

And the more javascript is implemented in the website, the slower firefox works. I.e. facebook.com or youtube.com with a lot of ajax-Replies and other jQuery functions.

When it crashes, does it ask you to submit a crash report? Can you do that and then go to about:crashes, copy the link to the most recent report and paste it here?

Unfortunately not. Only Windows is telling me that the process crashed and closes Firefox. Restarting Firefox dont let me send a crash report.
