After clearing Browsing data, therefore Loging out of twitch etc., i now constantly get the error "Browser not supported" on attempted login

Other Browsers (Chrome) work fine and ive already tried deleting Extensions and reinstalling the Browser to no avail

here's the error messages that come up

any help would be appreciated

I have had this problem in the past, but now its back again. At first I just reset my password every time, then I set up the password to be auto-filled. I have had no sign-in failures for months. At one point i did figure out how to check my sign in history to see the failed attempts, and there were none. That was a long time ago, and I have since forgotten how to check this. The problem does seem to be with firefox as it does not happen with chrome.

• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

Occurs since end February, so probably since 148.0-1 Always in the same place in libgio-2.0.so.0

I will try to roll back to 147.0.4-1

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike

I don't plan to use any provided AI chatbot. I want to use models that I have downloaded and tested myself and which run on my PC. So please add the possibility to connect through major LLM APIs, the same way other tools way simpler than Firefox already allow to do.

Listen I have a profile in another partition in Mint and want to transfer my Bookmarks/profile etc to my new 22.3 install but far too complicated. I also have a previous Key which I no longer wish to use as it has deleted all 20 years worth of messages. Please please please just set up my profile again oFirefox or then revert by to the one from 2025 Mint 21.3 Thomas McM Rbold textamos de Deus

Firefox worked this morning, but stopped in the afternoon. I ran an update, but could not connect to my gmail account anymore, or listen to the Radio France podcasts All this works from Google Chrome (not my default browser). All under the Mozilla VPN 2001:4860:7:150e::fc (why the IPv6 address?)

I noted, that credit cards autofill works, but on ~50% of websites it fails. I can see the autofill dropdown, but if I select any card, no fields are filled. Manual filling works. One of examples: https://ipn.paymentus.com, but there are many. Again, on some websites it works just fine.

Another issue - I cannot edit cards. Settings->Payment methods->Manage, then select a card, press "Edit" and nothing happens.

Context: version 148.0 (64-bit), Canonical snap build (crap, I cannot DISABLE snap build and totally switch to deb!!!)

P.S. I really miss feature to add "aliases" for cards...

Subject: Request for Custom Provider Support or Grok Integration in Firefox AI Chatbot Sidebar

Detailed Description: I am exploring the new AI Chatbot sidebar feature in Firefox (Ubuntu build). As a practitioner in the deep learning field, I am particularly interested in the flexibility of the Web-view container used for these AI integrations.

Currently, the feature appears to be a curated list of providers (ChatGPT, Claude, Gemini). I would like to request the addition of Grok (by xAI), or more importantly, a Generic Provider Framework that allows users to manually configure custom endpoints.

Technical Specifics & Implementation Questions:

   Manifest Configuration: Is the sidebar AI provider list controlled via a remote settings push, or is there a local about:config or JSON manifest (e.g., within the browser resources) that can be modified to include Grok's web URL?

   Context Injection: How does the current sidebar handle DOM context for features like "Summarize this page"? If I were to manually add Grok via a side-loading method, what are the required API hooks for it to achieve parity with the built-in providers?

   User Agent & Authentication: Are there specific CORS policies or User-Agent strings enforced within the sidebar's iframe/browser-view that would prevent Grok’s X-auth or real-time streaming (SSE) from functioning correctly?

Use Case: Integrating Grok’s real-time information retrieval directly into the browser’s native sidebar would significantly optimize research workflows involving live data, which is a key differentiator from the currently supported models.

hello,

I want to transfer my profile from an old laptop to a new one. i am not comfortable with uploading my passwords to the cloud as i do not understand how this is safe. i made tar.gz file with the entire profile, almost 1gb and put that on the new laptop. edited the profiles.ini and install.ini and expected the profile will load, but firefox simply does not work in that profile. it cannot browse and clicking the menu button in top right does nothing. Please, help. If I share data below that is the working profile, not the one that fails.

Hello,

Can you please help with the following scenario.

Both, a Firefox sync master account and Firefox Relay extension are active when running the browser.

So, is it possible to change the master email addresses of both features (+ secondary email) ? I would like to use a new email address for authenticating in both features of Mozilla, but do not want to set up new accounts.

How can I do that in Firefox Sync and Relay?

Thanks for your support.

I am using Debian Trixie with firefox 148 and I reported that the refresh option was missing from Firefox, https://support.mozilla.org/en-US/questions/1569549. I then noticed another workstation with the same version of FF that did not have the "refresh firefox" option.

It appears firefox has been changed. Some of the items have been changed including the profiles option to add color on creation.

How can the parameters of FF be changed ? See enclosed menu under help, "more trouble shooting information", you will see "refresh firefox" is missing from the top right.

Using 148 on Debian trixie I do not see the option for "refresh browser"?

https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

Does it still exist or is there an alternative ?

This setting, "Always ask you where to save files," is definitely broken.

In a related article, they provided this solution: https://support.mozilla.org/en-US/que.../1534384 https://support.mozilla.org/en-US/questions/1534384]

Proposed solution: "I believe you also need to go into Tools -> Settings -> General and set the Action for the types of downloads (Applications) to Always Ask for those types you want it to."

But this workaround should not be needed. "Always ask" means always ask. As in always. No other additional steps should be needed.

Can you folks please open a bug to get this fixed? This used to work just fine in (much) older versions of Firefox and Netscape. "Always ask" is supposed to mean always ask. Like, always.

When I'm on a site that I've accessed on my main machine or phone (Apple), but try to use my Apple ID when logging on via the Firefox browser on my Linux machine, I get a popup asking for a fingerprint. None of my devices use a fingerprint. I get it needs confirmation, but very rarely you get the dotty circle to use with your phone camera, but not all the time. How can I make my life easier and get the dotty circle all the time, or force things to go to my phone for confirmation that it's me - face ID or something.

I've looked on my Apple stuff and can't find anything that will help, so I'm reaching out!

I've been trying to decipher browser.tabs.insertXXX with little success. What I want to achieve is to open tabs from the same site next to the current tab with the most recently opened tab next to the original tab.

Example Two tabs are open, site 1 tab 1 and site 2 tab 1. Open a new link to site 1 on site 1 tab 1. The order is site 1 tab 1, site 1 tab 2, site 2 tab1. Open another link to site 1 on site 1 tab 1. The order is now site 1 tab 1, site 1 tab 3, site 1 tab 2, site 2 tab 1.

Thanks in advance.
