A recent update (https://windowsreport.com/firefox-fixes-an-8-year-old-windows-bug-that-broke-virtual-desktop-use/) has broken behavior I previously depended on as part of my workflows: If I clicked a link in one desktop, it would open that link in the browser instance on the last desktop I'd used, so I could keep all my browser windows on one virtual desktop full-screened for easy viewing, then slide back to my other workspaces for messaging/writing/etc.

Now, apparently as a bug fix, every time I try to open a link on a desktop, it creates a new Firefox instance in that desktop instead of opening the link in the browser I have open on other workspaces. This has dramatically impacted how I work. How can I restore the previous behavior? It is so disruptive having new windows opening all the time instead of keeping them in my dedicated browser workspace. If there isn't a fix for this, I will need to move to a new browser.

I started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?

I opened FF this afternoon and it op0end like a new first time install- asking about setting up some damn profiles and showing news, AI, weather and crap I do not want or use..

I can not seem to restore it. All bookmarks, PW, menu bars and links are now gone.

For 3 days, I haven't been able to access my GMX email account. It tells me every time "Login to the server imap.gmx.com with username '[edited from public] @gmx.com' failed. I hadn't changed anything beforehand and all the entered data is correct. My other accounts like gmail, yahoo, works just fine. Tried installing older versions and still no success. Outlook app works fine either. I'm pretty sure that GMX mail server made some changes that Thunderbird is missing. Please verify.

Please let me know if Firefox VPN is now made available for installation for Indian subscribers.

I am aware that Firefox may not have a server in India,as per our laws.

            Thanking You,

Here's the thing, Firefox isn't preinstalled on any PC or Mac or iOS or Android. This is a userbase that already went out of our way to pivot from the default ecosystem to come to Firefox.

So if you keep pushing this "AI" on folks, they have already proven their ability and readiness to leave.

I've been with Firefox since the big Quantum refresh. I already know what other browsers I can migrate to. And I'm a hobbyist writer who has been one of the many victims of AI companies scraping my work for their models.

Reverse course on this AI push, or not only will I leave but everyone I chat with, every computer in my department at work, we're all out.

Hi, i copied my Thunderbird (windows 10 Prof)) to a new Notebook (windows 11 Prof) by overrighting the Standard-Profilfolders (in ROAMING and LOCAL) of the new Installation with the Folders of the old Installation (both are Version 146.0.1 but old is 32-Bit and new is 64-Bit) I use more than 2 accounts, and in some accounts, I created subfolders in the 'In' folder to preselect the emails by rules after they arrive Result is: alls Subfolders are missing and some accounts' 'In' Folder are empty. The Account settings seems to be corrct, means i can load new EMails even if the IN-Folder is empty. But i miss the exosting EMails there and the Subfolders content.

I am running Thunderbird 140.6.0esr on a Windows 10 desktop PC. Yesterday I was accessing my inbox and had a problem. I marked a message as Junk in the message bar. My virus software, TotalAV, flashed up a Red message box say HTML issue - Junk. Following that Thunderbird gave a message saying Junk folder full and greyed out the button on the Message bar. Then the Junk folder disappeared from my folder list and now pressing Junk for a message causes no action. Before the Junk folder disappeared it had 2 unread messages.

My Junk settings say "Junk" folder on: my account name.

I do not know how to proceed. Please help.

There was a issue with my computer due to which I had to reset the unit and once the reset was completed I'm unable to recover my data as its asking for 32 account recovery key, I'm unable to find that key anywhere and need help where can i find the key as there are important bookmarks which I need back.

Since Firefox automatically updated (14.0.1) on my MacBook Air (2025 model) several weeks ago, the Bookmarks and History functions haven't worked. Can anyone suggest how I can fix this?

I have been using thunderbird for a few years now on win 10. Just had to buy a new win 11 system and successfully installed it. transferred my emails, folders and contacts and all seemed to work fine. Now I notice that once I leave it for a few mins, it is unresponsive with just a blue circle where the curser should be. I close it and re open and all is fine again for a few mins. I have tried turning off my antivirus software and disconnecting from the internet but still the same fault. Any ideas please?

I see that any emails I sent using my outlook/microsoft account, two copies of that sent emails get generated under 'sent' folder when it should just be one so each time I have manually delete one copy. I have not seen this issue with other providers like Gmail, Yahoo or iCloud (Apple).

The other issue is which I have only started having today is that when I am trying to attach files the dialog box from which I can select the files open briefly for like 2 seconds (with no contents visible) and then disappears.

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.

Hi, I have been using Thunderbird on my Windows PC for many years. I installed Thunderbird on my Android phone recently but it doesn't work, no emails are seen, and it doesn't seem to collect new ones either. What steps do I need to take to fix it? Regards, Paul

Some time ago I found a way to make Thunderbird mark Junk emails as [SPAM] but still to deliver them to my Inbox rather than to the SPAM folder. I need to do this on a new PC, but I can't remember how I did it!
