Could a version of requestpolicy be made, supporting all versions of seamonkey 2.53 ?
The 0.5.27 version only gives a grey flag for all sites in seamonkey 2.53.16.
For versions <= seamonkey 2.53.16, the 0.5.28.1-signed.1-signed Info worked well.
However, now almost all content is blocked in seamonkey 2.53.17 as soon as requestpolicy the 0.5.28.1- is enabled, with no option to switch it on.
RequestPolicy/requestpolicy#476
So, preferably, a newer RequestPolicy could be made working.
I don't know how to debug plugins, but I'm willing to learn.
