well just a suggestion , maybe u changed the install path of fire
fox , like u had firefox 2 and installed 3 and it got installed in a
new folder so it will tell u cant find the firefox.exe when ever u try
to click any shortcut so try goin to the path "C:\Program Files
\Mozilla Firefox" or something and get the exe file ur self and the
right click it and then "pin to start menu"
if that doesnt work i guess ud better uninstall firefox completely and
then reinstall it, but then ud lose all the saved passwords though
there is a certain file that u can back up for that but i dont know
its name since i use a plug in to back up my passwords , and then the
bookmarks could get copied and saved from
"C:\Users\<your user name>\AppData\Roaming\Mozilla\Firefox\Profiles
\<random named folder>.default\bookmarks.html" as a vista path or
"C:\Documents and Settings\<your user name>\AppData.." dont remember
the rest , cause i have vista , but ull hopefully get to it.
so after backing up ur bookmarks u could uninstall firefox from the
"Add and Remove" from "Control panel" then install a fresh copy, o and
write down a list with all ur add ons because ull need to reinstall
that too, yea its kinda annoying.
you also might want to try "System Restore" , too many options i
know , u didnt give much information so im trying to think of all the
possibilities , any way good luck and reply if u have more details or
need something
