Fun stuff: crazy UA strings overrides

[KNTRO]

Hi all,

I went to about:config and rode the site specific user agent strings overrides. All of them were modified as:

Code: Select all

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:45.9) Gecko/20100101 Goanna/3.0 Firefox/45.9 PaleMoon/27.0.3

At first sight, this UA works for most of the sites^*, so maybe a review of which websites still need these overrides would be a great idea.

Then, I found that some —supposed— demanding websites for latest web browsers' state of the art technologies, actually care very little. Here are some examples^* of the minimal user agent strings needed for every website to work.

Code: Select all

general.useragent.override.calendar.yahoo.com

Gecko/ Firefox/1.0

Code: Select all

general.useragent.override.chase.com

Gecko Firefox/35

Code: Select all

general.useragent.override.gaming.youtube.com

Gecko Firefox/35

Code: Select all

general.useragent.override.privat24.ua

Firefox/25

Code: Select all

general.useragent.override.web.de

Firefox/50

This is fun: if you use any of the Pale Moon's regular user agent strings with those sites, they're gonna tell you —in its homepages— that you're using an outdated/unsupported web browser, but if you use those silly UA strings in its homepages, they won't advice you a thing! WTF?!

^* = I didn't log in every website though. Only loaded the homepage of everyone of them.

UA sniffing is bull shit.

Of course crazy UA strings are going to work if you find out what substring their sniffer is going to check for. It doesn't have to be a common string at all, as long as it "matches" what they check on.
