Hi, thanks for all the feedback. Some problems may indeed occur with the change of theme, every report helps me to improve the platform.
For the form fields in focus, the problem must be fixed in dark mode, in light mode, the problem wasn't there I think.
As for indexing with Dynamic Designs, I've restarted indexing and the problem has been solved.
As for your Firefox crashing, I think the problem is local, I've had no problems with that. Try clearing the cache and changing browser. If the problem persists, let me know which pages are affected so I can check what's on them.
Best regards.
