Firefox Community Forum

Hello. I developed an addon to delete multiple reddit posts. It's built with the help of claude but regularly passes ReferenceError: browser is not defined

I'm adding the 3 files for the overview. Does firefox need some sort of API? https://storage.to/c/IXAJT4jqn

I have seen many topics about creating your own extension and uploading it to Mozilla for approval but not publishing it so that you can use it yourself only, but none of them tell you what to do after your extension has successfully passed review. I would like to install the extension that I created (and can see in the "My Add-ons" area of mozilla.org), but I have no idea how to do that. Do any of you have any experience with this? This extension was previously only for Chrome but I made some changes to make it Firefox compatible, and I don't want to publish it since it's technically someone else's work. Thanks.

The Roboform extension does not work :-( This has been going on for 2-3 months now.... It keeps telling me the extension is installed (which it is) but not enabled (which it IS) Thank you

Отправил новую версию своего расширения (Keycure) на проверку 28.04.2026, прошло уже 9 дней. При этом ранее в поддержке заявляли, что проверка длиться не более 5 дней. Просьба разъяснить ситуацию.

С уважением, разработчик Real1k.

FYI I was having issues signing onto my citizens online checking account and also signing onto my email account with comcast. After a while I disabled the NOSCRIPT extension which solved both issues. I believe this problem may have coincided with release 150.2

Using a Mac Monterey 12.7.6 and uptodate firefox.

Trying to use "tree style tabs". I'm trying to drag and drop a tab named "CHILD" to a tab named "PARENT". Instead of appearing in the tab PARENT the CHILD tab disappears and its content is added to the PARENT tab.

I would prefer the child tab to nest within the parent tab.

Thank you!

I want to know why DeTrumpify has been blocked. I use it to block Trump because he is toxic and I don't need that in my browser. So now the very tool I use to block all that hate has been blocked for being hateful? Mozilla, grow a back bone already! And leave my extensions alone! I'll decide what is hate on my device. I don't need a scared corporate nanny to do it for me. Pathetic. DO BETTER!

I am returning to Firefox after a long time. I've added the bonjour start page which is working fine with one exception. I am unsure if this problem is associated with the extension or with the Firefox browser, bonjour is working fine but I get a long message in the search bar telling me "bonjour Start page" (See included image). I'm trying to customise the toolbar does not allow me to remove anything relevant to that button or whatever it is. I can drag it off the toolbar but it just goes straight back on the toolbar by itself. The long and short of it is that it's taking up quite a large chunk of the toolbar and I don't want that I know that I'm using Bonjour I don't need to be told constantly.

Any help would be appreciated Thank you

When I put my PC to sleep, my add-ons disappear and stop showing up, and I get automatically logged out of sites I was logged into. After that, a message appeared saying that Tab Session Manager was corrupted. When I tried to repair it, all 200 or so tabs I had saved previously disappeared. How can I fix this? I’m really stuck.

I can no longer pin extensions/add-ons to the toolbar. My interface does not look like the one in the help section. I don't see a gear, I see three dots. And when I click on the three dots I don't have the option to pin to toolbar.

I am using Firefox 147.0.4 on Mac OS 26.3 Tahoe.

I've been extensively relying on the `Ctrl+Alt+X` shortcut to spin up the selected chatbot in the sidebar, but ever since I reset my pc (complete reset, cloud download of windows, clear all apps and files) and re-installed firefox, the keyboard shortcut isn't working for me anymore.

I installed firefox with chocolatey, upon noticing that the shortcut had stopped working, I tried to downgrade to v145, which didn't help either. So an uninstall and re-install later (this time manually downloading the installer exe), `Ctrl+Alt+X` still doesn't work. Although hovering over the chatbot's icon in the sidebar shows the shortcut in the tooltip.

More info: `choco uninstall firefox` created a backup of "Old Firefox Data" or something similar, could that have somehow persisted the malfunction across installs?

Any help would be appreciated! System: Windows 10 Pro Firefox: 146

I've been using MAC (multi-account containers) for a few months. Awesome feature, especially useful for logging into multiple email accounts in the same tenant (M365, GW, etc). In the recent past, if I had an issue with a particular login, I could go to the Firefox Multi-Account Containers extension button on the top bar, click on it...then Manage Containers, select the container to manage, there was a set of options, one of them being "Clear Cookies and Site Data" (or similarly worded). That would clear the data for that MAC which would resolve my issue. Now. that option is no longer shown when clicking the Manage Containers button. I've included a snapshot of what is shown now.

The ability to clear the data for that particular MAC is invaluable. How can I get that back?

MacOS (26.3.1 a). Firefox 150.0 (aarch64)

P.S. I just found the "Report" option on the extension itself in the Extension settings. I will post this message there as well.
