User Reviews
It does what it says, and nothing more. It's basically an MVP that fills the name: it allows you to enable and disable extensions and themes.
Unfortunately it also doesn't have much to make me confident it's secure to use. The developer account links to a betting site, and I can't find any links to the source code.
I'd love to see this extension developed further. The existing UI is minimal to point of being non-existent. There are no icons or any info besides the name, type, and an on/off toggle. Themes and extensions are mixed together and for some reason themes are labeled as "plugins".
Unfortunately this is still the best (working) extension manager I've found for Firefox so hopefully it will get addtional features. Features like links to plugin settings, and categories/groups would go a long way toward making similar to the dozens of extension managers available for Chrome.

No way to sort. GUI requires having to scroll from one side to another to see whether an extension is disabled or not, AND you can click enable/disable until your blue in the ass and it does nothing. Check through Firefox's manager and you can do it while there and whatever extension you wish to enable/disable does not change.

It looks that this is the only working expansion to control expansions.
For better readability, perhaps it worth to make on/off buttons of different colors and not so bright.
It also uses a strange way of sorting. Not alphabetical and different from the usual FF extensions list.

Is Plugin and Extension Manager Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Plugin and Extension Manager requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Plugin and Extension Manager has earned a fairly good reputation and likely can be trusted.
