Firefox Support Forum

I'm trying to track down a problem in our (Java, Spring-based) web application, that seems to occur whenever some extra, unexpected requests arrive from Firefox, with no session cookie attached, and with some Sec-Fetch headers different from the requests before and after them:

Sec-Fetch-Dest=empty;Sec-Fetch-Mode=cors;Sec-Fetch-Site=same-origin

These requests do not appear in the Firefox developer panel, network tab, even with all requests selected.

But both the HTTP access log and a custom "log everything" filter show the above, with the same Firefox User Agent, no cookies, and no Referer header.

e.g. 9:13:12,426 DEBUG com.ibm.gs.houston.filters.RequestLogFilter:GET->http://localhost:9080/payment/pos?execution=e1s1 (null/false), headers:Host=localhost:9080;User-Agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:107.0) Gecko/20100101 Firefox/107.0;Accept=*/*;Accept-Language=en-US,en;q=0.8,es-MX;q=0.5,es;q=0.3;Accept-Encoding=gzip, deflate, br;DNT=1;Connection=keep-alive;Sec-Fetch-Dest=empty;Sec-Fetch-Mode=cors;Sec-Fetch-Site=same-origin;, cookies:

I'm looking for any ideas why Fx is sending these requests.

I was trying to install this flatpak, however it always saves its flatpakref (fig. 1) instead of opening it via discover.

discover backend works correctly (fig. 2).

$ plasma-discover-backend-flatpak is already at the latest version 5.24.7-0ubuntu0.1~ubuntu22.04~ppa1 plasma-discover-backend-flatpak is already at the latest version 5.24.7-0ubuntu0.1~ubuntu22.04~ppa1

I've setup any flatpakrefs to open via discover (fig. 3), however it won't work. are there anything i've forgot to do?

I use Firefox 107 on MacOs and Kubuntu and have done for 2 years in this config. Opening a zoom meeting was as simple as right click join on google calendars for both platforms. About a month ago (early Oct 2022) this stopped working. Clicking on the open zoom link in the browser does not work either. It works on mac, but not linux!

Here is the console log from a right-click open:

It will be a really big pain to migrate to Chrome just because of this bug :(

I have long been using the developer version of Firefox as my mainstay for browsing and getting Internet-related work done. Until I upgraded to 108, the Window menu remained as I set it -- in the order that I opened windows. As I have tabs grouped by subject, this worked out well given the breadth of IT and academic work that I've been doing.

Now with Firefox auto-alphabetizing the Windows menu, I'm effectively losing my tabs. Is there any way to fix this and revert to the old behavior of organizing by order-of-open-window?

For what it's worth, I'm running the latest developer version Firefox on macOS Ventura for ARM.

So, I am a Linux user who is used to shell commands like mv or cp. One of their feature is absence of prompts like "Are you sure what you want to replace foo.txt?". Because I have somewhat organized fs, I always know what that file is for and if I can overwrite it.

Now I have to download some files, what I need only for uploading onto another website / reading them once. So, I just download them into my /tmp folder and save them under the same name (so I could just repeat cat command and reduce clutter). But each time I download a file Firefox asks for confirmation to replace my existing file. Are there any config flags to disable those annoying prompts?

It is very convenient to open commonly visited sites from Firefox home, but there is no need for sites that i rarely visit.

Firefox automatically adds random sites that I have visited to empty slots. There should be option to disable this. There is a option in menu for this but it is not toggle-able.

Or is there a property in about:config that controls this? I tried some but they didnt't help.

FIREBOX can't sign in to CHATTED at HTTP://chat.opera.com/ YET GOOGLE CHROME TELLS ME WHY (capacity issue!!)

WHY IS THAT???

I've never really tracked my data usage, but my internet provider recently notified me of breaching my data ceiling. So I checked my network settings, and saw that Firefox had used 850+ GB in the past 30 days, which makes literally no sense to me. When I checked w/ peers, nothing even comes close to this. So, I guess would like to know: How does this even happen? How do I figure out what website is causing al this? And how do I stop this from happening again?

Following the last couple of updates (Currently using 108.0 - 64 bit), I've noticed that Mouseover text pop-ups do now not always appear when hovering over both bookmarks and also certain areas of websites. In an effort to correct the issue, I have disabled 'hardware acceleration' which has alieviated the problem to a degree in so far as bookmarks are concerned, but the issue still remains on some websites. I do not have this issue when using Chrome (NOT my preferd browser!). Am aware that I'm still using Windows 7, but there is a very good reason why I'm unable to update at this time. Anyone have thoughts on this issue please?

Hi,

Whenever I edit my website I always end up getting lines like this these added to the website. This means when I update the page, blank space gets added under the content for no reason.

The code generally looks like this: <script src="moz-extension://66584e7b-ef2c-4951-bd72-4fd19f1f2d7e/js/app.js" type="text/javascript"></script>

This happens automatically, every time I click edit anywhere.

Why is it doing this? PLEASE HELP!! This disturbs many of my pages as it adds unnecessary blank space!

Thanks, Akshay

Don't enable https-only mode is selected, but http://localhost is still turned into https. On both my MacStudio and OpenSUSE LEAP 15.4 machines. How can I connect to things like phpMyAdmin?

Something VERY strange happened to me tonight (using Firefox Developer Edition 109.0b3).

I opened some piano sheet music I'd never seen, by a composer whose work I'd never played, and whose name I'd never, ever searched for online.

As I often do, before trying the piece, I thought I'd see if people had already posted recordings of it. So in FF's address bar, I typed yt (my search keyword for YouTube), the composer's last name, and the piece's name in quotes.

This YouTube search-results page appeared (see screenshot), with a list of recordings of that particular music by that composer... Normal, right?

But when I right-clicked one of the results and clicked "Open Link in New Tab", the new tab told me I wasn't online. And indeed, I'd forgotten to turn my PC's WiFi adapter on.

How is it possible FF had already cached all this info—including thumbnail images—based on a search I'd never done?

Yes, I've looked up other composers' music... But does this mean FF has cached links related to every possible YouTube search for every piece by every composer?? Or is it some particularly creepy kind of privacy invasion?

Tech note: In about:config, I'd turned off network.prefetch-next but not network.predictor.enable-prefetch —could that have something to do with it? (Both are turned off now.)

Thanks for your theories! Baffledly, A.

Hello!

Currently, I have a network printer added to my computer. When I want to print something with Firefox (either a webpage or a PDF) and the printer is online everything works fine. However, when the printer is offline (turned off) the printing dialog stays on "Preparing preview". I tried waiting for over 5 minutes and the dialog keeps loading on "Preparing preview".

I tried replicating this issue in Chrome. Chrome just switches to another printer if the currently selected printer is offline. The remote printer doesn't even appear on the printers list if its offline.

I found this issue which describes the problem I'm experiencing, https://bugzilla.mozilla.org/show_bug.cgi?id=427285 However, it seems that it wasn't solve.

Is there any way to fix this issue? Thanks

hullom snce several days I canot login to my nextcloud anymore, not with any of my different user names. Nextcloud will show a login screen, I can enter my credentials, Firefox will try to connect and after a while present me a fresh empty login screen. On one of my other macs (same OS) Firefox does login ok. After deleting Firefox app and reinstalling Firefox again, the behaviour does not change. Also deleting the stored login names and passwords does not help, deleting a bunch off cookies neither. What else could I do?

I could not log in with previous TOTP any more so I used a backup recovery code to gain access to the account. Disabled non-working TOTP and now I am trying to re-enable 2FA, but every time I successfully go through the process (there is a green bar on top of the screen that says "Two-step authentication enabled"), the end result is that 2FA is still disabled and not required when logging in to the firefox account.

This image describes the same website displayed by Firefox and Chrome.

Firefox(left) uses Noto Serif CJK SC to replace PingFang SC but not all replaced.

Chrome(right) is normal(does not replace).

I can watch Fubo, Netflix, Disney etc on FireFox - HOWEVER I have deleted history, cache, installed the latest Firefox beta app and I cannot progress past the home screen of Hulu. I can watch Hulu on Microsoft Edge but would much prefer to use FireFox. I even updated to the latest NVidia Driver with no success.

I have changed bout every setting that might possibly restrict Hulu under options/preferences. Sure have not found the elixir.

Do I sit tight waiting for Mozilla to get it handled or look up a Shaman?
