Firefox Support Forum

Hello,

I am experiencing an issue when accessing my website using Firefox on Mac.

The browser blocks the loading of an external Google Adsense script, logging the following error: "Content Security Policy: The page's settings blocked the loading of a resource". Here is an example URL:

https://www.varbes.com/

To my understanding, the site does not have a Content Security Policy ('CSP'). We don't send a CSP network header or in the HTML, so am at a bit of a loss as to how I debug this.

I don't see the same issue using Firefox on Windows, or with Chrome, Edge or Safari. I have performed a fresh install of Firefox on my Mac to make sure no extensions are causing the issue.

Other websites seem to be running the same AdSense code okay.

Any suggestions would be greatly appreciated.

Many thanks, Matt

I had to re-install Firefox for Windows 10 today after my computer crashed & I re-installed Windows. Is there ANY way to find out (recover) what my last open tabs were from my C-drive? None of my files there were compromised.

I recently replaced most of my Firefox Homepage Site Icons with custom icons. (No easy task... loking at you Mozilla)... :)

Now that I have them replaced, whenever I start Firefox the custom site icons take a long time to load.

The previous default site icons appeared to be cached and I was hoping I could force my custom site icons to cache locally to improve loading times.

Hi, all of a sudden my outgoing emails are met with the following message: ending of the message failed. An error occurred while sending mail. The mail server responded: Message rejected as spam (CM).. Please check the message and try again. These are to correspondents I regularly send emails to, and I could email them as recently as last night. Is this a firewall issue or a server issue? Please help. Karen

Hello! Since a month I have a strange problem - Firefox wont connect to any Google service - REcaptcha, google-analytics. Any site that uses these services would not load, or loads and waits until connection expires. I tried refreshing Firefox, the uninstalling and re-installing - the problem remains. I do not use any proxy or firewall on my computer. Opera and other browsers do not have this problem. Please, advice.

You can see from the first image that I had unchecked the "Block pop-up windows". But then if a page wants to pop up the windows like running "for(let i = 0; i < 24; i++) window.open("about:blank")", the result will be the second image. Firefox still keeps blocking despite my setting. And there is no even option like "allow the pop-ups" in the Options menus on the info bar.

Hello Mozilla Volunteers,

I'm having more issues with Firefox running website, such as compared to Chrome, and now I can't get past this error playing videos on the surfing website Surfline "This video cannot be played because of a technical error.(Error Code: 100000)" Any suggestions on how to remedy this would be appreciate.

Thx, Colin

(1-7-23, Windows 10): My problem for the past month is that FF won't keep me logged into sites where I specifically ask to stay logged in. It remembers my passwords but will not keep me logged in to Amazon, Yahoo, Facebook, etc. This is a home computer only used by me so I don't want to be logged out. Also, I get messages from sites saying there's a login from a new browser and I keep having to confirm it's me. It will work for a day, but when I start the computer on the next day, I'm logged out of everything.

I have done all these things:

• Refreshed FF
• Uninstalled & reinstalled FF
• Cleared the Cache
• Cleared Cookies
• Settings: Remember History
• No checkmark for Private Browsing
• Tried turning off Enhanced Tracking Protection for affected sites
• Tried changing Privacy to Custom, and un-checked Cookies to allow them
• No checkmark for "Delete cookies and site data when Firefox is closed"

I think I have solved the problem after re-starting or completely turning computer off and on again, as long as it's the same day. The next day it's like it's a whole new FF browser. This started a month ago or so. Can anyone help? Nothing I do seems to work. Thanks!

Hi there. Since a few weeks firefox refuses to open websites more and more. these are websites that can be opened without problems by other browsers (like "brave"). The error i posted above IS ONLY ONE OF PLENTY SIMILAR ERRORS shown on that occasions. It seems to be always a different one. This is going on also when i make an exception in MalwareBytes, which i am using for quite some time now with unchanged settings, and never had issues like that before. Couldn´t find any help on the support pages..... This is a relatively new problem (2-3 updates) and i want to keep using Firefox

(sorry for bad english) After closing girefox while on window mode, (accidentaly) I reopened it realising none of my accounts were signed in and all websites (youtube, adsense, gmail etc) needed google verification. and they were treating me like i was visiting first time after download. Why is that? Now I have to bring all my data back!!!???!! I am using Windows 8.1 and the latest version of firefox. No other browser installed...

Ive recently stopped using another browser that let me use alot of chrome only extensions (i use them alot as they help with different things) can you please tell me how to get chrome only extensions onto firefox? if not, why cant you just update firefox to be able to get them.

My website works perfectly in Edge and Chrome, but "View Cart" does not in FireFox. Additionally, I have the FB link so my customers can "like" my page; it does not display in FireFox. My MailChimp login repeatedly sends a verification code every time I log in with FireFox; not with Edge.

I have reviewed the recommendations for settings and nothing has worked. Using FireFox for years without all these issues. If I need to do so much to make FireFox work, I will have no alternative but to use Edge as my default browser.

Hello, I was using my headphones for watching YouTube on Firefox but then I unplugged them and the audio has stopped playing. I thought the issue was with the volume of my speakers, but the audio worked on any other app. So I plugged my headphones again and I could hear the audio from them. Anything I can do for fixing this (I even restarted the PC but the audio only plays with headphones)?

Regards, Tommaso

I can sign out and re sign in to my Firefox browser (PC) with password xxxxxxxx. ( I signed into this support page using xxxxxxxx). I can sign into my Firefox account on Microsoft Edge browser using my email address and password xxxxxxxx.

However, (using Firefox or Edge) once in Firefox manage account settings, when trying to change my password - using xxxxxxxx as 'my current password', I get a red banner stating 'incorrect password'. I now don't have an account recovery key, as I was in the process of changing this when I found that the password xxxxxxxx was called incorrect.

Just to see, tried my Firefox sync password yyyyyyyy. Did not work, as expected.

What is going on? How can I change my password? How can I create a new recovery key?

I use a website called Fanduel.com I can no longer access the site on you're browser after an update awhile back....for awhile I could press and hold a button after being denied but even that doesn't work now and I haven't changed any setting prior to getting that error message so it must have been something you guys did.
