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.

I have been using uBlock Origin for years to block ads in youtube. Recently I started getting ads again and when I checked I found uBlock was disable snd couldn't be enabled. I dl the latest version but it gives me an error message when I try to load it. Please help.

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. ______________________________________________________________________________________________________________________

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.

Why have ratings of reviews on Amazon disappeared and how do I restore that feature? I do not see a price tag in the upper righthand corner. I'm running Firefox on a PC w/Windows 10.

I have just got a new laptop and installed everything in relation to Firefox onto it. I have used the Nordpass extension for a couple of years and on the old laptop this is version 5.23.13 updated 16/10/24. On visiting the add-on and extension site today there is only a legacy version 4.33 updated 2y ago which clearly no longer works. Where has it gone. Clearly I am going to ask the same question of Nord, but I hope you can help.

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.

Recently I've had the Un-welcome experience of Scripts triggered on YouTube, which Over-ride my Installed extensions to Firefox.

I've had YouTube, somehow Disable extensions and refresh the webpage... Without my concent or even an option for concent!

I've even blocked the popup window, which triggers the script which performs this action within another extension... and within 7-10 days Youtube has by passed the bypass that i've employed...

In my opinion a web-browser which allowes for extensions to be installed and run... should Block any and All scripts which try to disable extensions!

I seriously hope this can be looked into asap... or someone in the community has a work around, as my work around (blocking hte window which triggres the script, which disables the extension....) was by-passed within 7-10 days...

I used to think myself a compettent net user, but i'm aged out atm... still if i'm unable to prevent this sh*t and manipulation within FireFox, I doubt the average user or the layman will have a chance in hell of being secure and keeping their chosen extensions running...

This needs looking into ASAP!

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 have the below problem with Firefox 141.0!

Ad blocking on the website => https://satkurier.pl/ - how to disable it?

A message appears in Polish: Please disable ad blocking and refresh the page.

Thank you for help in advance,

Maciek

currently using FF; I do NOT have any ad blocking software installed ( that I know of) I searched my computer for the word block, and it did not show it anywhere. I also have Mozilla Seamonkey installed, but not using it. Each time I visit a news website I get a popup that claims Im using an ad blocker. I have searched all those adbocker pgms on my computer and none exist. Why am I getting these pop ups. I think I also checked the AVG pgm, but didnt see an adblocker there. How do I fix this situation from continuing

I just started getting an annoying ding/small pop-up window that appears to be a link to various ads . . . I would like to get rid of it.

I assume it is FIrefox, as it started happening after my most recent update. I also assume there is a setting I can use, but I don't see a settings icon in Firefox. <Sigh>

Possibly it only pops up when I'm using Duck Duck Go, but I'm not sure about that.

Sure need some help here . . . much appreciated.

Firefox says versions earlier than 115.13 will be impacted by the certificate expiration. I've updated to 115.21 My add-ons are still disabled. https://support.mozilla.org/en-US/kb/root-certificate-expiration

It seems many don't know or haven't noticed but merely running an esr branch (rather than a developer edition) will also give you the option to enable add-ons with expired certifications via about:config.

Anyway, the "legit" way isn't working.
