Firefox keeps attempting to access a web site with an unwanted application. The site is mv.outbrain.com and my virus software keeps asking to block the site. The popup is now becoming a nuisance how do I stop it or delete the reference to it

Well this happened after a Firefox Update with that i also suspect that using a User.js can aslo cause it would you like to look for the problem pls.

```js // /* You may copy+paste this file and use it as it is.

*
* If you make changes to your about:config while the program is running, the
* changes will be overwritten by the user.js when the application restarts.
*
* To make lasting changes to preferences, you will have to edit the user.js.

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

While I can click on the extensions button circled in the screenshot to access them, I can't move those extensions to the toolbar directly. When I search for this issue online, everyone says to use the customize firefox menu to add what I want, but as you can see in the picture - no extensions are listed there, although they are installed and functioning. Very weird because my other install, which is up to date, has this set as default and it has been forever. I'm bewildered. Any suggestions? Thanks

Dear,

I need to recover my Mozilla (Firefox) account on my computer after this latter crashed. Unfortunately, apparently I don't have the good password. Probably I used an automatically generated password which I don't remember.

I still have my account connected on my Android smartphone, but I can't access the account details (no way to recover my password or change through this device?!), and I can't export my bookmarks. Also, apparently all my identifiers and passwords were not synced on my smartphone :-( Hence somewhere all my precious information are available, but stupidly enough I can't access it anymore and resetting the password warns me that I might (is it even a certainty or a possibility?) lose everything. It seems that I cannot even produce a revovery key (to reset pwd without losing data as mentioned in the Help pages) as I can't connect on a desktop browser anymore (but well on my Android version). I am lost and just stupidly blocked - this is SO frustrating, I initially thought it would be a good idea to put everything in Mozilla - well...

Is there ANY way to actually recover my account without losing data on my desktop Firefox, given I still have access to the email account associated to the Mozilla account (and to the original emails from the creation of my accounts) and I still have access to my Firefox account on the Android app but this one doesn't seem to allow to do anything interesting in my case??

Thanks a lot!

I currently am running FF vers. 109.0.1 64 bit on Win 10 pro. I don't like what I've been reading about the latest update, my machines are old and I'm not ready to upgrade so I don't want an even more overloaded/uses up more CPU, etc., version of Firefox. I don't have complex needs in a browser, so some of the "upgrades" haven't been useful for me or have made using FF more difficult.

  I found a list of what I guess are older versions but no information was provided on how to choose a version of say v. 110, to make sure it's the right one for my laptop and/desktop (or the one that will work w/the fewest problems) that it's in English, etc.   
  My impression is that FF is mostly worked on by people who have a variety of needs & interests so increasing sophistication is what they want and that's fine, I'd like to keep using FF w/my current machines, w/as simple a version ,ie., useful for an unsophisticated user.    Is that possible?    If so, I'd like to upgrade to 110 64 bit or perhaps 111 64 bit unless either or both had huge security holes, etc and many users found they weren't very functional.   I do have security software.

Hello, The controls in Settings to choose how Firefox updates have disappeared from Settings / General? The "Firefox Updates" section is supposed to appear there, based on:

https://support.mozilla.org/en-US/kb/enable-background-updates-firefox-windows https://support.mozilla.org/en-US/kb/firefox-options-preferences-and-settings?as=u&utm_source=inproduct#search

This is on V109. I really need to be able to choose when an update goes in, Python / Jupyter applications I have running on Firefox can cost me hours of time to re-run if Firefox goes in and restarts itself when it wants to. I used to be able to control this. Has it really been removed, or is somewhere else and the docs not updated yet? Thanks Neil

Thankfully not too often are web site pages that are grossly out-of-format for my Android phone. Mostly everything is tiny. Yes, I can pinch expand or zoom in but then side back and forth scrolling is required to navigate and absorb the page. Not the optimum result. Very annoying.

I have font adjustments but those result in a similar and distroted page.

One web site option when available was a toggle for windows/cell phone that worked pretty good but it's not always provided. That implies the web site design is the formatting adjustment function.

Is the resultant cell phone display formatting a function of the visited web site, browser, phone device, etc or some combination of those entities settings?

Ever since Firefox updated today I've been unable to use the browser. It takes at least 5 minutes or more minutes to load, I can't manually log into any websites until the speeddial finally loads, and the speeddial addon refuses to come up for at least 5 minutes, I can't log into Dropbox even with the speeddial up and running because the capcha won't popup...and on and on.

What in the world has been done to it? I'm using another browser just to contact support.

The Bookmarks option cannot be found on the 3-points menu, con trary to the following help topic: https://support.mozilla.org/en-US/kb/manage-bookmark-folders-firefox-android#w_create-a-new-bookmark-folder There are several options like the following three, but Bookmarks is not there: Select tabs, Share all tabs, Tabs settings, etc.

What is this issue, and how can I manage tabs folders, please? How can tabs folders be managed like making a new tabs folder or rename it?

I have never used a primary/master password. I updated to 109.0.1 on a computer that had not been used for a few weeks. I do NOT sync FF on any computer. "Use Primary Password" is NOW checked on this 2nd computer. (never used or needed before) In order to try to change this, I was required to enter my password. When I enter the password I use to access mozilla support (the only FF password I have ever had), nothing happens and I do not get any options, i.e., forgot password. I have never been requested to enter a password on any computer (to access FF; only to reach mozilla support.) On my primary computer, "Use Primary Password" is not checked, as it should not be. Thanks in advance.

Firefox has started making a piercing high-pitched screech when the "save image" and "file update" panels appear. This is a confirmation or alert sound I suppose. It occurs when saving an image from a right-click menu and when downloading a file. Formerly Firefox used the system default sound for this, and that sound is still working in other programs for similar operations.

How can I fix this? Or alternatively how can I disable the sound during such operations in Firefox (or alternatively system-wide)?

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

Current situation: I have 2 monitors. I have the option of auto hide taskbar in desktop mode turned on. On the primary monitor, when I maximise firefox window( not full screen, the button between close and minimise, looking like a square), and hover my cursor towards the bottom, my taskbar doesn't unhide. However when I unminimise( clicking the middle button on the top right again), the taskbar unhides correctly. Also to note, my secondary monitor works completely fine ie, when firefox is maximised I can unhide taskbar on hovering near the bottom.

Firefox saves files that I only wanted to open with another application.

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.

I don't know why but sync button is not appearing in my Firefox settings (image attached). I guess it's because something I've done in settings that has cause this to disappear. Can you help me? Thanks!!

All of a sudden when I press F6, it starts a Google search (see image) instead of just focusing the address bar. This is rather annoying because I use F6 all the time to go to a different page (e.g. type "mail" and then follow the autocomplete to mail.google.com) and that doesn't work if it wants search google for mail instead.

How do I revert this to its normal behaviour?
