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.

Recently moved to Linux Mint with Thunderbird 140.5. It's a new experience. Thunderbird has downloaded all my emails and folders from my Outlook.com account. Can send, receive, edit emails no problems and all is visible from Outlook client on other machines. Thunderbird does not show my calendar entries or contacts. I do not wish to import from Outlook as I would like to access my Outlook.com from several locations. Been through online Help articles. Nothing seems to work. Have installed TbSync and Lightning Calendar Tabs add-ons with default settings. I have tried suggestions provided in this Mozilla Support. Other forum suggestions don't seem to relate to the version I have.

I'm sure it is something simple as everything else I have done with my new environment is working wonderfully. Thanks in advance.

Good day, The issues that I am encountering are explained below. The solution found after hours of research is uBlock Origin : https://ublockorigin.com/. Do you know which filters and rules should be applied to exclude the Wikimedia Foundation and all of its derivatives from the results provided by my search engine? Please share your knowledge. Sincerely. ________________________________________________________________________________________________________________________ I am utilizing Firefox ESR 128.10 desktop version on the Linux operating system. I wish to conduct research on the internet, utilizing the Startpage search engine. I would like to exclude the following sites from my search results: wikipedia.org, the Wikimedia Foundation, and any affiliated websites, regardless of the language or location settings configured.

What is the correct approach to establish a customized Startpage search profile excluding all Wikimedia Foundation sites? What is the proper setting to create a persistent and customized search engine configuration that excludes all Wikimedia Foundation domains even after an operating system update or reinstallation? Is it permitted to manually manage a customized search engine?

I have been advised to utilize an add-on or create a dedicated profile.

What would be the most suitable solution in my case, and the one that will be the most effective and stable ?

It is unfortunate that mozilla-firefox does not appear to offer a 'blacklist' or exclusion list feature, as that would be the most direct approach to excluding the Wikimedia Foundation websites from the search results.

I thank you kindly for all of your suggestions and responses to come. ______________________________________________________________________________________________________________________

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

I use Free Download Manager v3.97 along with FF Free Download Manager extension v3.22 to download files from Easynews.com. This issue may have nothing to do with Firefox except that the problem started a couple of days ago about the time 1.46.0 was installed.

When I right-click to download a video file, FDM is configure to automatically start the download. But downloads are not starting automatically now. FDM just shows the download with an hour glass figure. I have to manually stop then start the download.

Hi there, I'm experiencing an issue with the Microsoft Teams add-on in Thunderbird, specifically when using it with multiple Microsoft Exchange accounts.

Issue Description:

Previously, I was able to select between accounts using the Teams icon in the toolbar without any problems. However, after switching operating systems, the behavior has changed:

  • When I hover over the Teams icon in the toolbar, the account selection menu appears as expected.
  • As soon as I move the mouse to select an account from the menu, the menu disappears immediately before I can click anything.
  • I've made sure that the mouse doesn't leave the icon or jump erratically, but the menu still vanishes every time.

This only started happening after I changed my OS. On my previous setup, the add-on worked fine.

Fixes Attempted:

  • Removed and re-added the Exchange Accounts
  • Reinstalled the Owl for Exchange add-on
  • Fully uninstalled and reinstalled Thunderbird, including manually deleting the profile data folder
  • Disabled hardware acceleration

So far, nothing has resolved the issue, and I haven’t found any other reports of this specific behavior online.

The attached image shows the account selection menu when hovering over the teams add-on, but as soon as the mouse moves over to the menu it disappears.

System and Application Details:

  • Thunderbird Version: 139.0.1 (64-bit)
  • Operating System: Kubuntu 25.04
  • Desktop Environment: KDE Plasma 6.3.4
  • Display Manager: X11
  • Kernel Version: 6.14.0-15-generic (64-bit)

Any suggestions or workarounds would be greatly appreciated.

I have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated

Dear Sir,

Firefox is not working with Rabby Wallet and Metamask extensions.

It does no pop-up the window to see the transaction and sign it. Firefox 134.0.1 (64-bit). Windows 10 Home.

On Metamask at least I can click on the pinned extension and see the window. However it´s not the expected behavior, because it should open the pop-up automatically. With Rabby wallet it is impossible to proceed, even clicking on the extension icon.

Please fix it.

I want to avoid any 'ai assist' searches because I do not find their summaries accurate or valuable enough to be worth the environmental impact they consume. I know my web browser searches are not under the control of firefox, but for privacy and security I kill cookies when I end browsing sessions. So I am not staying logged in to search engines when I finish my sessions, and setting my preferences to 'no ai assist' on DDG doesn't last session to session because the search engine defaults to 'ai assist' searches now, as does google.

Are there any search engines that do not use ai?

Has anyone written an extension/add-on to FF that would add 'minus ai' to all my searches no matter what browser I use? Or otherwise indicate to search engines that I do not want ai-assisted summaries period?

We've got various privacy options built into FF--this is why it is my preference always--and it would be LOVELY to have a 'no ai' option too.

I have been using Easy Screenshot for years. Today I tried taking a screenshot and it opened a huge copy of the rectangular image I wanted to save in a new tab. Then there was no visible way to save the image. I used to get the option to save the image file in the same tab as the image I wanted to save. Took a screenshot and saved in Paint to show the contents of the Firefox window that image is huge and should have been 4 inches wide at most. Also the lack of how to save the image.

I'm wondering if this a because of the latest update. Firefox 147.0.1 X64 desktop WIN10 22h2 with ESU

When I tried reporting the problem on the add-on page the website it tried to connect to was not working so asking here for help.
