User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0
Build ID: 20160623154057

Steps to reproduce:

Tried going to aol mail, the Mozilla help site and others.

Actual results:

website opened in text form

Expected results:

I am not computer savvy but I think HTML is not working.
Apparently CSS is not applied.
Does it happen when you open new tab and open the page in the tab?

If the issue doesn't happen in new tab, that could happen if you chose [View]-[Page Style]-[No Style] menu, for the problematic tab.
in that case, choose [View]-[Page Style]-[Basic Page Style] for the tab to restore the style.

If the issue happens in new tab, that could be a trouble related to add-on, can you check if that happens with safe-mode?

Thank you for your quick response.

I am not sure how to access the menu you mention. I clicked the link for directions on going into safe mode. It mentions a help button or bar. I do not see this feature. I did "refresh" Firefox and nothing has changed.
Menu can be accessed by pressing "Alt" key, but if you haven't accessed it before, it's unlikely the feature is related.

About safe mode, you can use it by opening about:support page (type about:support in location bar and hit enter),
and click "Restart with Add-ons Disabled" button.

Also, can you click "Copy raw data to clipboard" button there and paste it to text file, and attach it here?

Unable to reproduce issue on nightly build 50.0a1 [20160731030203] on OSX Yosemite 10.10.2.
Works fine for me also - with the latest Firefox 48 and Nightly 51.0a1 (Build Id: 20160803030226) on Windows 10 x64 bit.

Wesjeepman3, did you had the chance to try the suggestions made in Comment 3? Please let us know the results.

I apologize for taking so long. I was finally able to see all of the correct instructions and button options referred to in previous response by using the addresses in my MS Edge browser. :( Here is the raw data copy. I am not so sure that this issue is not tied into a recent update from ESET as I have been having issues with security certificates that for websites that I have been using for many years. Again, any help is appreciated.

I don't see any suspicious thing in your configuration tho
can you also try safe mode just in case?

I thought that was in safe mode. I restarted while pressing shift and when the option window popped up I clicked start in safe mode. I cannot remember how to copy the data to the clip board. I also have uninstalled and reinstalled Firefox.

Comment 9

Maybe this will help. Here is a certificate from a website that I have used for years with no issues until the latest update.

Peer's Certificate issuer is not recognized.

HTTP Strict Transport Security: false
HTTP Public Key Pinning: false

Certificate chain:

maybe, the request to CSS is blocked by some reason perhaps related to HTTPS ?

Can you check what's happening with the following steps?

  1. open the website that is shown incorrectly
  2. open Network tab in Developer Tools
  3. reload the page
  4. check if there's any request that is blocked or corrupted
Wesjeepman3, did you had the chance to check the steps from Comment 10?

Comment 12

This is what I started with...

www.askmrrobot.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown.
The server might not be sending the appropriate intermediate certificates.
An additional root certificate may need to be imported.


I clicked add exception and this is a copy of one of the blocked items on the "network" tab at the bottom in developer tools...

There were 8 blocked incidents just for the page listed above.
I just saw similar issue that security software is MITM-ing SSL request (the case was nod32)
Are you using some kind of security/anti-virus software?
If you disable it, or disable SSL filtering or something in it, does it help?

Comment 15

a year ago
I mentioned in comment 6 that this timed right around the same time ESET 9 updated. I am now running product version 9.0.402.0. I cannot find in the ESET settings where to turn on or off SSL filtering.
This describes how to disable SSL/TLS filtering.
Can you disable it and try again?
Wesjeepman3, did you had the chance to disable the SSL/TLS filtering following the indications from Comment 16? 
Please let us know if you are still seeing any issue after disabling it.
Closing this as incomplete due to lack of additional information from the reporter.

Wesjeepman3, if you still have the problem reproducible (preferably on the latest Firefox version) please do not hesitate to reopen the issue while providing additional details that could help us reproduce or identify your issue.
