When I open a .jpg file, the Firefox web browser window width is too big. I want to change the default window width. Which item in about:config controls this setting and what value should I enter to have a default window width of approximately half the screen size?

my Firefox was working just fine, and I did an update this morning and now nothing works. My Firefox will not install and nothing that works with Firefox will work. I tried to uninstall the Firefox that I had and it doesn't even show up on the list of programs any more, so I can't do an uninstall.

I'm having a difficult time logging in. I probably need to get started all over again. I locked my self out by too many attempts to log in. I'm totally lost and probably need to start the process all over again.

In my control panel programs and features I have 2 versions of Firefos GB and US. When i click on about in Firefox it does not show which version i am on GB or US. I want to delete US but want to make sure i delete the right one as I have bookmarks

Also when Windows starts up i get 2 Firefox browsers open. How can I get rid of the one I dont want as first one has my favs

On FireFox v115, on Mac system High Sierra, 10.13.6. Autoplay setting will not let me remove this 'about:welcome^privateBrowsingld=1' or this 'about:welcome' no matter how many times I try. The version on my Mac laptop,129, does not have this or anything. What is this?

I've always been able to type a new web address directly into my browser bar. Firefox no longer allows me to do that. It reverts back to the original address, even when opening a new tab to start over. I also can no longer type into the Google search box. It tries to take me to the browser bar instead, and then I can't go anywhere. Help please!

When I am on the Facebook app, after a while I have to sign in again, starting a question about accepting cookies. Also when I have started Firefox and I click on Facebook I have to sign-in again, before I clicked on Facebook and it was there. Can you please help me?

Hey,

So my Question is is there any way to prevent Firefox to change the Profile after Updating. Because i work in IT thats why the Security is a Problem so i cant just leave an older Version on every System. The Problem is the Customer dont want to change it everytime.

I would really appreciate it if someone has an Solution. 😊

Hi,

In the older Firefox version (92), I could instantly open JNPL files by selecting "Open with Default Use JAVA (TM)". However, in the latest Firefox version 127, while the option is still available, it doesn't instantly open JNPL files. Every time I have to click to open the JNPL file.

Hello. I got a new pc and I am trying to sync my Mozilla account right now but I am not getting a the code to my email so I can not login to the account. The mail in question is *@cock.li that I have all my old data on.

2 DAYS AGO I got an XUL error notice in my UP TO DATE Firefox. Tried turning on or off at times hours apart no use.

Getting by with other browsers in the meantime. But today At about 1:40 PM CDLST 15 August 2024

my computer locked up completely. Several dialog boxes stacked up and mouse and keyboard were ineffective it gave a virus name which I did not write down and a purported Microsoft number to call but I ignored it. Turned off my computer turned on and ran scan with Malwarebytes software NO INDICATION OF INCIDENT

The help page advice for XUL does not have the assurance NOTED AT BOTTOM.

IS THE FOLLOWING TRUE FOR ALL REMEDIES INVOLVING UNINSTALLING AND REINSTALLING FIREFOX? INCLUDING XUL ERRORS?

ASSURANCE The solution is to remove the Firefox program and then reinstall Firefox. (This will not remove your passwords, bookmarks or other user data and settings which are stored in a separate profiles folder.)

Lately I have been having low memory warnings, but still have some things I can dump to make room.

I came here to open a subject that I will address later, but the situation I just encountered here may be related in some way.

I clicked "Ask a Question" here, after which and the page opened to this.

I did not upload the two "uploaded" images you see at the bottom to this thread. They were actually used in my previous post, but immediately upon opening this post, they were already there.

I cleared cache and cookies, relaunched, but they still remain.

BTW. wasn't there a "Preview Post" option here before? Not now, at least for me.

EDIT: Now, after I just posted, the "Preview" button is there. But why, if there is no reply to preview? It's still not here in "edit" mode.

Most tabs that I open now crash. This has been a steadily building problem that now has made the system basically unusable. I did try clearing history, cookies, etc., but that did not help. Even working tabs can crash when I go back to view them. It doesn't matter if it is a saved site, or a brand new one typed in.

I've been using Firefox for years on Windows 10 and earlier, and I just got a new Windows 11 laptop. On the new machine my bookmarks sidebar doesn't persist. I launch Firefox and open it, but when I exit Firefox and launch it again the sidebar is gone. I have to re-open it every time. This is not the behavior I experience on my other machines. Is there a setting in about:config that I need to change?
