Extension appears to be corrupt
Hi,
There many extensions such as:
https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:
Installation aborted because the add-on appears to be corrupt.
I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.
This addon, after download, installs fine as a temporary addon.
How can I install it permanently?
Thanks.

That's strange. They've been changing signatures recently (for extensions uploaded prior to April 2019; that one is newer), but it should be backward compatible. Wait to the next Beta, we'll see.

Edit:
1 - Trying in safe mode does not help. 2 - Disabling anti-virus does not help. 3 - Trying on Firefox standard works!

Will the beta show in the About dialog? If not, is this the one you mean:
https://download.mozilla.org/?product=firefox-nightly-stub&os=win&lang=en-US
The nightly allows this extension to be loaded. Thank, your suggestion prompt me to look for it!
"IMDb Search" extension installs for me on Developer Edition 126.0b5 and also with extensions.langpacks.signatures.required set to false.
Does it still happen with default settings in a new browser profile? Alternatively you could refresh your existing profile. Make sure you stay signed out of your sync account when testing.
Yes, it does happen with a new profile.
My Developer Edition version is also 126.0b5.zeroknight said

Yes, it does happen with a new profile. My Developer Edition version is also 126.0b5. Really weird, a new profile is indeed a blank slate. Although... ding ding! I have installed TAB MIX Plus, which requires 2 files in the FF install directory:
config.js:
// skip 1st line lockPref('xpinstall.signatures.required', false); lockPref('extensions.install_origins.enabled', false); try { const cmanifest = Services.dirsvc.get('UChrm', Ci.nsIFile); cmanifest.append('utils'); cmanifest.append('chrome.manifest'); Components.manager.QueryInterface(Ci.nsIComponentRegistrar).autoRegister(cmanifest); const objRef = ChromeUtils.import('resource://gre/modules/addons/XPIDatabase.jsm'); objRef.XPIDatabase.SIGNED_TYPES.delete('extension'); ChromeUtils.import('chrome://userchromejs/content/BootstrapLoader.jsm'); } catch (ex) { /* empty */ } try { ChromeUtils.import('chrome://userchromejs/content/userChrome.jsm'); } catch (ex) { /* empty */ }
C:\Program Files\Firefox Developer Edition\defaults\pref\channel-prefs.js

C:\Program Files\Firefox Developer Edition\defaults\pref\config-prefs.js
pref('general.config.obscure_value', 0); pref('general.config.filename', 'config.js'); pref('general.config.sandbox_enabled', false);
Removing them allows to install IMDb, and re-installing them enables TAB MIX Plus again, without disabling IMDb.
Interesting.
