Hey, I am currently working on an application where I want to upload files to a server using mtls via a webapp. The upload goes to another url and server than the one where the webapp is served from. If I test the file uploading without mTLS, it succeeds, and with mTLS enabled it also works in chromium, but in Firefox I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <url> (Reason: CORS request did not succeed). Status code: (null)." on the `OPTIONS` request before the `PUT` is done. The client and the server both have a certificate from a custom CA, which I imported into firefox, along with the private key. Does someone know what the issue here might be? I am suspecting that there is some problem with firefox loading the user certificate on the preflight request?

Consider the following scenario: I want to go to "nextcloud.com", so I go to the address bar and start typing. Unfortunately, I make a mistake, and the first character I type is 'b'. Firefox then offers the autocomplete "bc.co.uk", and highlights it. I type another different letter, the added autocomplete offer is replaced with the character I added, and it will try to offer another autocomplete suggestion with all the characters I have typed so far. However, I realised the 'b' was wrong, so I press <backspace> then start typing "nextcloud.com". Of course, the backspace key now only removed the autocomplete suggestion, leaving the original 'b' I typed (so I now have "bnextcloud.com"). My question: Is there a way set configure firefox so that the key sequence 'b' followed by '<backspace>' to return the address bar to the original (empty in this example) condition? If this means turning off auto-suggest, I am happy to do that, since I don't use it anyway.

Thanks.

Hi there! I find the new sidebar (on the left for me) a great addition but is there a way to reverse the "top to bottom" tabs displaying order?

Not a way to move tabs, but a setting allowing, when opening a new tab (Ctrl+t), to place (and display) the icon on top of the tabs icons pile, not at the bottom.

I get that it's the opposite of the normal reading direction, but it's rather unnatural to go looking at the bottom of the screen for recently opened tabs, IMHO.

Thanks in advance if you can address this, or show me where I can find such setting.

Best regards from France, Jc

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I'm using the AI Chatbots plugin in the sidebar and I'm trying to log into Claude, but the plugin keeps asking for a verification code and Anthropic only sends a magic link email which doesn't work in this situation.

Does Firefox still support automatically updating the opensearch XML description? MDN still mentions this feature: https://developer.mozilla.org/en-US/docs/Web/XML/Guides/OpenSearch#supporting_automatic_updates_for_opensearch_description

Also, in about:config, there used to be an "browser.search.update.interval" entry that specified the update interval. I can't find it anymore.

If this isn’t the right place to ask, could you point me in the right direction?

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

Tried to sign in to Firefox on a Linux laptop; searched for a password and finally found it under "a" for accounts;maybe my error. Tried to sync. bookmarks etc. from Android phone and it suggest two non existent menu options: Sign in and - i've forgotten; Sync between devices maybe; anyway nothing resembling either was in the menu so it is at least satisfying to know you can delete a browser with no concern that anything useful or even functional is to be missed.
