Ever since I updated to FF 54. I couldn't get the following websites to load properly: MapQuest, Constant Contact and Mail.com. I think there's something to do with Java.

MapQuest--Can't access anything, cannot get the log-in or Get Directions options. Constant Contact -- After log-in, nothing will load, just blank on the pages Mail.com-- Once log in, cannot open/delete any emails

I don't know if there are other websites being affected. All the above worked fine before FF54. And they all work fine with IE and/or Chrome.

Any suggestions/comments will be much appreciated.

Thank you.

Actually, I went to about:config and toggle "javascript.block" and now it said 'javascript.enabled". Everything is back to normal now, at least for now.

There definitely is a built-in preference called javascript.enabled which needs to be true, or else a lot of the web will be broken.

I don't think there is a built-in preference called javascript.block -- maybe that's associated with one of your add-ons?

That maybe. I didn't really recall what's the exact name of that, I know it's something "block". I just went to about:config and search for "java", and then saw it.

I haven't added any new add-ons for a long time and this issue only happened after I updated to FF 54.

At least it's working now. If the issue comes back, I'll post it again.

Thank you.
