Hello

I just activated the Mozilla built-in VPN (beta).

I wanted to ask about the whitelist and blacklist features.

I can see currently, that there is an option to add specific websites in the VPN settings, and that the tooltip says "Use VPN for all websites except the ones on the list", acting as sort of a whitelist for the VPN features.

However, I am wondering if there is an option for a blacklist, where i would like to keep VPN off by default for all websites, except the ones on the blacklist.

For a simple example: wowhead.com is blocked in my country of origin, so I would love if i can turn on the VPN for ONLY that website - and keep the rest of my traffic on other websites without the vpn.

Settings->Passwords and autofill->Manage payment methods Only gives me the option to "Add new payment method". I can fill that out, but cannot save it.

I have an old credit card saved that I cannot update, change, or get rid of. That number was replaced with a new one, so it's not even valid anymore.

I followed the recommendation under the help file to check "Privacy and security->History", and it's set to "Remember history", so that shouldn't be a problem.

I was having this problem on my previous Windows 10 laptop - after transferring everything to the new one that's running Arch Linux, it's still the same. I'd really like to fix it, thanks.

Hello AMO team,

I am the developer of two add-ons published from my old account, which I can no longer access: I lost the authenticator app used for two-step authentication, and I have no backup authentication codes or account recovery key for that account. Password reset is therefore impossible (the reset flow requires a TOTP code, and no recovery key exists on the account).

I would like to request an official transfer of ownership of the following two add-ons from the old account to my new account:

1. Admin-panel quick access - https://addons.mozilla.org/addon/admin-panel-quick-access/ (add-on id 2650700, guid {dc8766bb-be8a-4bf9-aec8-6bf114d6ed24}) 2. TripleKeep - https://addons.mozilla.org/addon/triplekeep/ (add-on id 2654061, guid {ddb290f5-c226-4a22-9dd0-b1731169d15b})

- Old account: https://addons.mozilla.org/en-US/firefox/user/15677483/ ("Shepel", registered 2020-02-19) - New account: https://addons.mozilla.org/en-US/firefox/user/17480927/ ("Shepel Pavel", email [redacted] @mail.ru)

Proof of ownership:

- The support email listed on BOTH add-on listings is [redacted] @shepel.net - an email I control and have full access to. I can reply to any verification message sent to that address. - Both listings link to my GitHub repositories, which I still control: https://github.com/shepelpavel/go-to-admin (branch firefox) and https://github.com/shepelpavel/triple-keep (branch firefox_ver). - The manifests in those repositories match the published versions exactly: "Go To Admin" version 1.3 (= published version 1.3 of admin-panel-quick-access) and "TripleKeep" version 1.4 (= published version 1.4 of triplekeep). - Commit history in those repos (author [redacted] @gmail.com, dated 2020) matches the AMO submission dates (2020-07-02 / 2020-07-23 / 2020-08-11).

I have intentionally not re-uploaded these add-ons under the new account to avoid GUID conflicts - I am requesting an official ownership transfer instead.

Please let me know if you need any additional verification. Thank you!

Best regards, Pavel Shepel [redacted] @shepel.net

Hi I noticed that some old links in my history are automatically deleted. How to configure expiration rules (if possible) in order to keep links forever, until manual deletion? I know that links can be saved in the bookmarks, but when browsing the Internet, unless bookmarking everything :(, no one knows if a link can be useful in the future.

Thanks for your help

System: Linux Mint 22.3 Xfce Firefox web-browser: mint-001 - 1.0 _ 155.0.1 (64-bit) Hardware: Both on my Desktop and Laptop computers.

Since the recent updates, 1-2 weeks, every time I try to enter a character via Unicode insertion, CTRL+ALT+U, the character does not insert but a row break. I made a video about it: https://youtu.be/OP9UCGpZdEc

This happens in every website I use; mostly likely on every website.

Is there anything I can do now?

Thank you for your time reading this. 🙇

About a month or so, opening tabs changed. It's more annoying and less convenient now for no clear reason.

Before, when I opened 20 links in new tabs, the existing tabs were pushed to the left. Now, the new tabs disappear to the right, and I need to scroll the tabs list to see them.

This makes researching things annoying. Especially when I'm trying to find anything useful among tons of useless search results. Normally, I would see every tab that I opened. I could always instantly see by the number of open tabs and domains if I should continue the search. No tabs? I haven't found enough. Same domain? I'm probably running in circles.

To replicate this workflow, now I'd have to manually scroll every time I open a new tab, which would be mighty annoying.

Meanwhile, there's no advantage to seeing my old tabs rather than new tabs. The new tabs are always more important in the moment because I just opened them.

Can this be changed back to old behaviour in about:config, or by some arcane profile hacking?

Noticed in LM, the last couple Tbird versions, the context menu doesn't close, when click anywhere on active window, away from the context menu. Happens if R click a message in thread pane, or pretty much anywhere else that R clicking opens a menu.

• Only* hitting Esc key closes it.

Could be a profile issue? (but isn't due to theme used in Tbird - tested several, incl. native w/ Tb package).

Normally, opening a context menu, then L clicking anywhere inside the active window, closes the context menu (how it works in Firefox).

Also, opening a context in Tbird (if don't close it), switch to another app, the Tbird context menu shows on top that app.

I do all my email on my computer but I do have Tbird on my cellphone too, just in case I have to send something. But I never download. So I was in a situation where a government process included 'check your email' and I had only my cellphone with me. So I started downloading: 25 more, 25 more, 25 more ... and a hundred presses latter it's still not finished. Is there some way to reset that? I'm back with my computer and my email seem fine, but the cellphone remains stuck.

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

I just recently installed the VPN on Firefox. It hadn't shown up because of my privacy settings. It works fine except for the United States connection. When I choose the other countries, it works fine, but when I choose United States, it still shows Japan (where I live). It still shows Japan, but it does have an effect. It changes it to Tokyo, where I don't live. So, the vpn is having some effect, but it is just not connecting to the United States. Why is that?

Hello all, thank you in advance for your time. I've got a Lenovo running Linux (Zorin, an Ubuntu branch)

Crashes have been more and more frequent over the last couple weeks. Usually it closes only Firefox, sometimes it throws me back to the login screen, and rarely the computer crashes entirely. I've been trying to pin down the source of the crashes -- it hasn't only been Firefox, but most of the crashes are while FF is open.

THIS tab keeps crashing, as I type.

It seems to happen more often when I'm watching video.

Here are all the crash IDs within the last 24 hours: bp-dfb0bd40-4ce6-41bd-b9cb-ad0510260913 13/09/2026, 11:15 View bp-50a8400a-3439-4af4-b5c7-6e60f0260913 13/09/2026, 11:15 View bp-0893e979-6a06-40cc-ad0b-757210260913 13/09/2026, 11:15 View bp-8a1bbc36-9c1d-412c-a2cf-c4c040260913 13/09/2026, 11:15 View bp-4c97e699-dee7-470f-9f82-855760260913 13/09/2026, 11:15 View bp-4526b2af-908a-45be-89ae-293ef0260913 13/09/2026, 11:08 View bp-60af27d7-aeef-4761-b86e-7595a0260913 13/09/2026, 11:08 View bp-25b42dd1-3f54-4be4-bde7-801f60260913 13/09/2026, 11:08 View bp-e92ad4f9-b7d3-453e-8c5a-066910260913 13/09/2026, 11:08 View bp-d19f0c4c-9eb7-45d1-a7e7-978d90260913 13/09/2026, 11:08 View bp-b212719f-1daa-459c-8491-2c6cb0260913 13/09/2026, 11:08 View bp-9effc3ad-0b73-43d2-839c-805a00260913 13/09/2026, 11:08 View bp-7e5b6de1-7a84-48ad-86c0-e07510260913 13/09/2026, 11:08 View bp-271c4c4f-9f81-480a-9815-5f5bf0260913 13/09/2026, 11:08 View bp-956cef3e-25a1-4a8c-b7e1-668be0260913 13/09/2026, 11:08 View bp-92a596e6-edc8-4920-9365-6e3e00260913 13/09/2026, 11:08 View bp-6e309137-bf0a-4ee1-8ddf-492b20260913 13/09/2026, 11:08 View bp-d3eadcae-1967-4c31-856f-284f80260913 13/09/2026, 11:08 View bp-e319008d-d7e3-4354-95db-846e10260913 13/09/2026, 11:08 View bp-ce80cf98-4aad-46ee-a2a2-40ccf0260913 13/09/2026, 11:08 View bp-41734b4e-09d0-4dfe-ab7a-c74400260913 13/09/2026, 11:08 View bp-37752c09-a2ae-4f35-8ee6-62ee60260913 13/09/2026, 11:08 View bp-01aed5a5-d3da-4551-9646-eb73d0260913 13/09/2026, 11:08 View bp-0d52d173-f46d-4d5c-b723-441930260913 13/09/2026, 11:08 View bp-5a9507dd-21f3-4be3-8d68-ad70f0260913 13/09/2026, 11:08 View bp-0a5b5b7c-6400-41f7-ba67-c881b0260913 13/09/2026, 11:08 View bp-2ff2f687-e231-4ac5-925a-fde060260913 13/09/2026, 11:08 View bp-1c9a1836-3ebe-40bd-ac76-182850260913 13/09/2026, 11:08 View bp-f4bbc332-be5c-48f7-8e6e-c008a0260913 13/09/2026, 11:08 View bp-807e438c-9bb1-4056-b67b-48e870260913 13/09/2026, 11:08 View bp-b422a84c-4096-4ab8-926c-d63030260913 13/09/2026, 11:08 View bp-9740f00f-a1ac-4fce-96b3-704940260913 13/09/2026, 11:08 View bp-0a571a75-602f-4802-98df-22ee30260913 13/09/2026, 11:08 View bp-5f7a41ac-f92a-42b3-96bc-6dda70260913 13/09/2026, 11:08 View bp-d81a88f6-3da4-4e15-8669-352390260913 13/09/2026, 11:08 View bp-324a6102-496b-4724-9deb-3532f0260913 13/09/2026, 11:08 View bp-40969791-0669-4158-abd6-b57230260913 13/09/2026, 11:08 View bp-7b5c8e37-6cfe-4027-9bd1-fc0d80260913 13/09/2026, 11:08 View bp-62dbac62-1feb-47a6-be53-bd8b10260913 13/09/2026, 11:08 View bp-9197029c-0719-4294-bc37-e7f320260913 13/09/2026, 11:08 View bp-941d7f54-5b2e-4783-83f2-66c330260913 13/09/2026, 11:08 View bp-00202476-8680-4295-8a76-a97db0260913 13/09/2026, 11:08 View bp-027dfa8e-f3e1-44e9-a405-1ae350260913 13/09/2026, 11:08 View bp-369f58c9-4456-4578-977e-49cfe0260913 13/09/2026, 11:08 View bp-78c25147-3a9c-4ad8-9210-eb0ca0260913 13/09/2026, 11:07 View bp-f1f4b2b3-0885-4259-8dd3-bfa700260913 13/09/2026, 11:07 View bp-72d20621-92ea-417a-b063-deba40260913 13/09/2026, 11:07 View bp-721a4c72-ab3c-4ea0-8428-72b6d0260913 13/09/2026, 11:07 View bp-ffb02689-cb96-48e2-ab89-1c7f10260913 13/09/2026, 11:07 View bp-407b7ac2-8d4c-404d-974a-96d790260912 13/09/2026, 0:37 View bp-9decd8ef-b380-4bfe-8264-6841b0260911 11/09/2026, 22:40 View bp-c9a8eae8-8723-48ba-aab0-48db10260908 08/09/2026, 22:57 View bp-e0ac525c-a6c7-4af5-abe8-0ab5e0260913 13/09/2026, 11:16 View bp-91be494d-2e41-42b7-9330-e49630260913

I have the latest T-bird installed on a latest version linux Mint laptop and occasionally get puzzling errors on Yahoo mail.

Mostly it all works, but Yahoo email errors are often enough to be bothersome and I can't find any information on the rather obsure errors. Been this way through many t-bird and Linux releases.

My other email accounts don't seem to have a problem (gmail, outlook) on any t-bird instances. Just Yahoo mail on Linux Mint t-bird. Here are the errors:

"Please try later" and apparent timeouts on Yahoo mail (on t-bird, of course). This is obvious, but it doesn't happen on my Win 11 and Android T-bird programs.

Operation on yahoo "inbox" did not succeed. Yahoo mail server responded "p." (Yes, just "p.")

Operation on yahoo "inbox" did not succeed. Yahoo mail server responded "UID FETCH completed"

These errors don't seem to happen on Android t-bird or Win 11 t-bird on the same accounts, but I'm not on those for very long.

Any guidance would be appreciated.

Yes, this outlook account was made earlier this year. I've tried all of the "fixes" offered on here and across the internet. I'm changed to to password and got the app password. I've deleted 2FA to see if that would work. I've deleted the Oauth key and it refreshed to a new one. I've done it all and TB-sync is not available to me cus apparently now i'm right outside the app version limit.... how convenient. It's very frustrating as i really like the app and still use it to read my emails but it's very annoying to have to open the outlook app and go through all that just to send an email. I keep getting told it is possible, i've been battling this on and off for months. I cant just get a new email either as i already swapped everything to the outlook one and my work using out look as well. i am able to sync my calendar even but apparently just not my outgoing emails. I would like to transfer my email but the other email i have is a proton email and they are a whole other headache. Please help.

I have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

Hi,

I'm using Firefox 155.0.1 64bits, in Linux Mint Debian Edition 7, x11, XFCE4. I have a Belgian keyboard. I have noticed that the dead keys aren't working any more when typing text / messages from within Firefox. I don't have this problem in other browsers or applications.

I used xev (x11 utility) to check if the dead keys were working and tested a different keyboard, all work. I tried to start Firefox in safe mode or by starting Firefox from a terminal with the following commands: - env GTK_IM_MODULE=xim firefox - env GTK_IM_MODULE=ibus firefox

But nothing worked. The dead keys aren't working. The issue must come from Firefox for it is not an hardware issue (tried different keyboards) nor software (dead keys work in other applications).

Any idea to fix this ?
