On Firefox I have repeatedly pinned four tabs for websites that I use frequently. The pinned tabs disappear at unpredictable times, not necessarily when I re-open Firefox.

I want the multiple tabs back at the top. I haven't been able to follow any directions online because either I don't know what words/places are, or the place I'm supposed to click on doesn't exist. I'm using Chrome at the moment, but would like to go back to Firefox if there is an easy fix.

When i downloaded the app, it automatically came with the ability to group tabs, but after i customized several settings it took all of my tabs out of the groups and i can't group them anymore. The settings i changed ranged from privacy to personalization, i tried to reverse some of them to see if that would help and did a bunch of back and forth, but it's still not coming back. (Im trying to leave chrome because i noticed it had some very concerning lack of privacy settings that messed with my phone's ability to function properly if i turned them off. And Edge is worse.) Firefox seems better, but without the group tabs option it makes it waaaay too ridiculous to try and do any real work with it. I do a lot of multitasking and research and need to be able to bounce around and organize stuff. Your help stuff on tab groups doesnt say anything about how to turn it on or off. So... how do i get it back?

Today after i restarted my laptop (windows) and then I started firefox all the pinned and also the normal tabs were gone. I tried to follow different indications about restoring the previous session, but nothing showed up. All the tabs are gone.

As I need these tabs and this is obviously an issue of the software, PLEASE FIX THIS ASAP.

Is not possible that this happens every 1-2 months.

I'm using Windowa 11. When I click on a link I want it to open in a fresh tab/page, but it opens on the current page instead. Firefox used to do this: how can I set it up again?

In Settings I have checked the box to open previous windows and tabs and yet it doesn't open any of them .

This started happening after a ran a Norton Cleanup session. are there some Mozilla files I need to delete to reinitialize them

In Firefox 152.0.5 under Windows 10, when I hover the mouse pointer over a tab, a balloon pops up showing the text that is on the tab. I find this extremely annoying as I can read what is on the tab. I have searched on the Mozilla site, and I have searched with Google, all to no avail. How can I disable those redundant popup balloons?

I have Firefox Focus set as default browser on my Android phone. When it is used as Custom Tab, it cannot handle opening URL that is supposed to be opened in a new tab and did nothing instead.

My use case is, opening a link from Telegram message, the webpage is opened and is rendered in Custom Tab. Click on a link that is supposed to be open in new tab. Expectation is the new page will be opened, but it's currently doing nothing.

Is there anyone experiencing the same?

Hi all,

Sometimes Firefox just closes a couple dozens tabs - I keep around 200 or 300 open - without my request or confirmation. It's not frequent, but quite annoying. Clicking History > Recently closed tabs > Reopen all tabs does not restore all. I don't know where I can find references for the lost tabs or Firefox logs where I could check what happened. My only suspicion is that I inadvertently rest my hand or finger somewhere in my notebook's trackpad, and somehow Firefox understand that as a request to close several tabs at once, but I have no clue if that makes any sense. I didn't test in Safe Mode because this happens too unfrequently for me to tell if Safe Mode avoids the problem.

Could you pls help me finding the reason for that? Does Firefox keep any kind of log I can check? Are there any keboard shortcuts or mouse/trackpad action that can be set up to do this?

Firefox version: 153.0.1 Distro: Linux Mint Version: 21.3 (Virginia) (Based on Ubuntu 22.04 - Jammy) Kernel: 5.15.0-186-generic

Thanks!

Hello, I would like to suggest adding an option to open dragged links into Firefox window as new tab. At the moment it can be done through dragging link onto tab bar in between tabs, but due to small space, this can easily result in dragging link onto page tab.

Currently, when dragging link onto opened page, it will change the current page instead of opening new tab, which can result in loss of data or important information.

I think it would be safer to have this behavior as default or at least an option to set it active.

In below thread, there's an example of currently only way to open link in new tab. https://support.mozilla.org/en-US/questions/972343

I've used Firefox for years, but lately, on start-up each day, all my previous tabs have disappeared and I have to start again opening them all individually before I can start work? I thought I'd solved this in the past when I had the problem, but it's back! Help please.

I just found out that my tabs are not stored when reopening Firefox. Only pinned ones are still available. In settings of course I have `Remember history` and `Open previous windows and tabs`... I'm new to Apple, but this behaviour is absurd. Someone said I woudl have to use Command+Q as a solution? That can't be true. Is there some strange way of installation of Firefox I did that only not pinned tabs are not remembered? I have all things up to date. I'm not a noob in computer science so I can verify something more but this out of the box bad behaviour is shock to me. At the same time on Windows I have 200+ opened tabs and no problem to restart Firefox and keep have them.

Hello,

Since several months I had the experience that when I open a new tap, all my open taps, sometimes perhaps 25, are completely gone. Spend a lot of time in search and then I lose everything. Did not find a way to restore, sometimes I could. How it happens and how to do? It is more or less from the time that there is a special sign left from my toolbar and since that sign is there very strange things are happening. Is there a solution for it. Since this sign is there evrything becomes complicated. Thanks for hel in advance. Theo

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.
