Mine does something like that too. Sometimes mine will pop up and say
script so and so is not responding and then have a option to stop or
continue. What I did that helped some, installed noscript which stops
all the scripts except the ones I allow. So far, that has helped a
lot. You may want to try that and see if it helps you any. If it does,
then it is likely a script hanging up Firefox. If not, uninstall and
look for something else I guess.
I might add, I've also had this happen on Seamonkey where I have far
fewer tabs open. Usually it is a site that has a Disqus comment
section. Those hang a lot especially if there is a lot of comments.
I've had those type 10, 15 and even 20 seconds behind me and I'm a slow
typer. I'm typing along and when I look up, it can be a whole sentence
behind me but it slowly fills in if I wait.
Yours may be a browser problem only but for me, I think it is more
websites than anything else. Some just suck.
Hope that helps. It's not like you haven't ever helped me before. lol
