Recurring Kernel Panic

[SolidStill]

Frequent kernel panics since installing the Tab Suspender Firefox addon. Thread backtrace identifies the corresponding BSD process as 'plugin-container' - which, in combination with the timing of the installation and subsequent panics, makes me fairly confident that this addon is the issue.

Note that 'AAA.LoadEarly.MouSSE' is the kernel extension in the backtrace (see crash report below) - this is a special kernel extension installed by "macOS Patcher" (This allows the installation of newer macOS versions on older unsupported macs)

Here's the full crash report:

Really hoping you can help me out here because the extension you've made is incredibly useful and seems very well designed. Thank you!

[Hau-Hau]

Hello @SolidStill, It seems like Firefox's plugin-container bug caused (probably) by Tab Suspender memory leak.

I'm working on fix but it can takes from 2 weeks to 2 months or more because I've decided to make big changes in project.

[SolidStill]

Thanks for filling me in @Hau-Hau 👍 Kudos on the project and your approach. I've "starred" the project so hopefully I'll be aware when you commit your overhaul. Thanks very much.
