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

This code in mozilla.cfg used to overwrite new tab, but as of latest firefox 136.0b1 no longer works. Any way to fix this? There error in Browser Console.

// mozilla.cfg needs to start with a comment line var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 var newTabURL = "file:///D:/Documents/images/home.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

im having issues with my tabs as there are now two sets of tabs one that is empty basically and seems to be treated as the main one and the other that is all my other tabs... but when i try to switch to them it switches my screen so other apps like games or messaging apps no longer are visible yet the still appear to exist

I just opened Firefox on my Win 11 pc, and find all my tabs have gone. The setting to reopen last session is active, as before. I think FF updated itself earlier today. I also had occasion to look at it briefly on my synchronised android phone. I would like to: - get my tabs back - find a way to stop this haappening (it's not the first time).

Any advice much appreciated, thanks. Richard

I have a strange problem and cannot find any reason for it.

On two different machines (with the same Firefox account, same extensions) I'm using tab groups, also in multiple windows (restoring them after launching Firefox).

In one installation I can close all tab groups without any problem.

In the other if it's the last open group, trying to close it (by clicking its header) opens a new, empty tab instead.

I'm pretty sure the settings of both installations differ but I cannot find any setting that would cause this behavior. It's especially annoying because with many open tabs I have to scroll through all to find the group I want to open instead, open it, scroll back to the other group header and close it.

Any pointers on where to start looking?

Losing my mind on this one.

Have 2 Macs I use at home, both running FF 141.0 and Sequoia 15.5.

Use Reader for RSS and Airmail for eMail. Both have settings to allow links clicked in those programs to open browser tabs in background. Handy way of banging through newsletters and RSS feeds before shifting to browser.

One on Mac, that open in battleground setting on both apps works as it has for, oh, last several years. On the other Mac, a few days ago that open in background stopped working with Firefox. It does work properly on Chrome and Safari if I set them as default browser (and, as I mentioned above, on my other Mac).

I've tried resetting Firefox on this Mac using the troubleshooting menu and have also cleared the Firefox cache. I even tried resetting the launch database in that Mac, although the fact Chrome and Safari are working fine suggests the OS isn't the culprit.

I'm unaware of having changed any settings, but am aware that "idiot user" may be the issue.

Regardless of how this happened, any ideas how to sort this annoyance out? Thanks!

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

Since the last Firefox update, I've noticed an issue whenever I launch the browser. I have it set up so that I have multiple tabs open, and it's set up so that when Firefox starts up, it opens all of the previous tabs and starts me on the tab I was on when I closed the browser previously.

Now whenever I start Firefox, it opens to the last tab I was on, but said tab opens on my current homepage instead of the website that tab was on previously. I experimented by changing my homepage to "Youtube.com", picked a different open tab, closed Firefox and opened it again and sure enough, the tab was now on the Youtube page instead of what it had been previously.

Is this just a bug of the current Firefox version, or is there something in settings I can do to fix this?

I have a fresh installation of xubuntu 24.04, with firefox 135.0. Middle clicking on links now does nothing, whereas earlier it opened the link in a new tab. browser.tabs.opentabfor.middleclick is set to true.

I use google as my default firefox home page on my HP laptop. recently a second tab opens at the same time. "how to set the home page" --I've tried closing it and restarting the laptop, but it continues to pop up every time I open firefox as a 2nd tab. I am/was happy with my homepage opening to google. How can I get rid of this second tab. thanks

Hey there, I had two windows in firefox open, one of which had a lot of tabs. I was using firefox on my surface pro, and then got up to get a snack. I came back, and the window, which I had been using for some time, was gone. The other window was still open, and firefox had not been closed. I thought I would just open it up by restoring recently closed window, but it was gone. I routinely clear my history, but even tabs that I just had open 5 minutes ago are missing from my history, like I never opened them in the first place. What is going on?

Previously, I was able to click on an image in a page, then it would appear below that pre-click. Then, if I wanted to view the image link, it would open that link in a new tab. Now, for some reason, when I try to click to the new location, it opens it in my existing tab, rather than a new tab. How can I fix that?

I seem to have accidentally set up tab-groups, on desktop. Probably I fat-fingered a shortcut to group some tabs. This is a function I'll never intentionally use — since I'd rather not cut off my fat fingers, is there a way to permanently shut off tab-groups?

Thank you kindly.

Hello, I closed my browser, expecting it to save my current tabs as it usually does. When I reopened it, the tabs were gone. They were important for me, and some of them were pretty old so I can't find them in my history. I tried checking the "recently closed tabs" option, it didn't help. There was also no option to restore the previous session. Can you help me restore my lost tabs?

Windows 10, latest version.

I hit a shortcut, I think, and heard the trackpad, then one of the three open tabs was isolated from the rest in a separate, almost chromeless window.

It's not in the taskbar pop-ups but instead has its own icon. In this 'chromeless' window there is no option to add a tab or window, there is no area to move it (I have to carefully use emtpy space in between buttons to move it). The top just fell off, that's basically it.

I have never seen this and have been using Firefox from the start way back when. I didn't install anything; this just happened as I was reading something and accidentally touched a key. Nothing changed, no settings were adjusted, nothing.

This option is not in the tabs menu or anywhere. I must say I kinda like it for this one 'tab' (which is a solo chromeless window) but I do need the menu and so on for productivity.

One of the screenshots shows this 'window', the other shows that 'window' is not part of the regular pop-up tabs in the taskbar but rather has its own icon, as if it were an app, in that taskbar.

What in the world is this? Can someone help?

Recently updated to Windows 11 after Windows 10 stopped getting supported. After putting down several smaller issues on my own, I can encountered something I cannot fix on my own. Currently, I cannot detach, reattach, move tabs (With the exception of moving tabs with the right click menu). I could do all of these on Windows 10. I have already tried the browser.tabs.allowTabDetach setting in about:config to no success. I am starting to suspect it is a problem with windows versus a problem with Firefox because of an earlier bug where I couldn't move the windows entirely without enabling the Snap Windows function in my settings.

I am using Ubuntu 22.04. Firefox version is 143.0. IIRC firefox recently updated. I have the setting "Open previous windows and tabs" checked. Until very recently it has always worked but now when Firefox is closed all tabs are lost and don't appear when reopening Firefox. How to fix???

Please see this video. Double-clicking can only close the foreground tab. If I double-click the background tab, it will become the foreground tab, and double-clicking it multiple times in a short period of time will not close it. I have to wait about one second after stopping clicking the left mouse button before I can double-click it again to close it. Some Chromium-based browsers do not have this issue, and each of their tabs can be closed by double-clicking I can only show it with video. Please leave a message if you can't see the video.
