Every time I launch Firefox it pops up an error stating "Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem."

Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem.

The statement above is in the pop up error box every time, when I launch Firefox. If I click ok in the box Firefox then opens. How do I fix this initializing/launch problem?

Keazen oplossing

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I did what you said & it seems to have solved it. Except that when I enabled all my add-ons & extensions the problem never came back.?.? Oh well at least it launches directly now. Thank you.
