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

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

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.

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.

Hi there

since the latest update (17/1/23) Firefox seems to Hang then lockup then freeze then unfreeze when just browsing.

no special tabs open such as Youtube- just locks up on browsing 2 tabs plus- google search on 1 and facebook on 1 tab-closed the google search tab then scrolling through Facebook,froze after 3 scrolls of the wheel,locked up then unfroze

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.

Win 7 64 bit. 109.0.1 (64-bit) I have two admin user accounts. On number two when I bookmark a page it automatically puts a folder on the toolbar.

in number one it puts in the bookmark pull down [where you click Bookmarks from the menu bar] and I can create a folder on the toolbar if I want. I want.

I do not want all boomarks to be on the toolbar but want the toolbar shown as i want to be able to add a folder

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!!

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)?

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

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.

When browsing in some websites such as "facebook.com", "mozilla.org", "lenovo.com", I sometimes get a popup to this link, but I don't have any kind of extension that could be causing that I think. What would be a way to troubleshoot this so that I can prevent that from happening? It's really annoying and the site also seems really sketchy.

I lost my tabs. Firefox has been opened and closed several times after losing tabs. I went here https://www.jeffersonscher.com/ffu/scrounger.html. I was able to find the file containing my lost tabs, it is sessionstore(1706800631216_9931f324-5558-4488-a36c-a5b3cb9e8c54_event_jsonlz4).json What do I do with this file now? Thank you.

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?

Hello, Not sure exactly where the problem lies with this one. We have a local UrBackup server running, exposing its http-only web interface on http://hostname.local.domain:55414.

I can no longer browse to this address, Firefox responds with

Secure connection failed and the error code SSL_ERROR_RX_RECORD_TOO_LONG

Looking at the GET request, the scheme is set to https and there is only one request, no redirect.

I can however access the site fine by IP, http://192.168.x.x:55414, AND, by using hostname only, http://hostname:55414, letting Windows fill in our DNS suffix as the network is in an Active Directory domain.

I also have a local Apache server running on my machine, only listening on http on standard port 80. Accessing http://localhost is fine, accessing http://myhostname is fine, but accessing http://myhostname.local.domain again causes FF to switch to an https-request.

What makes me confused is that this behaviour is consistent across browsers, Edge, Chrome, Android on my mobile...

Using Bitdefender for AV/FW, disabling it makes no change.

Tried downloading an older version of Firefox (89) and it does NOT show the same behaviour, URLs load as plain http.

Finally, I tried to add test.subdomain.com as a zone in our DNS and add an A record for the IP of the UrBackup-server, and voila, Firefox requests that site as http without complaining!?

Has the global browser market collectively decided that non TLD:s can no longer be accessed using http, or am I overlooking something obvious?

Best regards Alexander

EDIT: I originally included "false HSTS-requests" in the subject, before realizing that this came from FF redirecting to 443 on my local machine, which has a docker instance listening on that port but using a cert for our public domain, not our local one.

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.

The free version allows for 5 masks. Is that 5 lifetime masks or 5 active masks? Example: If I set up 2 masks I have 3 remaining. If I delete one of the set up masks do I now have 4 remaining or have I still used up a mask even though it was deleted giving me 3 remaining? Thanks

When changing the primary password I would expect the logins.json file being rewritten with new pairs of encryptedUsername and encryptedPassword (now encrypted based on a new primary password). But this is obviously not the case. But maybe I just didn't understand the way this works?
