hello Veen, could you tell us the exact wording of the error message or provide a screenshot of the problem?

There are other things that need your attention.

Note that your System Details List shows multiple Flash plugins.

1. Shockwave Flash 12.0 r0
2. Shockwave Flash 11.9 r900

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove all (older) version(s) of the plugin (NPSWF32) and (re)install the latest Flash player.

• (32 bit Windows) C:\Windows\System32\Macromed\Flash\
• (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

Please find 3 screenshots re.the problem. Screenshot 1 gives already the message that the browser (Firefox) is not capable of... Screenshot 2 gives a arning for a risk and I accept and press RUN. Screenshot 3 tells me "installing the java applet failed (ignore)" After pressing "ignore" it disappears, but no result uploading a map!

Cannot find the plug-ins page. See also my answer to phillipp.

I found the Flash player version viz. 12.0.0.41. Acc. to me this is the latest. The Java plug-in screen is O.K. See above and activated by me by pressing "RUN". No positive result.

Try to clear the Java cache:

• Control Panel > Java > General tab > "Temporary Internet Files" > Settings > Delete Files

Under "Delete files" I see 3 items. 2 of them are activated, should I delete all 3?

i couldn't get it working myself either when trying to reproduce the steps on google drive. maybe also report the issue to google, so that they can have a look into it...

Philipp, do you really think that Google will help in this case? They rather leave it as is. Like to promote their own browser,Chrome.

They win, because I intend to delete Firefox and start to use Chrome instead. Gives me less trouble.

The settings you need are in the Java control panel applet.

1. ) Open control panel
2. ) Open Java applet
3. ) Click the Security tab
4. ) Click edit site list
5. ) Click Add
6. ) Type the URL of the Google site, such as https://drive.google.com
7. ) Click OK
8. ) Return to add the Google applet you need.
