Firefox can't find the file at [http://chevy.oldcarmanualproject.com/1929_57chevyparts/57cmpc0590.htm.

Check the file name for capitalization or other typing errors.

Check to see if the file was moved, renamed or deleted.

Not related to your question, but...

You may need to update some plug-ins. Check your plug-ins and update as necessary:

• Plug-in check --> http://www.mozilla.org/en-US/plugincheck/
• Adobe Shockwave for Director Netscape plug-in: Installing (or Updating) the Shockwave plugin with Firefox
• Adobe PDF Plug-In For Firefox and Netscape: Installing/Updating Adobe Reader in Firefox
• Shockwave Flash (Adobe Flash or Flash): Updating Flash in Firefox
• Next Generation Java Plug-in for Mozilla browsers: Installing or Updating Java in Firefox

The first link you provided under Clearing Firefox's cookies and cache Fixed the problem.

The reason it took so long is I only checked the cookies box and clicked on clear now the problem was in the cache. Once cache was cleared the paged open correctly.

What was corrupted in the cache that interfered with opening that particular page? Will this happen again?

Thanks

I personally do not keep history, cookies, cache, passwords, etc., in Firefox; it is just my personal decision/preference. I also close and re-open Firefox occasionally throughout the day to "clear the trash".

There is no single answer to your question. Something got jumbled in the cache files. Yes, it may happen again. You might want to occasionally clear the cache manually or clear the cache automatically on closing Firefox:

• Manually: Firefox button > Options > Options (or Tools > Options) > Advanced > Network > (Cached Web Content) Clear Now
  • See --> https://support.mozilla.org/en-US/kb/Options%20window%20-%20Advanced%20panel
• On closing Firefox: Firefox button > Options > Options (or Tools > Options) > Privacy > [x] Clear history when Firefox closes > Settings > [x] Cache
  • Be careful what you check to clear when closing Firefox; once it is cleared there is no retrieval
