Приветствую! Подскажите, почему не работает смена User-Agent на сайте https://online.vtb.ru в брузере ФФ 52 http://ipic.su/img/img7/fs/screenshot2021-10-20002.1634733461.jpg http://ipic.su/img/img7/fs/screenshot2021-10-20001.1634733200.jpg

Does it works on other web sites ? Could you give me an export of your configuration (export button of the SimpleModifyHeader config screen)

Could you check with the dev panel (F12) if the header is modify using url https://online.vtb.ru/favicon.ico

Do you have any other plugin installed on your firefox ?

On your picture , i do not see the request header

StVol33 commented 3 years ago

What should I do to make it appear?

didierfred commented 3 years ago

I do not have the same version as you , if you click on the arrow before the url , you may have more information

StVol33 commented 3 years ago

ОК! It shows FF 92: http://ipic.su/img/img7/fs/screenshot2021-10-29001.1635506700.jpg But why does the site say "the browser is out of date"?

didierfred commented 3 years ago

The web page is probably detecting your browser via javascript code and not via the request header .

See for example : https://codepedia.info/editor-example?id=47

Interesting! Then why, if I use the User Agent Switcher extension (https://chrispederick.com/work/user-agent-switcher/) and change the User Agent there to FF 92, then the site https://online.vtb.ru/ shows acceptable browser? http://ipic.su/img/img7/fs/screenshot2021-10-31001.1635680353.jpg

I add a look to the code of user-agent-switcher , it s because the plugin is not modify the header but is setting the user agent by setting user preference via javascript https://github.com/chrispederick/user-agent-switcher/blob/c98c287ac7e20ebfd38cbb12fd59613cdabce368/development/source/content_common/useragentswitcher/useragentswitcher.js#L439
