Hello everyone,

While testing some fan-made game community websites, I noticed that Firefox handles them a bit differently compared to Chrome or Edge. For example, I checked https://nullsbrawl.tech/ (not an official site, just a community project) and saw that it loads more slowly and sometimes behaves differently in Firefox.

This made me curious:

Does Firefox have different handling for script-heavy or unofficial community websites?

What tools in Firefox Developer Tools would you recommend for debugging performance issues?

Are there guidelines for developers to make such sites more compatible with Firefox?

I’d love to understand more about how Firefox manages these situations.

Thanks in advance for your help!

I just wanted to report that a company recommended to me for a Password Keeper may be a scam.The company is called Keeper Security, Inc., out of Chicago, Illinois. They have a Password Keeper that gives you new user options for monthly, quarterly, and yearly subscriptions. I signed for monthly, with a new user amount of $1.67. They charged me the quarterly amount of $21+ ... which will be $39.99 the next quarter. I contacted them about their error, but have not yet received a reply. I just wanted to warn you so you can warn other Firefox users that this could possibly be a scam! Thank you.

So, my comment in a review for Mozilla android asks me to post here - so my information will be disconnected with that - the email Mozilla provide for support is never read - so it seems Mozilla have zero commitment to helping users by fixing issues. I think my time using the app will be very short, but who cares - certainly not Mozilla. The issue is that navigating telegraph.co.uk is a pain - go to a page to read an article - then go back to the main page - it goes to a random different location on the main page - so waste time finding my place - it's nonsense.

I'd like to revert back to the old style menu on mobile. How can I do that? The new menu is terrible and often requires twice as many clicks to do the same things as the old menu saving no time while also taking up more screen space as well as moving menu options around from where they've been for many years for some arbitrary reason.

On a certain website, starting only after I installed the latest update,when I attempt to type into a text box nearly the entire screen disappears and goes white. Before, the screen did not change and I could watch the words I was typing appear in the text box. Now, I can see nothing. I'm typing, and when I minimize the keyboard (Gboard, same as I've always used) the screen goes back to normal, but while I'm typing there's nothing but white.

Occasionally/rarely, this does not happen and everything works as it did before I installed the update, but most of the time I get the white screen.

I did not update anything else nor do anything with the settings. I literally posted a message on that site, updated Firefox, then went back to the site and suddenly had the white screen problem.

I'm attaching two images. One is a screenshot of the discussion showing the text entry box and the other is a photo of what the screen looks like when I tap in the box to enter text. I cannot get an actual screenshot of the white screen because attempting to take one minimizes the keyboard and the problem only occurs when the keyboard is in use. I masked a lot of stuff on the images because it's a private and secure site. I'd be willing to share more information only with the Mozilla technical team.

I updated to version 142.0 on 26 August 2025 on my tablet running Android 10. When I went to my favorite website and tried to enter text into a text box in a discussion forum the screen went dead white behind my keyboard and brlow the URL bar. I couldn't see what I was typing nor anything of the website (which has a black background).

This is repeating on discussion forums but not in private messaging. As soon as I make my keyboard (Gboard, latest release) disappear the website comes back.

Definitely related to the update, as five minutes before I downloaded it everything was working perfectly. I cannot get a screenshot because as soon as I try, Gboard disappears and the website screen returns.

Any ideas?

(Also, is there a way to tell Mozilla directly rather than crowdsourcing a tech problem they created?)
