Sites with many off site scripts tend to crash the Ubuntu browser

Sites that use a large amount of offsite loaded scripts have a tendency to crash the Ubuntu browswer (on a BQ M10 tablet)

I cannot pinpoint what scripts actually cause the issue.
But if i load a site on another PC with firefox, then i always see heaps of off-site loaded scripts (no-script then gives a big list of url's) This is what stood out when loading a few sites that crashed the Ubuntu browser in Firefox on another PC.

Mainly news-sites / magazine style sites.

optimizily, sharetrough, demdex, clicktale, 6cs, rubicon, adobe, scorecard, jldbt, amazon, typekit, chartbeat, indexww, disqus, mediavoice, etc. The craplist goes on and on and on.

In a way i'm hoping for no-script as an option in Ubuntu browser as a way to block sites that waste ever more time, energy and mobile bandwidth. And now also waste time due to crashing ubuntu browser.
