Improve performance when JIT is disabled

### Issue Details

My browser disables JIT by default, including extensions. This is done for security reasons since many browser vulnerabilities are in JIT. This lack of performance is noticeable when you enable/disable filters, which takes way longer.

### Proposed solution

Improve performance without JIT .In uBlock Origin Lite I did not have this same issue for example.

### Alternative solution

Allow modifying filterlists and then clicking save changes once, since that would save some waiting time. But this is not ideal and does not address the main concern.
