H A Forum I use extensively suddenly started showing content layed out in a sort of linear fashion where everything was set onto a new line. I have used this forum for more than 18 years and this is the first time this has happened, The site is a respected one, and a search for 'MSDN Forum' would provide a link(s) to my problem site. After a LOT of work trying to find what has happened has resulted in my finding that scripts and CSS seem to be skipped from being loaded by Firefox reporting the error message I mention in the title. These errors are MANY thoughout the incoming data. I subsequently tried to pursue Mozilla articles on Mixed Content Blocking, which seems to say Ishould have an option to 'disable' Firefox security with respect to the above via clicking on the 'sheild' icon and follow through to where there is supposed to be am option to 'stop/disble' - but there is no such option here so I can't check if that option is a cause of my issue. This issue is very severe as it disable ALL of the needed buttons - such as Reply, Quote and Post New Question - for a Forum, that is indeed severe! Now, I don't know if this whole issue is a fault with either Microsoft (who seem to be serving faulty data, or, Firefox for being overly coseting) I attach an image showing a portion of the errors (they extend throughout the entire list). Patricularly, the line at the top saying the Style Sheet could not be loaded summarizes the whole issue. Is there any other way I can get to disable Firefox being overly protective - I do know how to use the About:Config etc., but lack the ability to find anything relevant to this issue in any of the content there.

A further snippet of information: amongst other things, I reinstalled Window 10 and used Edge immediately after install had completed - same issues (suggesting that either both browsers are overly protective, or that the issues stem from Microsoft). I have tried most/all of the things likely to be suggested here suxh as using Safe Mode, no Extensions etc.

To save readers from becoming bored with this long essay, I'll stop here - if further info needed, just ask.

Can you load these files directly via the location bar ?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

Firefox shows an highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content.

  • click the shield icon for more details and possibly disable the protection

You can check in the Web Console what content is blocked.

Thanks for your reply. I don't understand the 'files' you ask if I can load? The issues are regarding CSS styles not being permitted to load for the incoming pages. (NOTE: only these MS Forums are effected - no others) All of the other suggestions have been tried (fresh OS install, fresh FF install, new computer tried etc.)


As I mentioned in my first post, I tried everything that I could think of - including safe mode (no extebnsions), brand new Windows 10 install and problem still there right from the install. I have since tried another computer here, with Windows 10 also, and the latest Firefox fresh install, no extensions and issues exactly the same.

I used the 'Inspector' to make the screen shot I posted above, showing the errors as the page(s) load. All pages have very many of these errors, and, of course, at the top of the display is the error message I used in the title of my question.

The screenshot shows that the developer tools aren't able to load one or more style sheet files. If you paste the URL in the location bar then you can check what happens if you try to open such a CSS file directly (i.e. the server might display and error message or Firefox might display an error page).

Hi Sory for delay, been away/busy. Thanks for your further reply, I see what you mean. Here is what I got whan trying your suggestion. It seems that the problems stem from MS - as my last/latest attemp (new computer, no additional software added, Edge) showed exactly same issues for that site only.

Here is an example (all other errors are same result)

========

Test file load attempt:

Result: dialog Error box with:

Hi

OK, I have found the source of my problems.

My ISP had introduced a new feature they call Web Protect. They stupidly decided that it should be enabled by default instead of letting users know of its existance and allowing the user to decide if they wanted to enable it.

Strangely, the ISP technical department at BT Internet, one of the largest Internet Providers in the UK, did not consider this during a very long telephone call with them. Maybe the technical team didn't know that the feature had ben introduced either!

It was a member of the BT User Forum that pointed me to this new feature, and that person was a member of the public not a BT professional!

So, one sillly button click to disable the feature is what cost me many hours of tribulation and many ££££.

Thanks for the contributions.
