I have a question (speculation) about having several Firefox based browsers installed on my Windows 64 PC. I have a Windows 10, 64 Bit PC with 64 Gigs of RAM. I've always had a habit of installing several versions of Firefox based browsers - all to no avail. However, as of recent, I'm finding that my browsers begin to slow down substantially after 15 minutes or so of browsing - please read on. Right now, I have the following 64 Bit Firefox based browsers installed on my PC - they are: Firefox Waterfox Floorp Librewolf I have quite a large amount of bookmarks saved, and I make sure all browsers have the same bookmarks. I have a half dozen or so of add-ons, and have tried - from time to time - to uninstall various add-ons to see if they were the cause of the slow downs, but none of that made a difference. For example, let's say I'm browsing for 15-30 minutes or so, and have a half dozen different tabs brought up. After awhile, things begin to slow down substantially such as delays in clicking on links and having it respond, or right clicking, etc. Browsing speeds slow down substantially also. Here is what I then usually do: 1. Create a new tab and type in "about:memory" and click on the save memory command. 2. Go into settings and delete cache. This normally does nothing to speed up things, and I find I have to just close out the browser, wait a few seconds, and bring it back up to things to get back to normal. This has me speculating - "Could" it be that having a variety of Firefox based browsers with similar data conflict with each other in some strange sort of way" Or is it something else? I know that having a bunch of tabs up can deplete memory usage, but as I mentioned above, I have 64 Gigs of RAM and never had this issue before. My SSD drive has 500 Gigs of storage, and only half is being used. Any suggestions or recommendations would be truly appreciated. Ben Herrmann Fuquay-Varina, NC
