I installed Firefox recently, and it's set as the default browser. However, when certain things open, they still use IE. For example, when I click a link in WINDOWS Live Messenger, access my mail accounts through WLM or Yahoo Messenger, click a link that opens in a new window, etc. it still opens in IE.

I've tried using the program found at http://windowsxp.mvps.org/defaultbrowser.htm but it made no difference. Windows sees Firefox as the default, but still opens links in IE. How can I fix this? I'm sure someone has asked this before, but I've searched and can't seem to find it.Open new Firefox tab.
In address bar type in:
about:config
Hit Enter.
In Filter field paste:
browser.link.open_external
Make sure, that its value is set to 3.Oh, SORRY. Meant to mention that before. I found that on the forums earlier and had already checked it. It was set to 3 but it is still doing the same thing.Try my suggestion here. It has worked for me in the past.
Btw. when you click the mail icon in WLM it will always open an IE window. WLM is hardwired to do that. I don't know about Yahoo messenger but it could be the same problem.
Ok, I think I GOT it.

Some programs were set to use IE to open links. As for the rest of the programs, they have no options for changing what browser they open links in, just whatever they feel like I guess. Oh WELL... thanks anyway Also...
In Windows explorer, go Tools>Folder Options>File Types
Make sure, that following file types are associated with Firefox, not IE:
htm
html
mht
mhtml
shtml
url
xht
xhtml
xmlYou could also try resetting FF as default through Program Access and Defaults.Just may jog something from there?I have Yahoo Messenger installed and it opens Firefox in my computer.Problem has been solved with everything except Microsoft programs, which just won't open into Firefox. Oh well, that's Microsoft for ya. Hopefully I'll get all this SWITCHED over to Linux when my new laptop arrives.
