Developer tools has disappeared... no way to return with/without reset?

I use FF on my Windows XP machine for local web development work. I keep up to date, and I have several active extensions that are also all the updates. One day last week the submenu Web Developer lost half of its menu for no apparent reason. However, in a private browsing window, the menu is all back to normal. All troubleshooting suggestions (IE, the prefs to investigate) before proceeding to a full profile reset? See the image below

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/Firefox/tools > Modules > appearance).

  • Do NOT click on the reset button on the startup window Mode without failure.
