Not sure if this question should be directed to the Mozilla dev team or 1Password dev team. Who is in charge of implementing the integration of the 1Password extension? It currently doesn't provide same functionality as when implemented in most other common browsers (Chrome, Safari).

Until some days ago I could use the add on "Video Downloadhelper" without problems on my old Macbook Air (2017) with OS10.15.7 but suddenly the add on was not available anymore. I purchased a valid license for this add on. In the Firefox adjustments it was mentioned as deactivated. Could you please let me know, how I can activate the Video Downloadhelper again? Thanking you in advance for your kind support. Sincerely, Ulf Gaertner

After my browser updated to the latest version of firefox I now get a white banner bar at the top of my browser that literally obscures everything at the top of any website I browse. you can scroll up and down in the white banner and apparently its an error message for the extensions not connecting. I only have adblocker extension and it was installed from the extensions provided in the mozilla store. How do I get rid of this as it makes most sites I visit unusable as you can't use any menu from that site. it seems like maybe its not connecting to the adblocker server and they'll probably update eventually but until that time I cant even sign in to google because its covered by a banner that would tell me that it cant connect to adblocker.pcvark.com? I've been a user since like 2005/6 and have never had any type of problems whatsoever so whatever help you can provide is appreciated.

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.

I installed the English (US) dictionary add-ons from Mozilla Add-ons (English-US Dictionary and US English Dictionary). Firefox confirms they are installed and shows a “Remove” option, but they do not appear in about:addons under Dictionaries or Extensions. Additionally, the dictionary features are not working on webpages—there is no “define” option on text selection, and no dictionary/lookup functionality appears even after double-clicking words or using context menu options. The add-ons only appear as installed on their web pages.

Expected behavior: Installed dictionaries should be visible in about:addons and provide word lookup/definition functionality in the browser. Actual behavior: Add-ons are not listed in about:addons and provide no visible or usable dictionary features on webpages.

There is much more to the following that I received from ChatGPT: The first place to seek answers is obviously with VeePN. I asked ChatGPT the following questions, and as a result, I also have some questions for Firefox. Where can I get answers? I do not like the Edge browser for several reasons. Firefox, as far as I am concerned, is the best browser for my use. Due to the fact I reside in Kaliningrad I must use a VPN to access sites I used to take for granted when I lived in the Czech Republic. This morning, as usual, I tried getting connected to VeePN in my Firefox browser. As usual, it does one of the following: 1) “Something went wrong at our end.” & “try to update” or “contact us for assistance.” 2) Continuously refuses to connect, leaving with the message: “Connection Error. Can’t fetch server config.” 3) Connects very soon after opening Firefox, perhaps 5% of the time I try connecting to VeePN. This morning, I spent many attempts over the course of 2+ hours, and no connection. Sometimes I had to refresh the VeePN extension due to the immediate, continuous, fast popups of “Connection Error. Can’t fetch server config.” Then suddenly, without rhyme or reason, VeePN connected. Also, this morning I decided to test using VeePN on my Edge browser, and it immediately connected, with no hesitation. This begs the question. Is there something about Firefox that may be causing the issue? I have not changed any settings anywhere regarding WiFi or Network & Internet Settings. In addition, sometimes, when I tire of trying to get VeePN to connect in Firefox after decades of connection attempts, I will use my Browsec VPN. I have learned not to use two VPNs simultaneously, one or the other, not both. Also, it is worth mentioning that VeePN is far superior to Browsec, but that is my opinion based on how they both perform after being connected for a good period of time. I can be connected via VeePN all day and have no issues. Browsec requires regular refreshing. Either VPN, however, is affected by the internet connection and the wireless connection between my router and the dongle that sits on my desktop near my PC. Yes — based on what you described, this strongly suggests the problem is more related to Firefox itself (or the Firefox extension environment) than to your internet connection or VeePN service overall. I have added an image of all the Firefox Extensions I use, obviously, some in the list are turned off. I would like to add the information that ChatGPT provided, it is in a Word doc that can be uploaded to help if needed.

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.

I want to be able to select the ai program I would like to use when researching (anything), like I have with Claude, but I don't know how to download the programs and have on the side bar like I have claude. Please help. Also, I can't download Deepseek.

When tab session manager (TSM) saves multiple windows, each with dozens of tabs, into a single imaging session file, TSM also creates and displays a list of those saved sessions. TSM now does not open any of multiple saved windows when any one of the backup listings is selected.. At one time, it did. Instead, TSM opens a single window and its tabs, on request, but opens it into the current window, only, When a new window is msnually created into which to drop the tabs, TSM simply refuses the new window, and replaces verything with a new window for its own tab collection..

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?
