Firefox autofill always fills my phone number as +!(xxx)xxx-xxxx, despite most forms not accepting the country code. I have tried to remove it in the saved autofill address, but it keeps putting it back in. This makes the autofill not work. Why can I not disable this!?!?!?!

All of a sudden, when I hover over a tab, a small window of the web site that tab is in, appears. Never happened before.

I did go into Performance Options - Visual Effects and unchecked "enable peek," but it didn't work.

How do I stop these windows from appearing?

Windows 10.

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

since my last update my aol email has changed. it used to be 4 accounts were displayed and i could select each one now only one is displayed in yellow along with its password displayed in yellow. also i go to copy and paste but it won't paste.jack c [edited]@verizon.net [edited phone# and email from public community support forum]

Firefox (129.0.2) displays "401 - Unauthorized: Access is denied due to invalid credentials" (see attached image)

I have tried various combinations of setting and not setting the following in Firefox:

• network.negotiate-auth.trusted-uris
• network.negotiate-auth.delegation-uris
• network.auth.use-sspi

For the URI settings I have tried both .domainname.domainextension and https://servicename.domainname.domainextension

In Windows 10 Control Panel -> Internet Options, the site is in "Trusted sites" using a domain wildcard, and also "Local intranet" and both "Automatic logon" and "Enable Integrated Windows Authentication" are enabled. I suspect those setting aren't relevant since other browsers are authenticating without error or prompt, but calling this out to show that I've covered that base.

The web service is served by IIS 10.0 on Windows Server 2022 and the authentication provider list only includes Negotiate, but I don't believe this issue has anything to do with IIS or its configuration as, again, other browsers are authenticating without error or prompt.

Anything else to check?

Thank you for any guidance you can offer.

Hi again,

so, in my other question I was reminded about Browserleaks and while I was there testing TLS I also tested Canvas and it said 100% unique which I was surprised because I have the Enhance Protection in FF in "Custom" with both fingerprinting options selected and in "in all windows", plus CanvasBlocker.

100% unique is not good, right? That's what I thought at first. But then I remembered, CanvasBlocker rotates settings all the time, so even if my fingerprint is 100% unique it's also changing all the time which means "they" can't identify me (supposedly). Then I also thought "actually it might be better than not 100% unique because in that case I might have more issues with websites thinking that it's someone else trying to access my account". But then I thought "although if it's 100% unique changing all the time it's also like if it was a different person".

I deactivated CanvasBlocker and tested again and it was also 100% unique. Then I reactivated CanvasBlocker and I deactivated FF's anti-fingerprint. Again 100% unique. In other words, I don't see a way to see what is the difference between using CanvasBlocker on top of the native FF anti-fingerprint. That's where you can help :)

So, questions.

1) can you tell me what exactly does FF block about fingerprinting? And, does it rotate settings like CanvasBlocker so that this "100% unique" is not actually a real issue because it's different every time? Or is it a bad kind of 100% unique in that case?

2) what would create less issues of websites thinking that I am not me? A rotating 100% unique, or a not 100% unique (in which case, how to I achieve that, considering that neither CanvasBlocker nor FF's anti-fingerprint nor both together can do that?).

Would you say that having a VPN with own DNS which block tracking on a domain level, plus AdGuard with all possible filters, plus FF's Enhanced Protection in "Custom" with all at max, plus CanvasBlocker, is a good combo? Or what could I improve to reach a good balance of not being tracked/fingerprinted, not being blocked "because I am not me", reasonably light resources usage, and reasonable browsing speeds?

I used uBlock Origin previously because it's lighter on resources and it triggers my laptop's fans much less than AdGuard but it doesn't block (not even with element picker) some annoying things of websites that I visit often. In case you wanted to recommend that :)

Thanks!

I am writing this in Chrome on my old Win 7 HP laptop. There are no problems there. Microsoft should have just ended with Win 7, their only working OS. This is a big old laptop, heavy with a 17" screen, fragile, nonworking touchpad and with dying battery. For traveling I actually use a newer laptop - Dell XPS 13, light, sturdy, bright screen, long life battery, tiny... That came with Windows 10 initially and upgraded to Windows 11 later. I used Chrome for browsing initially just like on this laptop. At some point (I don't know whether this happened after Win 11 upgrade, I just didn't pay close intention to what Windows are doing behind my back) I just could not log on to Facebook in Chrome on Dell. Nobody is out there to help. Neither at FB, nor at Google, neither at Microsoft. Everything else worked fine. Before my travel to Europe this summer, I uninstalled Chrome and installed Firefox instead on the Dell. I carried over all my Google passwords. And everything worked fine, including Facebook. The trip to Europe went fine. Firefox performed great. Now a week back in the States, suddenly yesterday morning, out of the blue, without me doing anything to cause that (the day before I shut the lid, and everything worked fine), all hell breaks lose: I can't open a single page in Firefox - yet my WiFi connection is fine, and other devices work fine. Firefox opens the home page but nothing else, when I click on troubleshoot, my WiFi connection is suddenly dropped and I have to reconnect. I don't have Chrome on Dell, but I do have Edge, so I checked Edge: Edge opens some pages immediately, some pages only after I ask it repeatedly, all much slower and more laborious then it should be. So, while it did not lose functionality altogether like Firefox, I would say it is also not operating properly. But Skype, email software, printer connection - they work fine. Some satanic force entered the computer overnight and destroyed browser functionality. And I reseted everything and rebooted and restarted and deleted cookies, all the usual crap they tell us to hide what is really going on (some screw up or intentional sabotage in the code). There are no proxies. Firewall on or off does not matter. List of Windows updated shows the last one on 8/14, and for 10 days there was no problems. I fiddled with command prompt: sfc/scannow says everything is ok, malwarebytes say computer is clean, Edge improved after netsh winsock reset, but Firefox did not, I sent a request for tech support to Dell, but this can't be a hardware issue, it is most probably some software security bullshit issue that happened behind my back and that now requires someone with PhD in programming to figure out and solve. I am totally exhausted and very unhappy with the situation.

This message is to inform you that my email is being leaked from my Firefox browser, in hopes that Mozilla will provide a fix ASAP (if it hasn’t already done so in the latest version?). This leak was made known to me after visiting several websites (sites I've visited previously and sites I’ve NEVER visited before!), where I will receive an email very shortly, if not immediately after visiting and closing the browser tab for the website. (These are legitimate sites that are selling a product and, typically, very politely asking if I need more information, etc. ).

After noticing this, I got in the habit of clearing Firefox memory frequently, if not after every site I visit; but especially when my email is required to login. However, today I just notice that my email address is “permanently” located within the Firefox browser; and have to wonder if this could be how websites are getting my email… The email is located in the Firefox addon Video DownloadHelper app. The Companion App within Video DownloadHelper requires a payment, license #, and email to install. And, when looking thru its new menu today, I noticed my email (the same one I get messages from after visiting sites) is right there within the Video DownloadHelper menu (click on VDH icon, click on gear icon, click on More settings…).

So, I don’t know for certain whether my email is being compromised after logging in to a website and not immediately clearing memory after leaving the website OR if the compromise is from the Companion App within the Firefox Video DownloadHelper app, OR possibly both(?). If it is being leaked from Video DownloadHelper, I would greatly appreciate it if Mozilla would implore upon the VDH crew to remove it from the app.

And, if you can, I would greatly appreciate an email letting me know if/when this has been fixed! Thanks! Regards, Dave

I have been having problems logging into Spectrum's website on my computer. I can login to the website using another browser. I have contacted Spectrum, they went over my entire account and stated that everything is working like it should. The person said to contact Firefox and have them check my account for any blocks. I can access any website and login without a problem using Firefox but Spectrum. Can you please help me. I really like Firefox as my browser and don't want to have to switch. Thank you.

The autofill function works great for forms and applications but not so much when I'm entering online contests. When they ask me for my TikTok, Instagram, or Twitter username, it will not autofill those. I always have to do it myself in FireFox. But Microsoft Edge doesn't have that problem. Why doesn't it remember what I type in for those types of entries?

When using the Firefox browser I find that You Tube videos freeze up after a short while, and the whole website becomes unresponsive. I do not have this problem if I use the Chrome browser, so apparently the problem is specific to the Firefox browser.

Since a recent Firefox update it has decided to log me out every single day which is very annoying...I have looked at solutions that only computer guru's would understand and I have no time or desire to trouble shoot this. Therefore, I will be using a different browser until this problem is solved.

Thank you

I refreshed (to 129.0.2)..... and the iCloud became to dead... (unsigned and unable to sign in) I try to retranslate (from Hungarian) the error message: "During the contact to the server, a mistake/problem emerged". Other browser (Safari on the phone) does not face with it..... (It is possible to sign in.) Is it a bug?????? WHAT SHOLD I DO????????? HOW CAN IT BE SOLVED??????
