Mozilla broke protocol handler extensions

Question

Mozilla broke protocol handler extensions

mkovatsc opened this issue 8 years ago · comments

Mozilla made development and testing quite annoying and broke the support for protocol handler extensions in the Developer Version (FF50). Not sure if there will be a working Copper in the future...

Thanks!

Quick fix:

Open about:config
Search browser.tabs.remote.autostart.2
Set to false

Unfortunaltely this workaround doesn't work for me with FF 50.0.2, FF still complains about the unknown protocol.

Can you provide a screenshot and system information?
Under Windows it works with FF 50.0.2. I never received an error message.

Thanks for your prompt response! I did some more investigation and it turned out that browser.tabs.remote.autostart needs to be set to false as well (default is true with a newly created Firefox profile). Having that set, Copper works fine again. I'm using the x86-64 Linux package.

Since FF52 this autostart is disabled automatically when required by add-ons.

FF57, which is planned for September, might disable Copper for good, as they change to a new WebExtensions model for add-ons... so far no time to look into it.
