I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

I want to visit http://bispebjerghospital.dk/ . I have seen on https://www.whatsmydns.net/#A/www.bispebjerghospital.dk that it's DNS isn't propagating correctly, so I turned on "MAX PROTECTION" for DNS, hoping that it would let me see the site.

But Firefox showed me "Unexpected error" the first time I went to the site. And then I clicked 'always allow' and now it just spins and spins with no response visible.

How can I visit the website from one of the countries with red X's on whatsmydns?

Whenever I open Firefox on Chrome OS, which I installed via the Linux shell terminal, it says in settings that the browser is managed by my organization. However, I don't have a school account signed in or anything.

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

Hi,

I have Firefox 102 ESR in Debian 11 (LXC in Chrome OS). It is the en_US version with Czech spell checking dictionary installed as an add-on. I can switch the spell checker from English to Czech in ordinary text areas by accessing the context menu via a right mouse click.

However, I'm using a proprietary e-commerce system (Shoptet) with a WYSIWIG editor that has its own context menu, overriding the default one in the browser. I can't switch the language for that reason. Is there a way to switch the spell checker language for a particular text area without access to the context menu? Thank you very much.

Hi guys!

Sorry for dumb queston, just Iam not a web-dev) My problem is next: I need change default code page (charset) for every document. Its only one charset for all pages, so it can be hardcoded. Due no one another charset web-server do not use.

 Can you pls say how it can be realized? Should it be done by changing some settings files, or maybe need some code changes ( for example at intl/locale etc) ?

Regards, Ruslan

FireFox assumes that text size is the same for all pages in a domain, rferl.org for example. That is _not_ true. If I have set size to 50% and then take a link to a page that's different and have to set size to 67% to read it, when I return to the original page, size is 67% and text is too large.

Dear friends,

Firefox on Linux does not allow entries in forms that are called up in IFRAME. It works perfectly on Android.

Does anyone know why this is the case? Uwe

Firefox 127.0 (64-Bit)

I'm using last release Firefox in a fresh install of Debian 12 with KDE. Trying to personalize colors and get a coherent style, I've installed Firefox Color and it worked fine, except for a few GUI elements.

I solved the scrollbars part with this answer:

https://support.mozilla.org/en-US/questions/1419353

Is there a similar setting for the menus? I mean in Firefox's menu bar or the ones popping over the page. The dropdown of the burguer menu and the bookmarks toolbar do get styled (I will include images showing the difference).

Thank you in advance and to zeroknight for sharing the bit about scrollbars!

Just like the Android version of Firefox does! It opens the new tab(s), but load each tab at visit!

Desktop Firefox also does this at [History / Restore Previous Session]. All the previously opened tabs are opened again, but each of them only loads at visit.

This is I would like to have as default behaviour with newly opened tab(s) in Firefox. > Tab opens. > It hasn't loaded yet! > At visit it loads the content.

PS: I tried, but didn't work: > about:config _ browser.sessionstore.restore*demand (switch) > Addon _ LoadTabOnSelect 3 (But it worked weirdly.)

Hi,

We are using firefox as the browser client for a webrtc based video streaming application. The other client is Gstreamer webrtcbin. The communication works fine with FIPS mode disabled, but it fails when we enable FIPS as part of security. The Gstreamer client sends an SDP offer to the firefox browser client, but it fails to create an answer and respond back. The WebAPI (RTCPeerConnection.createOffer) fails with below exception at application code.

"UnknownError: The operation failed for an unknown transient reason"

Also, tried to check some failure message in browser log and found as below. Not sure if it is related to the failure.

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsICryptoHash.init]

System setup:

OS - OpenSUSE 15 SP3 Firefox version - 78.13.0esr (we also tried with version 91.10.0esr)

Any quick help will be much appreciated as we are stuck with this.

Thanks, Saurav

Revision: 115.9.1esr (64-Bit) for openSUSE Leap (15.5)

Some months ago, I unfortunately typed a password in the username field of a local page (access to my Internet box, oh Noes).

Since then, it appears each time I remove the access data in the Firefox settings. When entering data again for a login without password enquiry, the password becomes invisible again, and vice-versa.

It is impossible to show the phenomenon using a screenshot, as the password immediately disappears.

I am using the Experimental API in my private Firefox extension.

So far, I've been using Firefox 102 ESR, but I'm planning to switch to Firefox ESR 115. There's already a Firefox 115 Beta available, so I've started testing it with my private extension.

So far, I've been using internal Firefox functions like `loadOneTab` and `loadURI` and it worked very well.

I used the `loadOneTab` function like this:

``` const placesURL = "chrome://browser/content/places/places.xhtml"; window.gBrowser.loadOneTab( placesURL, { inBackground: false, allowThirdPartyFixup : true, relatedToCurrent : true, triggeringPrincipal : services.scriptSecurityManager.getSystemPrincipal() } ); ```

But the `loadOneTab` function no longer exists at all in Firefox's internal API. What should I replace it with?

I found the function `_createTab`:

``` // window.gBrowser._createTab({ uriString: placesURL }); ```

But the `_createTab` function returns an error:

``` Uncaught Error: UserInteraction with id "browser.tabs.opening" was not initialized ```

...I guess this is by security to make this function called only by user action? And I call this function inside `async function`.

Is it somehow possible to open a new tab from the Experimental API in Firefox 115 beta? I need this very badly. Really very much.

---

I used the `loadURI` function like this:

``` window.gBrowser.selectedBrowser.loadURI(linkGo, {triggeringPrincipal: Services.scriptSecurityManager.getSystemPrincipal()}); ```

The `loadURI` function appears to still be available in Firefox's internal API, but returns an error like this:

``` TypeError: 'uri' member of CancelContentJSOptions is not an object. RemoteWebNavigation.sys.mjs:28:41 ```

How to overcome this error?

I just installed Firefox 107.0 on a new installation of Linux. I'm trying to get it set up to work the way I'm accustomed to, and can't figure this out. Instead of having search results show up in the current tab, I want them to open in a new tab, as they always have for me. As this works Just Fine on my desktop, I see no reason that it wouldn't work on my new laptop. If anybody here knows, please let me know.

Hello, I have a very odd problem with my firefox browser. I am running firefox 88 64bit on a 16.04 (I know...) Ubuntu. On certain websites, I have an issue with interactive content: www.leboncoin.fr will not let me login anymore (quite recent) www.decathlon.fr will have trouble displaying user comments, images, let alone placing an order Now and then websites with dynamic content and forms will not load...

I am not sure what is the link between all these but it seems related. I have tried the troubleshoot mode but it does not change anything. At the moment when I need to use these king of website I have to switch to another browser.

Thanks in advance for your help!

Hi, I develop a firefox kiosk application for an IoT device and I'm wondering what setting disables this message?

This message popped up on a release of our software which hadn't applied a policies.json file yet, is it safe to assume it will be covered by the following policy which we have on a later release?
