Addon validation fails completely on large files

[Akkuma]

Describe the problem and steps to reproduce it:

File is too large to parse, upload an extension with a file larger than 4MB

What happened?

Receive the error "File is too large to parse", so cannot sign an unlisted addon that is a develop build that isn't minified.

What did you expect to happen?

Get a signed extension

Anything else we should know?

Can you please share the file you're trying to upload? Is this currently blocking you from submitting your add-on?

Closing this due to lack of information. Please re-open this if you're still experiencing the problem.

I received the same error when trying to have my extension signed:

Validation URL is: https://addons.mozilla.org/en-US/developers/upload/c65513ae305a4cdbaf4600dad60af212

Two files are larger than 4 MB in the extension:

These are ruleset files to be used by the declarativeNetRequest API, the only workaround I can see is:

• Do not prettify the generated JSON, which results in default.json shrinking to 3.6 MB
• Do not ship stevenblack-hosts.json DNR ruleset, it's still at 5.3 MB without pretty JSON

The extension package: https://github.com/gorhill/uBlock/releases/download/uBOLite_1.0.23.8118/uBOLite_1.0.23.8118.firefox.mv3.xpi uBOLite_1.0.23.8118.firefox.mv3.zip, and it's the first release of uBO Lite for Firefox which I expect to be as functional as the Chromium version.

Update: After some more thoughts, I did find a workaround to reduce the size of the DNR ruelset files. I could bring down the size as follow:

• default.json shrinked to 3.1 MB (from 4.7 MB originally)
• stevenblack-hosts.json shrinked to 2.5 MB (from 6.4 MB originally)

So it's no longer an obstacle at the moment to publish my extension on AMO, but eventually this still should be addressed as there is no documented limit how how large a DNR ruleset file can be.
