Since updating Firefox to 140.0 (I am currently on 140.0.2 on macOS Sequoia 15.5), when I launch a Firefox window using the non-default profile, that window is not able to load any pages. When I try to close that window, it either requires me to "force quit" it, or if I wait long enough, the Firefox crash reporter appears.

When I first create a new profile, it works. However, after closing that window, or restarting Firefox, the non-default profile can't load pages and eventually crashes.

Things I have tried:

• Deleting all profiles and re-creating them.
• Using new-style profiles instead of the ones managed by `about:profiles`.
• Visiting a local address using an IP address to rule out DNS issues.
• Starting with the non-default profile (using the new-style profile switcher)
• Starting the non-default profile in troubleshooting mode (the browser crashes when trying to restart)
• Clearing the startup cache in the non-default profile (the browser crashes when trying to restart)

I need to know where to go on Firefox to clear my cookies. I'm having trouble completing purchases using PayPal. When I go from PayPal back to the shop to complete the purchase, it will not pay to complete. PayPal says all is okay on their end. One person suggested clearing my cookies, but I don't know how to do that. Please help if possible. Thank you!

Had a 'Onetel' e-mail address for years and have had the same issues with it a few times where as it just 'drops out.

Have been on here before and received good advice. Last time it dropped out apparently because it didn't know the servers name and that was it it didn't want to play any more. I am determind to get this working again so that I can send from One Tel. It has a Forwarder to another account so I still get the messages. Also have gone in via TalkTalk (who apparently now own Onetel and can receive the messages on my phone (iPhone13) but very hard to reply from it. Any help to get this account up and running from my Desktop gratefully recieved.

Thanks, Dick.

Whitelisting WebSites When I asked this, a Mozilla page popped up entitled Firefox Focus ... described whitelisting but am not sure if this is integral or Firefox Focus is an extension ?

I usually use Nightly as my default browser in a Windows 11 system. Recently I started to get a new error message showing up when I try to select multiple messages in Yahoo e-mail. I select them by clicking on the first message, then holding down Shift and clicking on the last message in the range. That should turn on the selection boxes for all the messages between the two.

Now, when I press the Shift key, I get an error box right on top of where my mouse cursor is, so it interferes with me. The top of the box says "mail.yahoo.com", which is the web-site I'm signed in on. Then it has a link with the text "Login - Sign in to Yahoo". Below that is an ad for all the wonderful things I can get by signing in to Yahoo. At the bottom is an error message, "We can't generate key points for this webpage."

I tried the same action in the current General Release of Firefox, v140, and this does not happen. I suspect that this is an intrusion by some sort of AI software, but I don't know what setting might have been activated to turn this on. Does anyone have any idea how to turn it off?

In FF, in the password utility, the entries are sorted by domain. That establishes that a domain sort is possible.

However, every export utility I have encountered, if it sorts at all, sorts by line.

One use I make of a printed copy is as a maintenance markup document. Some of my accounts - eg mozilla.org - have multiple access addresses in the same domain. A line sort scatters them, and I need to somehow collect them.

Would it be a big effort to output sorted by domain?

Recently I had to rebuild my PC Windows 10 .

However Download speeds in FIREFOX are very slow, 10Mbs BUT Microsoft EDGE browser runs at 50Mbs. What is going on? I have Relinstalled Mozilla several times but no luck THUNDERBIRD works - but I have no way of measuring its speed.

I have followed all the suggestions from COPILOT with no success

Any suggestions would be helpful

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

Greetings!

So every time Firefox has an update for my tablet (Samsung Galaxy Tab A8, 64GB SM-X200, Android 14, One UI 6.1) the settings always, ALWAYS reset. I have to go back in and change everything back to my preferences. I've cleared cache, restarted who knows how many times and it still happens.

I have Firefox on other devices, both Samsung and otherwise, and it doesn't happen anywhere but my tablet.

Ideas? Suggestions?

Recently the options to customize what I'm seeing on my Firefox Home page are gone, but only on one PC (running Windows 10 pro). On my laptop (Windows 11 home), I can see my settings just fine. I tried resetting, then uninstalling and reinstalling Firefox but that didn't solve the issue. I've also disabled extensions.

Hello, I usually redirect incoming email automatically to custom local subfolders (POP account).

Today I noticed that, since october 2024, my Message Filters started copying emails, instead of moving them, despite the still-correct instruction. So I'm left with a bunch of duplicates.

Does anyone know how to fix this bug?

I had to get a new laptop for widows 11 as my old one could not upgrade from windows 10. I trasferred my old laptop to new, but when I downloaded new Thunderbird, my address books did not come over. Where are they and how can I import them to my new laptop? I do not know what version Mozilla Tb that i was using. Please help

After update to 140.0.2, clicking on Firefox icon in the dock does nothing. The title bar says Firefox is active, but nothing shows on my screen. What changed? Did you reset something in my preferences?
