I've been using Firefox on device A computer in the evening, and the next day, after opening device B computer from sleep, a tab was open from the device A session (along with some older tabs I kept open, it was placed at the most right location). I am 100% certain I did not have that tab open from previous session on B.

The only way this tab would be able to appear on device B is if I somehow triggered a "send tab to device" functionality when working on device A, however, I am 100% sure I did not. Seeing how I would have to right click the tab and select a submenu to trigger that, it seems essentially impossible that I did that by accident.

Q: 1. Is there a keyboard combo that could be accidentally hit that would trigger Send tab to device? As far as I could research, there is no such shortcut. 2. Can a website trigger this API and perhaps I approved it by accident? I would definitely also notice this. 3. Is there a sync audit log I could check on either device to see if a tab was synced? I found about:sync-log but nothing really useful in there.

This event is so weird that I am considering secirty aspects or a potential exploit vector..

As a resent change Firefox closes all my open tabs when I exit. That is not what I want. Not sure if it's an update to version 128.13.0esr(64-bit) that is the reason for this issue.

I History I have the settings: - Remember browsing and download history (activated) - Remember search and form history (activated) - Clear history when Firefox closes (deactivated)

I have activated "Confirm before closing multiple tabs" and when I exit I get a notification that Firefox will close all tabs.

Is this a bug or do I need to change a setting somewhere ?

Hello, I freshly installed my new computer and so my thunderbird version is now newer than before. I use Debian 12 with Thunderbird and Firefox 128.13.0esr now. I do unfortunately not know which version I had before, but I think my problems come from Thunderbird version, not from Debian.

I have 2 problems with the new dialog windows of Print, Save as, Open etc.

1. e.g. when I click on "Print", the dialog window opens and my problem is the position of the Button "Print". Now it is in the upper right corner and always before it was in the lower right corner. Can I change this position of the buttons?

2. e.g. when I click on "Save as", the dialog window opens and my problem is that the field of the filename in the upper middle is much too small in width. Before when this field was at the lower middle to right, there was much more width for the filename. Can I change the width of this field?

All in all my both problems are with dialog windows, which I think are Mozilla / Thunderbird / Firefox exclusive, because in other apps there are dialog windows which look completely different. Is there a way to change the entire "optic" of the dialog windows or maybe I can prevent Mozilla apps from using their own dialogs and use my system standard dialogs?

Best regards

Hello Forum,

I am unable to see the microphone/record audio button in Google chat in Firefox. This problem is NOT existing in Chrome/Edge/Safari.

Firefox version: 128.13.0esr (64-bit) OS: MacOS Tahoe 26 Beta 7

Please see the screenshot

Hello: I am trying my hardest to figure out how to move my existing Firefox profile folder (with bookmarks, passwords, etc.) to a new system. I have tried repeatedly to take the contents of the existing profile, and past them into the default profile on the new system. None of the information shows up.

The existing profile is version 115.25.0, running on a Windows 7 Pro platform.

The system I'm trying to move the profile to is a Windows 10 Pro 64 bit system. I installed the same version of Firefox on the target system.

All the files from the existing system seem to copy over to the new default profile folder fine, but no luck when Firefox is opened.

I also tried copying the entire profile folder over (leaving the folder name intact), and removing the default profile that was set up by Firefox. When I do that it just gives me a message saying it can't find the profile.

Don't know what else to do here. I have a lot of data in the old profile that I don't want to have to re-create.

-S

I have a firefox account but I'm trying to move my bookmarks from one computer to the next. I created a firefox account but nothing moved. How can I get my bookmarks to another computer?

New installation of Debian 13, Firefox setup with sync on successful. However, I wanted to add hone button and a few other mods to the toolbar but when I started customize the toolbar from menu pic the customization page would not work, it appeared and seemed OK but when I dragged and dropped anything it would not work. I could pickup items but they would not place in toolbar and just snapped back to the pallet. I tried several different ways to enter the customization area but it was always non-functional.

I recently reinstalled Debian 13 on my workstation. This included installing Firefox-esr from the Debian repositories so the version before and after the reinstall is the same. Despite this, Firefox refused to start until I created a new profile - insisting that my profile was from an older version.

To add insult to injury, it offers a method to import data from Chromium (which I use rarely) but not from a previous Firefox profile.

Firefox Sync works so far as it goes, but not everyone wants to use it. Importing from a local profile should be easier to implement than remotely syncing - especially given that Firefox clients may not be the same on different devices.

And, of course, the initial point is that Firefox should accept a user profile when it was created by the same version. After all, when I upgrade Firefox on Debian, I'm not required to create a new profile. Why should I be forced to do it when I reinstall the same version?

128.13.0esr This is probably a huge long shot I know, because every forum etc on the internet has nothing that ever helps with this, but as it only happens in FF I thought it was worth a try.

Yesterday I changed my Privacy settings to 'delete cookies when FF is closed' and added a few exceptions. Then this Google Search reCaptcha thing started. Changed it back to what it was, basically the default setting there, but it was still happening. It only happens in FF [doesn't happen with Edge] and only on one pc, all other pc's and phones in the house are fine [all using the same network, router etc]. So I uninstalled FF altogether, reinstalled it...this thing was still happening regardless of what settings I use re cookies etc. If I actually complete the super annoying reCaptcha it goes away for about 1 or 2 searches, then comes back.

If I'm signed in to a Google account it doesn't happen.

I even did a fresh Windows install [which actually fixed this the other time this was happening about 6 months ago] but that didn't fix it this time. There is no malware, no VPN, no extensions that I haven't been using for years. Nothing that could ever possibly be considered 'bot-like' behaviour.

Thanks
