Comcat will not allow me to run Firefox. I receive a ULR not valid, can not be loaded.
I am a novice! I am not able to run Firefox. I receive a ULR not valid notice when I try. Comcast is my server bu I do not care for their format for email. I have used Firefox in the past bu have not ben able to get it to run since replacing my computer.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.
See:
- Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
- Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
