No way.
Firefox won't affect your email.
What type of problem are you facing, you could explain in detail.

I am using Netzero webmail.This is something new.What happens is this-when I click to reply the program puts up a loading sign but nothing happens.As I stated,I contacted Netzero and they said I needed a different browser which I don't agree with.

Please reload the webpage while bypassing the cache using one of the following steps:

• Hold down the Shift key and click the Reload button with the left mouse key.

OR

• Press Ctrl + F5 or Ctrl + Shift + R (Windows and Linux)
• Press Command + Shift + R (Mac)

See if this helps solve the issues you had and please report back to us!

no help.Will probably take Netzero's suggestion and revert to an earlier version of mail program.

It's cookie problem I checked the website..

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

2. Under "Time range to clear", select "Everything".
3. Now, click the arrow next to Details to toggle the Details list active.
4. From the details list, check Cache and Cookies and uncheck everything else.
5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.
