If I compare Firefox to other browsers like Chrome or Epiphany, Firefox takes ages to load and behaves very slow. Why? I would like to use Firefox instead of others, in order to use my environment, e.g. bookmarks etc. I also tried
ssh -Y with no significant change.
Ok, this is not explaining why firefox is so slow but how you can do very similar stuff with other tools. Ok the reason for me to do "ssh -X" for firefox was, to use a special IP then, hence I opened firefox from that machine with that special IP via "ssh -X". I found this solution to my problem here:
tsocks is a very powerfull program:
Though Goolge Chrome will not work with that and maybe many other tools too, it saves me very much time and trouble. And if you concerned about the browsing environment since you are now using a local firefox just using the network traffic from a diffrent host, I strongly recommend you use the sync feature in new firefox which is also able to sync addons since firefox 11.
I am happy now :D.
