Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

The default font I have been using in replying to messages used to be in the same as what was designated in the Composition settings. Now, with the EnhancedReplyHeaders extension, the default font is always "Variable Width," no matter what I do with the Composition settings. What do I need to do, to have the default Reply font be the same as that specified in the Composition settings? Thanks,

Unfortunately the latest release has broken the ability to support the NordPass extension. I also have WaterFox as a backup based on historical usage challenges, and sure enough it supports NordPass with no issues.

The issue is when a user completes the Account login to Nord itself, then enters their master password for NordPass via the browser. It then gets lost, presenting the animated circle as if it is attempting to process the next step, and it fails to exit that state.

So I am running 31 add-ons. 30 of them ARE ACTIVE. (I've ALREADY ACTIVATED THEM.) Only 8 are showing up on the tool bar. I would like to select ONE that is not showing up for use. I have double, triple and quadruple checked, it is active...but it does not show up on that toolbar. I WOULD say that it is because there is not enough room, but there IS enough room for at least 3 others to be showing up. I can remember a day when there was 12 of them showing, and I had an arrow to select to see the "hidden" add-ons. That is not present. I cannot find a way to "show all"... unless it is just going to the install center to see that they are BOTH installed AND active. (Well, one is not active, but that is for a reason, and it's not the one that I want to use at this time.) While typing this, I tried something, I right clicked on the toolbar and selected customize, and I SEE the old familiar >> but it is grayed out. Once I click on "done" it disappears again. It is that ">>" that is missing. Yes, it's called "The overflow menu"... THAT is what is missing! How do I get that back?

Every now and then a folder flag will change to the drafts flag/icon, it seems to be a random occurrence which can happen to any sub-folder. Up until the most recent Thunderbird upgrade I had a working extension called FolderFlags which allowed me to go into the Folder properties and change it back but that extension no longer works with the latest version of Thunderbird and there is no alternative extension. How do I change the flag back to it showing as an ordinary sub-folder in my Inbox instead of Drafts? As an interim measure I've created a new sub-folder and copied the emails from the old into the new but that's not ideal at all. I hope somebody will create an updated extension but has anyone any other suggestions please?

I absolutely do not want "perplexity" anywhere near my Firefox IOS environment. I don't like it, and further dislike "perplexity" inserting itself to my browser experience. I consider "perplexity" a nuisense and an obstacle to my search habits. I have followed a removal process by logging into my "perplexity" account under Settings, and requesting Delete with no success, "perplexity" remains.

Please share with me how to rid "perplexity" my Firefox browser experience!

I have added the "Firefox Multi-Account Containers." I see the container icon, indicating it is "contained."

I have clicked manage containers and created separate containers like news for instance. I switch between personal, news, shopping and used each supposedly separate container.

But, I see the same history in each, which is not what I expected. Do I need a different Firefox account for each container?

Tried disinstalling and re-installing, but nothing. The add-on seems compatible with the versione of Thunderbird, the 141.0, but in reality doesn't work. Could anyone here give a help?

In Outlook it is possible to have the favorites fixed in top of the folder pane column. This is very handy when moving emails from the inbox to often used folders which fall outside the displayed part of the folder pane. (You don't have to scroll back if you want to display the content of the inbox). I cannot find a way how I could do this in Thunderbird. Is there a way to fix favorite folders in top of the folder pane?

This question was asked 10 years ago but I can't find where a fix was ever found for the latest version of TB. I would really like to keep the favorite folders in sight while scrolling down through the other folders I've created.

Is there an add-on for this? I searched without finding one.
