Firefox has added electrolysis for multiprocess support, but the presence of an addon that does not support it will disable electrolysis. How do I know whether the addons I installed are compatible with it?

Use the Add-on Compatibility Reporter:
Probably the best way to test if your add-ons work with e10s is to use the Add-on Compatibility Reporter which will tell you if your add-ons are multi-process compatible and let you tell the developer how well they work. See this blog post for more.

Add-on Compatibility Reporter
After installing the ACR, you can report if the Firefox add-ons that you're using are working properly. If you notice that one of your add-ons doesn't seem to be working the same way it did in previous versions of the application, just open the Add-ons Manager and click 'Report Issue' next to that add-on to send a report to Mozilla.
Three weeks after a Firefox version bump, we will be prompting users using Aurora/Beta for information about whether their add-ons work. This will be a popup panel. The panel can manually be initiated by clicking the add-on icon in the Add-ons Bar.
Even if your add-ons all work fine, if they're marked incompatible, please let us know that they work fine by submitting a success report so we can encourage the add-on developer to update their compatibility information.
We'll collect all of the reports and let add-on developers know what users are having problems with, or if their add-ons seem to work just fine in future versions of the product.
Help make add-ons multiprocess compatible with Add-on Compatibility Reporter
Firefox is currently transitioning to a multiprocess architecture (e10s), which will give users a more stable and responsive browser. This transition affects certain add-ons, which must adapt to the new model or they won’t work correctly, and will be flagged as incompatible. We’re reaching out to add-on developers in various ways so they can check whether their add-ons are affected, and get support for updating their add-ons.
Now, there’s a way for you to help as well with outreach efforts, and that is by reporting incompatible add-ons.
Add-on Compatibility Reporter (ACR) enables you to tell us if an add-on works in a particular version of Firefox. Its reports have been a very useful tool for us in tracking incompatible add-ons and helping developers fix them. Add-on developers are also able to see reports sent for their add-ons in the developer tools. If you want to give it a try, we suggest that you do on one of the prerelease versions: Beta, Developer Edition, or Nightly. The latter two have multiprocess enabled for all add-ons by default, which is what we’re most interested in at the moment.
The latest versions of ACR have integrated support for multiprocess Firefox. Once you install the add-on, you will see which of your add-ons have declared multiprocess compatibility. You will also see if your version of Firefox has multiprocess enabled. The icons let you report if an add-on works or not.
