OS Version: Windows 11 Home, 23H2 Firefox Version: 127.0.2

I have several virtual desktops: Desktop 1, 2, 3 and 4. Case 1: Assume that there is at least one opening Firefox window in any virtual desktop. And, if I try to open a new window in Desktop x (x = 1, ..., 4), it will appears in Desktop x as expected. Case 2: Assume that there are currently no opening Firefox windows in any virtual desktop. And, if I try to open a new window in Desktop 2 or 3 or 4, it will only appears in Desktop 1.

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?

Hello everyone!!

I've been experiencing a rather "unusual" issue: My Firefox up until version 116.0b8 worked perfectly fine; however, after any updates to versions beyond that, it stopped working.

I've tried the final versions and the betas, but nothing works. I attempted reinstallation and everything else, but I couldn't solve the mystery and remain stuck on version 116.0 beta 8.

What's happening? Every time I try to load a page on any version above 116.0, it either doesn't open or keeps loading in a loop. Yet, if I use another browser or revert to version 116, everything works correctly. This issue does not occurs in others machines.

Has anyone experienced something similar?

Thanks in advance for your help.

For several months, Firefox has been unable to play videos from various different websites, including Netflix, Paramount Plus, Youtube, and others. I've turn off VPNS, reset my internet router countless times, cleared cache/cookies, flushed DNS, updated firefox, updated my video drivers, updated windows, disabled extensions (including adblock), opened Firefox in safemode, and reset hardware acceleration. This is not an issue on chrome or edge. Some of the error messages include: Netflix F7351, Paramount Plus 5000, and error code 102630. Youtube mostly doesn't work on livestreams, and says that my browser isn't compatible.

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

I have Windows 11, Firefox yahoo email. I must have clicked somewhere that consolidated all my email to the left in a narrow format. Can't locate where to correct it. Also had no luck attaching a screen shot. Next to the condensed email, is another column that is blank except for the white envelope. Is there a place where I can change the format? Thank you.

Or how about the registry? Turn Off Update

I am running Mac Big Sur, 11.7.10. When I am in Firefox version 127.0.2 and I go into any Google search, the tab crashes. It works in private browsing mode and also in other browsers but not in non-private browsing in Firefox. I have tried disabling extensions, add ons, etc. Nothing seems to help. This started happening a few weeks ago with any YouTube page also. How can I fix this? If I can't I will stop using Firefox as I cannot function like this. Please advise!

I've been using Firefox for about six months. I'm a MacBook user with the most recent version of Sonoma installed. After a month or so of using Firefox it starts crashing and freezing. Sometimes I can't restart it for several minutes. Whenever this happens, I refresh it. I've refreshed it about twice. I've re-installed it twice too, but it keeps happening. Most settings are default, but I wanted to include the settings in case this could be the problem: - I've turned off Firefox home content - I've turned off all passwords and autofill features - Never Remember History - Do Not Track and Tell Websites not to share/sell my data are turned on - I left the standard-level security settings as is

I have one extension installed.

The only other browser I have installed is Safari and I am not having these issues. I should add that I don't receive any error messages when this happens, it just freezes. The most recent issue is that I was clicking on buttons on a website and it wasn't working, but when I started using the Safari browser (which also set to private mode) it worked fine.

When it works I love Firefox and would like to keep using it. I am wondering if there is anything I can do to fix this.

I want to change "browser.sessionstore.resume_session_once" preference to true. So I do it in about:config page and if I reaccess this page in another tab within the session, then my value is being kept.

However, when I restart Firefox (thru "Exit" in "File" menu), all previous pages get restored and that preference is "false" again in the config after a new browser start.

I also made a user.js file with the following content: // user_pref("browser.startup.couldRestoreSession.count", 0); user_pref("browser.sessionstore.resume_session_once",true);

Nothing helps.

Please let me know how I can modify the config file.

Thank you!

I can't stay on this site for very long at all, and do my best to write out what I need as quickly as possible then leave. I would never contribute to answering any questions other then my own because how bright it is will eventually cause me pain.

In my view, it represents an amateurish view on website design and likely has an impact of skewing the regular user base to people that don't mind it.

Sincerely,

A user who only subjects themselves to this painfully, pointlessly white website if they absolutely have to.

Good Day!,

After masking them with my duck duck go service, I can't find the link to verify my emails. Where can I see any return responses using my mask email?

Dear supporter, our firefox is managed by our company, while download file, not sure why some file type could not setup default option, due to no check box "Do this automatically for files like this from now on", could you share how to fix ? Thanks a lot.

best regards/hing

I can edit my short cuts. One I have added the Name, and the URl, I also have the option to add a custom picture to the square icon for the shortcut. It seems obvious to want, as I do, to "drag and drop" a photo of my choice from my personal collection. For example, when there are multiple shortcuts for the email of each person in the family, their individual photo is a great identifier. As things are now it seems I can only add another URL. I tried to add the URL from a family members Facebook page but it would not accept the link. Can some techno whizzz out there not make "drag and drop" an option? It would be REALLY useful for us all to have the photo of our choice, either a family person where appropriate, or a pet or whatever, or a friend. Thanks. Drag and DRop seems such such a common process now I cant think it would be difficult. Well....I wouldn't know where to start of course, but thats why this is a Help forum! I look forward to you coming up with something! Thanks. Have a great day.

How can I resolve issues with video streams from Facebook Workplace?

This issue doesn't happen in Chrome. When I stream video in Facebook Workplace, the video stops frequently and becomes poor quality at times. I have recommended performance settings enabled, using hardware acceleration.

I'm trying to troubleshoot a connection error and cannot find anything about 'SSL_ERROR_INSUFFICIENT_SECURITY_ALERT'? What is this trying to tell me exactly? Is there documentation or a debugging switch to elaborate this error, or is it really necessary to dig into the source code to find out about this? Even mozilla search and google comes up empty.

I'm running 115.12.0esr on Linux. I have another Linux system running 115.7.0esr that has no problem connecting to the same URL.

Thanks!

Hey all, Before I go to far, here... Firefox version 127.0.2 (64-bit) Windows 10 Version 10.0.19045 Build 19045 Extensions - Malwarebytes browser guard.

What I've done: Cleared cache, history, etc. etc. ran multiple system scans restart app restart windows

So how do I keep Firefox from opening pop-up for about:config? That's right, There are pop ups that firefox allow to open new tabs, and its the about:config page.

Also, every time I start typing out google in the address bar auto suggest fills in googleleadservices or something like that. I already went through all the same steps above and more. I originally thought it was just opening one of the last pages I went to, but if I've "cleared" everything as per the way firefox has it set up, why would it have any history of what the last page was?

David, here are two screen shots (ss) to clarify my issue with email and a third regarding another issue (see below).

Number one ss shows what I see when I go to Thunderbird. I am allowed to delete if I wish by first marking the email and then clicking delete. If, however, I wish to view the message, Number two ss appears. I cannot delete the message without going back to Number one ss as that option has now disappeared. This was no problem on my old computer.

The other issue is related to the above. I have over 250 emails without being able to access them (see Number three ss). On the left upper side is the number of emails I have, but only six old emails appear, something that is confirmed in the upper right frame. No matter what I do, I cannot access them.
