I stopped my Firefox 6.02 from upgrading to Firefox 7.0 when Firefox reported that the Slingplayer app was not compatible. Perhaps the SlingMedia folks are still working on an update to their application to make it work with FF 7. I suggest you back down to FF 6.01 or 6.02 for the time being to watch your SB through the web browser.
Hi stower2422 and chakkarinen, here are the requirements to use Watch.slingbox.com please make sure that the computer that you have meets these requirements.
Sorry, RafaelB, but the text on your link for browser compatibility is not accurate. Your text says Firefox versions 5 and above (32-bit only) are compatible, but as of today, the new Firefox version 7 still gives a warning message that the Slingmedia add-on is not compatible, then Firfox 7 disables the Slingmedia add-on and reports that it weill periodically look for a replacement. So far, no replacement has been reported to me by Firefox.

Many thanks to phrelin, who found the solution to the Firefox 7 update issue. He writes:
"After I installed FF7 in its own directory and clicked on my Sling bookmark and the "watch" link, it went through the updated add-on install routine. It works fine."
So, following phrelin's instructions, I first uninstalled my current version of Firefox 7 (and NOT clicking to box to discard personal settings), then reinstalled Firefox 7 using "custom" instead of "standard" option. Then, on the screen where the installer shows the proposed file location for the programs, I added a "7" between Firefox and the forward slash. Then continued the installation. After finishing, I started the new installation of Firefox 7, visited http://watch.slingbox.com, and the SlingMediaPlayer plug-in was correctly re-installed this time.
