Just did a Mozilla update and noticed the Incognito Mode isn't working the same. I can click a link to New Private Window, but it looks exactly the same as a regular window. Incognito Mode was always purple which help me know I was in that mode. Anyone else notice this? Any suggestions? Thank you in advance.

I was trying to reset my password and was having difficulty and finally I was able to change. I also have been trying to delete VPN and have been unable to find how to accomplish it.

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.

When I search for something it shows up in English, but some text under the result is French as shown in the picture. I use latest Firefox with Google search engine, and I have all settings in Google set to English, And same for Firefox settings

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?

Both Mozilla products spontaneusly disappeared from my computer. Firefox requested a reinstall, and all was recovered. Firefox completely disappeared, and I had to restore from backups. I am seriously worried. What is going on?

Greetings. Have Windows 11 Home . I have noticed in the last month that when I click on the star that Firefox is not saving my bookmarks. I have searched online for resolution to this problem to no avail. I am up to date on my version of Firefox . Could someone please provide the steps necessary to get this feature back. I have used Firefox as my primary browser for decades and the bookmark feature has always worked fine . Thank you in advance for your assistance .

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 use a SAAS solution for my small business (FreshBooks) that has not been working well with Firefox as of late. When I reached out to their customer care department they asked me to follow their resolution steps, which included wiping the cache and cookies for all of my Firefox browser. I did so at their request, it did not fix their issue (it appears to be something their developers are working on solving) and subsequently I lost a lot of retained other sites log-in and history. Is there a way to restore the cache cookies that were removed yesterday? Appreciate your help,

Patrick
