This problem of Firefox occasionally failing to style pages, and being able to fix it for a while when you reload the page bypassing cached files (e.g., Ctrl+Shift+r), has been reported in several threads.

One possible cause is a corrupted cache. If you exit Firefox and rename its cache folder, Firefox should re-create a fresh cache. I have to research the steps for this if you want to try it.

Another potential culprit is an external program that removes files from the cache in a way that Firefox does not detect, so Firefox fails to re-request those files until you reload bypassing cache. Samsung's Support Center software (typically on newer systems) has been identified as one program that causes this problem, but there may be others.

Thanks, I'm going to give the new cache fold fix a try and see if that works.

Changed the cache folder and it was good for a few days but started having the same problem today. Anyone else have any suggestions?

Do you have a Samsung PC with the Samsung's Support Center software?

Which security software (firewall, anti-virus) do you have?

Are you using any cleanup software that might corrupt the cache?

Does a reload and bypass the cache still work?

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

I have a Dell Studio XPS with Webroot SecureAnywhere (been using for 2 years now with no problem).

Not using any type of cleanup software.

A reload and bypass does still work.

I have not made any changes to my laptop (new software or hardware) in the last year.

Hello tmancini73, just for a check, can you deactivate Webroot (check it in Task manager for sure) and see if the issue exist ?

thank you
