Firefox Community Forum

2 DAYS AGO I got an XUL error notice in my UP TO DATE Firefox. Tried turning on or off at times hours apart no use.

Getting by with other browsers in the meantime. But today At about 1:40 PM CDLST 15 August 2024

my computer locked up completely. Several dialog boxes stacked up and mouse and keyboard were ineffective it gave a virus name which I did not write down and a purported Microsoft number to call but I ignored it. Turned off my computer turned on and ran scan with Malwarebytes software NO INDICATION OF INCIDENT

The help page advice for XUL does not have the assurance NOTED AT BOTTOM.

IS THE FOLLOWING TRUE FOR ALL REMEDIES INVOLVING UNINSTALLING AND REINSTALLING FIREFOX? INCLUDING XUL ERRORS?

ASSURANCE The solution is to remove the Firefox program and then reinstall Firefox. (This will not remove your passwords, bookmarks or other user data and settings which are stored in a separate profiles folder.)

Lately I have been having low memory warnings, but still have some things I can dump to make room.

I have bookmarks and saved passwords from an old computer (x86) that I want to import to a new computer (M1).

I have the drive with all my old files on it, and can mount it on my new computer. It is not possible to boot the old computer to export my files. How can I migrate them using purely file operations to the new Firefox?

When trying to load Firefox an error message pops up saying Error: Platform Version "129.0.1" is not compatible with minVersion >= 129.0 maxVersion <= 129.0

HELP

I came here to open a subject that I will address later, but the situation I just encountered here may be related in some way.

I clicked "Ask a Question" here, after which and the page opened to this.

I did not upload the two "uploaded" images you see at the bottom to this thread. They were actually used in my previous post, but immediately upon opening this post, they were already there.

I cleared cache and cookies, relaunched, but they still remain.

BTW. wasn't there a "Preview Post" option here before? Not now, at least for me.

EDIT: Now, after I just posted, the "Preview" button is there. But why, if there is no reply to preview? It's still not here in "edit" mode.

Most tabs that I open now crash. This has been a steadily building problem that now has made the system basically unusable. I did try clearing history, cookies, etc., but that did not help. Even working tabs can crash when I go back to view them. It doesn't matter if it is a saved site, or a brand new one typed in.

Whenever I type youtube.com into the search bar and hit enter, it says it crashed and i can't get in. Here are all my crash id's by the way

I've been using Firefox for years on Windows 10 and earlier, and I just got a new Windows 11 laptop. On the new machine my bookmarks sidebar doesn't persist. I launch Firefox and open it, but when I exit Firefox and launch it again the sidebar is gone. I have to re-open it every time. This is not the behavior I experience on my other machines. Is there a setting in about:config that I need to change?

let's keep it as brief as possible.. i have no idea what the hell the degraders of cloudflare are doing, for the past YEARS all sites that required cloudflare worked just fine, and now i lost access to multiple sites on firefox because of the cursed "are you human: captcha loop" i'm looking for extensions, i'm seeking github codes that i don't even know how to execute. the loop keeps demanding me to change the browser to a chromium.. isn't this supposed to be treated as a targeted cyber crime? from google against mozilla? how do i fix the captcha endless loop?

Hi there,

I'm new here so please bear with me if I've posted in the wrong place or have missed something obvious.

I running Windows 10, fully updated, on a laptop. I have been using Firefox browser now for many years, suits my needs and avoid's using Goolges Chrome. My Firefox was updated a in the last few days and it shows as up to date on Version 129.0.1 64bit.

I noticed late last night that when opening a fresh window and enter a search term in either the address bar or the Google search bar, my usual choice of search engine, I hit return and nothing happens. Any text I've input disappears totally. Not at all sure what's going on but have found that if I open a new private window Firefow will act as I'd expect without any issues.

I have two other browsers on my laptop, Edge and also Avast's own offering which both work as expected when I enter a search term. Have never experienced this before with the exception of years ago when malware protection wasn't great. It almost seems as though something is just stopping Firefox from searching anything I enter. I can use the bookmarks just fine and then everything works as usual.

Yesterday I thought that maybe following the new windows culmulative updates I was offered and apparently installed just fine, that I needed to restart which a tried and I thought it had cured the issue. Seems that it hasn't and still having the same issue.

Any idea's or thought's on what the cause of this is?

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?

First, let me apologize if I picked a poor topic for this.

I log into a very sensitive site almost every day. Long ago I told Firefox NEVER to save the username or password. Long ago as in probably 2009. I let Firefox handle usernames and passwords for most sites, but never this one.

In the last few days, when I open the link to log into that site, there are two changes from what I had for years. One is that there is something in the Username field. It consists of a string of asterisks, then ends with the end of that username. The second change is that they box Remember my username is checked. I always uncheck it when I enter the proper username and password, but next time it starts out the same way.

What do I have to do to stop that site's login page from starting that way?

Thanks!

I can’t seem to update my Firefox acct. I’ve tried updating it several times and I can’t tell if the update happened. When I try to sign into my Chase acct, it keeps telling me that I need to update the version.

Hello!

I have tried every recommendation I have found to stop the very annoying picture in picture feature in YouTube: 1. Unchecking the Enable picture-in-picture video controls option on the Firefox settings 2. Typing about:config in the address bar and press Enter, searching for "media.videocontrols.picture-in-picture.enabled" and setting it to false.

When I am watching a video on a play list and I want to get out of it and I press the back arrow on the browser tab, I get the annoying pop PIP video. Is there a way to totally disable this PIP feature?

Thanks

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

It's hard to describe what I mean without an example. I type "tart" into the search bar, and instead of the recently visited Wikipedia page on tarts, the autofill suggestions are full of pages in my history with "start" or "starter" in the title, or even in the URL but not the title. Is there any way to change it so the suggestions only contain the exact words I've typed?
