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.

Since Firefox updated to version 148.0 it has broken my ability to download any extension and I get that Installation aborted message for any extension I try to download.

It also broke my ad blocker, ublock origin, when it updated to 148.0

The new version of Download helper is uncommissioned for YouTube. I have tried everything including reinstalling, clearing cookies and catch etc. How can I just revert back to prior version as this seems to be a degraded version?

I have an "Ad Blocker" problem for years. I read the instructions "Adblck Plus Instructions" I cannot find "Beneath “Block ads on”, click the large blue toggle next to “This website”, no matter what I do. What am I doing wrong?

I need to install the Foxyproxy and the Wappalyzer, I do trust them but i don't understand why is Firefox disabling them while I have been using them for a while now WITHOUT ANY PROBLEM...

You don't even give a clear solution to why and how I can resolve this case on time so i can keep using the browser....issues like these make us users switch to more reliable,easy,supportive and less complex browsers.

[Coupongogo: Automatic Coupons & Cashback](https://addons.mozilla.org/en-US/firefox/addon/coupongogo-automatic-coupons/) is a malicious extension programed with a command and control server located in China.

Despite [Firefox user reports](https://www.reddit.com/r/firefox/comments/1pl0u6m/malicious_addon_does_not_get_taken_down/), the extension remains available on the Mozilla addon store.

A [rastersec.com contributor explains](https://www.rastersec.com/blog/coupongogo-cryptostealer),

>\[Coupongogo\] operates as a remote-controlled time bomb, utilizing a dynamic configuration system to evade detection, hijack all search and browsing traffic, and wait for a server command to activate its dormant theft capabilities targeting major cryptocurrency exchanges.

Given the lack of success at securing the privacy and security of users by using the standard addon reporting tool, how can I escalate this matter to a responsible Mozilla party for triage?

I've used Roboform addon before. Recently i had to reinstall win 11, and therefore reinstall Firefox, plus Roboform addon. Mozilla shows addon has installed, but it is not operating like i am used to. it will not auto load username/password automatically. I've checked several times, reloaded, and still can't find why it is not working. this includes going to Add-ons manager page in Mozilla, where it says Roboform password manager enabled. doesnt seem to be working to me. see attached screen shot any suggestions most welcome.

After updating firefox (to version 113.0.2 (64-bit)), I discovered that the add-on "Privacy Badger" I was using was off. I tried to get anew the add-on but received the above message.

Any help would be very welcome.

Hi there, I'm trying to upload a new version of my browser extension (version 1.4.5), but the submission is being blocked due to a version number conflict. The issue is that I accidentally submitted a different extension under this listing with version 1.7.7. I reverted it immediately, but now I'm unable to upload the correct version (1.4.5) because it's considered a downgrade.

I really don't want to change my extension’s versioning just to get around this, since 1.4.5 is the actual next version in my release cycle. At the same time, I don’t want to stop updating the extension on the Mozilla Add-ons store. Is there a way to resolve this?

this page "247sports2.com" keeps popping up when I log in to my account on "247sport.com! and I cannot get past it. Is there anything I can do?

I've appreciated using Firefox as my laptop browser for several years. However, now I've been getting full page pop-up advertisements that are beyond annoying since they appear in the middle of my logging on to sites. It is very worrying to see another screen pop up in between my entering a user name and a password. I have to wonder who is seeing my personal information? How do I stop these pop-ups besides choosing another browser? Thanks. Andrew Zacharias
