I have noticed lately that when I have the Malwarebytes browser extension activated in Firefox, browsing is slowed down, and in some cases a site asks to reload. For example, Twitter/X takes about 10 seconds to finally load new posts, after which the site works normally. I have determined that Mbytes is the cause of the problem by running Firefox in troubleshooting mode. When I turn the Mbytes off in extensions, the problem goes away. However, if I turn Mbytes off for a particular site by disabling current site protection, AdTrackers, Malware, and Scams, the site still loads slowly. Again, turning MBytes off in extensions, does allow the site to load quickly. The problem I'm having does not occur when using MBytes in Edge or Chrome. I have tried all the suggestions like clearing cache and cookies to no avail. I don't know if the problem is with MBytes or with Mozilla Firefox. I've tried turning off all sorts of features in MBytes with no results. I have Firefox version 122.0.1 (64bit). My wife's computer using the 32 bit version of Firefox, and she has no problem with Mbytes.
