Whenever i send a Tab from any Device to a Linux Desktop, the Linux Desktop is almost guaranteed to freeze. It doesn’t matter if that Linux Desktop is my "Dingus" PC with 2GB RAM and Wayland, or my "Workstation" PC with 16GB RAM and X11. On both Desktops, Firefox runs smoothly until it gets sent a Tab from another Device, then the whole Linux Desktop freezes. The Desktop doesn’t slow if i open the Tab on the Desktop in the “Tabs from other Devices” Sidebar instead.

Only my Linux Desktops freeze when they get sent a Tab from another Device. Android doesn’t slow when my Phone gets sent a Tab from another Device.

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.

Over the past few weeks, my typing is continually being interrupted. It did this a few years back, but this is getting very annoying and I am soon to switch browsers if not fixed. BTW on any machine using Firefox, this is happening

A radio station https://www.wfmt.com/schedule/ that has run successfully until today in Firefox no longer does, There is momentary blip of sound but then silence. It runs fine in Chrome. Another station continues to run successfully in Firefox

Hello! I can't login to my x.com account from Firefox 115.35.2esr on Windows 7 SP1. I'd was stay logged in many years before I accidentally clear my cookies. And now I can't login. It just reloaded input form when I type my login and press "Next"button. I tryed login from Private mode, I tryed to disable all addons. Nothing helped. But I still can login/logout from Firefox 140.10.2 on Windows 11.

In Firefox console I see

errors [ {…} ] 0 Object { code: 399, message: "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1" } code 399 message "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1"

and

Can anyone help me to fix it?

FF for Linux Mint mint-001 1.0 FF closes in just a couple of minutes, even with one open tab and nothing clicked or typed. FF crashes even in "Troublshooting Mode". "about.crashes" lists no crash reports Using Task Monitor to view system vitals, I discovered that while CPU usage by FF is very low, memory usage rises linearly over a couple of minutes. System memory available is 31.0 Gb. When FF usage reaches 30.7 Gb, FF crashes. No other browser or program has issues.

I use multiple Firefox profiles and create separate desktop shortcuts for each profile using Firefox’s built-in profile shortcut option. I then pin each profile shortcut to the Windows taskbar so I can launch them independently.

The issue is that when I click one of the pinned profile icons, Firefox opens a new separate taskbar group/icon instead of attaching the window to the already pinned taskbar item for that specific profile.

For example:

• I pin Profile A and Profile B separately to the taskbar.
• When Profile A is already open and I click its pinned icon again, Windows creates another Firefox taskbar button/group instead of reusing the existing pinned Profile A button.
• Google Chrome profiles do not behave this way on Windows — each profile stays grouped with its own pinned taskbar icon as expected.

Is this a known limitation/bug with Firefox profiles on Windows taskbar integration, or is there a way to make Firefox profile shortcuts behave like Chrome profile shortcuts?

I use the current version of Firefox on Ubuntu 22.04 Linux. When I scroll down past the individual bookmarks at the end of the menu, the folder names start repeating, along with the bookmarks inside them. I have three or four sets of bookmarks and would like to have only one. How can I delete all the bookmark folders below a certain point? By the way, when I install a new, different version of the operating system and sign in Sync restores all the bookmarks.

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

I thought I used to be able to access browser history from much longer ago, either way I can no longer see any history longer ago than 29/10/2025 is there anyway for me to restore, download or access older history, or has it been permanently deleted? I do still have a back-up of 28/12/2025 but I don't know if or where that contains history. I'm looking for data between 2019-06-01 and 2024-08-21. Weird thing is I remember accessing search history that old before... though I'm not sure how if if it doesn't store it for that long. Any help would be appreciated.

How to sort Tab Groups alphabetically in the Add Tab to Group Menu?

I want to add tabs to groups bit the groups are changing their position and it would be very helpful to (optionally) have the freedom to sort Tab Groups to appear alphabetically in that menu!

But that should NOT affect the sorting order in the browser window!

But of course it also would be helpful to have the freedom to also sort the tab groups order in the main windows, but please make it a different sort order than in the Add to Tab Group menu dropdown.

Thanks!

i've seen this before, in different older machines, but i can't remember the remedy. possibly a mouse-screen problem. it started with 150 i think...

Also in youtube, a gray layer covers the selections rendering mouse clicks impossible. clcking the logo, page reloads, but soon the layer covers most of the page. resetting graphics had no result.

thanks

i'm using mf 150

Good evening,

I'm going to install the applicatioin because it hasn't been working for several monnths ( it doesn't work anymore ). For exemple , if I want to watch Netflix and the video starts playing , there's no picture, it just loops and the screen is black.

I've tried everything turning off the computer, closing Netflix, even Youtube . I'm at a loss.

Thank you

Firefox FREQUENTLY totally removes added applications attached and it totally screw up my ability to access anything when you remove my Bitdefender application from access then I have to again EXPLORE added applicaitons!!

When changing tags in Microsoft 365 Term Store, the changes are not showing on the respective Sharepoint sites and lists when displayed in Firefox. The tags still show the old values. Refreshing the page and deleting the cache does not solve the issue. Only uninstalling and then reinstalling Firefox resolves the issue. The problem does not occur in Microsoft Edge.
