I am unable to send tabs from my desktop devices to Firefox on my Android device.

- All devices are logged into Firefox Sync. - Sending tabs from Android to desktop works fine. - Attempting to send a tab from desktop to Android, nothing happens. Have tried with multiple different tabs from multiple desktop devices, it never makes it to my Android device. - Synced tabs works fine. I can see the open tabs on all my devices from all my other devices, and it stays up to date. - Have tried logging out of sync and logging back in. Didn't fix the issue.

Desktop devices are running Firefox v146.0.1 on Windows Android device is running v146.0.1 on Android 16 (Pixel 8 Pro)

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

After having created a couple of tab groups with some of the numerous tabs that were already open in my browser (Firefox, of course) and then closing and reopening the browser shortly after, no tabs at all reopened even though this is my normal setting for Firefox: open all previous tabs when opening firefox. This setting had always worked before - as it does now with the new tabs. However, all my previous tabs as well as the freshly created groups have vanished. Do you have an explanation and ideally a way of recovering the tabs - or the groups at least? Thank you very much. Kind regards, Kerstin

I have a new Brother printer MFC-L3780CDW. I can print from Foxfire internet, I can print from Microsoft Word. I can go to my Comcast online account and print emails, but I cannot print an email from Thunderbird from my desk top. I right click the email to bring up the menu. I select print and nothing happens. It dont bring up a print preview window to select printer. It does nothing. My old printer was also a Brother MFC, just an older model. everything worked fine. I called brother and they say since everything else prints it must be a problem in the Thunderbird Application

Some months ago I received an email, but the body of the email was a picture (jpg) from my computer. The sender definitely does not have the image. The content from the sender is missing, and my image is in the body of the email and as an attachment.

This has happened a handful of times over the past 6-9 months, with the same image showing up in emails from various unrelated senders.

I just received an email from my partner who sent me an email with a screenshot attached, but instead of receiving what he sent, I've got an email with my image that randomly shows up in my inbox.

A few days ago it happened, but when I restarted my computer, the unwanted image was no longer present, and the actual email content was visible.

Restarting my computer has not resolved this particular instance.

Does anyone know why Thunderbird is in love with this one image of mine and why it keeps showing up in my inbox in emails from other people?

Hi, just tried to access Firefox via an existing PC desktop short cut and it said "The item "firefox.exe that this shortcut refers to has been changed or moved, so this shortcut will no longer work properly. Do you want to delete this shortcut?" Not sure why it's suddenly done this.Should I delete the app via "Add remove" and re-install.

Pls kindly guide me on how to view my emails in the traditional view without "threads" and conversations/emails are shown according to date of receipt instead of "threads" or "grouping of conversations". Many thanks.

I was working with thunderbird today. Was in a specific email folder I had named "reference" that I use to store various emails, probably around 50 emails in there. Suddenly they all deleted from the folder as I was watching the screen. Checked spam/trash folders and nothing. Also logged into my webmail provider and nothing there either. Any idea what could have happened here? They just seem to have literally vanished. Have used Thunderbird a number of years and never experienced anything like this.

We apparently lost power sometime during the night. When I turned on the monitor and opened FF, I got the error message that it had crashed. As my subject line says, I lost all my tabs, the pinned ones (probably about 10) as well as the open ones (probably between 10 and 15). I also lost all my history. I can't use the 'Restore Previous Session' because it doesn't give me that option.

I've restarted Firefox and also rebooted my computer...still nothing happens. It's up to date, version 133.0. But I have no history beyond this morning. Is there any way I can recover those tabs or history?

And in my FF Settings, there's a link at the top that says "Your browser is being managed by your organization". I don't have or belong to an organization. When I click on the link it takes me to another page that says it's "Active" and there's a huge list of "Documentation" that apparently involves a lot of code. Can you please explain what all that means? Thanks so much for any help!

I recently had to have my harddisk replaced as it had become corrupted. The technician did not reload Firefox or Thunderbird. I hope this can be done as a restore so that I find my bookmarked and favourite websites and my e-mails

After updating to v132 I have noticed a significant increase in the load times for some websites that our users connect to. Using v131.0.3 I usually see < 1 second load times for the two websites I am monitoring but after upgrading to v132 it is consistently taking 18-19 seconds for the same page. I have tried uninstalling v132 and reverting to v131 and it immediately goes back to the much faster load times. I have also tried installing various v133 releases and I see the same performance issue as for v132.

The environment I am working in is behind a network firewall with relatively restrictive internet access and I am wondering whether there are sites that Firefox is trying to connect to for the new anti-tracking or suspicious activity features (or anything else) that are being blocked and are therefore causing timeouts and retries that are bumping the total load time up.

Can anyone think of anything else I could check or change?

When browsing a website that uses persistent storage, Firefox pops up a prompt from the URL bar that says "Allow <site> to store data in persistent storage?"

How can I disable the prompt so it never pops up to ask me and automatically blocks everything?

I looked in settings and didn't find anything and didn't see anything in about:config that obviously controls this behaviour either.

I found a screenshot online of the prompt I'm talking about.

Thanks.

Every time I try to sign in into my FF account in the browser it fails to connect to sync.

I get to the sign-in stage, it already knows my email so I'm prompted to put in my password then it sends me an email with code which I put in then I am prompted to put in my 2FA. I get signed in on a separate Mozilla accounts page but when I click on the Account icon in the top right in my browser and sync starts it immediately fails and says "Account Disconnected". I noticed that this started happening after I updated my email/updated Firefox to 131.0 (64-bit) Windows. Not sure if any of it is related.

I have tried various things like:

1. Logging in and out (multiple times) 2. Refreshing Firefox 3. Checking that I am not always using Privacy Mode (I was not) 4. Changing Profiles, changing default profiles 5. Reinstalling Firefox

Nothing solves the problem. I am now unable to see any of my bookmarks or anything from my profile because sync never works. I want to add that this is NOT a problem on Android. The issue happens only on my desktop FF installation.

I can't log in after changing my email password. My email address is [edited]@telia.com. I can log in with my new password using Telia Webmail. I have been in contact with Telia and they refer you. Best regards Anita Bodin

the Thunderbird inbox does not display received emails and does not display new emails.My web host provider,Hostgator, has all the old emails and is receiving new ones. so they are in their files. So the problem is with thunderbird. I have consulted your support and forums, tried troubleshoot mode... When I right-clicked on the input file and clicked on repair the display went blank and the emails vanished....also at midnight

on 1/16/26 I no longer receiving new emails.

your help will be appreciated

Hallo zusammen,

ich kann meinen Firefox nicht mehr aufrufen, weil er wohl nicht kompatibel mit 133 ist. Es wird empfohlen zu deinstallieren und neu zu installieren. Aber dann sind meine Favoriten, Lesezeichen und Passwörter weg. Ich kann sie nicht sichern, weil ich keinen Zugriff auf die alte Version habe. Wie löse ich das Problem?

Viele Grüße Annette

Hello everyone,

I can no longer access my Firefox because it is probably not compatible with 133 (see screenshot). It is recommended to uninstall and reinstall. But then my favorites, bookmarks and passwords are gone. I can't save them because I don't have access to the old version. How do I solve the problem?

Best regards Annette

I just installed Firefox on a new PC build and Twitch will load but just gets a spinning circle instead of playing the stream. The streams play fine on other browsers but i can't figure out why its lagging so bad/not working on Firefox. I did some digging and tried resetting cache and cookies and switched of recommended settings but nothing seems to work.
