I have Norton 360. I just reinstalled a brother printer and now I get the "Your browser is being managed by your organization". While I sync with my laptop, as others have said, I'm not an organization. There is an Enterprise policy .

Active Policy Name Policy Value ExtensionSettings {"firefoxhpsureclicksecurebrowsing@bromium.com":{"installation_mode":"blocked"},"firefoxhpwolfsecurityextension@bromium.com":{"install_url":"https://addons.bromium-online.com/wsx.xpi","installation_mode":"normal_installed"}}

I can't store or edit any bookmarks. How do I correct this? I need answers in very simple terms as I am very much a layman with computers. Thank You!

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

Hello, It used to work perfectly now Norton is blocking because at the bottom left of the page protect query.com pops up, don't know how to stop it, hope you can help, regards, Claudine

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 have used Thunderbird for decades with no problem. On a new Windows 11 machine, though, I am having a problem. I am running 128.4.2esr (64-bit) and just reinstalled it, but keeping the profile folder.

When I start Thunderbird, it should open to mail, specifically a unified inbox and various other mailboxes below. Instead, usually, it is blank. Other reopened tabs correctly display their title and content. See screenshot.

Thunderbird works correctly if I start it in troubleshooting mode, but at this point my few add-ons are disabled. (Quicktext, Compact Headers, dark theme.) See screenshot, lightly redacted.

With Thunderbird running, in its bad mode, selecting "mail" brings up the same blank page. Also, "calendar" shows a correct list of my calendars but will not display their content. However, "address book" works, showing my address book correctly.

If I am lucky or patient -- waiting for the mail tab to potentially come to life -- Thunderbird occasionally works and, if it does, stays fine for days, as long as I don't close it. What could be going on and what should I try doing?

Thanks for any and all help.

AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!

Can someone explain why the emails I write are still spell-checked, even though I have unchecked "Check spelling before sending message" and "Check spelling continuously" in "Settings" countless times? Even the Thunderbird add-on "Replywithheader" still checks spelling, even though I have unchecked "spell-check" there too. I don't want spell-checking, but I can't get away from it! It really bothers me.

Hello I have Firefox 144.0 (64-bit) installed. I added Video DownloadHelper to Firefox, but its icon doesn't appear in the Firefox toolbar. I've tried using Toolbar Customization, but the Video DownloadHelper icon doesn't appear there either, so I can't drag it to the toolbar. Can you help me put the Video DownloadHelper icon on the Firefox toolbar? Thank you

This afternoon, without any warning, all my mail in every folder could not be displayed. This is the second time this has happened in the last month and a half. I have two mail accounts - one that goes through Yahoo and the other Gmail. No mail is displayed in either account.

When I run Thunderbird in troubleshooting mode, the mail does display. I then disabled the few addons that I use but that didn't make any difference. When not in troubleshooting mode, no mail is displayed.

Of course, there's "troubleshooting information" but that's way too technical for me to get anything out of it.

I've been a Thunderbird user for over 20 years and I would like to keep using it but this performance is discouraging.

What do I need to do to get past this issue? I'm assuming I'll be able to read an email response by using troubleshooting mode.

Thanks.

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

Hello,

New subscriber here. I have been given the task to test the install and uninstall of the Purview Firefox browser extension using Intune. I created 2 groups in EntraID, one for each (install and uninstall).

I have no issues with the installation. Initially, I left the test device in the install group and then added it to the uninstall group to remove it. (this usually works with other apps, it worked this way with the Purview Chrome browsing extension as well other apps) but when I do this, nothing happens.

Next, I removed the device from the install group and added it to the uninstall group only. Once the configuration profile applies to the test device, it allows the user to remove it manually (before it did not) but the extension remains installed.

I have created a policy using the administrative template extension uninstall option as well as with the OMA-URI settings but the same happens. When i check the device configuration for the device in Intune, it says it succeeded but that is not the case. The OMA-URI setting I was not too sure about, but gave it a shot. I used the UUID value for the Purview Firefox extension

I am attaching some pictures and hope someone can tell me what I am doing wrong. I can add additional information, if needed. I have opened a ticket with Microsoft last week but have not called me yet. I ran into this forum today.

Thanks in advance

Open in Conversation no longer an option in Thunderbird 128.5.2esr. The shortcut, shift control O, does not work anymore either.

Is there an add-on that will restore this essential bit of functionality?

I have the last Firefox version and am trying to add extensions (e.g. video download helper). When I click on Add to Firefox, it works at loading the extension, but without any success. The blue dot in the gray square dances and dances and dances.... Thanks !!

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.

Hello! Yesterday (03/16/2025) I received a message that the ChatZilla add-on to Firefox will be disabled on the next restart of FireFox. The message indicates that the extension could not be "verified".

I am using a VERY old computer for ChatZilla only: Windows XP Firefox 48.0.2 ChatZilla 0.9.92

I don't care about the age and inability to update any of the software, but I need to continue to use ChatZilla on this platform.

I have used ChatZilla on this machine for a very long time and do need to continue. Is there any way that I can make this work without having ChatZilla automatically disabled at the next restart of Firefox?

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

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.
