Regarding extensions possibly blocking something in the page, could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

Do you recall whether this page uses any "fade" effects? Some sites fade from white or black to their final appearance and if the script which kicks off the fade fails for some reason, the content remains invisible. I'm not sure whether you would be able to tell from comparing IE.

That solution did not change anything. I don't believe the site uses fade effects, not really a graphics heavy kind of site, mostly text.

Sorry, I just realized I could visit the page and experience this for myself.

The page has a style rule display:none set for the body which completely hides it. It is supposed to clear at some point but obviously that isn't working.

To make the content visible, you can run a little script in the console, or save it as a bookmarklet for easier access, but also you should report this to the site in case they haven't noticed.

Console Method

Open Firefox's web console below the page using either

• Ctrl+Shift+k
• "3-bar" menu button > Developer > Web Console
• (menu bar) Tools > Web Developer > Web Console

Then paste this script and press Enter to run it. Then you can close the console:

document.body.style.display = "";

Bookmarklet

If this affects pages you need to visit often (as a person without an account, I don't know much about this site), you can save a script as a bookmark in a convenient location for one-click use.

To set that up:

• Select and copy the following script:
  
  javascript:void(document.body.style.display = "");

• Right-click a spot on the Bookmarks Menu or Bookmarks Toolbar where you would like to save the script and choose New Bookmark

• In the Location box, paste the script, then in the Name box, enter something you'll remember like TradeKing and click the Add button

To use the bookmarklet:

After the page loads, click the bookmarklet to execute the script against the page.

Im glad I wasn't losing my mind, that worked and I have reported the issue to them, thanks for the help :)

Note that you can also use the built-in Inspector to disable style rules.

You can right-click and select "Inspect Element" to open the Inspector ("3-bar" menu button or Tools -> Web Developer) with this element selected or select the body element in the left pane.
