I want to search in plugin-container of firefox some aob but what i done until now it too slow .. first method was to get all memory pages with VirtualQueryEx then to read a block of memory (1024) witch work but it take ~20sec... so now i want to inject a dll in to the process because memory read is slow and i use VirtualQueryEx too for the start address and the block size but when i call the pattern function it crash ...

so do you have better solutions for plugin-container(use ~400MB of memory)?
