Pale Moon Problems <SOLVED>

[rbeltz48]

I am using Pale Moon for Linux on my laptops. But for some reason certain websites are not displayed the way they should be. For example, http://www.wyndhamhotels.com has MAJOR problems. Except for the headers and footers, the rest of the pages are blank. Chromium displays the pages perfectly. I have also found this to be a problem on a number of websites. Are the developers aware of these types of problems?

Do you use any extension? Does it display correctly in safe mode?
Also be aware that Chrome is less strict when dealing with certain websites configurations, unlike Pale Moon, so the problem can be in the website itself.

Looks good to me, at any rate.

I clicked on the link and got the same blank pages as the OP did. So I turned off uBlock Origin 1.16.4.9 and still the same blank page results. But, this could also be a case of user agent sniffing since some websites only want to support the "big name" browsers such as Chrome, Firefox, Safari, etc.

I'm using 64 bit linux Pale Moon 28.4.0 running in 64 bit linux Mint 19.1 (Tessa) Xfce. User agent mode is Firefox Compatibility.

Moonchild,

What are you doing different that I'm not doing? Running PM 28.4.0 with MX Linux 18 Xfce. Disabling Adblock Latitude does nothing.

On a new profile in PM portable 28.4.0 32bit with no add-ons, all I can get are blank areas.
Same in either Native, Gecko, or Firefox compatibility.

Edit: Added useragent overide and it works correctly.

Code: Select all

general.useragent.override.wyndhamhotels.com
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.8) Gecko/20151126 Firefox/31.9 PaleMoon/25.8.1

Billmcct, Thanks for your help. I added the useragent override and it works great!

[Moonchild]

No useragent override in place for me - I'm using the standard (firefox compatibility) user-agent setting.
Perhaps they are checking too strict and don't like your Linux UA?

Perhaps they are checking too strict and don't like your Linux UA?

I get the blank spaces with the standard Firefox compatibility user agent setting in Windows 7, but found the site worked with a FF 52 override.

So then changed general.useragent.compatMode.version to 52.9, and the site displayed properly here with a Firefox compatibility user agent based on that.

PM 28.4, default FF compatibility user agent:

Code: Select all

Error: The stylesheet https://www.wyndhamhotels.com/etc/designs/wyndham-tablet/modules/opinionlab/oo_combined.js was not loaded because its MIME type, “application/javascript”, is not “text/css”.

Ah! that would be it.
I had my general.useragent.compatMode.version set to 52.9 in my own browser. Probably from previous testing.

Setting it back to default breaks the site, indeed, but I get completely different errors now; a whole string of:

Code: Select all

08:26:38.241 Strict-Transport-Security: The site specified a header that could not be parsed successfully.

So I'm not sure what they are doing, but it's breaking all over the place.
This is caused by a trailing semicolon, and actually doesn't pop up in an older UA version because they are trying to use it like a cache-control directive and double-up the entry, causing soemthing after the ; to show up (even if that's wrong, too).

The images are loaded from JS, and whatever JS they are using does not accept a 60.* Firefox user-agent string.

You may want to write them at accessibility [at] wyn.com to indicate your difficulties with their website. I say this because their "Website feedback" link is -also- broken. It's a mess.
