I have a HP laptop 15-BA009DX with a Firefox problem. I noticed that the newest Firefox release takes one of my backed up bookmarks that I restore - causing the folders to "leak" the bookmarks out of the folders. The result is a list at the bottom of the bookmarks menu containing several hundred bookmarks. It seems to only happen when you restore a bookmark .json file. I Loaded the Extended Support Release (ESR) version on my laptop and discoveredf that it doesn't have this bookmark "leak" problem. I tried to install the ESR version on my other (standby) laptop in place of the "regular" version to fix this bookmark folder "leaking" but the ESR version appears to not completely install. I can't go to any web page and I can't access the Tools > Options page. When I select the "Options" choice, it doesn't do anything. I have tried to uninstall and reinstall both the ESR version and the "regular" version several times with the same result. I frequently get an install error message similar to "VCRuntime140_1.dll not found - Reinstall can fix this". I am familiar with computers but I'm not a techie. Installing this should be a no-brainer, but I am baffled why it won't correctly install and work. Any Idea what is causing this problem? Thanks for your kind reply.
