Hi everyone, my website YouTube Thumbnail Downloader

is not loading properly on Firefox, while it seems to work on other browsers. Sometimes the page loads partially or shows styling issues. Has anyone faced a similar problem, and what could be causing it? Any help or troubleshooting suggestions would be appreciated.

Hi,

I'm seeing a strange issue in Firefox when using an online work-hours calculator for payroll calculations.

On this page: https://mauricettecalcul.fr/

When I enter certain hour and minute values and convert them to decimal hours, Firefox occasionally returns a slightly different rounded result compared to Chrome on the same machine. Because these figures are used for payroll, even small rounding differences can be problematic.

I've already tried clearing the cache and testing with extensions disabled, but the behavior remains.

Has anyone experienced browser-specific rounding or calculation differences in Firefox with JavaScript-based calculators? Is there a way to identify whether this is a Firefox issue or something related to how the site handles numeric calculations?

Thanks for any suggestions.

I have recently discovered that Firefox is constantly sending data at around 3KBytes/S to a variety of Cloudflare servers.

What is the data that is being sent and why is this happening?

This has started to occur in one of the last updates to Firefox.

Currently running 151.0.4 (64-bit) on Windows

Does this constitute a privacy violation, what is the data that is being sent?

When I click the firefox icon on my desktop, I cannot open firefox because it says Cannot transfer data from s.aolcdn.com

Hello,

Since this morning, I haven't been able to access Bsky on my laptop because of a supposed HSTS risk, which means I can't add an exception to visit it. I use Firefox on my Android and going to the mobile version of the website lets me in no problem, so I assume there's an issue with my laptop.

I'd usually wait a few days and let it solve itself but just in case it's something on my end, I'd like to solve it! I'm on 151.0.4 (64-bit), don't use a VPN or an anti-virus, I have a couple of privacy add-ons but they've been here forever and they've never caused a fuss. I can post a screenshot of the error code and the certificate it sends me if it's any help.

I'd appreciate any pointers! Thanks!

Every time I run Firefox 152.0b10 on Macos Tahoe 26.5.1 Mini it flickers and crashes. Its reporting a webrender compositor error. I made a new installation and it worked but I will have lost all my extensive userChrome/Content customization, as well as hours of time today and more hours to come transferring across and doing things like typing this out and checking versions.

And it flickers awfully on the new installation so is unusable. What should I do? I'm typing this on my Macbook Pro with M3 Pro & Macos Sequoia 15.2, which is not running Tahoe as it bricks all the Adobe software on the laptop. I refuse to rent Photoshop and Premiere for the exhorbitant price Adobe charge, and am transitioning to DaVinci products but not yet done learning.

I have cleared all caches, reset all the hardware acceleration stuff to off or force-disabled, and done everything else suggested by any and every AI agent, like switch off Widevine for a bit then on, or stop UBlock0 running in any way, shape or form. Things change when such things are done but don't work.

I want to be able to make voice and video calls via facebook messenger using my PC camera and microphone but, the message I get is that "voice and video are not supported on this browser (Firefox/Mozilla) . It is supported on other browsers. I really don't want to switch browsers, I love firefox. I did find a couple possible fixes via advanced WebRTC settings but everything seems fine, i.e. it is clicked on true not false. I need this soon, can we get settings changed?

I fill out a lot of forms online and use Firefoxe's autofill to fill in my personal info.

The problem I have is that autofill always puts a +1 in front of my phone number on the forms.

Since the form is only looking for 7 digits, it chokes with the +1 and won't submit. This requires me to manually click on the phone number field and delete the +1 so the form will submit. With the amount of forms I fill out, this creates a lot of unnecessary wasted time constantly having to correct it.

I have tried editing the phone number in autofill to remove the +1, and although it appears to do so, as soon as I save it, it comes right back again.

Is there an about:config setting that will remove this? I don't know why Firefox thought this was a good thing and not allow a way to edit it out.

Thank you for any replies

I am on iMac Tahoe 26.5.1. I cannot use Netflix, or HBO Max. Both say that my brower is out of date. My sofware indicates that my Firefox is the *latest version available. Please advise.
