Firefox Community Forum

I get an error message when attempting to load the PBS main page. It was working fine until yesterday and I can get on the site using bookmarks for different shows but cannot load the main page (even from within the site). BTW, using Safari the page loads as normal.

Below is the message I get.

Application error: a client-side exception has occurred while loading www.pbs.org (see the browser console for more information).

Can you help?

Thanks, EJ

Mac OS Ventura Can provide more info as needed

I just installed Firefox on a new PC build and Twitch will load but just gets a spinning circle instead of playing the stream. The streams play fine on other browsers but i can't figure out why its lagging so bad/not working on Firefox. I did some digging and tried resetting cache and cookies and switched of recommended settings but nothing seems to work.

Hi Firefox community,

I’m currently testing a simple HTML-based site hosted on epizy.com, where I provide information and visuals related to a game mod (NullsBrawll). While everything works fine in Chrome and Edge, Firefox often fails to load key assets — especially images and script files that showcase the game’s content or guide users through the APK installation process.

Some problems I’m running into:

Game-related images (e.g., character banners, gameplay screenshots) fail to load intermittently JS-based animations or carousel sliders showing features don’t always run This issue happens more often on mobile Firefox Other browsers show the same files fine, even on slower networks

I’m wondering if:

Firefox handles free-hosted static files differently than other browsers? There are known issues with HTTP resources from epizy.com on Firefox? Any specific headers, caching rules, or SSL setup I should be aware of?

Thanks in advance for any help! Just trying to make the Game experience smooth for all browsers.

Up-to-date Firefox on Windows 11 renders a page and later renders a blank page. Toggling Enhanced Tracking Protection will cause proper rendering of the page until it goes blank again.

I do not have this browsing problem when using Edge.

I'm thinking Firefox has a bug.

I have a laptop ( screen 1) connected to an external monitor screen 2) and extending the desktop. Firefox is running on the external monitor and a site I use has frequent pop up windows with tick boxes to select. With Chrome & Edge I can get the Popup window to open on the external monitor where the browser is running, but with Firefox the pop up window always opens on the Laptop screen. Is there a setting to get the pop up window to open on the same screen that Firefox is open on?

Firefox is no longer compatible with my bank's system. I can't log in with the secure access code the bank sends to verify my identity when using Firefox. The bank says it is a problem with Firefox. Other browsers work flawlessly ... are you working on a solution? I only use Firefox unless forced to use something else ...

I’ve added an iFrame to my website, but it’s not displaying in Firefox—although it works fine in other browsers. Here’s the link to the page: https://hoploninfosec.com/ibm-flashsystem-5300/ Can anyone help me figure out why it's not showing up in Firefox and how to fix it?

Hi. New issue today. Running FF V 137.0.1. that was updated on 4-8-25. Unable to login to Credit Union online banking. Cleared browser. Nope. Restarted FF. Nope. Restarted computer. Nope. Called Credit Union: They saw no issues with account, suggested trying MS Edge browser. Boo. Hiss. Tried Samsung Android Smart Phone running FF V 136.0. Works fine. Rolled back to a previous restore point that had FF V 137.0 running. Scary stuff. Same login problem. Fired up MS Edge. Works fine logging in to CU account. I see this issue comes up occasionally. Is there a fix in the works? Will it go away AIBM? Thanks for being there. greg

When people click "update preferences" in one of our Mailchimp-Mails, they are redirected to mailchimp.com with the selection of the groups / newsletters. However, when the page is opened in Firefox, there are no checkboxes. The tracking protection blocks the image and the form only shows the labels for the groups.

Is there a way to whitelist our Mailchimp-URL ("mycustomername.us10.mailchimp.com")? Or could the tracking protection team make an adjustment to stop blocking these images on all Mailchimp URLs?

I am using Firefox as my primary browser on my windows 11 computer and two android devices. Weatherunderground.com works in Firefox android. It also works in Chrome and Edge. I am running Firefox version 37.0.1 (64-bit) on my computer (Windows 11, version 24H2). The latter was installed in January. The issue with weatherunderground arrived about a week ago. When I say it doesn't work in Firefox, I mean that it only starts to load - displays some of the day's weather and then any attempt to refresh or click anywhere freezes that website.

The Firefox window on my MacBook Pro opens but will not open any web sites and freezes. I have cleared the caches and done a Firefox restart but it is still not opening web sites and still freezing. It has supposedly sent Mozilla a few problem reports. I’m running Mac OS 15.4

My Safari browser is still working but I use Firefox as my default  browser.

I’m sending this from my iPad

On Pinterest I can see previews of pins, but detailed pins displayed as blank. It's about static pins (images) and GIFs.

If I click blank pin, it displayed in full size, but with GIF it doesn't work properly - gifs displayed as static image. Video pins displayed OK.

This problem is about Mozilla Firefox, in other browsers all works OK .

2 days before all was ok.

I did all the advices, including reinstallation Mozilla, but it doesn't helped.

All the addons are deleted, Firefox's Tracking Protection feature is disabled, in the Safe mode the problem remains.

Any ideas?

Follows the Access Denial messages I recieved when loggin onto my Financial Servicer. I have queried them also. Multiple attempts were made. I had no issues using Google and Edge.

I am constantly denied access to my online banking, my bank says, because I use Firefox, and that I wouldn't have this problem if I used Chrome - any possible truth to this? Any fix? thanks

Firefox latest version no longer wants to access certain websites. For example: "https://www.yggtorrent.top/auth/login" This site and other sites that Firefox blocks me, are accessible without problem, by Chrome and Edge latest versions. I have emptied the cache and deleted all navigation information, but the problem remains... Thank you in advance. Jacky
