Firefox Extension Problem.

I recently installed F.B. Purity - Cleans Up Facebook 23.0.0.
It's a Legacy extension and I'm using Firefox 56.0.2. But it doesn't show when I open Facebook.
Is any one familiar with this extension?

According to their website, you need to install the latest version v23.4.0. If that doesn't resolve your issue, they suggest to try the following:

• Refresh the page and/or close the browser and re-open it.
• Clear the browser's cache.
• Check if the 'open links in new window or new tab' option is turned on and, if so, turn it off.

If none of these work, the F.B. Purity developers suggest that you download an addon called eCleaner 1.4. After it is installed, remove FB Purity, then click on the options in the eCleaner. You'll see a list of addons you have or had installed. Highlight FBPurity and then click "Clear Selected", close the addon and re-install FB Purity

Here is a link to the F.B. Purity troubleshooting page if you'd like to read over it for any issues that may closely resemble your own. Good luck.

 

I use this with Chrome with great success. You may have to update Firefox to 58.0, as it is recommended to as there are known vulnerabilities with previous versions.

I just installed it in FF and it shows up OK, but using 58.0

 

ummm, thanks for that

 

Well I removed F.B. Purity, restarted Firefox, re-installed F.B. Purity from the official site, and it's working.
I now have version 23.4.0.0 and it's killing all the crap on Facebook.
But for how long...

 

Firefox 56.0.2.
F.B Purity 23.4.0.0.
