I started getting a pop up telling me something similar to "A script has stopped working, do you want to stop it or continue" with two buttons accordingly. Also there was a tick box saying "Don't show this again". I got sick of it happening so regularly and having to tick the Continue button - well it didn't tell me which script had stopped working and I wanted to Firefox to keep working and have all my plugins to continue working so clicked the Continue button, it would be good to know which script is not working so that it might help find out what's wrong and why it's not working... it's like most things that go wrong on PCs, "There has been and error, ---- will now close" Tell us what the error is so that we can report it to the programmers and they can fix it !?!?!?!?! Anyway, I ticked the "Don't ask again" and clicked Continue... Now Firefox pauses for about 5 seconds and sometimes longer every so often, and occasionally I see what appears to be this warning dialogue box flicker onto the screen for a split second...!? How do I untick this box so that I get the buttons back so that I can stop the script working and then I'll be more likely to find out what's making this script not work by some part of Firefox or a plugin then not working and tell someone about it, rather than making things slow down so much... I didn't know I had all the plugins listed below installed, where do they come from as I don't remember telling the machine that I've got Netscape- which I haven't as far as I know...?! == This happened == Not sure how often == I ticked the box telling it not to tell me again and continue...
