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!

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?

TY

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

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.

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?

"I just uploaded a new version of my Firefox extension, but it’s not updating for users who already have it installed. Is there something I might be missing? Shouldn't the extension update automatically? How can I ensure that users get the latest version?"

Do Firefox browsers can change app icons? If not I requested to developer to enhance and upgrade the apps across the platforms. Other browsers can make that feature. I hope developer see my question and fix this.

Recently all my 100 plus Bookmarks all went to Grey Globes. Never had this issue in years with Firefox. I am working on Mac OS desktop version Ventura 13.7.5 and Firefox 140.0.4. How do I get all my bookmarks to come back to normal? I tried hard refresh and cleared my cache.

Apparently, there was a Windows Update last night (Windows 10). Bookmarks disappeared on Firefox. Went to Manage Bookmarks tab. Went to Import and Backup. Then Restore. There's a prompt to Choose File, but nothing appears. Also, on the left side of the Library window it is blank. On a support page, it showed some sort of list of bookmarks. Nothing like that when I pull it up.
