Firefox is painfully slow when running localhost
I am running MacOSX High Sierra 10.13.3 and the issue is with Firefox and Firefox Developer edition.
When I run a website from localhost to check if everything looks fine, Firefox is sluggish when it comes to opening menus. So slow I have to go to Chrome and Safari to check it.
So, Chrome and Safari both work great. Only Firefox is sluggish to the point where I can not use it for the purpose of website development.

Hi, not sure why you would have issues with local host unless your security software is working overtime on you when you work in local host. Myself, no problems, or issues. Could this have happened with a update to Dev Edition ? It maybe just a temp bug. If you do think it was caused by a a Dev update : file a bug report. https://bugzilla.mozilla.org/ Bug Writing Guidelines : https://developer.mozilla.org/en-US/docs/Mozilla/QA/Bug_writing_guidelines
To get to the issue suggest you :
- https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
- https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
Then uninstall the Developer Edition and see how Firefox performs doing local host. If all is well reinstall a new download of Dev Ed https://www.mozilla.org/en-US/firefox/developer/ and see how it performs.
To figure this out the Dev Ed has to go.
Please let us know if this solved your issue or if need further assistance.
