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.

I can no longer pin extensions/add-ons to the toolbar. My interface does not look like the one in the help section. I don't see a gear, I see three dots. And when I click on the three dots I don't have the option to pin to toolbar.

I am using Firefox 147.0.4 on Mac OS 26.3 Tahoe.

Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh? The original versions were perfect. The VDH version 10 vdh is straight junk!

I am 82 years of age and did not grow up with the Internet. I have a total of only 8 hours of training on a PC. I have no idea how my PC got into 'safe mode' and now all of my extensions are disabled. I do not know how to exit 'safe mode' to allow the extensions to be enabled again. I tried following the instructions as provided, but to no avail.

I tried to add extensions on my Firefox but every time I click, it said to download Firefox. I also tried the delete and download back method and that’s doesn’t work either. Please help

All I am trying to do is change the subject line on emails. I found the add ons Header tools lite and improved and installed them. When I select a email to edit the subject line I highlight the message go to menu message>header tools lite>edit lite or edit full source neither one does anything???

Also tried opening the email go to menu message>header tools lite>change header details hit enter nothing happens. Please help and thanks in advance

HI, After upgrade to Seqouia 15.6.1 an extension for developing Oracle APEX applications breaks Firefox. It is the only extension I have installed. Console information is not really that helpful. Maybe you can make some head and tails about it.

I did a new Windows 10 install yesterday. I then added my favourite apps.

When I got Firefox installed, adjusted the settings and added my extensions (most of which I've used for years), I found a glitch.

The icons for AdBlocker Ultimate and LastPass do not show up in the Customize Toolbar menu. I keep both of these on my toolbar in the past.

I've tried restarting Firefox several times and, finally, tried running it in Troubleshoot Mode. The last, it seems, doesn't allow the use of extension.

So ... please help!

How can I stop advertisers from changing my 'Settings' fields 'Home page and new windows' to their URL which brings up their page before I can enter my password? I'm on Linux Desk Top.

I am returning to Firefox after a long time. I've added the bonjour start page which is working fine with one exception. I am unsure if this problem is associated with the extension or with the Firefox browser, bonjour is working fine but I get a long message in the search bar telling me "bonjour Start page" (See included image). I'm trying to customise the toolbar does not allow me to remove anything relevant to that button or whatever it is. I can drag it off the toolbar but it just goes straight back on the toolbar by itself. The long and short of it is that it's taking up quite a large chunk of the toolbar and I don't want that I know that I'm using Bonjour I don't need to be told constantly.

Any help would be appreciated Thank you

TOPIC 1 In Betterbird there is the option to colour the email account. The only option in TB is to change the colour of the email envelope icon. There used to be a extension that achieved this but fell by the wayside in TB 115 I researched this on TB forum on reddit.... https://www.reddit.com/r/Thunderbird/comments/17unvb1/different_account_colors_in_thunderbird_115/

It made interesting reading and I did download the 'account colours' zip to install and see if it worked. Only thing is that I do not know how to install it........can someone brighter than me tell me how to install it and to remove it if it doesn't work. Many thanks.

I used Pocket for a while. It was excellent since it allowed taking a webpage and converting it to a document that could be copied and pasted to Microsoft word. This allowed further analysis and work on the contents of the page and was extremely useful.

Now that Pocket is gone is there another extension or a purchased extension that does the same thing on the present day Firefox.

I presently use Windows 7 and Windows 10.

Appreciate any suggestions.

On new computer. I went to Add-ons and searched for Imogies/Emojies, etc., but nothing comes up. I hoped to have the set I had as an add-on on previous computer (which crashed - had to start from scratch).

If anyone knows how to get it, I'd appreciate knowing. I loved using it.

(I know about "Win." - but that doesn't have nearly as many emogies as the Add-on.)

I checked my add-ons in settings to see what was wrong as I noticed the icons were missing. Upon looking at the proper tab, everything "could not be verified" (including themes) even though everything was working perfectly within 24 hours prior to the issue arising. When trying to reinstall anything from the extension store, all I receive is a "this appears to be corrupt and thus will not install." Clicking the "more information" button on any/all affected add-ons reveals that everything is unsigned. How do I alleviate this?
