I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

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.

Topic is Extensions. How do we get an extension to be recommended by Mozilla? Maybe we can upvote to do this.

"Gmail Conversation Reversal" - likely the first one with the most reviews and most recently updated. SS attached.

Thanx

Very recently upgraded Firefox for Android from 147.0.4 to 148.0.1; I knew a bit about upcoming changes of menu system (but we also got fancy rounded corners ...).

But this is in part utter rubbish.

I know it has been possible to move the address field from top to bottom, and that that might work better with the new menu, but even if closer to fingers holding the phone it will anyhow be so low and in a corner that you can't reach it without risk dropping the mobile. And this, the new menu, isn't even my main issue. With the menu at the top, and the old menu system, you at least continued to work in the same area, once you had opened the menu.

The amount of "clicks" is pretty much the same, though; 2 for bookmarks (if you don't simply type part of the address), pretty much the same for add-ons (several use white-listing for scripts, such as NoScript, and often have to adjust these, so those settings are quite frequently used).

But, the main issue is something related to "gestures", swiping down a web page seems to invoke some add-on setting, in my case NoScript. That is, strict vertical swipes works most of the time as before (and "most of" is pretty much a disaster), if I swipe slightly diagonal (exaggerated in image), I get an icon for NoScript (scripts not enabled for page in example), and the further I swipe the bigger the icon. It goes away if I lift finger, but if I move into the icon, it can invoke NoScript's settings.

Is this the intended behaviour? And above all, scrolling down should work 100 % of the time.

Hi everyone,

I recently built a small Firefox extension for my website https://calcolo-stpendionetto.it https://calcolo-stpendionetto.it , which helps users calculate their net salary in Italy using updated IRPEF and INPS rates.

However, when I try to upload the extension to addons.mozilla.org addons.mozilla.org (AMO), I keep getting this error message: Signing is not possible due to an error with the manifest file

{

 "manifest_version": 2,
 "name": "Calcolo Stipendio Netto",
 "version": "1.0",
 "description": "Calculate your Italian net salary (IRPEF, INPS, regional tax) quickly.",
 "icons": {
   "48": "icons/icon48.png",
   "128": "icons/icon128.png"
 },
 "browser_action": {
   "default_popup": "popup.html"
 },
 "permissions": ["activeTab"]

} I also tried switching to manifest_version 3, but then Firefox gave a warning that some properties like browser_action are deprecated or not recognized.

Has anyone experienced the same issue when uploading finance or calculator-related extensions? Is there a new manifest format or signing rule I might be missing for Firefox extensions?

Any help or examples from working extensions would be greatly appreciated. Marien Klin

Since to old add-on enabling customization of the message header toolbar doesn't work now, where might get one the is compatible with Thunderbird?

Thanks, James

Is anyone monitoring this community? Has it been abandoned?

I've been having an ongoing problem. I fixed it myself, because after posting here, I had zero responses and didn't know what to do, so I messed around and tried things on my own, which seemed to fix it. But apparently, it is not fixed, and I still don't know what to do. A Firefox expert I am not.

Very simply, I use two different computers, each 2000+ miles apart. Each time, and this has worked for well over 3 years now, the entire computer is copied to a backup. The backup data is restored, the current Firefox profile, as well as the Firefox program. To repeat, this has worked for well over 3 years now.

In order to get the extensions working, that requires disabling and then reenabling each one. (Otherwise, Firefox will not access the internet.)

This time, the extensions were disabled and enabled, and everything appeared to be working fine, but nope, not a single extension works. Even choosing a different extension that is normally disabled doesn't work.

I used to use Adaware, which is on the disabled list, so I disabled the non-working Ublock Origin and enabled Adaware, and it doesn't do anything. The ads roam freely all over the page. They pop up and dance around.

Not one extension will work. New, old, enabled, disabled, whatever. Nothing.

Does it bear repeating that I am not a Firefox expert? Without an answer from someone who knows what they're doing, I may as well switch to crap, inferior Edge with the zillions of dancing, pop-up ads. And I hate Edge.

I'm begging for an expert to help here.

Shortly after upgrading FireFox, whenever I try to go to a website, like PayPal or my bank or anything else, I immediately get a large Ad/site for something frequently related somehow.

Like my bank I will get something suggesting an online bank, or ways to make banking easier. It will be a large window, covering my original window. I have to exit THAT site to get to the one I want.

It is a separate window, I cannot just X it out, I must shut down that window. Then the window that I actually want will be beneath it.

I can't figure out how to fix it.

Hi,

I am trying to make the jump away from Chrome to Firefox across all the platforms I use. I am a long term user of NordPass for password management and I love the Firefox/Nordpass extension in Windows 11. Firefox for Android, while not as slick as Edge or Chrome on this platform, I have been recently using it as my default browser. However, I could not find the Nordpass extension for Firfox Android.

A quick search took me here: Cannot find Nordpass to download as addon it was asked 3 years ago with "This add-on is currently unavailable in Firefox for Android but may be included in a future update."

Are there plans yet to implement a NordPass extension for the Android platform?

Thanks

the last update disabled my group speed dial that had hundreds of saved research bookmarks. How do I go back to the previous version and restore my group speed dial bookmarks? The update should have warned that this extension would be disabled. This is a disaster!

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

During recent update 148.0 (64-bit) google calendars are not shown either in "Events and Tasks/Calendar" or in "Today's Pane".

Subscribed calendars are still there, but nothing is shown in the days/weeks/months entries apart from the first calendar in the subscription list! Nothing else. And nothing in today's pane.

Reinstalled Thunderbird and reinstalled "Provider for google calendar" but nothing changed.

Thanks, GG

I'm away at another location for a few months out of the year. The computer in the other location is almost identical to this one, done in a very simple manner, by using a backup and then reinstalling everything from previous computer to current, most of which is data.

The Firefox profile is copied over and then the version of the program from that other computer is copied, so the profile and program match. The last step is to disable each add-on individually, then to immediately enable them again. (Otherwise, the browser won't connect to the internet.)

I followed the same procedure today as every single time. But then I noticed the blank new tab add-on isn't working. And upon looking at the add-ons...none of the enabled ones are listed (or working). Only the disabled and recommended ones. I don't even know which were installed, and would have a hell of a time figuring out which ones are supposed to be there, and how they're set up.

Where did they go, and how can they be reinstated?

This has never happened before, and I've been doing this same thing for at least 3 years.

Thanks in advance.

I seem to have purchased "Owl for Thunderbird," unwittingly paying 10 Euros ($11.93) while in England on 2.11.26. I don't want or need it and I want remove and cancel the add on. I also want to stop paying. How do I do that? Where is it hidden in Thunderbird?

I know that there is already default containers built-in without the need of the extension. But there's no way to open tabs in containers when we click a link, only when it's typed in. There's an option in settings that allow to pick a container when a new tab is opened, but that's it. It would also be great to move the Mozilla VPN and integration and sync function from the extension to the settings page for easier access.
