If I open a Medscape slide show, of skin lesions for example, there are 2 buttons that can be used to advance the slides: one at the right edge of the picture itself and one just above the picture. Neither of them work. When I click on the arrows they turn black as if they're going to work but nothing advances. Neither does using the arrow keys on the keyboard. Java and Flash are recently updated. The slideshow works just fine in Safari. Any ideas?

The offending extension was Blur 5.9.1720. This is a tracker-blocker. When I discovered that this was the offender I searched the Blur help files and found out how to 'allow' tracking on the Medscape site. With tracking allowed, the slide show works fine. Thanks for the help!

Use this link to check that your plugins are up-to-date. If any are listed as unknown or research, do not worry about them.


Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

Thanks! This solves the problem. The only question is, which plug-in or add-on or extension might be causing the problem? Makes me remember when you had to restart your system in safe mode and gradually add back things to find the culprit. YUCK. I have attached pix of my extensions and add-ons. Any idea which one might be the problem??

If you use extensions (Firefox/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
