Firefox Community Forum

A couple days ago when I opened Firefox, I immediately started getting pop up messages saying I had viruses. If I clicked on REMOVE VIRUS, it tried to get me to sign up with McAfee. I cannot see my full screen due to all the pop up screens. My MS Defender virus protection is not identifying any viruses.

When viewing a PDF in Firefox the URL bar indicates the file was downloaded to a temporary folder. If I then select "Save" from the PDF toolbar; or if I right click and select "Save page as" it opens a save dialog to the location I previously saved the same category of PDF to. For example I have separate folders for invoices, if the PDF is my electricity invoice it somehow knows and opens the electricity folder. If it is a water invoice, it automatically opens the water folder.

Whilst this is indeed quite handy, I do not understand how Firefox is doing this; nor do I understand whether this may be a privacy risk in some circumstances and should therefore be configurable.

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

Hiii, I am using Floorp 12.16.3@153.0 on Debian 13 with KDE Plasma. Since the latest update, navigation from Floorp’s Private Container no longer stays inside the container.

Steps to reproduce:

1. Open a new tab in Floorp’s Private Container. 2. Type either a URL or a search query in the address bar. 3. Press Enter or click the arrow button. 4. Instead of loading the address in the current container tab, the browser creates a new regular tab outside the container.

The new tab does not show the container indicator and uses my normal browsing cookies. However, clicking one of the shortcuts displayed on the new-tab page correctly loads the website inside the Private Container.

I have already tried the following:

• Confirmed that `browser.urlbar.openintab` is set to `false`.
• Confirmed that `browser.search.openintab` is set to `false`.
• Restarted the browser.
• Disabled Floorp Start.
• Opened `https://example.com` inside the Private Container and then entered another URL or search query in the address bar. It still opened a new regular tab.
• Tested by pressing only Enter, without Alt or any other modifier key.

Expected behavior: entering a URL or search query should navigate within the current Private Container tab.

Actual behavior: a new regular, non-container tab is created.

This previously worked correctly and appears to have started after updating to Floorp 12.16.3, based on Firefox 153. Is this related to a change in Firefox 153’s container behavior, or is it likely to be a Floorp-specific bug? Please help, I'm a huge floorp fan :(

Similar names for Connected Services make "Send to Device" on Android unable to differentiate devices. The workaround is to "send to all devices". I can change my device names but I don't know how to change the Connected Service name. Here are some:

• * * geoffrey’s Firefox on Geoffreys-q551ln-ASUS-Laptop
• * * Gwheeler’s Firefox on GWHEELER-SM
• * * Firefox on asus ASUS_AI2202
• * * Geoffrey’s Firefox on Geoffreys-iMac
• * * Firefox on samsung SM-G781V
• * * gwheeler’s Firefox on GWHEELER-LT-SM
• * * Firefox on SM-G960U1 Santa Maria, CA, United States

How can we improve this? Abbreviate Firefox to "Ff"? Use an in-line Firefox glyph? Also, I have a dualboot and run Lubuntu and Windows from the same device. I wonder how I can handle the device name to differentiate which OS I'm logged into.

I’ve been taking a look at the latest updates regarding the new Firefox design rolling out in Nightly, and while I appreciate the ongoing work and the return of features like Compact Mode, I wanted to share some thoughts from a user perspective, particularly regarding the aesthetic changes.

Personally, I’m not a big fan of heavily rounded edges across tabs and UI elements. For my workflow and visual preference, I much prefer a cleaner, sharper, and more traditional layout.

With these UI evolutions coming down the pipeline, it would be fantastic if Mozilla could provide a built-in option or setting to keep the current/classic style intact while still receiving all the important under-the-hood updates, security patches, and features. Giving users the flexibility to choose between the new design language and a more traditional layout would ensure everyone can tailor Firefox to their exact liking.

Would love to hear how others feel about the new look and whether a classic style toggle would be a welcome addition for you too!

Hi. I'm taking an online course for HVAC certification. Some test questions require to arrange the answers in a logic sequence. When I try to move the answers up or down, they 'snap back' into the original (wrong) position. Is there a solution to this issue? I'm using FireFox with Linux Mint Cinnamon.

Greetings, Matt

Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I'm running Linux (NixOS) and Firefox version 148. I've tested on Chrome based browsers and they work fine. Tested on Firefox forks and they also don't display correctly. This is new since less than a week ago.

Thanks for any help with this.

Firefox 150.0.1 Ubuntu 22.04

Problem: When downloading a file from a web page, the list of files and folders in the Download Panel are sorted such that file names and folder names are intermingled, rather than the "standard" folders first, then files.

Discussion: This problem has been happening for a bit now (probably 2 - 3 months or more). Unfortunately, I don't recall exactly which version of Firefox this originally showed up in. At some point recently, the default sort for the Download Panel changed, so that instead of listing folders at the top of the list of download targets, then listing files, now all items are interspersed. For example, previously selecting to download a file from a web page would give the Download Panel contents as:

AFolder BFolder CFolder AFile.txt BFile.pdf CFile.jpg

Now, the list presents as:

AFile.txt AFolder BFile.pdf BFolder CFile.jpb CFolder

I would like to go back to the previous sorting behavior, but I cannot find a way to do this. I have searched the Mozilla help articles without turning up relevant information, and I have searched the internet for web sites that might list relevant information, but either the information I am seeking is not out there (unlikely) or I am not coming up with search terms that locate the information (much more likely).

I am not even 100% sure that this is a Firefox problem (it is within the bounds of possibility that it is an OS problem), but none of my other regularly used programs show the symptom, so it would seem odd to me for it to be something other than a Firefox problem.

I would appreciate any pointers (web pages, help articles, or even just "change this in about:config) on how to resolve this.

bonjour,

j'utilise le VPN de firefox, j'ai compris ou trouver la consommation de données mensuel, seulement elle n'apparait pas dans la rubrique vie privée et sécurité des paramètres!

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

I sent an email a few days ago asking for a refund and a few hours later changed my mind, I couldn't cancel the ticket (as far as I know) so I sent a follow up email to disregard the first email because I thought it would just be more hassle and I think the VPN works fine anyway. Today I get an email saying my subscription had been cancelled! which I could understand is my fault for being indecisive in the first place and the last email I sent might not of been read in time, but the email that I had received also didn't state I would get a refund and seemed like an email I would get if I had cancelled my subscription myself stating "We’ve cancelled your Mozilla VPN subscription. Your final payment of US$59.88 was paid on 14/07/2026" Should I still expect to get a refund or was there an error with my request?

Using the "re-open tab" function on a browser based discord instance changed a bunch of my settings, for one it turned on vertical tabs, added extra side bars to everything, and made every ui element animated. Ive figured out of how turn vertical tabs back off, and while I was writing this, I figured out where to turn off this stupid animated gizmo to select what I actually want, instead of directly bringing up my bookmarks/history. How do I stop a random website from overriding my settings in the future? If discord can do it through incompetence another website can surely do it maliciously and I really dont fancy this happening again. The "best" (and completely unrelated) I've found on how to undo this, let alone prevent it from happening again is pressing esc or f11 because of course everything these days has to drown in AI slop :/

Iam getting statements saying someone living in same town as I getting on my account with a Linux or android what is Linux representing and when they say android with one ?? I have 3 different thing's i use but I never use a computer. Lap top or desk type???.

"Recent changes in how some corporate web sites react to FireFox such as not show the header menues and other function reduction in the last three weeks. YET Chrome and google still function like normal. Is this an attack on Linux supported browsers? " I contacted United Health Care (UHC) regarding their menu disappearance and treated it like error on my end until I discussed doing their recommend fixes and the only ones that worked are going to other Google or Micro-Soft supported browsers. FireFox was working fine until three weeks ago. What's up, is it FireFox or UHC?

My Dell Precision Laptop from 2019 runs a frequently updated Ubuntu 24.04. About one or two weeks ago, after one of the latest Firefox updates, i noticed that video streaming produces rectangular flickering in rapid sweeps. ( Also fast scrolling large text websites produces similar flickering, I think I would have noticed it before...) . If you detected it once, you see it always again... :-( First I fiddled around with the nvidia settings because the driver was also recently updated, without much success. Playing locally stored videos, e.g. with VLC media player, still works fine, so the nvidia driver is not the problem i think. Yesterday I installed Chromium and the video performance is fine! As good as with firefox some weeks ago! So it must be one of the latest updates, that causes the problem. Generally I like firefox more than chromium. I like the control you have, e.g. via Add ons.. So I hope that the firefox performance will increase again... Thank you for firefox! Florian Mengedoht
