Comment (by cypherpunks):

 Replying to [comment:4 arthuredelstein]:
 > Having the same user agent is probably unnecessary in most cases,
 because it's probably impossible to make another browser (except maybe
 Firefox and derivatives) otherwise indistinguishable from Tor Browser.

 Oh, something else which I forgot that is also very important: Cloudflare
 shows captchas if you're using Tor and the user-agent is different than
 TB. You can easily reproduce this by going to https://blockchain.info
 which usually doesn't show a captcha with Tor Browser (or pick a better
 example). Then change the user-agent in `about:config` to the one for FF55
 for example, then click on New Identity, and go to https://blockchain.info
 again which will surely show you a captcha. You can test this with a
 variety of websites behind Cloudflare to confirm this behavior.
