can not copy and past in ebay descriptions when trying to make a listing .Also can not type in the description box will work on edge trying to list but can not as i can put information in description box. Tried on edge works fine. turned off enhanced protection still same.

In during a search this problem has happen before after updates

Content Security policy blocks essential scripts no matter what I do.

It's new Firefox installation, Troubleshoot mode, Enhanced tracking disabled, I'm not on VPN, can log into X.com in another browser just fine.

It's the reason #1 I don't use Firefox. I thought the issue would be fixed but it has been like this for long time.

Yet whatever I do, whatever I turn off this pops up:

Content-Security-Policy: The page’s settings blocked the loading of a resource (default-src) at https://abs.twimg.com/responsive-web/client-web/bundle.Conversation.721fc4aa.js because it violates the following directive: “default-src 'self'”

The screenshot is from Zen, but it uses Firefox and the issue is the same in Firefox.

With Duckduckgo set as search engine, if I type a search or go directly to duckduckgo search page the current tab crashes and the "Tab crash reporter" is displayed.

Google, Bing, etc work.

I have Duckduck privacy protections, privacy badger, and ublock origin all disabled for duckduckgo.

The alert message appears everytime I go back into gmail This browser version is no longer supported. Please upgrade to a supported browser. I checked that Firefox was last updated Feb. 26. So I'm understanding what's going on. thanks

Most times pmc.ncbi.nlm.nih.gov visited this message appears "Checking your browser before accessing pmc.ncbi.nlm.nih.gov ... Click here if you are not automatically redirected after 5 seconds."

reCAPTCHA images provided but selection of images does not resolve the access issue. Not a problem with Safari

the problem started 2 or 3 updates ago. I keep hoping the latest update will fix the problem. I can still access using Chrome. I've tried clearing cache and turning off ETP

cut and paste not working on one box on ebay listing page!

ebay sell an item. opened page appears with boxes of which one is called description. This week, the cut and paste will no longer work on that box. It works on every other box on that page! Ebay say its not them.

when i try to access my Fidelity investments and Centennial banking accounts with correct username and password the screen goes into an endless loop or says "try again later. After calling helpdesks on both these accounts they say it's a Browser problem.

После обновления Файрфокс,перестала работать веб версия мах.Будьте осторожны. Что-то выглядит не так. Firefox обнаружил потенциально значимую проблему с безопасностью web.max.ru..В других браузерах оно работает.

Today following a brief power outage I was no longer able to sign in to AOL with Firefox on my desktop computer. I am able to sign in to all other apps with no problem. I tried clearing my cache, restarted Firefox, restarted my computer and spent 30 minutes on remote desktop access assistance with AOL trying to fix the problem with no success. I can log in to my account using Chrome on the desktop computer and can log in with no problem using my Android phone but can't log in using my desktop computer with Firefox. I've verified that my Firefox version is updated. I am running Windows 11 Pro.

I would greatly appreciate any helpful advice.

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/10.0 WWW-Authenticate: Negotiate X-Powered-By: ASP.NET Date: Mon, 25 May 2026 08:15:41 GMT Content-Length: 0

Since last update...the reaction emojis on Facebook are blacked out. The entire bar of emojis are not visible. It is all black. Yet the words are visible when hovered over. There seems to be nothing wrong with the FB site and it has been suggested it could be the browser. So if you have any reports of glitches like this ...would be nice if you could fix. Screenshot Impossible to take. Thanks

Hello everyone,

I am facing an issue with my website https://ppscjobz.pk.

The website opens normally in Google Chrome, Microsoft Edge, and on mobile devices, but some users have reported that it either loads very slowly or does not open correctly in Mozilla Firefox.

I have already checked:

SSL certificate Website hosting DNS settings Cache and cookies Mobile responsiveness

However, the issue still seems to occur for some Firefox users.

Website URL: https://ppscjobz.pk

Has anyone experienced a similar issue with Firefox? Are there any Firefox-specific compatibility settings, security policies, or browser configurations that could cause a website to load differently?

I would appreciate any suggestions or troubleshooting tips.

Thank you!

Hello everyone,

We recently received feedback from a few users who reported issues when submitting forms through Firefox, while the same forms appear to work normally in Chrome and Edge.

The website belongs to Avenue Billing Services, and the issue seems inconsistent. Some users can submit forms without any problems, while others experience submission failures or no response after clicking the submit button.

So far, we have:

• Tested the form in Chrome and Edge successfully

• Verified basic form validation settings

• Checked for server-side errors

• Cleared browser cache and cookies

Before diving deeper into debugging, I wanted to ask the community:

• What are the most common causes of form submission issues that appear only in Firefox?

• Are there any Firefox-specific settings, privacy features, or extensions that could interfere with form functionality?

• What tools or methods do you recommend for troubleshooting browser-specific issues?

Any suggestions or troubleshooting tips would be greatly appreciated.

Thank you.

I am running Windows 11 Pro and Firefox 147. Beginning the second week of Feb, Chase bank will not allow me to log into their system. They say I have to have Windows 10 or higher and Firefox 128. I am running 147. What else can I do?

I could not get into my Fidelity Investments account today. (I signed up last week using same computer w/Firefox) I got to the login page but Fidelity gave me a "can't complete at this time, try again" notice. So I called them up and they suggested I use chrome. I don't want to use chrome. I tried reentering with the VPN off and on. No go.

X.com videos won't play on Firefox, one or two play, but most won't, they simply buffer with a white moving circle without playing. I have Adblock Plus and a couple of other adblock extensions, but even when I disable those, the X.com videos still won't play. They play fine on Safari. I have Mac Book Air 2022, OS Sequioa 15.6.1
