[RC] Failed to start new browser session - lock file still present on parent.lock

[B Unit]

I've been using selenium on windows-Firefox for a year without running
into this problem, but for the last two days I haven't been able to
run tests. I tried following some other similar threads but the
solutions either weren't specific enough or didn't work for me. Can
anyone help? Could this have anything to do with upgrading to Firefox
3.5.7 or Firefox 6?

Your browser may have updated to a new version. Check what you have,
and downgrade if so.

I'm using Firefox 3.5.7 on Linux but I don't have any problems. If you upgraded to firefox 3.6 however that may cause some issues. I just checked and the extensions that Selenium installs have maxVersion as 3.5.*
 <em:maxVersion>3.5.*</em:maxVersion>

You could try tweaking that to 3.6 and it *might* work. These should be there in some file called customProfileDirCUSTFF and customProfileDirCUSTFFCHROME in some file like selenium-server.jar.

Also, I assume you've already tried killing all the java and firefox (or firefox-bin) before retrying.

HTH,

Neha

Thank you for the help, I downgraded all the way to Firefox 3.0.1
(http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.0.1/
win32/en-US/) to get it to work. Hopefully I can find a middle ground
on the version so I can have both selenium working and Firebug (which
looks like it requires 3.5). Should a ticket/bug be filed for
selenium not working with the latest Firefox? Regardless, I'm more
than happy that i was able to get it working for now, thanks again.

I am glad I found this post, I had same issue and since I'm new to
selenium I wasn't sure what I did wrong.

Thanks.

Great discussion, helped to find solution.
Just grab new Selenium RC from http://seleniumhq.org/download/ and it
should work for Firefox 3.6
Works for me.
