Hi. When 7TV Exstension https://7tv.app/ come again on https://addons.mozilla.org? It can’t be installed even manually, because Mozilla complains about the digital signature of the extension. How can this be bypassed or is it only possible to “temporarily” run the extension through debugging?
I also saw how the 7TV extension was always removed when someone tried to add it to the extensions site.
Are you using up-to-date Firefox? (Firefox ESR 128 or above)
Because I’ve tried to install it using the provided file and it works OK.
Yes, i have latest verson Mozilla - ESR 140.0.2 - 64x. Not allows to install 7TV manually - temporarily allows
7TV GitHub is silent for now - apparently they are in no hurry to solve the problem. That’s why I am writing here - maybe there is a way to bypass the digital signature. Or I will have to install a special version of Mozilla for developers…
P.S. xpinstall.signatures.required: false is not help
There must be some reason why Mozilla doesn’t allow it into addons.
@Synth_Kot, the Firefox version number you shared doesn’t make sense to me. Could you open a tab to about:support and share the “Version” and “Build ID” values you see there?
I just tested this locally using Firefox ESR version 140.0esr and Firefox version 140.0.2 on macOS 15.5. I was able to install the 7TV version 3.0.9 (current stable release) without issue. My best guess is that the version of the add-on’s XPI file that you’ve downloaded is corrupt.
I’m not sure what’s gone wrong, here are two quick ideas on things you could try:
curl or another browser to re-download the XPI file, then drag it onto the about:addons page in Firefox.Version: 140.0.2
Build ID: 20250627085530
Windows 11 x-64bit
Ok, i try it
P.S. I tried to install Latest Nigthly Version 7TV 3.1.8.1000 - 3.0.8\3.0.9 is works, but i want to install XPI-file latest version 7TV (3.1.8 - pre-release or 3.1.6 - stable): Releases · SevenTV/Extension · GitHub
It’s not working. Also not allows to install manually
It’s not working - I created a new Mozilla Account. It still won’t let me install the extension manually, because it complains that it can’t check it - apparently for a digital signature. The extension was downloaded manually from Microsoft Edge - I don’t think it’s damaged. It does let me install it temporarily, which is interesting. Here:

EDIT by @dotproto: Removed the 3.1.8 and 3.1.6 XPI files uploaded here. They can be downloaded from the GitHub project’s Releases page.
Thanks for sharing that link. I’ve verified that the 3.1.X versions do not load in Firefox. I looked around the project’s repo and according to this comment on issue 1117, it seems that the extension has been rejected by Mozilla due to remote code execution. Unfortunately, this means that signed versions won’t be available until the developer fixes this policy violation.
It’s a shame that Mozilla can’t do anything about it. Well, let’s wait for the guys from 7TV to fix the situation. But I don’t think it will be fast. I wrote to them first, but they are silent.
In general, I just additionally downloaded the latest Nightly Version of Firefox and disabled signature verification there. The latest pre-release version of 7TV was able to install without problems. I will use it like this for now.
