Hello, I am facing an issue while playing YouTube videos in Mozilla Firefox. The videos are very choppy and do not play smoothly, even though my internet connection is stable.

Here are my details:

Firefox version: (please add your version)

Operating System: (Windows / macOS / Linux / Android – mention yours)

Internet Speed: (optional, if you know)

I have already tried basic steps like clearing cache and restarting the browser, but the issue still remains. Could you please guide me on how to fix this?

Thank you for your help

Will the important announcement of the closure of Beijing Firefox and the termination of Firefox account services lead to the use of the clipping plugin that I previously installed in the Firefox browser

what should I do if I want to continue use clippings in my daily job

Hello, Some 12-14 years ago my US based website manager signed me up with Thunderbird since he was having issues getting my Outlook to be compatible with his server. It had been relatively trouble free until recently.

When a recent update occured it appeared that Thunderbird had vaporized my e-mails from 2023/24. I had/have numerous e-mails related to a lawsuit that is tremendously important to me. I read on Mozilla's site about a program alled Recoverit from Wondershare. It did not appear to work at all. Not too long after my Lenovo PC died. The techa at Memory Express could only see a single program on my hard drive when I took the hard drive to them for analysis. I subsequently sent the drive to Secure Data

and they are sending it back to me.

In the meantime my replacement computer is an HP laptop. I purchased Windows 365 since they provided a technician to assist with setup. The tech could not get Thunderbird to work nor could they make Outlook work, MS blamed the server. The server guy says ir works, I have been without my e-mail for more than 6 weeks.

Can anyone help?

I would like to centrally distribute and manage Thunderbird 140 (ESR). We have decided to configure it via policies.json, as we want to manage Windows endpoints as well as Macs.

In a later stage, the installation script will be distributed via Intune.

I am currently testing the script on my Mac with macOS 15.6.1. The script performs the following steps:

I am able to create policies.json and the distribution folder, but Thunderbird can no longer be started because the app is corrupted.

After some research, it appears that Gatekeeper from MacOS is probably responsible for this. When the policies.json file is saved, the code signature is no longer valid after startup. As a result, Gatekeeper no longer allows Thunderbird to run.

Does anyone have any ideas on what I could do to prevent this problem from occurring?

I use the Plusnet webmail server and find that every so often have to manually empty the Plusnet inbox. I do not want to automatically deleting them from my computer. I have set up my Thunderbird account using pop3 and have tried all the combinations of settings in the heading...server settings..and checking and unchecking...... Leave messages on server For at most Until I delete them

and can not get the account to delete any emails from the server. Do I need to set something else under disk space? When you set For at most 14 days, is that 14 days from the email arriving at the computer, or 14 days from setting it to 14 days? Is there something that a am failing to do ? Any help gratefully received.

Hello, I can't send files, photos to social networks, earlier, when using another browser, I simply dragged files from the desktop or inserted screenshots via ctrl c, now I can't, they either don't attach or open in a separate tab. Please help, what to do about this.

If I click on the link, it tells me to login, even though I'm already logged in. It then says my username is already taken! And there is no option to go any further

I’m trying to add accounts to my company email. After entering the address and account name, the program keeps searching but cannot find the configuration. It keeps searching for hours with no result. Other addresses can be added without any problem, but the issue occurs with the domain pm-instal.com.

Hello:

I am trying to create a csv file of my passwords to import to Microsoft Edge from FF. I went through these steps in Firefox:

Settings>General>Import>Select Passwords from CSV...

...and then it takes me to browse my computer for a CSV file that I have YET to create. I don't think this is how you create such a file.

I'm not sure how to import my passwords to create a CSV file so I can put them into MS Edge. When I tried importing my password (and all my other data) inside of Edge via Edge, it only brought in 235 passwords from Firefox where I have 422. So I would assume if I used and imported my passwords to Edge via a CSV file instead that all my passwords would populate in Edge not roughly half of them.

Could you please tell me how to create a password CSV file in Firefox to use in Edge?

Many thanks in adabce

Dear Sir or Madam,

We are experiencing an issue with various users on our terminal servers whereby websites open very slowly when using Firefox. When I access the website using Edge from the same user session, everything works very quickly. We have already tried creating a new profile in Firefox and clearing the cache, but without success. Could you please help us?

The operating system used is Windows Server 2022.

I had addons, like Auto Profile Picture, working in TB with my POP3 account setup. I followed the TB instructions to set up an IMAP account for the same email address, with intention of that becoming my primary usage.

However, the addons are not working for the newly setup IMAP account. Is there something that needs to be done specifically for an IMAP or other setting that I am missing?

Hi I'm trying to contact thunderbird support because I cannot receive or send emails and my provider Free Parking has done all the checks and it is not at their end. Help please.

9/10/2025 After trying to send an email I got the following message. Repeatedly. Called Sitestar's tech support and they tried to fix the issue. Here is the first error message.

Sending of the message failed.

An error occurred while sending mail: Unable to establish a secure link with Outgoing server (SMTP) mail.sitestar.net using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.

Sitestar Tech support had me go to account settings, to outgoing server to edit and change the STARTTLS to SSL/TS port and retry sending the test email. Then got this error message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: H:RB [172.56.209.199] Connection refused due to abuse. Please contact your E-mail provider.. Please verify that your email address is correct in your account settings and try again.

Went back to set up and original error message still shows up and email can not be sent. Any ideas how to fix this. I can still send email thru the sitestar website, but not from my laptop. I think I used up all the Site star tech supports brain cells. I use the latest thunderbird. We connect to the internet via a T-mobile tower thing. Windows 11 Thank you

I'm making the switch from Chrome and trying to set Firefox up with a few settings that that browser has that I'm more partial to. The title might not have been clear - I want to make it so that when I open a photo or video in Firefox, the tab instantly switches to that new media. But, I want to keep it so that links that I open in Firefox in new tabs do not instantly get switched to. I see there's a option in the settings, "When you open a link, image or media in a new tab, switch to it immediately" - basically, I want the "switch to it immediately" functionality for images and media that I drag from my desktop into Firefox, but not for links that I open while using the browser, similar to how Chrome handles it. Is there any way that I can replicate this behavior in Firefox? Thank you.

I just upgraded to latest Firefox and all my bookmarks from the previous version are now all missing. Anything that can be done to get them from my previous version
