Two pages pop up when I double click the firefox icon on the desktop, the home page and the check plug in page. How do I stop the check plug in page from repeatedly popping up when I double click the firefox icon?

Chosen solution

You can fix this problem with forcing the file blocklist.xml to update.

Firefox can store multiple home pages, it is possible that the plugin check page has been set as a home page. Try resetting the home page to the site that you want as shown here -

Thanks for the reply. Unfortunately, resetting the home page to my yahoo page didn't fix the issue. The same check plug ins page still comes up with the original home page.

Type about:config in the URL bar and hit Enter.
If you see the warning, you can confirm that you want to access that page.

Pref = plugins.update.notifyUser if it shows as True, double-click that pref to toggle it to False

If that pref was already set to False, try disabling the QuickTime Plugin and then restart Firefox, to see if that is the culprit.

I checked the plugins.update.notifyUser and it was already set to false. I disabled Quick time and that had no affect to the issue either. Thanks for the response however. Hopefully there will be a fix for this soon.

I uninstalled Viewpoint Media Player (and the AOL IM client "AIM", since apparently that's what forced Viewpoint Media Player on to my system.)

Viewpoint Media Player is responsible for the plugin called "MetaStream 3 Plugin r4", and I believe this plugin is triggering Firefox to open the plugincheck page. It is not enough to disable the plugin, it must be uninstalled.

For me, after uninstalling Viewpoint Media Player, the "plugincheck always opening" problem then went away.

I uninstalled AOL IM and disabled MetaStream 3 Plugin but that didn't work either. I don't currently have viewpoint media player that I'm aware of.

Thrashard76, when you get the "plug-ins check page," I presume it is a tab opening on the Firefox site, NOT the popup listing plug-ins, extensions, etc.?

If so, what plug-ins come up with an "Update" button active? They might help us determine what is causing Firefox to load the page.

Yes, it is an additional tap page. A note: Adobe doesn't seem to update even after doing so. Also, from the Google Update plugin down, they are all unknown plugins and have "research" buttons for them. I haven't tried to research them as they didn't need to be updated like the above ones did.

This is apparently the Viewpoint Media Player plugin npViewpoint.dll. Even though you don't see the Viewpoint Media Player listed in your list of installed programs, it might be listed as a different application.

Disabling the MetaStream 3 Plugin in the Firefox Add-ons Manager removes it from the about:plugins list but apparently does not stop the PluginCheck from finding it. You should re-enable the MetaStream 3 Plugin in the Firefox Add-ons Manager list of plugins. You can then find and remove the plugin file npViewpoint.dll from your computer, using the following instructions, from this thread at mozillazine: Plugin check is happening with each start up

The Plugin Check page listed about eight plugins with status listed as "unknown plugin." It turns out that the very last one on the list, 'MetaStream 3 Plugin', which dated all the way back to 1/13/2004, was the one triggering this "Update" Nag. Here's what I did.

  1. Enter about:config into the address bar
  2. Locate the preference 'plugin.expose_full_path' by typing it into the filter bar
  3. Toggle that preference true (right click, toggle)
  4. Enter about:plugins in the address bar
  5. The resulting "Installed Plugins" list will now show the full path and file name of the associated plugin DLL file.
  6. Simply go to the directory of the suspect plugin (using Windows Explorer or whatever) and rename the DLL file (I just appended '.OLD' to the DLL file name, e.g., 'npViewpoint.dll.OLD')
  7. Quit firefox (file, exit) and restart.
  8. If you don't get redirected to the Plugin Check page then problem solved. If you do get redirected to the Plugin Check page then the plugin you just nuked (by renaming the DLL file) should be gone from the list.
  9. Repeat with the other "unknown plugins" until you don't get redirected upon Firefox startup.

I don't have npViewpoint.dll on my computer and I have 13 unknowns in the plugin check list. I don't know which is the bad plugin and I don't want to corrupt a plugin if it isn't the bad one. Any ideas?

Here's what I did (the same as what Im_bonafide did):

[quote]I did follow the steps, Open URL about:config, write: plugins.update, then I set: plugins.update.notifyUser = false. Except it was already User = false. So, I set it to User = true. When I reopened the browser it magically changed back to User = false. However, I continued to get that annoyance.

I went back into about:config > plugins.update > only this time on the line below plugins.update.notify, I (R) clicked plugins.update.url > modify > & deleted the url: replaced with my normal home page url. /quote

This did the trick as far as stopping the check plug in page from popping up. However, I still get a second blank tab (due to erasing the link and leaving it blank instead). Hopefully a patch will be made soon that will altogether stop the second tab from opening. Thanks for the help, much appreciated.

Thanks a lot for that tip. That fix you sent me (blocklist.xml) worked. I backed out of mozilla several times and that second tab never came up again. Again, thank you.

You're welcome

Now that the problem is solved, you should go back to about:config then right-click the plugins.update.url preference and select "Reset" so that the URL is reset to the default value.

Ok, will do. Thanks again.
