w3m's mouse support is working just fine here. Double click links to go to them.
elinks has better mouse support, though. Even has a right-click menu.
I usually only use these when I'm remoted into a machine that needs some strange driver, but that hasn't happened much for like 10 years. I remember getting locked out of X in the early 2000s all the time because ATI's graphics drivers sucked at the time, always had to load up lynx to download the drivers and try to get them recompiled right....
I also used it to browse slashdot when I was at work many many years ago ;)
To clear your cookies, btw:
$ rm ~/.w3m/cookie
To clear your history:
$ rm ~/.w3m/history
Or just both:
$ rm ~/.w3m/*
elinks uses a similar format in their tilde directory (~/.elinks), but they also have a bookmarking feature so be careful not to delete those when deleting that directory if you are using them.
