Three days ago this started happening. When I mouse over the Firefox icon on my task bar, I get a long vertical list of open tabs, the majority of which are blank. When you try to click the X (that appears on the right side of the list when you mouse over a blank space) nothing happens. In the past few days it showed a random mix of blank tabs and open tabs. Yesterday it only showed the open tabs at the top with a long list of blanks below. And today it's only showing the one tab I have active (despite having up to five tabs open before I took the picture).

Before this all started happening, it used to show large tab previews (not just text) that run horizontally along the bottom of my screen when I hover my mouse over the Firefox icon on the taskbar. Now it's just a list that goes vertically with all these blank tabs.

How to return things to normal? (tab previews horizontally without blanks)

I'm running Windows 11 Home, Version 25H2, OS build 26200.7623 and Firefox: 147.0.1 (64-bit)

Thank you, John

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

Up until now, if I search using the Wikipedia field on the menu bar, it opened in a new tab, just like using Startpage does. I've just upgraded to Fedora 43 and Firefox 146.0 (64 bit) and it's stopped doing that, although Startpage still does. How can I get that functionality back?

I lost the ability to browse using multiple tabs. I have to open multiple windows because the browser automatically goes directly to the site rather than a new tab. I've used firefox for YEARS. Must I change browsers to have this feature?

i just want to go back to how my right click worked before i hate this container feature and would like to just reopen my closed tabs with my right click i dont want to see the container bs anymore.

I have one particular tab group that stores a lot of tabs that I keep collapsed when not using them, because otherwise they clog up my tab bar. But with the new collapsed tab group preview, when I scroll along my tabs my screen will randomly flash with a full page of tabs, as there is no delay on the preview. I don't think this feature was designed with dozens of tabs with long titles in mind. The ability to have a delay on the hover effect, or preferably to disable it all together, would be much much much appreciated.

I have recently switched computers, and since it has been a while, I can't remember the setting on the 'about:config' page that I need to change to where when I open a new browser tab, it opens at the end of my list of tabs, rather than as the next tab. Thanks!

Just like the Android version of Firefox does! It opens the new tab(s), but load each tab at visit!

Desktop Firefox also does this at [History / Restore Previous Session]. All the previously opened tabs are opened again, but each of them only loads at visit.

This is I would like to have as default behaviour with newly opened tab(s) in Firefox. > Tab opens. > It hasn't loaded yet! > At visit it loads the content.

PS: I tried, but didn't work: > about:config _ browser.sessionstore.restore*demand (switch) > Addon _ LoadTabOnSelect 3 (But it worked weirdly.)

Enter (paste) the URL into the Firefox address bar → hit Enter (paste and go) → open in a new tab every time. I want this to open in the same tab. Firefox version 145.0

After i closed firefox with two windows it only restored the wrong tab and because most of the tabs were open some time ago i cant restore it from history too. Can i somehow restore them?

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.
