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)

I'm using Floorp and its working perfectly aside from this one or two pixel thick line of white that completely borders the left side of my screen every time I open the Browser. Is there any way I can fix this?s

When I want to send a message (Thunderbird)I receive this message since 10 days (about..): "Clienthost rejected by spamhaus for spamming issues". see htps://check.spamhaus.org/query/ip/37.66.26.22 for further information I can use successfully WEBMAIL Can you explain me what is it? Thank you

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.

How do I turn off the caption box. I can't find it anywhere in my controls. Also scrolling has been affected and works poorly. Is this a virus? I never changed any settings to enable this intrusion.

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.

Firefox history contains youtube videos I didn't watch (and that aren't in my google youtube history). I've realised they go back May, roughly when I got my new linux machine and installed Firefox. However, they also seem to have been watched outside the time any of my devices apart from my phone are on. They're mostly just junk videos about minecraft etc.

See attached pic - the ones this morning between 5.48 and 7am I didn't have the laptop turned on. My phone was on though, but by the bed.

How has this happened and how can I track down how to stop it?

I'm writing this on my Windows desktop, can send details of other devices if useful.

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

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!

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.

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 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

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.
