Browser does not popping out ||

[Christophe]

Hey Aman, I noticed the same issue yesterday and found out that one of the ZAP add-on updates seems to have broken browsers.

The add-on is “Linux WebDrivers” going from version 18.0.0 to 19.0.0. As part of that update, they updated “geckodriver” to 0.27.0, and I’m guessing that’s what’s causing the issue.

I’m doing some more digging to see if there’s an open ticket for this already. If not, I’ll create one with the maintainers of the package.

OK, yes there’s already been an issue opened with Mozilla for the geckodriver issue.

While we wait for a fix, there is a workaround:

1. Launch ZAP
2. Go to Tools -> Options
3. Scroll down and click on Selenium
4. Where it says “Binaries” add “/usr/bin/firefox-esr”
5. Click OK to save the changes. It might give a warning box saying that it couldn’t save because of “null” but it should still have saved. You can double-check by closing and re-opening the Options window and make sure the changes are still there
6. Try opening Firefox via manual exploration, and it should work
