I am currently using Firefox v. 100.0 (64-bit) on Windows 10 Home v. 21H2. Recently, I have been unable to get package tracking information from the website fedex.com, nor can I log into my FedEx account. When trying to track a package, the FedEx site displays the following message: "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later." Likewise, when trying to log in, the site shows this message: "We are having trouble establishing a connection. Please refresh the page." Repeated attempts in both cases have failed. In the past, the fedex.com site has functioned flawlessly with Firefox. Moreover, I do not experience either of these problems with Google Chrome.

Please advise.

I'd like to permanently delete an account that was set up on a former employers email address (email which I can no longer access). Unfortunately I have no secondary email address recorded in the account and all the options on my account page require that I authorise any changes from the email account which I can no longer access.

Is it possible to delete the account?

After recent latest update 99.0.1 Mozilla is slow to start. It seems to hang. I use Google as my homepage. Am Windows 7, 64 bit. I tried refresh and made Mozilla my home page. No difference. Chrome opens fine. Was really disappointed with refresh. It dropped a number of icons for shortcuts on my desktop - ????? which were a real pain to replace because making shortcuts with Mozilla is not possible without changing the User Account Control setting in Control Panel which I was unaware of but found after searching for 1/2 hour. I have no idea when this changed nor why it did on the Mozilla side because I have been using Windows 7 for 12 years. I am sending this using Chrome as my browser.

I have had it with Firefox playing cop. I really have. I have a site that I visit frequently but these past two updates have now broken my ability to sign into the site at all, even in private mode. All I get is the shield and human icons with the strike-through and the error message on the user name/password field that says: This Connection Is Not Secure. Logins Entered Here Could Be Compromised. Learn More.

I've hit the escape button, tried private windows, done everything I can including resetting which was my last resort and which I hate doing, there's no more whitelist, no way to bypass anything, this is totally unacceptable that I cannot get past this. Firefox is becoming more useless to me as they try to become more and more in control of what I can and cannot do. If there is no override to this, then I have to find a different browser because it's pretty useless to use one browser for some sites and another for other sites, don't you think? So if someone has a workaround for this problem, can you please tell me what it is?

I need a FireFox feature that allows me to access the typical Cable Modem Gateway Web Manager addresses (192.168.0.1, 192.168.100.1, etc.) even when they have no security certificate.

I have been using a Arris SURFboard SBG6782-AC Wireless Cable Modem Gateway (purchased at TARGET) for over five years without significant issues. About three weeks ago my MoCA network began having issues. I tried to login to the WEB Manager of the Gateway at (192.168.0.1) using FireFox. I got the following FireFox Msg:

Secure Connection Failed

An error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I finally used an old version of "Internet Explorer" which allowed me to bypass the security warning and connect via a direct ethernet port of the gateway. Evidently someone (Spectrum claims they didn't) downloaded a different firmware version into my Gateway. (D30GW-EAGLE-1.5.4.0-GA-10-NOSH) i.e. not the factory original version. The WEB Manager interface is different, password requirements are enhanced, the MoCA feature can't be enabled, and it seems Arris no longer provides a security certificate for the 192.168.0.1 Gateway address.

Considering the complete lack of cooperation of Spectrum and Arris, I think it is unlikely that I will ever be able to recover the factory original firmware; So... How about adding an "exception" feature to FireFox settings to allow me to at least access my "unsecure" Gateway. I really don't want to go back to using IE. By the way, I wrote this on a WIN 8.1 HP laptop. My main machine is a Dell XPS8300 running WIN 10.

Thanks, Robert R. Hurley

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

I am on Linux Mint, Firefox 100.0 and I am trying to access a website, https://www.citapreviadnie.es:38188 (requires personal DNIe certificate). However, I keep getting SSL_ERROR_UNKNOWN_CA_ALERT. If I view the certificate of the website,

1. Firefox doesn't tell me which part of the chain is invalid or not trusted (or I don't see it) 2. When I try to download and import each of the CA certificates, I get an alert saying "This certificate is already installed as a certificate authority." 3. If I try to import the whole chain, I get another alert telling me "This is not a certificate authority certificate, so it can’t be imported into the certificate authority list." 4. If I try to add a permanent exception to the site, I see "This site attempts to identify itself with invalid information", but if I click "view certificate" I'm back to step 1, and adding the exception does not have any effect.

What am I supposed to do now?

Instructions on changing primary email address not helpful-prompted to access Accounts but profile displayed would not let me edit my primary email address. When attempted to add secondary address was notified that code was sent to my old email address was was compromised & deleted by security of my carrier Want to add new email address & add secondary email account. Assistance greatly appreciated

Couple days ago Yahoo Mail stopped downloading attachments of any type. Only happens when using Mozilla. Yahoo mail works fine with edge and android. The following had no affect: (1) signing out and in to yahoo mail. (2) Clearing cache etc in Mozilla (3) rolling back recent windows updates. Occurs with all types of attachments, so not an app issue. Appreciate your help, please include only those suggestions which consider the "suddenly" part...

I am running Firefox 99.0.1. Lately (probably since the last update) when browsing the web, Firefox will lockup and not be responsive to clicks on hyper links. The issue goes away when I close Firefox and re-open, but after clicking on 3 or four links, it locks up again. MS Edge does not have this problem with the same websites. I did notice in Task Manager that Firefox is opening up 10 processes. Can anyone give some suggestions?

I just updated to FF 111.0. After restarting FF comes up but then nothing. After a bit of I got the option to force close it. I tried opening a Private Browser and that worked fine so I figured it was one of my add-ons. However after closing the Private Browser and trying opening normally again it worked just fine. Disable all of my add-ons and for the same issue.

Renamed my AppData/Roaming/Mozilla folder and starting as normal worked fine. What a giant pain in the <bleep> trying to set everything back up.

Performed some more science and noticed this. After setting my Mozilla folder back, starting FF, and looking at the TaskManager, There would be 3 processes, one of those after a bit of time would show in red as Not Responding (or words to that effect). Clicking the window a few times to get the force close dialog again. Trying to open FF again, it opened just fine.

So I'm tempted to blame something in the update that is causing this. Yes, I could just start with a fresh Mozilla folder and reinstall all of my add-ons and blah blah blah, but whose to say that after setting everything back up the way I had it the problem won't come back.

I have thought about rolling back to FF 110.0.1, and suppressing the update check.

I used Samsung smart switch to transfer data to new phone. When I tried to sync Firefox on new phone with my PC, old phone and tablet I was asked to type in the authorisation code. No matter how I have set my e-mail accounts no e-mail is received in my spam folder or in-box. There is no way to contact Mozilla to resolve this. I have not received any e-mail to state that my sign in was blocked for security reasons nor have I received an error code. I setup a bugzilla account and tried to request that my account be unlocked but there was no way to do this. All it has done is to create an entry that I reported "Zarro Boogs found". How do I get my account unblocked as the advice on the help pages is no advice.

My email changed from a .com to a .org and I was forced to reinstall windows before I could change it so I can't recover my account, which has passwords I need attached to it.

I have been successfully using FireFox for many years, recently we downsized into a Condo,now 81 years young. I have FireFox as my default browser choice, but it only lists Google on the search bar, when I type in my search in the box under the Firefox name it immediately jumps up to the top of the page Google browser.

How do I get back my screen to use FireFox as my search engine ?? I have tried to change it but will only give me two options Google or Google ?? Is it possible to go back to the screen and try and start again??

Many thanks to anyone who will give me info as to how to rectify my problem, be gentle with me as I am efficient in using the computer but less so trying to solve my problems. Robin

I'm uploading changed webpages to the internet on a daily basis, using Firefox. I'm Using Firefox version 100.0 now and I have discoverd a problem with version 100.0 . From Firefox version 99.01 and downwards, this problem never existed before. The refresh button in Firefox 100.0 ( Ctrl+R ) no longer works good anymore! Sometimes it works good, the other time it's not working correct anymore, you will not see the latest uploaded webpage on the internet. The only solution to this problem is bij closing Firefox and restarting it. Only then you will see the latest uploaded webpage on the internet. Please have a serious look at this annoying problem in version 100.0. This problem can only be discoverd by people who are uploading new webpages to the internet, not bij the regular internet-users/visitors.

Since upgrading to Firefox 99.0.1 when I bookmark a web page into a specific folder, the URL does not appear when I open that folder. A restart of Firefox does not fix the issue.

But if I try to Bookmark the same page again, I am asked to edit it. So it must be in the folder but it is not visible! Help!

Ever since Firefox updated to the new version I've been having constant crashes. I've tried restarting in Safe Mood which doesn't help. Pretty much Firefox will open, say it's not responding, and then by the time it looks like it's about to restore my tabs it crashes. I had to do a refresh and transferred the backup files from an older session which worked, but then it eventually crashed again. I uninstalled and reinstalled Firefox and tried opening my older profile but it keeps happening. I really need to restore my previous session. There's nothing with my computer that seems to be causing it. I did have 2 windows open with about 8,000 tabs total which I'm sure could be part of the reason, but it never really had trouble before and only just started crashing since the update. Is there any way to fix this without starting over? I read that this is a bug that others have dealt with previously.

Some additional information. I'm on a 64-bit Windows 10 PC.
