I have the same problem with long Loading times in 4.2.5.0.
I'm trying to build a Twitter follow/unfollow bot. After my bot logs into Twitter I load twitter.com/twitter_user to follow or unfollow twitter_user.
The problem is that if twitter_user has any posted pictures those pictures will start flickering in the box on the left and the page will remain in Loading for 10-15 mins.
This problem can be easily reproduced by loading a Twitter user page in Actions recording, for example
http://twitter.com/aplusk.
It doesn't matter if I use proxies or not.
Is there a fix for this bug coming anytime soon?
The same template loads pages just fine in 4.1.0.0 but there is a memory leak problem with this version... After I go through 50-100 twitter users (loading the user's page and clicking the follow or unfollow button) base.exe reaches 1.5gb of memory usage and it eventually crashes the firefox instance when all available memory is used.
Was this memory leak solved in 4.2.5.0? I couldn't test it because of the problem with extremely slow Loading.
