Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/10.0 WWW-Authenticate: Negotiate X-Powered-By: ASP.NET Date: Mon, 25 May 2026 08:15:41 GMT Content-Length: 0

A client of ours has recently raised an issue with with us stating where right-click, Paste does not work when adding text to a new LinkedIn post

After investigating, we have been able to reproduce the same behavior on our devices.

However, from our testing, we can right click to past on comments, messages and searches just fine

Troubleshooting already attempted:

Cleared Firefox cache Performed Firefox refresh Tested across multiple devices

We have confirmed this occurs on:

Clients device My work desktop My work laptop My personal desktop My Personal Macbook

This issue appears to have started after updating to Firefox version 151.0.0. I know this as i have tested this on my work laptop, appeared to work fine then stopped working after manually updating from 150.0.3 to 151.0.0.

Please let us know if there are any known issues, additional troubleshooting steps, or if further diagnostic information would help I have attached screenshots of the issue.

I have also tested this in the Google Chrome web browser and appears to be working correctly as also seen in the screenshots.

when accessing websites where Cloudfare is part of the sequence the page hangs on cloudfare and the page is not displayed. Every time data is transferred through cloudfare the page hangs on cloudfare rending the search useless.

Since last update...the reaction emojis on Facebook are blacked out. The entire bar of emojis are not visible. It is all black. Yet the words are visible when hovered over. There seems to be nothing wrong with the FB site and it has been suggested it could be the browser. So if you have any reports of glitches like this ...would be nice if you could fix. Screenshot Impossible to take. Thanks

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.

I cannot get the free VPN to turn on. It keeps looping me back to sign in and then tells me to turn it on and then it loops back to the sign in and continues to loop

Hello, a recurring problem that's been bothering me for several months is driving me crazy, causing me to use Firefox less and less.

I regularly get the dreaded message "Error: Platform version xxx is not compatible with xxxx," which seems to have been around for years and still hasn't been fixed. Rebooting, reinstalling, or repairing the installation with every automatic update isn't a solution; it's just a nuisance.

Since dawn of times I'm using Firefox with a search box in the center of my Home page for new tabs and windows. It is the most important tool in my life as a web content manager. A few years ago my searches suddenly started to jump to the URL bar as soon as I started typing. An URL bar is - as the says - for URL's and it sits way at the top of my 27" and 32" screens, where my focus is not.

Luckily, this forum saved me with the about:config setting browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar > false to save my life.

A few months ago this was broken by 148.something. After about a month in hell that was repaired with a dot release. And now (151.0.3, Windows 11) it's broken again:

In normal mode it still works as expected, but the search box is not in the center anymore, it has been moved up to about 300 px from the top. Fixed, independent from window size !?! If you make the window small it moves out sight eventually.

In Private Windows it is still in the center vertically, but browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar > false does not seem to work there. As soon as I start typing it jumps to the address bar.

Firefox Developer Edition 85.0b4, macOS 10.15

If I Google for a PDF and click a link, I get the Firefox download dialog. If I select "Open with Firefox [Developer Edition]", the following things happen:

   The PDF is downloaded to ~/Downloads
   The PDF is opened in a new tab, with that new tab's location bar holding a file:///... URL to the downloaded PDF 

What I would instead like to happen is:

   The PDF is downloaded to some temporary directory where I won't have to worry about deleting it manually
   In whatever tab the PDF is displayed in, the location bar contains the URL where the PDF was (temporarily!) downloaded from 

How can I achieve this?

Not having the URL where a PDF was opened from is very annoying when, for example, I open a bunch of PDF search results to read and review, and I later want to share links to some of those PDFs. Best I can do to find their URLs to give to others is then to try and remember which tab corresponds to which search result, or do mine the downloads tab.

Contrast this with Chrome: I click a Google result for a PDF and the PDF just opens in the current tab with the URL to the PDF in the location bar. No dialogs, no PDF files hanging around in my home directory, and I can just copy the URL to the PDF the same way I'd copy the URL to any web page.

Thank you!

Sigh. It appears the problem was one or both of the following preferences:

   pdfjs.enabledCache.state: false
   pdfjs.migrationVersion: 2 

I deleted both, and now clicking on a PDF just opens in the sane, normal way in Firefox that I desire.

Naturally I have no idea how those got set.

Hi, I use Firefox all of the time, and I noticed that the wallpapers were given an update of more choices for the user.

That's good and all, but I began thinking about the widgets that are optional when customizing your default Firefox home/new tab. Weather, shortcuts, and stories. All very simple, rudimentary uses, but nothing for fun, like, say, a little Firefox fox that can live at the bottom of your home browser!

Like something akin to a Pou or a Tamagotchi, With food and water on one side of the bottom of your home, bed in the middle, and a little hamster wheel for it to run on. You could click on it and it plays a little animation, or you can click and drag it to either activity previously mentioned and watch it interact.

I just think it'd be fun to have a more "silly" widget for customization on our home pages, while being entirely toggle-able like the other additions.

Thanks for reading.

With love, Paytzilla

I have a document that allows me to extend the page for supporting information. However when I move the up/down bar the original document moves but there is no way to move up/down the supporting page.

I installed Firefox Developer Edition and I am having the following issues, whenever I go to Indeed and I go to a job posting the browser opens up additional tabs without my permission or me doing so. Also the browser does the same in Canvas when I go to my course the browser automatically opens up new tabs without my permission and also me doing so. The Firefox Developer Edition browser update is Firefox Developer Edition is up to date 152.0b7 (64 bit). The following extensions are installed AdBlocker Ultimate, FoxyProxy Basic, Ghostery AdBlocker For Privacy, Malwarebytes Browser Guard, Privacy Badger, and UBlock Origin. This behavior got super annoying and I don't know how to fix it. Any help on how to fix this would be appreciated. My operating system is Windows 11.

I had this trouble after Firefox's previous update, where the browser would just close as I was in a tab. It had stopped so I thought the problem was fixed. However, it just updated the browser a few days ago and again I'm having a problem where the browser will just close in the middle of me entering information. It does not have to do with which program I am in as it just seems to happen randomly. It does not save any information I've typed in.
