I am getting the message "updates are disabled by the admin." I am the only one here so I don't know how that happened. I need to install Slack but need to update first. I followed the steps to edit registry but still can't update. Please advise.

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Moderator note: This question has been edited to precise Firefox and OS version, based on the crash reports.

when I try to access any website I get the same error message

Hello,

On the Firefox home page, there are shortcuts. I have pinned some of these shortcuts. When I click on a shortcut, it opens in the current tab. I would like to have the shortcut I click, open in a new tab, without having to Ctrl+click Is this possible?

Amazon Facebook Ebay National Lottery and others just refuse to load.I tried troubleshooting mode,it worked once and now it doesn't.I believe I'm not the only one with this prob. Help? Thanks.

My Firefox 150.0.3 (64-bit) in Windows 11 on a Dell 9310 locks up when the XPS is put sleep and awakened after 5-minutes or so. No recent Extensions or Add-ons have been installed. I have yet to delete and reinstall Firefox, maybe that's the next stop. I just can't find the problem with my limited tools and experience. Thanks, and appreciate the help.

The Roboform extension does not work :-( This has been going on for 2-3 months now.... It keeps telling me the extension is installed (which it is) but not enabled (which it IS) Thank you

Since April 27th have been various situations where this msg occurs: Access Denied You don't have permission to access ht tp :// signin.ebay.com/logout/confirm?" on this server. Reference #18.17fc3117.1778464971.41591197 An error has occurred

Although the letters in the reference can be different.

1. Trying to open E-Bay with an icon presented in Firefox for E-Pay, or searching Google for 'E-Bay Login', in Firefox, Edge, and Chrome this msg occurs. 2. If I can sign on, when opening searchers from a folder the searches:

	A. Some searches have the words, and show items for sale, but the rest have the access denied msg where the search words should appear. 
Will send a pic when can sign on.

2. If E-Bay will open, sometimes all searches will load ALL with the search words visible in all tabs, but when click on a link for an item to sell, the access denied msg occurs. Sometimes a few searches will load with the name of the search in the tab, but other searches will load with the will load with the words access denied, and the mas when clicked. 3. Some website like Arkaim of some such issued this msg: Your IPv4 Address 104.187.9.142 received a bad risk score. 4. Left msg on Firefox about above, no response, left 2 msgs on E-Bay Technical Support, no response, Microsoft no help, Dell no help, AT & T sent new Gateway/Modem.

IP address changed, and IPv4 changed to  IPv6. Same problem.

At & T said the old router was slower than I paid for: Speed Test 210.6, 29.7 New router 475.5, 225.8. Google AI says clear cache: Clear Cache on Desktop (Chrome, Edge, Firefox) [1, 2, 3] 1. Open Menu: Press Ctrl + Shift + Delete (Windows) or Cmd + Shift + Delete (Mac). 2. Time Range: Select "All time" to clear everything. 3. Select Data: Check "Cookies and other site data" and "Cached images and files". 4. Clear: Click "Clear data" or "Clear Now". 5. Restart: Close and reopen the browser. [1, 2, 3, 4, 5] I saved the icon of Network & Internet, Internet Options to delete temporary files, history, cookies, saved passwords, and web info (same Thiong??????) Lastly Google AI recommended editing the DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1). Any danger in doing this?

The full winget command is: ```pwsh winget install --id Mozilla.Firefox.zh-CN -s winget -e -i -l D:/.../Mozilla/Firefox/ ```

The winget log mentioned that winget downloaded https://download-installer.cdn.mozilla.net/pub/firefox/releases/150.0.2/win64/zh-CN/Firefox%20Setup%20150.0.2.exe ```log 2026-05-12 22:19:28.840 [CORE] WinINet downloading from url: https://download-installer.cdn.mozilla.net/pub/firefox/releases/150.0.2/win64/zh-CN/Firefox%20Setup%20150.0.2.exe 2026-05-12 22:37:42.091 [CORE] Download hash: 6c7fb833ebb13637daf750c7a2c611e2b6d8d324dc2463eed40e8478d0c791fc 2026-05-12 22:37:42.091 [CORE] Download completed. 2026-05-12 22:37:42.094 [CLI ] Installer hash verified ```

Then winget shows the installation was successful, but the shortcuts in the Start menu and on the desktop point to a path that doesn't exist. I noticed that this path is the one I passed to winget via the -l parameter, but it is missing the slash (`/`) > D:/a/b/Mozilla/Firefox/ → D:\abMozillaFirefox\ I couldn't find the installed Firefox either in the root directory of drive D or under the originally expected path D:\...\Mozilla\Firefox.

Although I passed the -i parameter (specifying interactive installation) to winget, I didn't see the installer window. In the user registry, the installer also wrote the aforementioned incorrect path, and I cannot uninstall this installation through Windows Settings.

I wrote a script myself to search for folders or files with 'firefox' in the name (case-insensitive) on my system's C and D drives, and I only found this folder that looks related: ```pwsh > ls "C:\Users\...\AppData\Roaming\Mozilla\Firefox"

   Directory: C:\Users\...\AppData\Roaming\Mozilla\Firefox

I want to know what the installer does after running the above installation, and how I can undo these changes to reinstall Firefox?

Hello. I have a problem with firefox lagging on high end pc, these are my specs for context: cpu - ryzen 7 9800x3d gpu - rtx 5070 ram 32 gb ddr5 6000mhz motherboard - msi b850 wifi 6e

i have a folder of bookmarks called "social media". When i want to check every website there (for example: telegram, discord, whatsapp), i start manually opening them up, so i hit the folder, click the needed icon, open new tab, repeat everything. And the moment i turn on 2 tabs like that, everything starts lagging. I don't think that my pc is the problem, because it is not even half a year old + it has good specs. Maybe there is a setting that i accidentally turned off/need to turn on to remove this problem? I love firefox, and i am using it for a while now, but now i am thinking about switching browsers because of this constant lag that happens. With all due respect, Emin.

P.S. i know that you can open all of the bookmarks right clicking the bookmark folder and then pressing "open all bookmarks", but most of the times i don't need to open all of the bookmarks, that's why i open everything as i said earlier.

Hello everyone,

yesterday I got quite a scare. While Firefox was open, a new tab briefly appeared showing the page about:processes, and immediately afterwards the browser closed itself on its own.

At the same time, Chrome was open in the background. When I clicked on Chrome, a prompt appeared asking whether I wanted to allow changes to be made to the system (the typical UAC prompt). However, I’m not entirely sure if this was actually triggered by Chrome or possibly by another application.

I clicked “No” on the UAC prompt and immediately unplugged my keyboard. I recently started using an ASUS ROG Falcata, which is connected via USB.

After that, I ran a virus scan with Windows Defender — it didn’t find anything. I also ran AdwCleaner, which also came up clean.

At first, I suspected the ASUS ROG Falcata (I’ve only been using it for a few days), since it’s almost like a small computer itself and can execute macros, patterns, etc. I was worried about a possible firmware bug or something worse. At the moment, I’m honestly hesitant to plug it back in and am using an old Dell keyboard instead.

Importantly, I wasn’t pressing any keys at the time of the incident.

Now I’m quite unsure what could have caused this.

Is there any way to trace this in Firefox (e.g., via logs)?

And is there any (event) log where I could check what triggered the UAC prompt?

One more thing I noticed: I shut down the PC afterward and turned it back on later that evening. Everything booted normally and is still running fine today. However, Firefox updated itself yesterday from version 148.2 to 149. Maybe that was somehow related (though there’s no indication in the Firefox update history that anything failed or similar).

Ever since the last update of the Firefox program, I am frequently getting the "Server Not Found" message when I click on links online. If I switch browsers, the links work just fine so it is obviously Mozilla's problem and not anything with my "modem or router" as I am told int he "what can you do about it" message on this error. Mozilla needs to look into this problem and update whatever is causing the failure to link message.

I have always used Firefox. Today - some update has erased all my bookmarks. it says import from Edge - but I don't use that. I lost my job last month so all my bookmarks are so very important and now they are all gone. OMG

Please help.

Site is https://www.ziggogo.tv/nl/home which is a Cable Television provider's site.

Is days of Yore, we users were asked to tell if a site did not work with Firefox. Now I had to find this forum :-(

I'd like to understand what makes Firefox incapable of playing the film featuring my father from the sixties, two 2 years before he died. For me it is not a real problem, because Chrome waits always in the background to take over. I'd just prefer to let it wait for eternity.

I'm on Windows 11.

i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

Firefox FREQUENTLY totally removes added applications attached and it totally screw up my ability to access anything when you remove my Bitdefender application from access then I have to again EXPLORE added applicaitons!!
