bold textEVERY TIME I OPEN A NEW WINDOW IT CREATES A NEW TAB. IT CREATES A LIST OF TABS I MUST THEN CLEAR. HOW DO I CHANGE IT TO REPLACLE MY CURRENT WINDOW INSTEAD?

All of my passwords were deleted from Firefox on my MacBook. I am trying to get everything to sync because the passwords are there on my desktop and they are there on my phone. However when I try to sync from my phone nothing happens. When I try to sync from the macbook it is telling me to go to Firefox on my phone and sign in on my phone. The problem is that I'm already signed in on my phone so it is really difficult to follow the instructions because what it's asking me for I'm not able to do. I'm just trying to figure out how to sync the passwords and get the passwords back in the Firefox on my MacBook.

Up until the last week, on my iMac, if I clicked on the Firefox button on my bottom toolbar, both of my main FF windows (each with multiple tabs and open all the time) would come to the front of the screen.

Now, only one window comes up and I have to specifically select the other window to see it.

Is this a new behaviour or have I inadvertently deactivated whatever it was that let me do as I have always done previously!

I can't find any setting that appears to refer to this condition.

I have two separate Firefox accounts, with separate emails to log in and their own sets of bookmarks, passwords, etc. I want to merge all the data from both of those into a single profile of a single account under just one of the emails.

I'm pretty sure I've done this before, by: 1. Logging into account A and syncing. 2. Logging out of account A without deleting data. 3. Logging into account B and syncing. With the result that account B now contains all its original data plus all the data from account A.

But when I just tried to do this process now, at the point of logging in to account B I got the error "Account limit reached for this profile. This profile was previously synced to a different account. To keep your data organised and secure, each Firefox profile can only be synchronised to one account. To sign in using [account B], create a new profile."

I don't want to have separate profiles with the data from accounts A and B, I want it all merged into the same profile. How can I achieve this?

Hello, I've been getting this press and hold authentication the last several months I press and hold then release when the check mark shows, and it still won't let me into the webpages. Happens sporadically, real estate, walmart, and some others. Attached is a sample.

Can you tell me how I can stop it?

Thanks

Running on a Macbook with Tahoe OS. Certain websites will not display my responses to a checkmark box. Certain websites will not permit changing a checkbox default setting. Specific example: https://cards.barclaycardus.com/ has a checkbox with remember user name defaulted to a check. Attempts to click to remove the check do not work. Also, on certain websites when entering login information that is incorrect, the message indicating to correct the item(s) in red or highlighted does not display the incorrect items in a highlighted condition. In fact at the bottom of this page, the response box labeled Email me when someone answers the thread does not display a response when I click on it, even though the "response" is accepted.

My System Administrator upgraded my Macbook Pro laptop after upgrading from Sequoia to to Tahoe version 26.4. This was a JAMF migration. The reinstalled Firefox does not show my bookmarks, after logging in to Firefox with my username and password. I tried to restore bookmarks but it loaded only a few, from more than a decade ago.

We had a power outage in our area. Afterwards when the power was back on I could no longer get CNBC.com to work properly. It kinda opens but nothing goes live nor do the videos play. If I switch to Chrome everything works, but I like Firefox! Lynn Nichols

I am using Firefox 148.0 and Mac Tahoe 26.3.1.

When I click on a link in an email, two Firefox windows open. The window to the link opens, along with my homepage window, so two windows are opening in Firefox instead of just the one containing the link address. This is happening when using Thunderbird. However, I have tested this using Apple Mail and Outlook, and the same problem occurs. This problem happens whether I have Firefox already open or not. I have opened the email links with Firefox running in Troubleshoot / Safe mode and the problem persists. I have also cleared Firefox cache / site data / history and the problem concerning email links is still there. This problem arose after installing Firefox 148.0.

Anyone able to help solve this problem? Thank you for taking the time to read this report.

Can you help providing a sync from the last 30days. Using a backup computer as my current computer is being repaired and bookmarks/passwords will no sync on this machine

I have a local Rocky Linux server running a nginx web server. I am using a Macos laptop. I am trying to install a self signed ssl certificate using openssl on my web server.. The certificate I generated works with Safari but not with Firefox. I have copied the certificate to both Safari and Firefox for local use. Privacy and Security, Manage Certificates, Your Certificates. Firefox complains that that my TLS is tls 1.1, when I am using tls 1.3:

An error occured during connection to tls-v1-1.badssl.com:1011. Peer using unsupported version of security protocol.

My test on my server shows:

sudo curl -v https://caprock.home

Furthermore I can't seem to delete the certificate from Firefox and re add it?

Hi there.

Since quite a while Firefox is trying to enhance our browsing security by "upgrading" connections from "http" to "https." This may generally be a good idea, but it is literally driving me crazy at the moment because it also does so for "internal" sites I host within my LAN (such as my "Home Assistant" instance or a Zigbee coordinator, accessible via its own hostname and web UI). However, these connections will fail, because I don't have certificates for my internal hosts, and thus there is no "https" listener. :-(

(I use my own subdomain "<host>.city.internal.example.org" internally, so Firefox may be confused?)

I feel this behavior has become "more aggressive" within the last few days, so maybe it is due to a Firefox update?

Is there a bullet-proof way to prevent Firefox from doing so?

I've already set the below options to false: - dom.security.https_first - dom.security.https_first_for_custom_ports - dom.security.https_first_for_local_addresses - dom.security.https_first_for_unknown_suffixes - dom.security.https_first_pbm - dom.security.https_first_schemeless - dom.security.https_only_mode - dom.security.https_only_mode.upgrade_local - dom.security.https_only_mode_pbm

Help, please!

I'm close to abandoning Firefox in favor of a different browser, because at the moment it's close to being unusable for me anymore... :-(

Kind regards,

Ralf
