The drop-down menus work fine here. Maybe you've got an add-on or setting that is blocking the script? If you close Firefox, then start Firefox in Safe Mode, does the problem still occur? To start in Safe Mode, go to Help > Restart with Add-ons Disabled.

If the problem does not occur in Safe Mode, then you can disable your extensions one-by-one until you find out which one is causing the problem. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.

The only other question I can find from you is https://support.mozilla.org/en-US/questions/928846 which seems to be about a different issue.

I have no extendions/themes installed.

I tried restarting in safe mode...Stilll fails.

I made a new partition and did a clean basic install of windows 7 and firefox 14.01 and it still fails.

Try resetting Firefox: https://support.mozilla.org/en-US/kb/reset-preferences-fix-problems

Have you noticed issues with other mouseover scripts? For example, you should get a close-up displayed to the right of the product image as you mouse around over it: http://gifts.redenvelope.com/gifts/gorillatorch-flexible-tripod-flashlights-30051382

Maybe also check the mouse driver to be sure to have the latest updates.

Try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

I've been playing around with the privacy options.

if I change "Firefox will": use custom setting for history and change Keep Until: they expire or i close firefox

the mouse over works just fine on the web site,

but if i change the option - Keep until : ask me every time.

The mouse over fails. I've always had it set to - ask me every time and it started failing a couple of weeks ago. I would like the option to decide wether or not a cookie is stored or not.

And yes the mouse over works every time on the red envelope web site, no matter which keep" until option i have set (all 3 options work)

I can't think of any connection between the cookie method and the menu. Perhaps you have Block for the domain that appears to host the menu script: img-dpreview.com? You can check the Exceptions dialog and edit as needed.

I would like the option to decide wether or not a cookie is stored or not.

I used to do that myself. Years and years of thinking and clicking. I eventually set "Keep until: I close Firefox" and I manually create an exception for sites I really want to remember me. Saves so much time.

I've the same issue with http://www.caspiangifts.com/ when I move my mouse to drop down mane it doesn't work, as soon as I moved it down the menu get disappeared.

Hi thomasmgrasso, that menu is working for me in Firefox 17 on Windows 7. Are you on a different version/OS?

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Bypass Firefox's Cache

Use Ctrl+Shift+r to reload the page fresh from the server.

(You also can clear Firefox's cache completely using:

orange Firefox button or Tools menu > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now")

(2) Remove the site's cookies (save any pending work first) using either of these. While viewing a page on the site:

• right-click and choose View Page Info > Security > "View Cookies"
• Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"

Then try reloading the page. Does that help?
