How to make ReCaptcha readable with SlimerJS

There are two kind of versions of SlimerJS: standalone and lightweight.

• SlimerJS standalone version is recommended whether you have Firefox installed or not. The standalone version depends on operating system (OS) and architecture.
  For Windows: [download.slimerjs.org]
  For Mac: [download.slimerjs.org]
  For Linux i686: [download.slimerjs.org]
  For Linux x86_64: [download.slimerjs.org]
• You can use the lightweight version if you have Firefox installed. You can download the latest SlimerJS lightweight version here, choose slimerjs-x.yy.z.zip file (for example: slimerjs-0.10.3.zip). But because the lightweight version depends on your Firefox installation, breakages are possible in the future, you're on your own if you choose the lightweight version. You can use the lightweight version for all operating systems. If something goes wrong, make sure you're using the one that compatible with your Firefox browser, usually it's the latest one. To check SlimerJS compatibility, open "application.ini" file in your SlimerJS installation folder, it's in "Gecko" section (MinVersion, MaxVersion).

Steps to integrate SlimerJS with FRD. We use standalone version (0.9.6) for Windows as an example:

1. Copy slimerjs-0.9.6-win32.zip (for Windows standalone version) to "tools" folder inside your FRD installation folder.
2. Extract slimerjs-0.9.6-win32.zip. You'll get slimerjs-0.9.6-win32 folder, rename it to slimerjs.
3. Update recaptcha plugin to at least version 1.1.0 (Help -> Check for new plugins).

The slimerjs directory structure will look like this in FRD in portable mode:


Captcha without slimerjs:


Captcha with slimerjs:

------------------------------------


Starting from version 1.2.0, recaptcha plugin also supports NoCaptcha ReCaptcha which is used for example in TurboBit plugin.
How to use recaptcha plugin for nocaptcha recaptcha:
1. You will be presented two windows. Do not close them.
2. Click on "I'm not a robot" checkbox.



3. Choose the correct images based on the instruction/description. Then click "Verify" button.



4. Finally click "Submit" button. The two windows mentioned in point #1 will be auto closed.



Note to devs: In order to make it works inside IDE, you'll have to copy the slimerjs folder to the "lib/tools" folder inside plugin's source code main folder.

Nice job tong2shot !
If I understood this correctly, SlimerJS is a Gecko browser
simulation approach for FRD, so that when it connects to
various filehosters in free mode, its recaptcha plugin gets
served easy to figure out recaptchas (I almost exclusively
got the "street number" type), as if the FRD user was using
a standard web browser!

OS: WinVista SP2 x86 en-US
Installed Firefox: 24.8.1 ESR
(I know it's deprecated, but it's the last non-Australis ESR;
98% of websites work fine, plus I do not use it for sensitive
data - I have much newer Fx versions in portable PAF mode
that I use when safety is a concern...)
JRE 7u40 (x86)
FRD 0.9u4
recaptcha.frp 1.0.5

I followed to the letter your instructions, opting for the
"slim" slimerjs-0.10.0pre.zip file!
I then backed up recaptcha.frp v1.0.5 (the latest version installed)
and installed your attached v1.0.6.

I googled for filejocker links, this got me to:
[www.akiba-online.com]
(a Japanese file-sharing site of all things!)

All three of the provided links worked a treat in FRD
A small window, induced by SlimerJS, briefly pops up,
then it autoexits and the FRD recaptcha dialog window shows up
with an easy number-type query...
So, all's well at my setup

The only small caveat is that as recaptcha.frp is a "system"
plugin, it doesn't show up in the list of installed plugins,
so its update can't be turned off by the user; hence, in an auto/
manual check for plugin updates, v1.0.5 always shows up
and has to be deselected...

Congrats!

Updated the attachments, nothing critical: forgot to remove temporary java script files, check SlimerJS existence.

Thanks for the feedback

I think it's pretty safe to upload the plugin to the official plugin repository. The old recaptcha implementation is used as fallback if the plugin doesn't detect SlimJS existence or if there is error in SlimJS recaptcha execution. But let's just wait for few days to get some feedbacks, better ideas/approach.

This is very nice.

I just had a crazy idea, and I have no idea if it would work, but JavaFX has a feature called WebView, which is basically supposed to be a fully fledged WebKit browser. I have no idea how ReCaptcha detects bots, but WebView/JavaFX has the advantage that it's included in Java 7 and later, so no need for any extra programs or libraries.

hi all, I'm new to the forum, I read this post, the plugin folder can not find it in the folder of FDR, where I post the files recaptcha.frp? I have to create a new one?

I tried JavaFX/WebView but I can't make it works with local content. Interestingly if I load page (remote content) that uses ReCaptcha (for example: [www.nitroflare.com]), it's not detected as bot. I'm not sure what's wrong. I gave up on writing WebView recaptcha implementation.

@sam2tko:
- Put slimerjs folder inside 'tools' folder.
- Help -> Browser to log file, then go to parent folder twice, you'll see 'plugins' folder.

"Help -> Browser to log file, then go to parent

you can attach a image of example?

Browser of Firefox folder?

Start FRD, click "Help" menu, then choose "Browse to log file". You'll be presented a new Windows Explorer window, in that window go to parent folder twice, you'll see 'plugins' folder.

I'm not using Windows at this moment, I'm using different file manager (not Windows Explorer).
