I-Firefox Community Forum

Hi,

I am developing a website of my own and in that website I want to implement a handler for Content-Security-Policy violation reports. I want to test if this handler works as I expect and therefore I have configured a webpage such that is will report CSP violations (I see them in the web developer console) and I want to have them sent to my application's CSP-violation handler.

In my test environment, the application is running on localhost. I have run my web application both on HTTP and HTTPS (with a self-signed certificate), but in neither case Firefox is sending any reports to my application.

My CSP headers look as follows: Content-Security-Policy: report-uri http://localhost:5281/csp-violation;base-uri 'none';default-src 'self';form-action 'none';frame-ancestors 'none';report-to csp-viol;script-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg';style-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg' Reporting-Endpoints: csp-viol=http://localhost:5281/csp-violation Report-To: {"group":"csp-viol","max_age":10886400,"endpoints":[{"url":"http://localhost:5281/csp-violation"}]}

When I run my application using HTTPS, all HTTP in the endpoints will also be HTTPS.

I have verified that when I post something by hand to http://localhost:5281/csp-violation, my handler is executed, so that is not the issue. I believe that Firefox is just not sending the reports. Is there a way to configure Firefox such that it will send the CSP violation reports to my application when run on HTTP(S) on localhost?

Sincerely, Marcel

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

macOS. Firefox is running. I enter: open -a Firefox --args -private-window "https://apple.com" (in Terminal or Automator) which I believe should open apple.com in a new private window, but although the focus change to the already open Firefox window, a new private window does not open. It does work (apple.com opens in a new private window) if Firefox is not already running, but I thought the -private-window argument is supposed to open a new private window whether Firefox is already running or not. What have I got wrong?

Hi MFirefox

I'd like to cancel Relay. I have been having problems with getting logged onto sites that I need quickly. This morning Norton would not let me on to see my privacy report.

Please tell me how to delete/cancel Relay.

Thanks, [email removed]@frontier.com

I have noticed in the past few weeks or so, many video play backs are erroring out on google/news: Example: https://6abc.com/post/middle-schoolers-create-20-fake-tiktok-accounts-impersonating/15039963/

Message is: Media could not be loaded, either because server or network failed or because format is not supported.

IMO not a network issue......

Thanks John Hutchins

I have been trying for a house but won't open, so I tried another Browser and the Email account opened first time. What have I done work or what can I do to fix. Firefox is my #1 Browser. Email removed for privacy

When I open my youTube home in Firefox browser is completely blank nothind is showing I don't have this problem in other browser. I have tried in the settings to turn the history on and off but nothing has changed.

Despite having the Pop-ups box ticked, I continue to get these 4 in a row, from McAfee. I have been running a system clean for 3 days, and still get these pop-ups. I have TotalAV, but nothing I do has made a difference.

Corel asked me to do a screen shot of the issue: Attached When I look at the changed screen, There is an icon infront of the Web address line that looks like a robot. When I rollover it this statement comes up: Browser is under remote control reason (Dev Tools) All of the address bar is inpink. I copied it but color does not copy. when I did the screen shot the address line is not copied. https://support.mozilla.org/en-US/questions/1449321?utm_campaign=questions-reply&utm_source=notification&utm_medium=email

daThis is still frustrating. I do not like to use the browser when something else appears to be in control. I have MacAFee and run a scan but nothing shows up? If developers are following my browser, I should beable to turn this off.

Webpages don't open on Firefox and a link is clicked (for example, a link in an email). This problem does not happen when using another browser. I followed the advice given to someone who had the same problem. Switching to "No proxy" as suggested did not correct the problem. The advice was from zeroknight and is pasted below: zeroknight 12/1/23, 1:28 AM more options The browser settings are in the menu that looks like three horizontal bars (≡). From there, go into Connection Settings and change "Use system proxy settings" to "No proxy".

Refreshing Firefox did not correct the problem

Hi,

just for understanding:

Why can the Firefox source code (view-source) of a website be nearly three times the size compared with Chrome/Opera or when I save the Firefox source code marked and copied and then pasted and saved via an editor?

Example: Firefox 546,6 KiB Chrome/Opera 204,3 KiB via Editor 204,3 KiB (marked and copied Firefox source code)

Best

When I open a page from Fox I get a message in a ribbon" Firefox is installing components needed to play the audio or video on this page. Please try again later." Really everything seems to work and there is an x to close the ribbon. Just wondering if I need to adjust any settings. Thanks

On Opera and Chrome, I am logged in as a google user. I make a diary available from a web page which is limited as to how the viewer sees it. If I (or another authorised user) is viewing it then they see all the detail. If anyone else sees it then they only see 'busy' against all the bookings. This has worked fine for years.

On changing to Firefox, though, when the web diary is accessed - even though I am logged in properly - it only shows the 'busy' view. It seems as if it's not maintaining my google login, hence showing the 'incorrect' view.

Is there anything that I can change to make this work properly?

TIA

Hi

When I use Firefox to act as a browser to search for topics I get the error message

EC_ERROR_REVOKED_CERTIFICATE

I am now having to use "Bing" to search

This has been going on for a long time

Thanks Gareth

I get this msg from FIrefox when I try to login from the webpage kp.org. I have no problem on Microsoft Edge.

"The page isn’t redirecting properly"

Also on NBCwashington.com/weather the video doesn't play on Firefox but does on Microsoft Edge. I contacted NBC Washington local station and they can find no problem on their web page.
