Firefox Support Forum

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

Did FireFox just officially do an Enhancer for YouTube...I got this on my Firefox screen. List 'what's new' and asks for donation...don't mind donating but is this a scam message or is it from FireFox?

I recently updated many drivers on my Windows PC as it was running very sluggish. I ran CC cleaner on it and updated 6 drivers including the Graphics card and several others.

Now Firefox browser will not launch. I have installed the latest version of Firefox also.. 127 I believe it is.

Any ideas on how to get it to run again?

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

I've recently had trouble logging in to some websites but not others, most recent example is Bandcamp. My login credentials are correct and work on mobile and other browsers. I have tried deleting my cache and cookies to no improvement.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

When editing one of my videos and trying to drag and drop a custom thumbnail after clicking upload file, I get a red circle with a slash through it on firefox indicating that this is not permitted. I am running firefox 127.0.1 (64-bit). I've tried uninstalling, running in troubleshoot mode and nothing works. Firefox is not running as administrator and my UAC is set to always notify.

On Chrome Version 126.0.6478.61 (Official Build) (64-bit) this feature seems to work as expected. Is this a firefox feature that may be preventing this drag and drop behavior? Please see attached gifs. I am on Windows 10 v22h2 btw -- Any feedback is appreciated.

The 'Manage Bookmarks' you have placed at the top of the page is doing exactly nothing. I can't restore them, they are gone. How do I get my bookmarks back, or restore to the previous version where they are still located. Sick of constant updates that just cause problems-about to go over to Edge.

when I am trying to visit this page https://rashadulalam.com/register/ after show this message: the page isn’t redirecting properly

Hi, On 06.23.24 I purchased an extension for Download helper to get rid of the QR-Code. Since the last update, it no longer recognizes this extension. Please help! My account: didier.soder@gmx.ch Regards Didier

I clicked on what may have been a malicious link last night. A Firefox message popped up immediately warning of viruses, so I exited out of Firefox and then ran a full McAfee scan -- which found no viruses.

But I am now getting popup messages, purportedly from Firefox, warning me that my McAfee payment has been rejected (not true) and warning that Windows Security has located viruses. A capture of one is attached.

Note it says it's from qltuh.check-tl-ver-106-1.com.

Assuming these aren't legit, how do I remove them?

Thanks!

Hi, I have applied the latest updates on my Zimbra server (Ubuntu 20.04) last week and since then the emails contents are not displayed anymore in the classic web client, they are displayed only in the modern web client, I will attach same email in both clients to compare. In using Google Chrome there is no such issue

Over the past week or so, Youtube videos take a while to start, and will at times just stop and buffer. I turned off uBlock Origin for Youtube, and I have Youtube Premium, but this issue is still happening. Ookla speed test is 569.32 Mbps download, and 23.50 Mbps upload. My Firefox is set to automatically update. Current version is 127.0.1
