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.

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

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.

Regards jd

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 ?

I'm reading this> https://support.mozilla.org/en-US/kb/thunderbird-export#thunderbird:linux:tb148 Looks great but all of my messages sit on IMAP servers and I don´t need a backup of those. I _do_ need a backup of settings, passwords, pgp keys, to move to another workstation. It is unclear what exactly is exported.

I deleted a profile not knowing it would delete everything I had. How can I undo it? I didn't want Firefox Profiles, it was forced. I deleted it, and everything just got deleted. Can someone please help revert this? Thanks.

When I go to see a firefox bug such as the following, https://www.mozilla.org/en-US/security/advisories/mfsa2026-10/

There appears to be more details in https://bugzilla.mozilla.org/show_bug.cgi?id=2014390 located at the bottom. When I try to view the details it asks me to log in. I do not see any reason I should have to log in to view the issue as I only intend to view the bug. Why does it require a login ?

Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁️), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I'm running Linux (NixOS) and Firefox version 148. I've tested on Chrome based browsers and they work fine. Tested on Firefox forks and they also don't display correctly. This is new since less than a week ago.

Thanks for any help with this.

I started using Claude in the side panel instead of a dedicated tab, but there is something noise about it: every time I click to open the side panel the chat starts from scratch. Getting a clean slate is nice, but it takes too much time loading. So I would like to not unload the content of the panel when I close it, just hide it, so when I click to open is already loaded. There is a way to do that?

My old Arch Linux system with Thunderbird 145.0-1-x86_64 died. My RasPi and my new Pop-OS Meerkat both get 140.7.1esr (aarch64), and say they can't import my backups. I could see the RasPi ARM system getting a different Thunderbird, but the Meerkat is clearly an Intel processor. Why does it get the same version as the ARM based Pi? How can I recover my years of mail history? Both new installations say they are incompatible!

Firefox Sync code doesn't arrive; my email's support (Proton Mail) says you have «likely added you to their suppression (do-not-send) list automatically.».

So I request you remove the e-mail associated with my account, the one used in this post, from the do-not-send list.

Thank you.

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript

If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

When opening a new window, I get this https://hp-search.com/?path=firefox/newtab&u=7548f4ddec01b2d6&subid=11119&channel=default

I want to access an Outlook.com email. It has 2-step verification. It also says I may be missing a domain name before the email. Not sure what that is. DomainName/myemailname@outlook.com.

I need help recovering my phones my settings my photos on my accounts and passwords have been changed on two devices by a person that was not supposed to be using any of my accounts including my Mozilla
