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?)

Thanks, Marc

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.

A pop-up suggested that I use profiles to organize and it sounded like a great idea but then after making profile I was having trouble getting tabs from one page to another. Then I discovered that I had to log in my accounts onto every profile I made and it sounded like a terrible idea, so I tried deleting all my profiles to get it to revert but now that I open the browser it shows me to make a new Profile. So, I want to know how can I revert back to using Firefox Without the use of profiles like I was before clicking the pop-up

There seems to be no possible way to change the shortcut for peeking at the tabs in the sidebar (when sidebar revamp is enabled) from the about:keyboard UI. I have so far managed to modify the shortcut through intercepting function calls.

What I have done: 1. Read through the JS source code for about:keyboard which says the shortcut ID is `toggleSidebarKb` 2. Added hooks to intercept `RPMSendQuery` calls 3. Modified the shortcut through devtools open on the about:keyboard page with the following snippet

```js await RPMSendQuery("CustomKeys:ChangeKey", {

 "modifiers": "accel",
 "isValid": true,
 "key": "S",
 "shortcut": "Ctrl+S",
 "id": "toggleSidebarKb"

}) ```

The way I am doing it is definitely a hack. I am not sure if I am missing something. Although the shortcuts for bookmarks, history, and GenAI chat sidebar are present, there seems to be no entry to change the sidebar toggle shortcut itself. I'd love to work on this but I haven't been able to mach bootstrap on NixOS.

Thank you for any assistance :)

When I try to log into Tangerine bank I get the error. "We're sorry for the inconvenience. This function is currently unavailable. Please try again later."

This issue started Oct-13-2025 and it appears to work when using Firefox ESR 146.01 but not the regular Firefox 146.01 versions. Tangerine is not giving me information on the error and I was wondering if there is a difference between the ESR and regular version that might clear up this issue?

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

Back again with another question related to flightrising

there are familiars displayed next to the dragons, some of them are supposed to change their pose automatically, but for me they only change when I click on the familiar it works on other browsers, and on firefox for windows, so I guess it's something in about:config, but I have no idea what I'm doing, so I'm hoping someone here can help me figure this out, because I'm not about to mess around randomly

link to a page with a familiar that's supposed to change: https://www1.flightrising.com/dragon/80217294

pretty sure it's obvious what I mean by transform, and what I have to click on to get it to move, but I'm posting the pictures illustrating the change anyway

Using firefox 148, when I select the "CIRA Canadian shield" DNS over HTTPS option it does not work. If I select the other 2 options Cloudflare or NextDNS those options work.

What is the problem with DOH for CIRA option ?

When accessing Google Docs, I can right-click and successfully Cut and Copy from the pop-up menu, but when I attempt to right-click paste, Docs pops up the message shown in the attached image. Ctrl-V works, but clearly Google Docs understands what is being requested and simply will not perform the operation, which is very annoying. Is there any way to get Google Docs to perform the mouse-based paste?

Hello. I have issue with Firefox. I am often opening firefox by command: firefox --no-remote -P <profil> --new-window "<web_site>" Usualy it works. But sometimes it is opening new window and my web_site is located in second tab. First tab (which is completelly unwated) start loading after clicking on it. It is a recently closed tab. I call this tab zombie-tab. It was finished and properly closed, however it rose from the dead. I tried to set in about:config browser.sessionstore lot of parameter to absolutelly forbid to save any information. However, there is still whole history in the list, sites are restorable and sometimes it appears these zombie-tabs. Restore from crash is also deactivated. I tried before to start the firefox without --no-remote parameter, but AI recommend me to add it there. It did not help. Since it is happening occasionally, I consider it as a bug. Some my settings: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0 browser.sessionstore.resume_from_crash = 0 browser.sessionstore.cleanup.forget_closed_after = 149 Version: 140.7.0esr (64-bita) OS: Debian GNU/Linux 12 (bookworm) How to prevent to create zombie-tabs?
