I've been trying to access some resources hosted locally with a web extension for testing, but I've been encountering CORS errors. I've added localhost to the permissions field of the extension's manifest.json, but I still encounter the CORS errors. I saw that bugs 1220810 and 1488740 addressed similar bugs in FF84, but Firefox still won't let me send the requests. If it helps at all, I've been trying to access the resources hosted on localhost from an https context, but I was under the impression that those bugs should have fixed that issue?

Ideally I wouldn't need to implement having the server respond with the CORS headers since it only seems to be a problem with Firefox in a local context. Accessing the local resources through Chrome works, and accessing the resources through the internet with the domain name in the permissions field of a production build of the extension's manifest.json works in Firefox. Is there a way to make Firefox disregard CORS enforcement for localhost for temporary extensions?

Can anyone tell me, or teach me how to tell, what's happening on the website 'http://www.syscodiscountfoodcenter.com' on the "Products" button? Whenever I click on it, the address bar just becomes 'http://www.syscodiscountfoodcenter.com/#' but nothing happens. I suspect that this is being blocked by some type of security or protection blocker, but I don't know how to determine what.

Ultimately, what I'd like to do is determine exactly what protection is being violated, then turn off this specific protection for just this website, so that I could order products. Can anyone show me a link or page that would describe how to determine what's happening?

Thank you for your help and advice.

Hi, we have encountered with the CSP issue in Firefox:

We have the following CSP <meta> tag in our application:

<meta http-equiv="Content-Security-Policy" content="default-src 'self';

                  script-src  'self' 'unsafe-eval';
                  style-src 'self' 'unsafe-inline';
                  base-uri 'self';
                  frame-src 'self';
                  media-src 'self';
                  navigate-to 'self';
                  form-action 'self';
                  object-src 'none';
                  connect-src 'self'">

As you see, we did not specified 'unsafe-inline' nor in script-src, nor in default-src. Which means that inline scripts like <script>alert(1)</script> should not be allowed to execute. But it still works in Firefox and we get an alert popup.

In Chrome and Edge the policy works fine, and blocks the script execution.

Please assist on the issue.

With respect, Victorz

Office 365 cookie issue

I have configured FF to block all cookies under "Browser Privacy" the custom setting allows "Choose which trackers and scripts to block. and I selected "all cookies". Knowing that all cookies will be blocked I logged into office 365 and allowed manually cookies through "view page info" I then selected "set cookies" to allow expecting full access to office 365 mail, but this did not occur. What happened is I logged into office 365 and could see the icons and my login name but could not read the mail.

Office 365 gave the message "we couldn't sign you in please try again" yet I could see my log in name and the office 365 icons for mail, calendar etc.. just not the actual data. If I allow cookies in Browser privacy (which i take it allows cookies always) it woks.

I bring this up because it seems like something is missing in cookies that is not represented in FF.What is the difference between browser privacy cookies and allowing it through view page permissions? Can anyone offer an explanation?

I've had all settings in about:preferences#privacy turned off for years, but a new firewall is asking me to allow default-browser-agent.exe to send data.

I'd have thought the program should stop running altogether when all checkmarks in "Firefox Data Collection and Use" are turned off.

Can I view what data is being sent?

Hello,

My firefox does't open the "New Private Window". Whenever I install firefox for the first time, the New private windows doesn't show any problem. But when I proceed, I can find out I can no longer open the new private window. Technically, the website opens, but it does not show the "purple-coloured eye glasses".

I think my computer is infected by malware because my searching histories are also saved in the incognito mode of Google Chrome.

Would you be able to fix this problem by updating the software?

When I use my McAfee anti-virus full protection software to remove trackers, all trackers are removed from my browsers (Microsoft edge, chrome, etc) except for Mozilla Firefox. I always have 222 trackers not removed from my Firefox browser after every cleaning. Gosh even chrome does a better job than Mozilla Firefox. This is getting really creepy. Anyone's assistance will be greatly appreciated.

Hi, I'm trying to disable the "restore previous session including tabs" after crash feature.

I've disabled the "Restore previous session" check from the general configuration panel.

I've changed the following values from the about:config panel: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.resume_from_crash = false

However after a restart or shutdown, Firefox still shows up the tabs from the previous session.

I'm using Ubuntu 18.04 OS.

Could someone please help me with this?

Perhaps this feature is useful for some people, but for me it's extremely annoying; plus I really like Firefox and don't wanna change browsers.

Thanks!

All was good until sometime today. FF 84.0.2 W10 up to date. Previously, when browsing FB marketplace, i could send a message about an item for sale. That send message button is now greyed out. The messenger button on the top right of my screen used to open a dropdown/popup that gave me a summary of my messages. That no longer works. I have been thru all kinds of settings randomly on FF and FB to try and correct the issue but i cannot figure out what is going on. I have tried turning Ublock on and off but that has not helped either. The only access i now have to messenger is to open it separately. I have not changed any FB settings. I did not change any FF settings myself other than trying to find out what could be doing this and exploring ublock for possibilities as that seemed the most likely culprit. Can anyone shed some light on what the issue is.

I have an ssh tunnel that I am using to access an AWS ElasticSearch instance running in AWS, so that I can see Kibana in my browser. The tunnel is necessary because access is only allowed through a specific jump/gateway host that we have setup (this is very standard).

I used to be able to access this just fine with http://localhost:9200/_plugin/kibana But then ElasticSearch updated something to require that the 'HOST' header contain the original host, ie: search-blahblahblahblah.us-east-1.es.amazonaws.com

Ok, no matter, I'll just add an entry to my hosts file: 127.0.0.1 search-blahblahblahblah.us-east-1.es.amazonaws.com

Now, I can curl just fine, and using Chrome works just fine too: http://search-blahblahblahblah.us-east-1.es.amazonaws.com:9200/_plugin/kibana

But every time I try to use Firefox, it replaces the http with https, which obviously doesn't work because the tunnel is to port 80.


Yes, I realize that *.amazonaws.com is owned by Amazon and they have an SSL cert.

I have read a similar ticket, here: https://support.mozilla.org/en-US/questions/1209387 The acceptable answer in that ticket seemed to be to use a different domain for local development, which shouldn't be too hard to do, but in my case this is not a usable answer.

I should be able to override Firefox and tell it not to change a URL that I have put into it, at least for specific sites.
