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!

First of all, mods, if I chose the wrong category and this had to go in "customize settings and preferences" feel free to move it :)

So, for several reasons I decided to completely disable SSL and the old TLS 1.0 and 1.1. I still didn't decide if TLS 1.2 is still important or it's enough with 1.3 so for now I am leaving them both. I did this system wide, with PowerShell, following the instructions in THIS THIS article.

But then there's Firefox. I don't know if Firefox can establish SSL (or old TLS) connections despite the system "ban". But I came across THIS THIS article about how to enable TLS 1.3 in Firefox and when I went in about:config and I typed "security" I saw that there are a lot of voices with SSL and a lot more about TLS than just the security.tls.version.max mentioned in that article, so I am here to ask you what to do to be 1000% sure that all SSL and older TLS are completely disabled in Firefox, and that only TLS 1.3 is enabled.

If you have reasons to believe that disabling TLS 1.2 is not a good idea, let me know, but in THIS THIS article I've read that 1.3 is much better and it's anyway backwards compatible with 1.2 in case some server only supports 1.2, so I decided to leave only 1.3.

Thanks!

Long ago I developed muscle memory to type in the main part of a website domain and complete it with Ctrl-Enter in the address bar.

That supposedly adds the www. prefix at the beginning and .com at the end.

Works great except that it seems to append "http:// to the beginning. That often results in a warning that I'm trying to go to an insecure domain.

How can I modify this behavior to append "httpS://" to the beginning to avoid all of these warnings?

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

I cant log into x.com. Whether tracking is set to strict or not. I just get the same error. I have tried re-starting my browser and computer. I currently have it set to strict and have it turned off for this site. Why cant I go to this web site?

I have been running into issues if Firefox affecting other programs. One example - closing a game from the big fish game manager. Normal termination of the game hangs up. Closing firefox, usually via the windows task manager, frees up the game manager and the game properly terminates. However, before having task manager close firefox, I see a number anywhere from 6 to 12 or more - firefox(10) for example - trying to re-launch firefox gets an endless round of messages about firefox not responding and a request to close firefox. So far I have only found one effective workaround to this issue. Booting into safe mode and clearing temp and prefetch. This usually holds but I have been seeing this every day for the last 4 days. What is going on and how do I fix it?

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 unable to login to Spectrum.net. I was able to login until a couple of days ago. I can login through Edge but I don't want to use Edge. I contacted Spectrum and since I can log in through edge they say it is a browser problem.

Hi, I try to visit my website ahsapsaksi.com. When I visit on firefox(Desktop and ios). I see the isimtescil template which is the old version of the website. However when I access from another browser like opera I see the updated website(welcome to acme page) only with VPN connection. I tried to delete cookies, visited in private tab etc., however I couldn't manage to see my updated website in firefox(in both desktop and ios).

Can you help me please?

Now a new update. When I visit the website on firefox with VPN connection, I saw the updated version, and from now on I cannot see the website without the VPN at all. I dont understand what is going on. But I tried to clear that cookie many times. Now it looks like the cookie is deleted not by deleting in the settings but using VPN. Now the problem is I cannot visit the website without VPN. Can you explain my experience? why did it happen?

Bonjour, impossible de me connecter au site " caf.fr " message d'erreur : vérifiez que FIREFOX a l'autorisation d'accéder au Web (votre connexion pourrait être effective, mais protégée par un pare-feu) J'ai désinstallé le pare feu d'avast mais le problème demeure. Avec Google, j'ai accès au site. Merci de m'indiquer comment régler ce problème .

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?
