e10/multiprocess mode grayed out in Firefox Dev
I'm using Firefox Developer Edition and I'm wondering why I can't enable the e10 mode. I've tried force disabling accessibility. My only guess is that my addons aren't compatible with it. I use quite a few privacy-oriented ones (uBlock, HTTPS Everywhere, BetterPrivacy). Is there a way to tell which addon is causing the issue without going through and disabling them one by one? Any info would be appreciated.

You can check the multiprocessCompatible flags with scratchpad in browser environment.
Instructions:
* open about:config
* set devtools.chrome.enabled to true
* tools > web developer > scratchpad
* environment > browser
* edit > paste (i.e. copy and paste code snippet)
* execute > run
As an example:
Instructions:
* open about:config
* set devtools.chrome.enabled to true
* tools > web developer > scratchpad
* environment > browser
* edit > paste (i.e. copy and paste code snippet)
* execute > run
Code: Select all
AddonManager.getAddonsByTypes(["extension"], function (aAddons) {
var list = [];
aAddons.forEach(function (aAddon) {
if (aAddon.hidden == false) {
list.push(aAddon.name + ", E10 compatible: " +
(aAddon.multiprocessCompatible ? "Yes" : "No"));
}
});
alert(list.join("\n"));
});
DOM Inspector, E10 compatible: No
Greasemonkey, E10 compatible: Yes
UAControl, E10 compatible: No
Tab Mix Plus, E10 compatible: Yes
Custom Buttons, E10 compatible: No
Stylish, E10 compatible: Yes

Tried this and get:
/*
Exception: ReferenceError: AddonManager is not defined
@Scratchpad/1:1:1
*/

You are running in the content environment, not the browser environment.

Instructions:
1. open about:config
2. set devtools.chrome.enabled to true
3. tools > web developer > scratchpad
4. environment > browser
5. edit > paste (i.e. copy and paste code snippet)
6. execute > run
Did you forget steps 1, 2 and 4?

This addon by Mozilla tells you whether your addons are compatible with e10s or not.
