amazing extensions, also nice that is runs in local.

The only form filler I could find that actually was able to fill forms! Thank you!

While it does the job, it also eats a lot of resources in the background (could take up gigabytes of RAM and a CPU core for nothing) and does few requests for some reason. Which not only thrashes console with warnings when you work locally, but very concerning as well, because why would an extension like this would make any XHR requests at all?

I got rid of it and do not recommend it. I cannot seriously support my claim since Firefox resource manager does not show which extension takes resources, but my browser got significantly better after I disabled it. I advice fellow Firefox users to look for an alternative.

Its cool as it fill name and email with dummies of the same type and not just any random text

I absolutely love this addon! It decreased the time spent testing things dramatically and makes life so much easier. The $3 pro license is 100% worth it and I will be recommending this addon to all my coworkers.

This is one of the most comprehensive, feature rich and well made autofill add-ons I have ever stumbled upon.
Easy to use with great interface and autofill hotkeys.

This is far, far better than all the other form fillers i've tried.

overall is great and love the learning feature. Would also be great if cities and countries provided real existing data, and not some made up cities that don't exist.

The input generation is really good.
In addition the shortcut to fill the entire form is very nice.
However making this more intuitive (by adding the option to the context menu) or by stating it directly,
users would immediately know how to do this.
Given this seems to be the most important and most common use-case the amount of effort should be minimal.
Like single clicking on the browser toolbar icon or adding right-click "fill entire form" support.
However, since I now that it works, I am fine. However it seems to be a UX flaw for starters.

tl/dr: Absolutely wonderful extension.

Pros:
1) powered by faker.js library capable to generate almost any data for dozens of different locales;
2) extensible with javascript, so it can do anything, ANYTHING YOU WANT (except sandwiches, believe me, I tried);
3) supports custom inputs which means you can fill previously filled forms with one (well, actually two) clicks;
4) supports using window. properties, so you can generate logically bound data (generate (gender) male -> (full name) John Ronald Reuel Tolkien -> (initials) J. R. R. -> (email account) jrr.tolkien@example.com and so on) with idk, 3-5 mins of coding.

Cons:
1) can autodetect inputs as long as their name or id are exact same as generator name;
-----My mistake, but i doomed to use this extension with crapcoded apps, so I'll never see this feature working-----

2) currently you'll need to switch locale manually in the settings (this matters if you need both localized and english generators, like chinese names but latin emails).
-----It appears i was wrong, see developer answer.-----

Edit:
I need to be more careful with my statements, so I'll just add 2 Lorem ipsums to overall score.

12 Lorem Ipsum / 10

Good. It is very helpful.

All of it

This plugin only works with proper HTML inputs. It won't insert content into WYSIWYG editors (any divs that are made to be editable via JS) nor javascript alert popups.

Also author apparently refuses to add an auto-fill option which is quite a deal-breaker if you're into automation and speeding up your tests.

Overall... decent plugin if you're not doing much and working only on a short, basic HTML forms. Pointless otherwise.
