Firefox Support Forum

Firefox updated yesterday to ver 90.0.1 (64-bit). Today when I open Firefox browser, Malwarebytes blocks an exploit with thiis message: Malwarebytes www.malwarebytes.com

When I open in safe mode, no problem. I can not find the extension causing the problem

Using Firefox, I am unable to share articles from The New Yorker's website to Facebook on my IMac. I get an error message that reads: "App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin. for permissions." I do not get this error message when I use Safari, only Firefox. There is no administrator as this is a home device, so what do I have to do on my Firefox settings to access permission?

Hello.

90.0.2 (64-bit) on Ubuntu 20.04.

I noticed a lot of activity from my desktop computer to various ip's at bc.googleusercontent.com whenever I start, visit sites, or shut down firefox. I know this because I'm watching the tcp stream with tcpdump | grep 'googleusercontent'

This ONLY happens in Firefox not chrome or other browsers. Seeing this is a fresh install with no addons, tweaks, etc. I'd like to know WHY a fresh install of Firefox phones home to some googleusercontent user. See below snippet of logs:

Hello, there still is a Firefox Sync account for the email address fraavunbensem@hotmail.de. This is the email address of my late mother. I closed the email account years ago, but now I cannot even close the corresponding Firefox Sync account. Thanks y'all for your help!! Karl

Hello all,

Lately I received a report from some colleagues that a certain feature is not working in Firefox that appears to be working on any other browser.

When drag/dropping e-mails and/or attachments from Microsoft Outlook (Microsoft 365 Apps for enterprise) to a drop-field in Firefox (88.0.1 - 64-bit) nothing happens.

When using Firefox we can drag/drop files from Windows Explorer, but not from Outlook.

The same fields do work flawlessly when drag/dropping e-mails and/or attachments from Microsoft Outlook in Google Chrome, Microsoft EDGE, Opera and Safari. So Firefox is the only browser - on several OS's - that does not allow e-mails/attachments to be dropped from Microsoft Outlook. We have tested multiple users on different workstation and we have tested drop-fields from several web applications.

Surprisingly I cannot find any solution to this. The only similar cases I was able to find are from a couple of years ago but are about the other way around (so drag/dropping files FROM Firefox to another application).

At this moment I am advising my colleagues to use another browser. But we really want this to work properly with any browser of choice. Hope this community can help us out.

The update to Firefox 89.0 did not fix this problem.

Note: UAC is enabled on the workstations. Disabling does not affect anything. Tested attachments: .pdf, .docx, .html & .xlsx

Hello Mozilla Team,

I have a small problem.

My home server was killed by a flood, so I lost my password manager (2FA & recovery code). The geo backup was unfortunately a bit older and does not contain the data for my Mozilla account. This has now locked me out of my account, but I still want to delete it. I have read the article (https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication), but I still have the right to delete my account and have my data deleted.

I would like to know who to email to get this started, Stay healthy, thanks for the help.

Hello,

Thunderbird got updated to 78.12.0 by Mozilla Maintenance Service this morning and I believe Firefox got uninstalled by accident during the process.

The reason I think it got deleted by MMS is because in `C:\Program Files\Mozilla Firefox` I could see a single file named `tobedeleted` and when I read the log located at `C:\Program Files (x86)\Mozilla Maintenance Service\UpdateLogs`, the last two lines were : NS_main: unable to remove directory: tobedeleted, err: 41 NS_main: directory will be removed on OS reboot: tobedeleted

Luckily my `%APPDATA%\Mozilla\Firefox\Profiles` were not affected by this issue and I managed to recover my data by reinstalling Firefox.

Best regards,

Tolga Taluy
