I've recently switched to Firefox but am finding some of the performance a bit cumbersome. I am continually being asked to hit "Send" ["To display this page, Firefox must send information ..."] when I am logging into my Outlook email or looking at my bank information. I'd rather not be "resending" these pages each time and am wondering if there is a setting.

Edition Windows 11 Pro Version 25H2 Installed on 2025-12-10 OS build 26200.8246 Serial number YX0J28CC Experience Windows Feature Experience Pack 1000.26100.297.0

Thanks, Nancy

Hello all,

I am currently testing the new VPN feature in Firefox. I Is noticed that Firefox always starts with this integrated VPN being off. I searched but I didn't find any way to have it always on when launching VPN. Is that possible?

Thanks!

When I try to use multiple desktops to arrange the opened windows, the window of Firefox is present in all of them, even the last one, which is usually totally empty (and when we drag a new window in it, a new empty desktop is created).

You can find attached screenshots of my three desktops, where Firefox appears (I blurred all info that could be sensitive, I hope I did not miss any !).

Is there a setting to unset this ?

NB: this is a duplicate of a post I made on askUbuntu, but it seems that this issue is more Firefox related than Ubuntu... And I did not manage to fix it with the answer provided there, so I'm trying my luck here !

NB2: oops, i just noticed that I inserted this question in the wrong topic (android), it seems that I cannot change that... I anyone see how to do it let me know !

Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

Due to muscle menu or not needing to think about it. Split should either be near the bottom of the context menu or you should be able to toggle it in settings. The amount of times I have gone to click a link to open in a new window only to split the view is driving me crazy.

When browsing between two screen, all my saved Firefox tabs disappeared. I have restarted my computer but they do not reload. I really need them (and have not accessed some of them in several weeks so it will be very hard to recover from history.) WHY did they go away and I do I restore them?

Hello,

At the last FF update, I discovered that I had VPN on my top status bar but what does it do?

I have v. 150.0.1 (64 bit). Also Windows 11. I live in France and the only reason to use a VPN is to watch a UK soap which I cannot watch by any other means unless it's live on the TV. I know how to turn it on (obvious), so when I use the BBC website, this is what I do. But it makes not the slightest bit of difference as I am still recognised as being outside the UK.

Am I not doing something please?

I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

I was not given a VPN setup on restarting Firefox, and have no VPN icon in my toolbar. I have tried using customise toolbar, but there is no VPN icon to add back. Version 150.0, automatically opened to "What's New in Firefox 150" on starting Firefox, just without a new VPN icon. Thanks

Updated to FF 150 today on Win 11 desktop.

Q1: Can I remove Profiles from the FF toolbar which is located in between Bookmarks and Tools? Only need one profile on this PC. I tried to customize the toolbar but it won't let me drag Profiles off.

Q2: For some reason my FF profile is now on C: even though I had previously moved it to D: to free up space on C: boot drive.

So I created a new profile with exact same folder name on my D: drive today.

In Profile Manager, I renamed the old profile on C: to "name.old and the new one on D: to "name.new". I set name.new as the default profile and it works properly after exiting and restarting FF.

Now I want to delete the .old profile but FF won't left me, saying Can’t delete a profile that is linked to other profiles. There are only the .old and .new profiles listed. So how do I unlink .old so I can delete all of it to free up space on C: ?

All my attempts to pay online with 2 out of my 3 cards have failed in the last 2 weeks. The Mastercard says it has connected to my bank and I'll get an SMS - but the SMS never arrives, and when I phoned my bank, they said they had no authorisation attempts reach them at all! The Visa card simply says it failed at the first step, without saying why or serving up the usual security dialogue. (The other Visa card just works).

I suspect the Autofill may be the problem here. I've recently had other scenarios where FF filled in a field for me, but the Javascript behind the website refused to accept it, eg saying it wasn't a valid phone no when it clearly was. The only way to get round this seems to be to type in the complete value yourself, which rather defeats the object. It could be something else, but it's clearly dependent on which software's running behind the card, as the third card succeeds.

I have lots (~100) of tabs open, distributed among windows and virtual desktops. Every now and then the laptop fan starts running wildly, and I identify a CPU hogging webpage in about:processes. How can I now switch to the open window/tab of that webpage to close or unload it? I would expect a click (or context menu item) within about:processes to bring me there. Currently I have to scan through all desktops/windows/tabs to find the page.

I am attempting to copy a FF profile from a Windows 11 machine I created it and am using it on to a brand new windows 11 machine on which I have also just installed FF on. Both machines are at FF 150.0.3. I have done a search online for the methods to do this but they have both failed for me.

The first one I tried was simply copying the profile from the existing (source) machine to the profile folder in the new machine however FF never recognized the copied profile on the new machine (I am using profile manager on both machines).

I then tried copying the profile using the method we used to use a while back to copy profiles which is to let profile manager create a new profile in the new machine, open FF so that it creates that new profile in the profiles folder then delete the contents of that profile leaving it as an empty profile (with the name of the newly created FF profile). Then, I selected and copied the *entire contents* of the source profile I was trying to copy and pasted them into the newly created profile I had just zero'ed out on the new machine so that the new profile now had the exact same contents as the source profile. I knew this copy was successful because it took a while to copy all of the data from the source profile to the new profile and the indicator showed it copying.

Again, FF did not recognize the new profile when I opened FF with the name of the new profile in the prof mgr.t.

Could someone tell me what I am doing wrong or what the problem may be? One problem I had when I first copied the source profile to my 32GB USB drive was a message saying "inbox folder is too big for destination system. " The source profile is 12.72 GB so there is plenty of room on the USB drive for it to fit. I have no idea why FF would have an inbox file so I just skipped it. The rest of the profile copied to completion once I did that but its size after copying was now only 7.65 GB, about 5 GB less than the original. Could this be my problem and if so, how do I fix it? Thanks for any help.

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

My browser was recently updated to 150.0.2, and on the new launch page after update describing new features, it prompted me that the new free mozilla vpn was available to try. When I clicked on the link to follow the steps to set it up, it said to click the vpn icon in the toolbar, but I don't see that icon there. When I go to more tools -> customize toolbar to try to find that icon to add it back, it doesn't appear among the toolbar options. Is this something I still don't have access to because it's in a limited beta, or is there some other way I should be accessing this?

Firefox updated on my macbook pro running Sequoia 15.5 but failed to restore my previously open windows. The option to restore previous session was missing. How can I get my previously open windows back, bearing in mind I'm not not a computer nerd? Thank you, Edouard.
