I got a new Windows 11 Dell XPS laptop computer and installed the latest Firefox (v133) on it. On my old computer, it was supposedly syncing/saving the bookmarks in the Mozilla cloud or somewhere. However when I try "Import" on the bookmarks panel, it only offers to import Microsoft Edge bookmarks. When I follow the help docs on this forum, it says to use the hamburger menu to go to bookmarks and then to "Manage Bookmarks" which took me a while to find since it's at the very far bottom of the Bookmarks window, not near the three menu items at the top. Anyway, it brings up a window with more bookmark items but they all seem to deal with my current computer and installation of Firefox, which has only a very few default bookmarks. I do not see anything related to bookmarks synced with the cloud. I am logged into Mozilla on the new computer. I do not have an HTML backup file available, since I thought that the bookmarks would be backed up to the cloud and I could always get them there. Two questions:

1. 1: Is it possible to get my old bookmarks from the cloud?

1. 2: Is the bookmarks have not been exported to an HTML file, is it somehow able to get them from someplace on the C drive of my old computer? I think it should be possible since the bookmarks must be saved somewhere otherwise, how would it know what the bookmarks are for someone who never exported them to an HTML file? My old computer won't boot due to a power surge but I am able to connect it's hard drive to my new computer and see files on it.

Thanks, Mark

The past two days Firefox has not been displaying PDFs properly, turning 2 out of 14 pages sideways. I restarted my computer but no change. The PDFs display beautifully in Edge.

So I have been having a problem with firefox where the window turns completely blank randomly. this happens more often when I have a private tab open. It would literally turn blank every few seconds. Usually when I alt tab it goes away, but then it happens again after a few seconds. The weird thing is is that this only happens on Windows. Both 10 and 11. I also have Linux installed on the same PC and there it doesn't happen. I've reinstalled my Windows multiple times yet the problem remains. Firefox forks like Waterfox also have this problem.

After a Windows 11 update, every time I play some video/sound and stop the playback, my whole computer audio doesn't work anymore. When I reset my computer, the audio comes back again. I tried using other browsers (Edge, Chrome, etc.) and other programs/applications, but this only happens in Firefox.

Any ideas on what can I do to solve this issue?

Basic information:

Firefox version: 133.0.3 (64-bits) Operation System: Microsoft Windows 11 Home Single Language OS Version: 10.0.26100 Compilation 26100 Computer Brand: Alienware m16 R2 Sound drivers: Realtek Semiconductor Corp. version 6.0.9738.1

As title. Installed the latest update as soon as i came out. I get the "Welcome to Firefox" tab and the 2nd tab "Firefox Privacy Notice" opened.

The 1st "Welcome" tab, has the box and buttons asking me to import old setting and all that jazz. I have down in quiet a few times and nothing is taken root. I have went through the process of installing all my old addons and extensions, I am not sure how many times, as I use them every time I open my browser to watch Twitch or Youtube, Beyond 20, and what have you. And of course it keeps resetting my toolbar and the bookmarks and settings on my homepage.

I thought at first, it might be buggy and after a day or two it would get fixed an updated. But alas, nothing thus far and this is forcing me to use other craptastic browsers I rather not even have installed on my system.

I have refreshed Firefox a time or two, I uninstalled and reinstalled, but I am afraid to completely wipe it out, as I do not want to lose my bookmarks, passwords, and other saved information, that I probably should not have saved but I do because my memory is "teh suck".

I would appreciate any insight on how tor resolve this issue.

Thanks!

Starting yesterday, whenever I open Firefox, a second page also opens. It is blank and unresponsive to commands. Doesn't do much of anything. The address in the address bar is for a crypto-currency exchange which I've never done business with nor ever visited to my knowledge. No input either on the main screen nor in the address window seems possible. The only thing functional on the page is the red-X in the upper right hand corner. It works fine. But whenever I close Firefox then re-open it, the second crypto-exchange page is there again. It opens concurrently with the regular Firefox browser page. Which functions normally. I don't know what to make of it, and I don't want it. Does anyone have any ideas???

i need to copy and paste text that's also a link, but firefox isn't letting me highlight it, I can do it in chrome, brave, & opera, it's not a mouse problem either, if I just right click on the page and select "highlight all" FF wont highlight it, is there a setting for this or a extension I can download? (in the picture the the rad text is also a link, I need to copy the number portion)

My console is stuffed with errors of firefox trying and failing to send telemetry pings.

Hi everyone,

Prior to the release of Firefox Desktop 133.0, which I believe came out today on 11/26, I was using the profile switcher that was in the Firefox application menu. I had all my profiles created in about:profiles and I had browser.profiles.enabled set to true. This allowed me to easily switch between profiles by pressing the hamburger button in the top right. However, it is no longer appears for me after the latest Firefox update. I'm not exactly sure if I'm missing something, or if this was intended as I know the profile switcher was a work in progress feature.

This reddit post shows what the feature looked like. I will also attach the images.

If anyone would know why this no longer appears to be working, or how to fix it I would greatly appreciate it. I know I can just use about:profiles or some other alternative, but I found this to be the most convenient.

Clicking on any article at ncronline results in just First Letter of text appearing. Some links appear as well. This occurs at no other site. Using EDGE, I have no problem at the site.  ??

Hello.

For the past few months, I've been experiencing severe issues with performance that I noted appear only on YouTube. I have not noticed this on any other website. The site is unresponsive, takes a long time to load, key presses (pause, skip 10s, etc.) are registered with a massive delay. It is generally very unpleasant to use.

I have tried disabling all extensions, clearing data, I even reinstalled the entire operating system once for a different reason and the issue still persisted. I launched YouTube on different browsers (Chrome) with no performance issues at all.

I lived with this problem for a long time now, but recently it's becoming unbearable. I prefer Firefox to Chromium-based browsers, but as YouTube is a site I visit very frequently, I will unfortunately consider switching to another browser.

I have not found any useful resources regarding this issue on the Internet, it seems like it's not a common problem.

Any help is appreciated.

I have been playing a word game on Gamepoint.com...always worked. 3 days ago when the gameboard comes up it is messed up. I jumped onto microsoft edge and it works... firefox is having issues letting this game load properly...how do i fix?

Are there any plans to make configuration of the setting "network.proxy.system_wpad" available via ADMX (grouppolicy under Windows)? We need to deploy this to 100 computers ans I still have no idea how.

Feature was introduced in FF 125: https://support.mozilla.org/en-US/kb/firefox-enterprise-125-release-notes We currently use 128.4.0esr.

Thanks, Torsten.
