Known Issues (as of 2014/08/01)

We're currently working on providing a longer-term solution to these issues.
  • Images do not always appear when previewing certain websites on Firefox version 27+. We've just put out a new release candidate 4.1 to fix this issue, which can be downloaded from our homepage.
  • A webpage from coolpreviews.com keeps popping up a browser tab each time I boot up Firefox. Yuck, indeed! This happens to a very small number of systems whereby there is corruption in the CoolPreviews version number that gets stored on Firefox when a new version of Firefox or CoolPreviews is installed. This causes our "upgrade" webpage to show up, as it thinks each subsequent launch is an upgrade. To fix the above issue, very carefully do the following:
    1. Type "about:config" (without the quotes) in your browsers address bar
    2. When prompted, click the "I promise to be careful" button
    3. In the search box that appears, type "preview.isnew"
    4. Edit the value in that box so that it is "999"
    5. Close the tab
    6. Restart the browser

    The above manually sets the version number to latest build, and should thus fix the issue.

  • Google Images no longer working properly in preview window. Version 3.6 and above fixes the issue for most users. If you are still experiencing issues, it's possible that CoolPreviews is not keeping up with changes to Google Images from your locality. We've found that some users in Europe, for example, are not getting consistent experiences when browsing Google Images with CoolPreviews. Please email us and let us know your local google images URL, i.e. images.google.co.uk, as we're trying to find a longer term solution. As a quick solution, what we've found does work are searches from regular Google Search switched to Google Images. For example:
    1. In regular Google, search "Yosemite"
    2. When the results populate, from the Google Nav bar click "Images"
    3. When brought to Google Image results, preview the results and notice the images fill the entire screen.
    4. Enter a new seach, i.e. "sunsets"
    5. Note that it still works.
  • CoolPreviews window got stuck to the bottom right corner of the screen. This sometimes happens after the Firefox browser auto-upgrades to a new version. Solution:
    1. Go to Firefox Tools > Add-ons > Extensions > CoolPreviews.
    2. Click options to open the CoolPreviews user preference settings.
    3. Click "Restore default settings" found at the bottom right of the menu.
    4. Reboot Firefox.
  • CoolPreviews for Firefox seemed to stop working or no icon appears.
    Some users report that it seems that CoolPreviews all of a sudden stop working, although some remnant activity appears to remain (link still changes yellow upon hover, right-click search still exists, etc.). Diagnosis: What's happening is that a Firefox or addon update possibly caused the preview window to disappear off the screen. Solution:
    1. Go to Firefox Tools > Add-ons > Extensions > CoolPreviews.
    2. Click options to open the CoolPreviews user preference settings.
    3. Click "Restore default settings" found at the bottom right of the menu.
    4. Reboot Firefox.
  • The send feature in CoolPreviews is not recognizing my password or email address. Be sure to spelling out correctly the full email address you used to sign up. Also make sure that you've enabled cookies from Coolpreviews by going to Firefox Tools > Options > Privacy > and checkmarking "Accept cookies from sites".
  • Conflict with Firefox add-on called NoScript.
    CoolPreviews may not work if the NoScript add-on is also enabled on your Firefox browser. The current solution is to disable or uninstall NoScript via Firefox Tools > Add-ons > Extensions.
  • Conflict with Firefox add-on called Fox Splitter (formerly SplitBrowser).
    When both CoolPreviews and SplitBrowser are enabled, previews works well in the regular browser window BUT does not work in a "SplitBrowser window". No solution is available except to make sure you preview in the regular browser window instead of the SplitBrowser window.
  • Conflict with Firefox addon-called Go Classic.. When this addon is installed, images will not render in the browser after CoolPreviews is used. The current solution is to disable or uninstall Go Classic via Firefox Tools > Add-ons > Extensions.
  • "Non-Responding" Script Error conflict with Stop Autoplay.
    Users have reported that CoolPreviews gets a non-responding script error when the Firefox add-on called Stop Autoplay is also enabled. The solution is to disable or uninstall Stop Autoplay via Fireox Tools > Addons > Extensions.
