I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

Installing root CA certificates

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

  1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

So, my browser is disabled. I can open it, but if I type anything in the adress bar (the home menu with recomendations and the search tab doesn't pop up) it will process the information, but then stop and gives me a blank screen. I send an image of it. For example if I type https://www.google.com the tab will go white and I can't do anything about it. In the apliccation menu, the only thing I can do is to go into troobleshooting mode by clicking the Help tab. Everything else (except for the new tab or window tool) is disabled. I beleive it is coused by the fact I can't open any website and those tabs are links. Please write back.

Am I understanding this correctly?

HTML backup (bookmarks) doesn't support tags and annotations, but JSON backup does, and JSON backup doesn't preserve the website favicons, but HTML backup does?  

So, what I can do, is restore my (saved) bookmarks using JSON backup, then restore the HTML backup, this would get my tags and annotations, and the website favicons back? But the downside, I will need to remove duplicates?

I don't think "Tabs" is the right topic, but maybe it's the best of the choices since "Other" isn't an option.

I have an email with a link to a monthly newsletter, which should take me to February's issue. When I click on, or copy/paste, the link, I end up with the January issue. When I copy/paste in Chrome and Safari, I get the February issue. The newsletter people suggested clearing my cache/cookies in Firefox, but that didn't help. No matter how I try to navigate to the newsletter in Firefox, I get to January. I have tried everything I can think of, and still get the January issue in Firefox, while that same link gets me the February issue in Safari and Chrome.

I'm using Firefox 122.0.1, on a MacBook Pro (Sonoma 14.2.1).

I'd appreciate any ideas you might have!


/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.
