Is it possible to save preferences in Firefox and switch between them?

Question

Browsers

In addition to settings, I also mean bookmarks, search results, history, accounts, plugins. Is it possible to save all this and then switch between saved sets. If not, in which browser is this supported?

Answer 1

1 - this is called "user profiles"
2 - supported in all browsers upd in all cultures - all

Chrome based

and Firefox . in IE and Edge with this gimor
- для Хром семейства

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Default"
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 1"
and so on...

полный путь тоже работает, а так же вставки типа %LOCALAPPDATA%..
- для FF
3 - you can save a lot of disk space. for FF , the reference profile is enough for me and only

7 files for the rest (8 can be)

key4.db
logins.json
sessionstore.jsonlz4
content-prefs.sqlite
favicons.sqlite
permissions.sqlite
places.sqlite

хотя многим, скорее всего удобно было бы сохранять и куки - cookies.sqlite
