Well I am on the near end of Support for Windows 7 SP1 Pro here for Firefox 107.1, and very similar with me, instead of Stop Errors, I get complete Computer Freeze ups, and don't have Hardware Acceleration enabled on it, but I did some Evidence that the Freeze ups maybe due to too many Firefox processes running and apparently causing some issues of PID handling which is causing which I did a test and found out CSRSS.exe maybe having difficulty with the Multiple Firefox Processes in some versions of Windows 7, 8.1 & 10, last known problem was discovery of the Win32K. sys Lockdown Exploit which to some note is also Security Exploit.

I recently updated to 129.01 (64bit). Now Firefox keeps crashing, especially when I am trying to fill out an online form. Does anyone else have this issue? Any suggestions on how to resolve?

I have used Firefox as my preferred web browser for years. Following an update a couple of weeks ago, Firefox no longer starts. Instead I get the following error message:

XUL Runner Error: Platform version '127.0.2 is not compatible with minVersion>=127.0.1 maxVersion<=127.0.1

My OS is Windows 10.

I would be most grateful for any advice on how to regain access to Firefox.

I want to insert my new IMAP or Pop email box into Outlook. I was already told that this email box@ sophie.johnson@proofreadereditorwriter already exists. I could not get it to show. So I deleted it, and I want to start afresh to install it.

Receiving the following error message:

Error: Platform version '129.0' is not compatible with minVersion >= 128.0.3 maxVersion <= 128.0.3

How do I resolve this?

My Firefox install apparently did a background update that did not complete, I get an error 'XULRunner / Error: Platform version '129.0' is not compatible...'

I did not (do not) have a profile I had logged into for that installation, but did have many passwords saved that I'd like to still be able to use if at all possible.

I have installed another instance of Firefox that is working (on platform 129.0), and am using Windows 11. I also turned off automatic updates in hopes of preventing this in the future.

The previous profile still exists in AppData/Roaming, but I don't know how/if I can connect it to the new installation I now have.

Is it possible to either fix the incomplete update or connect my old profile to this new instance so I don't have to reset all my passwords?

Thanks!

I'm having trouble posting here with that error message, and problems uploading images, so forgive me if you have not seen the latest updated post.

You are still on the beta update channel as you can see in the "Help -> About Firefox" screenshots.

You can possibly check about:support for the path of the Firefox binary and profile folder..

Above you mention portable, are you using a portable Firefox version? To update, it's just a matter of extracting the executable and replacing the contents of the portable folder.

What differentiates the "portable"method, that I've been using as my method for years without an incident, up until recent recent Firefox releases? The only thing I do when there's an update is replace the contents of the install folder, the same folder that the profile manager is pointing to, with the contents of the extracted executable,

I just realized the existence of this folder in about:support "Update Folder: C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\C47CD37E750B0BD0. I tried to delete it. It recreated itself, changed my settins to "Update Autoimatically" and wiped out my entire session.

The contents of it's update-config.json file are the following. Would changing these values to "false" do any good? Or perhaps altering the contents of updates.xml in the same folder

"{"__DEFAULTS__":{"app.update.auto":true,"app.update.background.enabled":true},"app.update.auto":false}"

I do have a "Profile" folder at C:\Users\mr\AppData\Local\Mozilla\Firefox\Profiles. The two entries are from 2019. One is empty, ans these are the contents of the other

profile contents

Since the last update (was executed today in my case 16-07-2024), firefox has been very slow and freezing and crashing. Also, somehow it is the only browser that can't handle yahoo finance new charts and keeps freezing....so many issues in a short span of time, please check. I have tried other browsers and things seem to work fine there, so, it is not my computer or OS.
