Firefox Community Forum

Hello,

I'd like to report an issue with a recent Firefox update.

Since one of the latest updates, the "Close all duplicate tabs" option has disappeared from the tab list menu (the menu opened via the small arrow on the right side of the tab bar). I've looked for it elsewhere in the UI and haven't been able to find it.

System info:

Firefox version: 154.0 (64-bit) Operating system: Windows 10 Professional, version 22H2 (OS build 19045.7663)

This feature is particularly important to me because I regularly keep a very large number of tabs open — often several hundred, sometimes over a thousand — and being able to close all duplicates at once was essential for managing and cleaning that up.

A couple of things make me think this may be an unintentional regression rather than a deliberate change: Mozilla's own support article on the Tab overview menu still lists "Close all duplicate tabs" as part of this exact menu, and I couldn't find any mention of its removal in the release notes for the two most recent versions (153.0.3 and 154.0). That said, I haven't found an existing bug report that matches this, so I wanted to check here first.

I'd really appreciate help with the following:

Why has this option disappeared from the tab list menu? Is this an intentional change, or a bug/regression? Has the feature simply moved somewhere else in the UI? If it's a bug, is there already a tracked report I should follow, or should I file one?

Thank you in advance for your help — this was a feature I relied on daily.

I checked my website https://angora.id https://angora.id at Mozilla Observatory and got A+ with 125 / 100 score.

I just curious how is maximum score can I get on Mozilla Observatory?

The autocomplete dropdowns for form fields have recently changed appearance, and I strongly prefer the previous, simple design.

The new version has:

• Clock icons next to autocomplete/history entries
• Much more vertical padding, making the list unnecessarily large
• Rounded "pill-shaped" highlighting when hovering over an entry

The previous autocomplete list was much more compact and clean, without the clock icons, excessive padding or rounded hover backgrounds.

Is there currently a setting, `about:config` preference or other supported way to restore the old autocomplete list appearance?

Ideally, I would like to use the previous style:

• No clock icons
• Compact rows with the previous amount of padding
• No rounded/pill-shaped hover effect
• Otherwise retain the existing autocomplete functionality

If there is no setting to restore the old appearance, could an option be added to allow users to choose between the old and new autocomplete UI?

Default homepage is yahoo. Since the update to version 149, if I do a search from yahoo, the new tab that opens with the search result is blank most of the time. I have to click reload for the search results to show up.

Is anybody else having that problem? Seems to be yahoo search specific but not 100% sure.

I have the VPN symbol in the upper right corner of my computer screen and have activated several times in the past when the circle turned green. The inactive form is still there, but it will not turn green when the pointer of my mouse is on it? What is wrong?

I use WhatsApp web with Firefox 151.0.3 on a Macbook Air. In WhatsApp web, you should be able to emoji over a message sent by someone else. One clicks on the smile icon at the side of the message, the emoji pallet appear above and select one of a handful of emojis. Since a recent update, the pallet no longer opens. It's just white space, the cursor does not change allowing you to pick one of the emojis. See screenshot. Is there a fix for this please?

I am trying to sync my computer and phone and it sends a code to my email address. but out of the 3 times I have tried I have received 2 codes but at least 20 minutes after sending so I cannot use them. I am using Thunderbird for my email

How can I stop Firefox from automatic granting sites cross-site cookie permissions (see screenshot)? The problem is that the cross-site cookie(s) granted for a site more often than not is completely unrelated to that site. This problem is very frustrating.

I have tried changing several settings in Tracking Protection but nothing has stopped Firefox from auto-granting these permissions. I have for example turned off "Fix major site issues (recommended)" but it has not changed this behavior.

Thankful for any help.

I clicked on the bookmarks icon to open one up, and there's nothing there. where did my bookmarks go? It's been a week, maybe, since I last used the bookmarks menu
