Firefox Support Forum

Hi I'm having problems sending emails, with a constant message, as per the example posted here: SMTP error from remote server for RCPT TO command, host: devon-gov-uk.mail.protection.outlook.com (104.47.11.74) reason: 550 5.4.1 Recipient address rejected: Access denied. AS(201806281) [DB5EUR

I have been with FF for years now but I started to notice a few months back that sometimes a web site I want to go to would not load with FF - a blank page would come up. Also, that some sites were very slow to load. I would go to EDGE and the sites pop right up with no problems.

Some examples - StartLogic, VERY slow to load on FF. United Health Care - I bring up the site, put my login info in and it brings up a blank page. I go to EDGE with both of these programs and no problems. There are other sites that I have the same problem with.

What's going on with FF? I would like to keep using it but I am finding more and more sites that act like this.

Tks - jb

So a few months ago I was having issues with Firefox so I deleted it. But today I redownloaded it, and it was working fine, but all of my data is gone my passwords bookmarks my history is there anyway to get this back.

I just installed Firefox 2 days ago on a new computer and have no problems till today. I was watching a movie when suddenly all tabs crashed. I have tried uninstalling and reinstalling, checking for malware, making sure firefox was up to date, clearing cache data and history, disabling plugins running troubleshooting mode and restarting my PC. Please help I cannot use Firefox at all.

Hi there I love FireFox, after years of others recommending, I finally switched and really appreciate so many great features (automatic downloads not at all though). Anyways, I have a Tivo with in house and out of house streaming to Watch Tivo web app and Tivo android app. Until recently, was able to stream anything from Tivo Box throughout house. Android app works awesome, but no longer working on FireFox (or Edge & Chrome) Research shows this is due to a change in website security which is maybe similar to FF issue?

Chrome offered advance warning/remedy..as detailed below....

I am hoping FF team can rise to the challenge and get tivo online working again for the millions of us who still use and love our Tivos.  Or maybe another Tivo fan has a workaround they can share? I sure hope so, I have wasted hours already troubleshooting and hair pulling :(     Any and all assistance appreciated

Access to XMLHttpRequest at 'http://(MYIP):49152/sysinfo/json/svcinfo' from origin 'http://online.tivo.com' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `private`.

After researching that i found this link Chrome CORS error on request to localhost dev server from remote site

it went into a bit about how "Chrome has implemented CORS-RFC1918, which prevents public network resources from requesting private-network resources - unless the public-network resource is secure (HTTPS) and the private-network resource provides appropriate (yet-undefined) CORS headers."

So basically a public network "online.tivo.com" cannot access my local network (where my tivo is) due to this new CORS-RFC1918 standard.

The is a fix to disable this behavior for now chrome://flags/#block-insecure-private-network-requests

From the last week Firefox started to give me the error "Secure Connection Failed" / SEC_ERROR_INADEQUATE_KEY_USAGE, preventing me to access some intranet sites. The first time I tried the "Refresh Firefox" procedure found at the beginning of the dis-installation function (started through the standard "Add or remove programs" Windows 11 interface). Now this error re-appears only for one of the internal sites from time to time. If I close all the browser windows and re-open Firefox, the error changes to "Warning: Potential Security Risk Ahead" / MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT (which is an error I'm expecting since the intranet site is using an intenal Certification Authority that I've not yet put among the trusted ones) and with this message I can now proceed to the site by selecting "Advanced..." and "Accept the Risk and Continue".

Which is the reason for SEC_ERROR_INADEQUATE_KEY_USAGE error? I cannot find a mention for it inside https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean ... Is there a way to debug it? Or to avoid re-occurring and the need to restart Firefox?

Firefox version is "113.0.2 (64-bit)" on Windows 11 (10.0.22621.1702).

Hello,

I use Firefox at work and at home on the family computer. To have the possibility to access business data at home, I created a login for my business browser settings. If I micc now from home with my Firfox business account log in and log out again opens the next time Firefox from home automatically the browser with the start tabs of the business. This also after restarting the PC. I want to avoid this at all costs. How can I make the browser accessible to my family again, so that the usual tabs are displayed at startup and we do not need an extra password for the family browser?

Kind Regards

Frank

My issue is a bit difficult to explain. When I downloaded Firefox on a new computer, I signed in using my gmail account email and password. I created many passwords and bookmarks. I wanted to sync my phone and laptop to this account but I already had an account on my laptop. My new computer all of a sudden notified my that my log in was disconnected. I signed back in to my account and now it is only showing my bookmarks and passwords that were on my laptop and not my new computer. I only want the things I have added to my new computer and not what was on the laptop. How to I retrieve the bookmarks and passwords that I had set up prior to Firefox disconnecting me?

I installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome. t

Hi, I experience consistent tab crashes in my Firefox app on the computer since yesterday. It works only in troubleshoot mode and not in normal. I tried refreshing and reinstalling the app, installing Firefox for Web and nothing worked. Cleaning data and turning "false" preference media.wmf.vp9.enabled didn't work either. I also tried deleting all extensions, turning off recommended performance mode (using hardware) and enabling default theme. I haven't installed anything recently. Last Windows quality update 24.05.2023, last feature update 08.03.2023. Firefox app still works perfectly on my phone, so it's probably something with the computer. What can be the cause and what can I do to fix it? Added info about crashes below

Thanks

In my MS Windows 11 system in control panel, Apps > Default apps. Firefox is listed twice. In both of these there are these two separate listings: ".htm" and ".html". Below both these listing it says: "Firefox" "Firefox HTML Document"

Question: Can I remove/delete/uninstall one of these Firefox's? Question: Should I remove/delete the ".htm" and just leave the ".html"?

Hope this makes sense. Thank you for your help.

When I open a pdf and close it to a certain page, after reopening, firefox brings me back to page 1 and not to the last page I read. To make it a perfect pdf reader, it would be great to implement the memory of the page in use.

os = ubuntu 22.04 - 5.19.0-42-generic Mozilla Firefox 103.0.1 I am attempting to connect to a proxy that does not require a username and password, yet moz-proxy is continually asking for one. If I put any input in the prompts, it goes away, but if the machine is rebooted, the prompts begin again. How do I permanently stop firefox from asking for the username and password?

When I try scrolling down on this website it automatically takes me to the top of the webpage like a reset. The hardware is fine because it is happening with touch pad and external mouse both. Even though it is happening only on 1-2 website, I am not sure whether it is my browser's issue or the website itself is faulty. Also, specific part of the URL keeps on refreshing nonstop : ?ref=n2dXHxxxxxxxxxxxxx

Hello, I have somehow replaced by bookmarks with empty bookmarks, and I don't have the previous version in backups on my local machine.

Could you help me?

Video download helper is installed but icon is missing from toolbar and cannot be found where I'm told to look when I google the problem (i.e., view/toolbars/customize). Nor can I drag it to the toolbar from where I find it when I look under triple bar/addons and themes in the upper right corner of the toolbar. Where else should I look to find it?
