Today as I got to work (Windows 11 machine), I had a suspicious Firefox.exe file on my Desktop, it was not a shortcut, but exe file. I did a little investigation and research, and I noticed some difference from Program Files exe file and Firefox.exe on my Desktop:

C:\Program Files\Mozilla Firefox\firefox.exe

Size: 695424 bytes SHA-256 hash: EEB242895F8ED48B43EAAA9ECA06C6DDE54425F8AE0E16200D2D46F839B9A540 File version: 145.0.0.327 Copyright: ©Firefox and Mozilla Developers Date modified: 16.11.2025 12:35 Original filename: firefox.exe Digital Signature: Mozilla Corporation

and Firefox.exe that appeared on Desktop

C:\Users\User\Desktop\Firefox.exe

Size: 389248 bytes SHA-256 hash: E8DA5735FE1B5E92BA3636B8D17B5BEC0EA521DB6A8B5A52177FF3E8B2F60710 File version: 145.0.0.327 Copyright: Licence: MPL 2 Date modified: 16.11.2025 12:35 Original filename: desktop-launcher.exe Digital Signature: Mozilla Corporation

I scanned both files in VirusTotal, and they both seems clean and legit

I uploaded both files to:

https://drive.google.com/file/d/1kALgQbfhIpHqs1pN6dmTdF71nm10LlD-/view?usp=sharing

Can somebody assure me that both files are OK, and can somebody explain to me why Firefox.exe appeared on my Desktop, and why is there difference between two files in size, Copyright info, and original filename ?

More of a comment. Firefox is the only browser I have used. Love it! Many important bookmarks to easily navigate. Broser update messed up bookmarks and took me hours to get back! Found. Save key and/or password! Learned a lot about profiles and Firefox along the way. Ugh!

On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

I just bought a new computer. How do I sync firefox on my old computer with firefox on my new computer. The same for thunderbird mail. Please help. I am not a computer genius. Dave Muran [edited email and phone# from public community support forum)

When I try to "sign into" Firefox using Google Chrome, I see the following message: "This account is not active. Please contact an administrator if you believe this is an error." I do not know how to contact an administrator. I do not see this statement when I sign into Firefox using my Firefox browser. Maybe (I think) the issue is that I need to use my Firefox browser to "sign into" Firefox (and, not Google Chrome). Thank you for your comments about this.

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me?

TV will not play programs. It brings up the app but when I select a specific program I get "We are experiencing problems with our servers. Try again later". It works fine on Opera,Edge and on iPhone. I noticed that Firefox does not store my location in the same place as other browsers and wonder if that is the issue.

I am looking to find a way to change the time in which I receive updates from Mozilla. Getting an update interferes with the operation of my laptop and to top it off, I don't know that there is an update coming through so I waste so much time thinking I have a problem with my connection, my router, my settings, my laptop. Hugely inconvenient. Why can't I set the time I want updates to come through and not interfere with me while my laptop is in use. This is enough to make me want to drop Firefox and switch out.
