In terms of tabs, I rarely have over 30 tabs open. The moment I feel like I'm getting overwhelmed with the number of open things, I close all tabs that I don't absolutely need.
Seeing it's not signed by Apple, I was wondering if you'd be open for a donation to get you a proper account so the app can be distributed more "solidly" without Gatekeeper in the way.
Let me know. More than happy to get you in there.
Would be practical to have a unified way to install extensions in all of them
For example, faking location data, fonts, browser version, user agent, ssl certificates, available browser features, etc. Different anti-detect browsers offer different sets of features, but none will allow you to, say, pretend to be a Firefox user on Linux when you are a Chromium user on Windows, because it is possible to detect the engine and underlying system based on JavaScript and CSS behavior, if the website really wants to know that.
AFAIK, the most common use case for anti-detect browsers is competitive research, bypassing restrictions (not just location-based), and emulating specific user profile.
I can't seem to figure out how to stop and start browsers while restoring my sessions, i'm I missing something obvious?
What do you mean by "Stop and start browsers while restoring my sessions"? You should be able to start and stop the browser as long as it's not updating. If there is an update and you decide to install right then, you won't be able to open any profile that uses that browser during the update.
If you mean importing an existing profile, I haven't added that yet. But it's at the top of my list!
And if you mean something else... Then I'm not sure. Please either share more details or create a bug report if you feel like this is not the correct behavior.
