Several Websies Won't Work

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?

Many site issues can be caused by corrupt cookies or cache.

  • Clear the Cache and

Firefox will Use Custom Settings. Press the button on the right side called Show Cookies. Use the search bar to look for the site. Note; There may be more than one entry. Remove All of them.

  • Cache; Select Advanced > Network. Across from

Cached Web Content, Press Clear Now.

If there is still a problem, Start Firefox in Safe Mode {web link} A small dialog should appear. Click Start In Safe Mode (not Refresh). While you are in safe mode;

Type about:preferences#advanced<enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Then restart. Poke around safe websites. Are there any problems?

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.
