Main websites do not work on FF updated january 2025

[Phil]

Hi, January 2025, FF version 134.0.1 64 bits

I use Firefox since the beginning. Only Firefox.

I have a personal laptop, a Lenovo laptop, W11, less than a year, FF updated and everything is ok.

I have also a pro laptop, a Dell 5550, W11, less than 6 months, FF updated and it is a nightmare:

Since the last version has been installed, I have a bunch of websites which do not work and this forces me to move to Chrome:

Instagram : stay stuck beforer reaching the content :

Salesforce : a pop-up with error raised since the beginning and everytime I launch it :

Linkedin : stay stuck beforer reaching the content:

Whatsapp (web) : stay stuck beforer reaching the content :

Even the Mozilla sign-in pop-up does not work :

Hope this will help.

Thank you and thank you for the hard job done to have Firefox alive.

Philippe

In Mozilla Firefox Release 135.0 from February 4, 2025, WhatsApp Web does not work on this number. The QR code identifying the web session of the WhatsApp Web messenger is not synchronized and messages are not displayed in a separate browser tab. Instead of synchronizing the correspondence in WhatsApp Web, during the session, a blank screen is displayed in the browser tab. Clearing the cache and cookies of the browser does not help at all in solving the problem.

Which of the Mozilla Firefox Release 135.0 developers can help solve this problem? Need help from the developers on this problem.
Who can I contact?

The problem of breakdown and failure of WhatsApp Web arose yesterday evening, February 10, 2025 - unexpectedly. Until yesterday, WhatsApp Web worked without complaints - quickly and clearly in the Mozilla Firefox Release 135.0 browser from February 4, 2025.
To this day - WhatsApp Web does not work in the browser version Mozilla Firefox Release 135.0 from February 4, 2025

Today, February 11, 2025, I contacted WhatsApp Web support on the page: https://www.whatsapp.com/contact
My request has been accepted for processing by the WhatsApp Messenger support service. A confirmation has been sent to my email.

The operation of the WhatsApp Web application was just tested on another phone number, the same operator, in both browsers of the latest versions Mozilla and Google Chrome and it was established that this is an artificial barrier for this phone number, either from the mobile operator or from the special services of the country that can persecute me as a citizen fighting alone against corruption, repression of the unwanted, lawlessness, violation of human rights and freedoms and violations of democracy in the country.

On other phone numbers, WhatsApp Web works in both browsers with the same Kyivstar operator !!!
