how do i skip broken links and already liked pages with an Imacros addmefast script ?

so i just wrote this basic script for facebook likes that works like a charm until a page wont open or a page that i already liked pops up .
is there away around this ?

i see this same problem with lots of other scrips posted here too .

you should use SET !ERRORIGNORE YES on the top of the page and also after liking don't close tab switch to tab 1 than use TAB CLOSEALLOTHERS
This way your browser wont closed if broken link or already liked
So the first lines are
SET !ERRORIGNORE YES
TAB CLOSEALLOTHERS

It works perfectly for my script hope its help

i already have the same in my script .

the thing is that it's not the browser that is closing , the script itself just stops running when a broken link or an already liked page is opened .

can I use this script in chrome?
