Firefox Community Forum

Hi,

Following downloading update version 146, I have been unable to open Firefox, all that happens is that a box appears stating (see images): firefox.exe - Bad image, then C:\Program Files\Mozilla Firefox\xul.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000000d.

After clicking OK on that box another one pops up stating:

Couldn't load XPCOM.

I have tried doing a Windows system restore, to try to take it back before it downloaded version 146, but this hasn't worked.

I've looked online and followed the advice there to download Firefox from your website, but that failed, just generating the XPCOM error.

My MAIN CONCERN at this point is that I do not want to lose all the bookmarks I had saved on my Firefox! I can't see any file within those in the Program Files\Mozilla Firefox folder, so is there any other way to save\recover them?

I don't have any original "installation media" so as far as I can remeber Firefox was pre-installed on my PC?

I have a Samsung PC running Windows 10. There are two Mozilla Firefox folder under my C:\:

C:\Program Files\Mozilla Firefox and C:\Program Files (x86)\Mozilla Firefox, under this folder the version is 146.0.0.383, but under the other folder it's version 145.0.2.579?

Please advise as to how to save my bookmarks and rectify this error.

Thank you in advance.

A couple of updates ago, I received the message that some of my bookmarks will not be available. So I ran through the trouble shooting FAQs and I ran into a problem. When I go into Manage Bookmarks and it brings up my now empty library, when I select Import/Backup then Restore, it will not show me any files to restore from. Additionally, I used Fx File Utilities and it show the corrupt entry that I cannot remove, but allows me to export the json file to an html file so I can import it, but once again, when I select Import from HTML, it shows me no available files to restore from. Lastly, I imported the html file in to Chrome and then tried the option to import from another browser, but again, it will not allow me to select anything.

I have confirmed the integrity of the db as instructed, etc. So I have run out of options. How can I get my 15+ years of bookmarks back?

some of my icons on the location bar do not appear, or only appear when I have the window maximized. How can I reorder thewse icons so the ones I want to see most often are on the left? this refers specifically to the add-on icons, but I would think all the icons are controlled the same way (that is, if one can control them).

I went through the process of importing all of my old profiles into the new profile manager and I, for one, am stoked that we are joining the big leagues with regards to profile management. This has been a feature that I have been waiting for for quite some time now. I have an extension that allows me to easily switch between the old profiles but a proper, built in solution was necessary.

That is until I launched Firefox the next day and was greeted with my work profile instead of my personal profile. I started digging through the settings and it seems that this is the intended default behavior for profiles. The last profile you had open is the profile that will open by default.

It's fine if the developers want that to be the default but what I also find strange is that I cannot, for the life of me, find a way to change this behavior on Windows. I found it on Linux (I think??) but I dont see a flag for it in the usual places. Maybe I missed it. That is why I am here.

1.) Is there a way to change this default behavior for the new profile manager? 2.) If not, can we plan to add that feature? Currently, this behavior makes the new profile system unusable for me because I need my browser to open to my personal profile when I open a new window.

I click on the top right button and choose password button. And I can't see any password I saved before. I have no idea why this things happened. Right now I couldn't see the password that I saved, but I can use the password when the firefox tells me I have saved one. I still need to see the password because I saved some password that I use for other platform on firefox. The screenshot attached below. what should I do now?

In settings there exists the option

"Open Firefox automatically when your computer starts up"

I have specifically chosen to disable this option; there's nothing wrong my hand.

I am perfectly capable of moving my mouse pointer to the Firefox icon and clicking it when I need to; and running on a decent spec machine with a late spec NVMe drive, the startup is near instantaneous.

I don't need or want additional Windows boot clutter.

Nevertheless Firefox periodically nags to enable this useless setting option like I maybe don't know it exists. How do I stop that ?

Whilst it's not every time I start it, I recently reinstalled Windows 11 barely a month ago. I've already been asked 3 times.

On modern systems running on high spec storage devices this seems like such a pointless option, but to even repeatedly try to push people to use it when they don't want to seems somewhat disingenuous.

Given Ramageddon where people are having to build systems with lesser amounts of RAM it seems even more unlikely that people are going to want bulky applications that they may not immediately need to be auto-loaded every time they boot their PC, before they will be able to use their pc for whatever they switched it on to do.

Is there option to disable these "helpful" suggestions ? Thanks!  :)

When a PDF document is dragged into Firefox, you get an app that allows you to write on it, import images, highlight, etc. However, if I use grouped tabs, you cannot use the app anymore. It will not write on grouped. I'm not sure where this issue would fit in the options provided. Thanks for any help you can give.

i am trying to type this message on firefox, but i have to avoid shift key not to interrupt typing. when i hot shift+some other keys like i, b, v, etc, devtools pop up. i have checked other forums, other q&a on firefox support, and concluded that the same issue have occurred to many users regardless of the os, features, extensions, various keyboards (but not the virtual one for me) or system settings. i have to type a lot in the browser, so i just choose to delete firefox until someday the issue is fixed.

I was unexpectedly signed out of my account. I used my encryption key to sign back in which i have done before. I have never experienced this problem before. This time when i logged back in all of my saved passwords were gone. Is there any hope of fixing this issue?

When my laptop is connect to a monitor via HDMI cable, the resolution on Firefox switches between what my laptop is at when not plugged in and the current monitor's resolution. It almost looks like Firefox is hiccuping between resolutions. This last for a few seconds and happens frequently within the hour. How can I stop Firefox from being confused about the resolution it's supposed to be at?

When I load a pdf into Firefox, a pdf app opens at the top so I can write text, add an image, etc (thanks for this). Lately, when I am using the app, it will stop working randomly no matter which button I am using. If I'm suing text, it will stop and not allow me to select anything. If I'm using the highlighter, the same thing happens. I tried removing all my extensions but that did not work. I know this started after a Microsoft and Firefox update. Could you please fix it, otherwise I have to use Chrome and I hate Chrome. The app controls are on the far right of the image.
