Firefox Support Forum

Hi there,

I read books using Amazon Kindle's cloud log in. After installing Firefox 126, I am no longer able to open books on my last page, I cannot turn pages or even open my notes. I tried using Kindle cloud on other browsers and everything works fine.

Any idea why my Kindle cloud functions are not working on Firefox?

Getting application errors on some sites – but the same site works in other browsers. This has been happening over the last couple of weeks – getting application errors on some sites but not in other browsers. On the example shown I see the login page flash briefly then replaced by the error.

I'm a university student using a website called canvas to access my uni information and work. Today, whenever I would open a module, the page wouldn't load, meaning that I couldn't access that information at all (refreshing, restarting, and completely turning off my computer did not help). I can access these pages when I checked with microsoft edge, similarly I could access these pages when I accessed them with my laptop (also using Mozilla). The main difference between my pc and laptop is that I had just, today, updated my PC to the latest windows update (2024-05 cumulative update for windows 11 version 23H2 for x64-based systems). I'm not entirely sure if it's a Mozilla problem, but im guessing that something funky is happening to my browser with the latest windows update. I have attached pictures to show whats happening / not happening .
