hi, unfortunately this kind of crash will be triggered by the roomy bookmarks toolbar addon that you have installed.

Hi philipp, Thanks for the reply.

Why is it that I didn't have crashes with the roomy bookmark toolbar since I don't know what build and suddenly with 56 I get all sorts of crashes?

Besides, the advantage of Firefox is the addons. Seems that with newer versions, addons are not going to work.

What's going to replace those useful addons especially Febee which I find is a very useful addon.

hi, yes that's also the disadvantage of the old addon system - legacy extensions are able to modify every bit of the internals of firefox, so breakage of any sort after an update is always a possibility.

in firefox 57+ the userChrome.css file might be an alternative to tweak the appearance of the bookmarks toolbar, https://www.reddit.com/r/FirefoxCSS/ is a good place to get started about this if you're looking for help.
