"Export tab groups" stopped working

[ricardoroehe]

Export tab groups does not work (clicking "Save backup" button does nothing).

There is another issue with the same behavior (#73) , but the problem still persists for me.

I also noted the "keyboard shortcuts" fields (Toggle Panorama View, Activate the next Tab Group, Activate the previous Tab Group) are empty. Pressing "reset" does nothing (it seems "disbale" does nothing too).

Another thing: the export stopped working after restarting Firefox. PTG was working flawlessly before the restart. So, I'm not an expert, but it might be incompatibility with some other add-on...?

My system: Firefox 88.0.1 (64-bit) on Linux Mint 19.2 Cinnamon PTG v. 0.8.12

I'm starting to think my issue is a corrupted Firefox profile - despite being able to open and use Firefox without problems. I tested by creating a new profile, with the same extensions I use, and PTB ran smoothly - exporting backup and all. So, that's that...
