I can open Comcast.net email using internet explorer, but I am no longer able to do so using Firefox. Comcast rep says the problem is with my computer, not with their service. That is when I tried internet explorer and was able to open my email.

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:
- Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
- Under "Time range to clear", select "Everything".
- Now, click the arrow next to Details to toggle the Details list active.
- From the details list, check Cache and Cookies and uncheck everything else.
- Now click the Clear now button.
Further information can be found in the Clear your cache, history and other personal information in Firefox article.

There is usually no need to clear all the cookies.
Clear the cache and the cookies from sites that cause problems.
"Clear the Cache":
- Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
- Tools > Options > Privacy > Cookies: "Show Cookies"
Following the recommendations of feer56 and cor-el did not resolve the problem. I remain unable to open Comcast email using Firefox.
If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.
Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
The problem remains unresolved. It could be that I am not computer savvy enough to address matters of this nature. I will drop the issue and use Internet Explorer for Comcast email.
Try to create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
It is also possible that your security software is blocking cookies.
The issue was resolved by using the following suggestion: "Note: The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Consider using it before going though a lengthy troubleshooting process."
Thanks so much for your help
