On my desktop, when I click the Firefox icon, it sends the screen off the top left-hand corner of my computer. It just disappears. How can I open Firefox?
I rebooted my computer and when I press the Firefox icon a screen disappears into the top left corner of my computer. How can I open Firefox?

Same problem. Especially annoying when I have several tabs open but have minimized the icon to the taskbar. I can open it by left clicking on the small pop-up from the task bar and selecting maximize. It will then open to the full screen - but that's not how I want it. What's going on?

Close Firefox. Open your file browser to this hidden location:
- Mac: *~/Library/Application Support/Firefox/Profiles
- Linux: *~/.mozilla/firefox/Profiles
- Windows: %AppData%\Mozilla\Firefox\Profiles
- *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
- Windows XP: C:\Documents and Settings\<user>\Application Data
\Mozilla\Firefox\Profiles\
Search for the above files. Then rename or delete them. Restart Firefox.
Thanks for your reply. I was hopeful, but when I got to Profiles I did not find either of those files. What I found were files starting as folllows:
3arsfxjm.default
u7yaa9 06opmozs
Files, or folders? Use the search box to find those files.
Thanks., Found the xulstore file - it was in a folder called old Firefox data. I've deleted it. The localstore file was not found on my computer.
I hope this solves the problem. Many thanks.
