I was using phpmyadmin to export a database on-screen. When I initially clicked the export button it tool about 10 seconds for the exported SQL frame to show. Once it did, I clicked inside the frame to select all, and the browser hung. I had multiple tabs open (at least 15) at the time. It then came back from 100% CPU usage, and I could use all the other tabs, but when I click inside the SQL text iFrame, it hangs again for another 5 minutes.

Reproducible: Always

Steps to Reproduce:
1. Export a database to screen in phpmyadmin
2. click inside the iFrame
3. browser hangs

I just exited FF, and the re-started it. Tried the phpmyadmin export again without any other tabs open. Same result.

Can you please test in safe mode? http://support.mozilla.com/en-US/kb/Safe+Mode

Same results. Although this time it let me click inside the frame without issue (i think), but when I did ctrl-A it hung, consuming 100% cpu.

I guess this could be an issue with the size of the database I am viewing. It has some fairly large data sets in it, but I would want firefox to be a little more graceful about displaying/selecting large content.

Stephen, is it better with version 4 beta? http://www.mozilla.com/firefox/beta/

This issue appears to be resolved in the version 4 beta. I just tested it and was able to click on the text area after the export with no lockup.
