From where you have checked the plugin update?. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Hi amitshree,

I appreciate the prompt reply. I'm using the Add-ons Manager in FF and when I click the link at the top of the page I am sent to a page I hadn't seen before. The url is https://www.mozilla.org/en-US/plugincheck/. The same location I arrived at using the link in your reply. It is just an info page and does not list any of my plugins. In the past, following the "check" link in the Add-ons Manager gave me a page full of my plugins and I was able to update when indicated. Don't know if it matters but lately the update page had been showing that the some plugins were up to date and maybe half had a tab which said "Research." I haven't seen a plugin needing updating for several months. Still I would think that was the right place to determine if my plugins were up to date. If you or anyone else has any further ideas I'd appreciate hearing them. Thanks.

Can you try reset feature?

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Thank you.

The reset worked. I'd done a reset yesterday and I'm guessing that maybe one of the security/privacy add-ons I recently installed got in the way.

Do I need to start a new thread to ask how secure FF is and what security/privacy/adblock/popup/scripting blockers are needed and trustworthy?

Either way, thank you for your prompt assistance in restoring my update capability.

glad your problem is solved. btw you can use AdblockPlus to prevent unwanted adds. https://addons.mozilla.org/en-us/firefox/addon/adblock-plus/

I'll get Adblock Plus, thanks again.
