If JavaScript is not enabled, you must have a content blocker extension which is disabling it. Such extensions can have that feature or the whole extension disabled.

Hi, Terry - I should have added that I disabled the ad blockers, the ones recommended by FF.

I have spent hours on the Internet searching for a solution, but to no avail.

Please note, that I am not a computer programmer, just an average user. So, technical terms confuse me; e.g. what is a "Content ...."? It would be most helpful if some direction were given that I might be able to follow.

If I may have the temerity to suggest that FF to Extension designers that they vet there programs, and disclose how they might interfere with popular programs, such as Javascript, much grief would be prevented.

I had a BSOD that would appear almost every day. After searching the Internet, it seemed that I might have too many extensions a nd some may interfere and cause crashes (I only used FF recommended Extensions, and felt safe) could be the problem; so I disabled all. Now, the BSOD occurred all through out my Internet usage. More lengthy Internet searches suggested my system was corrupted, so when it was suggested and I ran Scan Health and DISM, everything cleared up. It was not a piece of cake; most directions started off vaguely or incomplete, or bogged down within the directions, or were for different Windows programs., or assumed readers were proficient in performing tasks without further directions. I copied them all, and cobbled a workable program. It amazes me that programs are not revisited for updates.

I bore you, and I profusely apologize, but as a member of the un-washed masses,I do need more direction, much like feeding pablum to a child..

Thank you, Nick M.

You didn't add the Troubleshooting Information with the extensions list, so we can't check if you have extensions that can possibly cause issues. All content blocking extensions (recommended or not) use a filter list and always can block essential content and you always need to be aware and if necessary disable the extension on a specific page.

You can create a new profile as a quick test to see if your current profile is causing problems.

See "Creating a profile":

• https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

If the new profile works, you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

I see you've had challenges for over a week. In an earlier thread, you wrote:

Hi, Cor-el - Shortly after sending my request for help, not being able to use the computer, I decided to bite the bullet, and after laboriously copying Extensions and Settings, I re-installed FF. After inserting whatever I thought I might need, I checked into desktop. Lo and behold, there in the upper left was a folder, with old data. I haven't checked it out, but first chance. Sheer genius! All may not have been done in vain, as in other times, I have found errors in transitioning data.

If you made manual changes to files in your profile folder, that can sometimes create weird issues.

cor-el's suggestion to test with a new profile -- that you hold off on customizing, hold off on even connecting it to your Firefox account -- would be helpful to determining whether those sites where you get a message that you need to enable JavaScript have become broken in Firefox, or whether it could be a setting/add-on issue.

The same problem just turned up for me. I noticed a (new?) hexagon with JS inside it in the address bar that you can click to turn javascript on. Seems strange that it overrides the about:config parameter but it solved my problem simply.

Hi dcfavero

That icon with a JS inside is likely coming from a content blocking extension you installed that can block JavaScript and isn't part of Firefox.

My guess would be that the new behavior is related to one of your add-ons. If you hover your mouse over that address bar button and right-click it, there should be a "Manage Extension" option to open its Details panel on the Add-ons page so you can check out what it is.
