Hi, I've noticed an inconsistency when clicking on Web-based protocol handlers in Firefox on Windows. Specifically, when I click on a mailto protocol, such as "mailto:email@example.com," it directly opens my default email application without any confirmation prompt. However, when I click on any other protocol handler, a confirmation pop-up appears, asking me to confirm which application to use. I have attached an example of what I mean.

Is there a way to configure Firefox to always show a confirmation pop-up for all protocol handlers, including mailto links? I prefer to have the option to choose the application each time rather than automatically using the default one.

As of today, DirecTV is no longer supporting Firefox for watching live streaming. They show the attached image. Brave works, too, btw (Chromium-based browser). Do you know why this is happening? Has Mozilla been in talks with DirecTV about this? I use this feature every day.

When you check the image, you can see two "HOME" entries. This is an issue I discovered after uninstalling and reinstalling the Firefox browser and using Sync.

HOME is my PC, and this image was screenshot on my laptop.

Additionally, the Sync for these HOME entries is not functioning properly. I tested this by opening several sites, and while Sync works well from my smartphone to my PC, it doesn't sync properly from my PC to my laptop.

Does anyone know how to solve this problem? I tried rebooting my PC, but it didn't work out.

Hello,

I am hoping that there is a way in which I can organise (permanently, not just the current display) my bookmarks alphabetically though still separated by folders and bookmarks. In case that isn't clear, the order would be:

1. 1 all of the folders grouped together in alphabetical order, then
2. 2 all the bookmarks grouped together in alphabetical order.

Thanks in advance for any assistance you can offer.

I can't connect to Amazon.com. I keep getting the following error message:

Secure Connection Failed

An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I think this is a problem with Firefox. Any suggestions or should I switch to a new web browser?

I appreciate any suggestions.

Hi. i ran into a broken problem. sometimes when i bootup my pc and start the firefox, My windows crashes immediately. what shuld i do and how i can send the firefox log files to mozilla team?

Latest update (127.0.2) erased all my data. Gone are my bookmarks, passwords, sign-in shortcuts, history, etc. and I'm trying not to panic. Most of my passwords are backed up but my bookmarks are gone as is all my sign-in shortcuts, etc.

I always try to keep updated and never have had a problem with anything other than having to relearn a few new things; but this is a first for me.

I transferred by Firefox bookmarks from my old computer to my new Windows 11 computer. I think they transferred fine. But to access them, I have to click on Bookmarks and then go down to Manage bookmarks and click on it. Then I see them on the page that has all the Import and Backup access on it. How do I get them to appear in the side panel as a list like they did on my old computer?

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

OK - I must be missing something. On my previous browser, Opera, if I wanted to see details of my passwords then I needed to put in the computer password, so keeping them quite secure. However, Firefox seems to let anyone using the browser to access the full details of all my passwords, even offering to copy them! This has to be the most insecure approach possible - surely this can't be correct, can it?

Settings > Home > New Windows and Tabs > Homepage and new windows

This setting got reset on me last night. Using 127.0.2.

So, I set it to custom, add in a URL, close the settings, re-open the settings and see it is set.

I close my non-pinned tabs and then close the browser.

Upon opening the browser, I am greeted with an empty tab and the Setting has reverted to "Blank Page".

Or how about the registry? Turn Off Update

Are Firefox extensions sandboxed from the rest of the operating system? Suppose I have installed a malicious extension/add-on on my system. Would it be possible for the extension to access and tamper with my operating system? I do not care if it tampers with the browser tabs or data inside the browser as long as it does not have a way to tamper with my OS. Using MacOS Sonoma

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

Hi, i have formatted my macbook pro, before i have made a back up with timemachine. I'd like to restore my bookmarks but i can't find it on the back up.

I am using Windows 11 and FF 127.02. I have read the lag issue with Youtube was suppose to be corrected with FF 127.02 but it is not. I have been using FF for many years now an love it. It is my understanding that it is the ad blockers causing the slow down. Do you have an estimated date when this will be resolved. I have tried every trick included running it in diagnostic mode or trouble shooting mode. Nothing seems to work. Not even a refresh.

Thanks
