Re: Firefox 57 Unbranded does not allow legacy extensions
Using an unbranded build of version 58, you can set extensions.legacy.enabled to true in about:config. This will enable legacy add-ons, but legacy APIs are constantly being removed, so your particular legacy add-ons may not function.

Dumby's hack broke in Fx 59.marty60 wrote:Is this working for you anymore?
A CB user got a few legacy extensions working in Fx 59 by taking the defaults\preferences\*.js files in *.xpi files and placing these *.js files into the folder with the channel-prefs.js file.
I got the Custom Buttons 0.0.5.8.9 fixed7pre and DOM Inspector Plus 2.0.17.1.2rc extensions working without Dumby's hack in Fx 58. I put the CB and DOMi Plus pref files into the folder with the channel-prefs.js file. I rather not use Dumby's hack in Fx 58 because it increases the startup time noticeably.
I set these preferences.
Code: Select all
// Disable Signing Requirement
// Enable Legacy Extensions
// Enable Non Multiprocess Compatible Extensions
pref("xpinstall.signatures.required", false);
pref("extensions.legacy.enabled", true);
pref("extensions.allow-non-mpc-extensions", true);

Disabling e10s may affect what you might or might not get out of legacy extension...
Fire 750, bring back 250.

Buttons that can't be added by webextensions can be added by userChrome.js scripts. No noticeable impact on startup time that I've seen.morat wrote:Custom Buttons 0.0.5.8.9 fixed7pre
