Hi Folks, Since Friday 22/9/2017 Firefox has been running extremely slow to say the least. I have tried all the suggested tweaks in about:config. I have scanned the Laptop with Malwarebytes, Windows Defender, Panda Security and Spybot Search & Destroy but they all found nothing the system is clean. I've refreshed Firefox twice and installed a clean version with a fresh profile but the result is still the same. The next step I took was to do a clean install of Windows 10 and yet again that did nothing it's still running as slow as an old bus. After the clean install I have replaced a few add-ons that took 3hrs each to download and install 1.8 & 2.0mb. I'm clean out of ideas and hair can someone "pleeeeeeeeeeaaaaaaaaaaase" help with this issue. "Thank you very much to anyone trying to resolve this issue it's very much appreciated cheers have a good one"!!! Paperfree!!!
