# 3715 Undefined Errors Can Occur in Certain Browsers

---

For no apparent reason, after testing with compression, now in FF I get random errors of variables that do not exist.
In Safari does not work either ....
I install FF again, and still does not load the project. (version 18.) (has errors)
Review all project files to see if I had been "garbage" by the testing that I did, but I did not find anything unusual.
Delete all the contents of the Output folder to make sure the "js" was new and does not work (always talk about FF and Safari).
I decided to re-install EWB 1.01 Build 2 and everything worked again Ok. (including compression).
