You could try removing the extension installed or changing the startup tab using the settings of firefox.

Quoted from the Avast web site;
"The simple solution is to uninstall avast and restart your computer. If you have CCleaner then use it before reinstalling avast which is what you need to do, if you don't have the cleaner then at least run your disk clean up before installing again. Go to the avast site not a download site and download the latest free version of avast from their website, don't run the program, save it to your own computer and run it from there, if you click run and don't save initially you will more than likely have the same problem again. Once downloaded to your PC run the program from there watch carefully, untick any boxes re downloading google chrome if you don't want it and carefully watch what happens, firefox at some stage will show a screen either in installation or when you start it up asking if you want to run the program that will install the add-on you just got rid of which is the tab you don't want any more, you won't get an option to say no just a continue button, don't click it click the x in the top right corner of the box to close the window and bingo you will have cracked it, the tab will not appear again and your frustration will be over."
