Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.

Taskbar doesn't appear on hover in Firefox 141/142 when taskbar auto-hide is enabled (Windows 10)

Sorry for my language.

The latest versions of Firefox 141 (and 142 beta 1) do not allow the Windows taskbar to appear when I move the mouse to the bottom of the screen. This happens on Windows 10 with the auto-hide taskbar setting enabled. In previous Firefox versions, this worked fine (except for one older version where it briefly broke). I’m not running Firefox in fullscreen mode, and I have no modifications or themes that could interfere. I tested this on a fresh, clean installation of Firefox — the issue still occurs. After downgrading to versions 140 and 139, everything works correctly again. Interestingly, I also tested the Firefox 141 Release Candidate Build 1 from here: 🔗 https://ftp.mozilla.org/pub/firefox/candidates/141.0-candidates/ In that version, the issue only occurred in private browsing mode. Could someone please help me resolve this or confirm it as a bug? Thanks in advance!

Since version 148.0b2 (64-bit), it's once again not possible to enter search terms in the search box of a new tab; instead, the browser searches in the address bar. I've had all the settings I found in the forums configured correctly for over five years, and they haven't changed. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Despite this, the search still occurs in the address bar. Now I'm back to the awful search in the address bar. How can I fix this? Please fix this bug as soon as possible.

Original: Set der Version 148.0b2 (64-Bit) ist es wieder nicht möglich die Suche im neuen Tap, im Suchfenster einzugeben, sonder es wird wieder im Adressfeld gesucht. Ich habe alle Einstellungen, die ich in den Foren gefunden habe schon über 5 Jahre so eingestelle, sie sind auch nicht geändert. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Trotzdem wird die Suche im Adressfeld geführt.

Jetzt geht es aber wieder mit der Schrecklichen suchen in der Adresszeile los. Wie kann ich dies ändern? Bitte diesen Fehler (Bug) schnellst möglich beheben.

No reply needed, buy that needs a fix. how could that ever pass QA.

When signing in to websites, firefox offers e-mail address options that havebeen used before on that site. But right now it keeps offering two, one of which is incorrect, and I thought there was a way to fix that, but right now I cannot remember it.

This is explicitly for sites where I have told firefox *not* to save the password, and it is offering up potential email/login. entries *only*.

I do not want to tell firefox to not offer to autofill anything ever, because that saves time when the entries are correct. but here they are *not* correct and I need to clear them for this one specific website.

How do I do that?

Сегодня 23.04.2026, я открываю браузер и вижу, что моя строка и ярлыки находятся сверху, а не в центре(1 скриншот). Вчера 22.04.2026 все было хорошо, я покажу на 2 скрине как это должно выглядеть. Хочу заметить что у меня включена функция Handoff и она мне удобна, но мне неприятно видеть блок с ярлыками и строкой не по центру. Я использую тему ffultima, скажу еще раз, вчера все было нормально.

Hello everyone,

I have a problem. I have seen that there have been discussions about this in the past. Unfortunately I have not found a solution and the discussions are all archived.

Now to the problem: Various pages have no favicon in Firefox when I drag them into the bookmark bar as a bookmark. However, when the page is active in the tab, a favicon is visible there.

The problem does not seem to be unique to me. Several people have tested it. It also seems to be a problem in Firefox only. In other browsers, this problem does not occur.

What can website owners do to fix this problem?

Here is an example of a site where I have the problem. www.organspende-register.de

Many thanks in advance. Best regards
