Win 10.0.19045 , Firefox 131.0. For the last week or so Firefox has crashed out several times a day. What has changed to make this happen, and how can it be prevented?

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

I recently reset my laptop, when I logged into my mozilla account on my firefox, it is hasn't synced my passwords, hisotry, bookmarks and extensions. The sync is on, I've eevn tried to manually initiate sync. Did not work.

As I am sure as with others, the extension for True Key no long functions on Mozilla. While I understand your need for them to comply with your rules, but just pulling the rug out from under its users without prior notification could have put some of us who use it for critical reasons a great deal of anxiety. Hopefully, you are collaborating with them to get the extension back on the browser.

I cannot donate money with my credit cards through Firefox. I get different error messages from different non-profits but the result is the same - I cannot donate. I can donate to the same non-profit using the same credit cards on the same day on the same computer on Chrome. What Firefox setting might be affecting this?

On 29 Nov 2024, TBird stopped downloading all emails from all my accounts. I have not changed anything on the computer and have run all the troubleshooting routines I can find for TBird. Still not working. Interestingly, when Better Bird import the settings from TBird, it exhibited the same issues. Any suggestions?

TIA

I'm running the latest version of Firefox on Win 11 64 bit.

In looking through settings, I noticed that DNS over HTTPS, which is set to the Cloudflare default, is inactive and giving the error (NS_ERROR_NET_INTERRUPT). Using NextDNS is fine.

The problem is not unique to FF, as another Chrome-based browser has the same problem, and I have switched that to OpenDNS.

I have been through all the possible causes and diagnostics for Cloudflare not working (firewall, running FF in safe mode etc.) but can't see anything.

However, I did download the Cloudflare desktop application, and when this is running in background, the Cloudflare DNS/HTTPS settings work perfectly in both FF and the other browser.

Whilst I can of course keep using the other DNS providers, I'd prefer Cloudflare, but I don't really want to have yet another app running and consuming resources, which would be the case with Cloudflare.

If anyone has any suggestions for why Cloudflare isn't working, or how to fix it, I'd welcome them. I have searched high and low for more information, both here and elsewhere, but if such exists, I haven't found it.

I have been experiencing severe performance issues with video playback on Youtube. Videos are subject to heavy lagging, and its not just the video, but the entire browser starts lagging. This doesn't happen every time, once every few times. This only occurs on Firefox, and I didn't experience this on Chrome or other browsers. Any help would be appreciated.

I use Thunderbird as an email client, and a POP3 connection to Virginmedia to download emails. This has worked pretty well for years. In the last few weeks the email content has been very slow to load. Although the list of emails in the inbox in Thunderbird appears quickly, when I select an email to view its content there is a delay of perhaps 5s while it says 'Loading Message...'. There is a similar delay when deleting a message.

Once a message has been loaded, it can be re-visited without a delay, but if marked as unread there is again a delay next time it is read. This is also true if I work offline, so it can't be Virginmedia's server.

I have another account using an IMAP connection which doesn't suffer from any delay. Thanks if anyone can advise.

The security sequence for log-in is supply of user-id and then password; that works fine; then a send unique code dialogue pops up and it leads to an error screen which I am attaching. I have rung the number provided and they say they don't support Firefox; so that looks like end of Firefox use to me and goodbye (can't find a tearful emoji to insert).

Gotta say this kind of thing is happening quite frequently for me; mostly without a nice error screen like this one; last one I recall was hunting for car insurance; on the screen where it listed the billions of quotes to eager providers none of the links to click through for the quotes worked... and with this happeneing more frequently now you go... ohh it's firefox again isn't it... so you reluctantly fire up Google Chrome and of course it works OK.

So I'm kinda here with a broader outlook than just this specific problem; I really am on the verge of giving up with Firefox; it should just work shouldn't it; and it increasingly doesn't anymore; I don't want to get into an extended and convoluted dialogue to help you cure this issue; I'm simply perplexed that some really basic stuff doesn't work anymore; however; I've used Firefox for centuries so thought I should give you at least a chance so I could declare how I feel etc.

I am up for a dialogue over this and hoping this is an easy fix; but; as I say; I'm confused as to why, for me, Firefox just simply doesn't work well anymore; it just should and I shouldn't be here.

My e-mails are being removed from my inbox on my personal laptop regularly. I don't have an archive file set up, and in setting I have my disk space setting on "don't delete any mails", there are no messages in my Junk or Spam. I am logged in on to the same account on my work computer and there, all my emails are stored in the inbox (374 emails in inbox on work computer & only 39 emails in inbox on personal laptop). I'm unsure why this is happening, have gone through the setting menu multiple times and nothing is jumping out at me as being wrong.
