Firefox stops responding when using dev panel on hh.ru site
When a user opens hh.ru / headhunter.ru (famous HR portal in CIS countries) in Firefox, and then opens dev panel and tries to interact with it, especially with the code inspect tool, the whole browser stops responding.
The problem persists even on a clean Firefox profile. Other browsers (Chromium-based) work well with the dev panel on the hh.ru site.
