Firefox.exe -silent and Firefox.exe -silent -p default work, but Firefox.exe -silent -p MyProfile Not

Do it is possible to preload Firefox with a custom profile with extensions, without stay visible, to speed firefox istance open?

-os-autostart What exactly does it do?

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.

Hello everyone,

I have a problem. I have seen that there have been discussions about this in the past. Unfortunately I have not found a solution and the discussions are all archived.

Now to the problem: Various pages have no favicon in Firefox when I drag them into the bookmark bar as a bookmark. However, when the page is active in the tab, a favicon is visible there.

The problem does not seem to be unique to me. Several people have tested it. It also seems to be a problem in Firefox only. In other browsers, this problem does not occur.

What can website owners do to fix this problem?

Here is an example of a site where I have the problem. www.organspende-register.de

Many thanks in advance. Best regards

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.

Sometime in the last few months, Firefox (Developer Edition) stopped allowing redirects and links to file://-protocol URLs. Is there a way to re-enable this for my personal browser, e.g. via about:config or the like?

Thanks!

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.

My (custom) cursor has recently started being transparent when I hover over a YouTube video. On darker colors it's fine, but on white it's straight up invisible. I tried recording it, but the recording doesn't capture the transparency. This didn't happen before, I changed nothing.

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.

Firefox version 128.0, on Windows 10 Home v 22H2

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.

I use Mozilla Firefox browser on my work laptop, and have it Sync'd to my iphone. Yesterday my sister opened Firefox, logged me out, and logged herself in, to access some things. But instead of closing my profile (bookmarks, saved PWs, etc.) it MERGED hers with mine. Now, on our laptops and phones, we see each others bookmarks, saved PWs, etc. How can I unmerge them? Pls help!

I have browser.messaging-system.whatsNewPanel.enabled set to "false". And yet when I update firefox, there's still a new tab opening telling me useless information.

I don't want firefox to ever automatically open a new tab ever, for anything, ever. I don't care what's new, I don't care what changed, I just don't care. I want to permanently and completely disable firefox from opening a new tab to tell me literally anything.

Please don't try to argue or convince me otherwise. It's such weird and rude behavior. Just please, how do I disable this feature that is annoying to me?

Firefox should never be able to open a new tab on its own. Any tab openings should be done by user action.

Hi,

There was some kind of Firefox upgrade today that has just thrown everything into chaos. I have tried to recreate my tabs--they don't show up in my history--and have done okay with that. My google scholar extension button, though enabled, doesn't show up. I don't know wtf happened but it is all a literal headache.

I'm the last person I know who still uses Firefox--this may be the last straw.

Hello,

I was having a problem recently with blue screens of death so I had to factory reset my PC - but not before backing up my personal files to an external hard drive.

Upon re-downloading Firefox, my saved passwords have pulled through with my profile (thankfully) but my bookmarks have not.

Am I missing something or should they have pulled through too?

I've tried the obvious like "Manage Bookmarks -> Import & Backup" and also looking for the file manually in AppData\Roaming\Mozilla\Firefox\Profiles\q6xxdvnd.default-release\bookmarkbackups

If anyone is able to help, it would be much appreciated

cheers
