I can access Hotmail, but unable to access messages when I click on them, nor can delete, etc. when I click on
When I go to MSN home, I sign in, go to Hotmail account and can get to my inbox, etc. However, when I click on a message I get no response; nor do I get a response when I click on another folder; or, when I check a message and try to move or delete it, I get no response. I recently switched computers (from a Mac G3 to Mac G4, same OS 10.3.9) but that doesn't seem to be the problem as I have been able to retrieve other sites and data as before.
Every time Firefox opened
Although possibly not related to your problem, I have to remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. On top of this, it has known unpatched bugs and security problems. I urge you to update to the latest version of Firefox, for maximum security, stability, performance and usability. You can get it for free, as always, at getfirefox.com.
As for your issues, let's see if the sites aren't simply having problems with such an old version of Firefox.
