In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.

Hi,

I use ClassicPress (fork of WordPress) and I have a problem when requesting a password reset link for it.

When opening the email received to reset password in the firefox dev edition browser and click the reset link I receive an error stating that the link is invalid.

I discovered by trial and error that copying the same link and pasting it manually in a new tab of the same firefox dev edition browser solves the issue because then the link is recognised as valid.

This happened after the update I received last week.

I am a linux mint user if that helps in tracking down the issue.

... if this is even possible?

Has there been an influx of blue as the preferred icon color the latest years?

With somewhat degraded eyes, this has started to become a problem for me.

I want to have Firefox Developer edition installed, but I have to settle for the standard edition. Why ? Because the standard edition has a distinct orange icon. I am not able to quick glance at the task bar and see the difference between what window is Firefox Dev (blue icon), Outlook (blue icon), VSCode (blue icon), Azure Data Studio (blue icon), WebStorm (blue icon), 1Password (blue icon) or MS Edge (blue icon).

My problem is that my web browser (in this case Firefox) is the application I most often switch back and forth between and the struggle is real... I have to spend a lot of time looking at the task bar to acuatlly be able to see what icon is Firefox Developer Edition.

I don't need this as a feature in Firefox, necessarily, just some tips or tricks if there is any icons in the program folder e.g. I can swap out.

When playing any Ren'Py web build on Firefox Windows, the frames freeze while entering inputs. Depending on what is being displayed on screen, sometimes it will still continue despite the mouse movement, but most things just completely freeze up. Once the inputs stop, the frames will skip ahead to where they should be. This only seems to happen on Windows, as I was told it is not repeatable on Ubuntu using Firefox. This is also not an issue on Chromium based browsers.

OS Version: Windows 11 Home, 23H2 Firefox Version: 127.0.2

I have several virtual desktops: Desktop 1, 2, 3 and 4. Case 1: Assume that there is at least one opening Firefox window in any virtual desktop. And, if I try to open a new window in Desktop x (x = 1, ..., 4), it will appears in Desktop x as expected. Case 2: Assume that there are currently no opening Firefox windows in any virtual desktop. And, if I try to open a new window in Desktop 2 or 3 or 4, it will only appears in Desktop 1.

I am currently on windows 11 for ARM (surface laptop 7) and this problem is occurring with both Firefox as well as Firefox developer edition. It's also only happening on my external monitor. I have done some searching and found posts from as long as 4 years ago. The posted solution is to disable any compatibility options but in my case none are selected. This is driving me nuts, does anyone know of a solution? This has to be firefox specific because no other program does this, including other browsers. I have included a screenshot to show what it looks like.

Hello, Today I was writing a draft post on Substack and the screen refreshed every few seconds. Possibly when Substack was saving changes. Each time it did this, the screen would go blank for an instant and refresh, and then I would have to click to place my cursor where it had been.

This is new as of this week. I was not writing on Substack using Firefox last week.

thanks Chris.

Hi! When I bring up my Firefox browser it automatically shuts down and comes up again with two issues: 1. Do you want to restore pages? 2. A red striped URL with the little robot and the error message: browser is under remote control reason devtools

I've read all the postings and I don't understand many of what they are suggesting and those that I do, don't work. Please help p.s. I've already downloaded the newest version.

browser.cache.disk.enable, is re-enabling itself on every Firefox update. WHY?! I disable disk caching and SSL caching because I use a fast NVMe SSD and I don't want to use up all the write cycles to it.. cookies caching is fine with me...

It has been doing this on every update for a while now.. this is annoying and not ok.. please fix.

Fully patched Windows 11 on ARM Windows Surface Pro X SQ2

What I see: Misrendering of UI elements and some elements of webpages. Rectangular areas of all white with white on white text e.g. tab labels, settings page, etc.

What I tried. Uninstalling FF Reinstall FF Refresh settings

None of these fixed the problem for me.

Uninstalled Firefox Reinstall of Firefox

My system specs is as follows

i5-12400 32gb DDR4 3200mhz 250GB SSD as main (wd blue NVME)

Whenever I play 8k 60fps video on youtube it lags and get massive frame drops with igpu sitting at 100% usage. With other browsers like chrome and edge it works 100% can play 60fps 8k video without any issue.

Is there a functionality to view Tabs Side-by-Side, or Vertical yet? Or is there a plan for it; similar to the recent version of Edge Chromium? I have read several questions; and their work-around solutions of using a side bar or sing two windows and arranging them side-by-side. Neither functionality offers synchronized scrolling. I used Tile Tabs or We Tabs add-on in the past which was great.
