Significant delays beginning two days ago

Posted

I have an HP Probook laptop with a Core-I5 CPU, 8 GB of RAM and a WD Black NVMe SSD running Windows 10 version 1809. it's about 4 months old and has been running fantastically. I use Firefox as my default browser and have had no problems with it until two days ago, when it suddenly developed a massive delay. it shows up in multiple ways. When opening a webpage, my CPU will jump to about 50% and I cannot scroll for a number of seconds, as many as 10 seconds. Also, highlighting/copying/pasting operations have as much as a 10-second delay before they appear on screen, and I sometimes cannot type in a search box for several seconds or text I do type doesn't appear in a search box for several seconds. I've tried refreshing Firefox and also starting it in safe mode with add-ons disabled, but the same symptoms happen then. I uninstalled and reinstalled and that had no effect. I performed a complete uninstall using Revo uninstaller, rebooted and reinstalled and even then it still has the same symptoms, even though I haven't added any add-ons or extensions. I've run malware scans and disk cleanup with no improvement. I can browse normally with IE or Chrome and they show none of these symptoms, but I prefer Firefox. Please help me determine what suddenly changed on July 20th or 21st, 2019. I've used Firefox for years and never had a problem like this, and no amount of refreshing/reinstalling/rebooting/disabling add-ons or extensions seems to have any effect. If it comes down to a complete format/reinstall of Windows, I'll likely just use a different browser but I'd really like to get Firefox working again.

hi kevin, please see if the following step can fix this: go to the firefox menu ≡ > options > privacy & security panel and under permissions check the setting to prevent accessibility services from accessing your browser and restart once.

That seems to have helped and I have managed to restore my bookmarks from old backups, but I'm having a little difficulty restoring saved passwords. I've copied the key4.db and logins.json files from a few different old backups, but none of them seem to restore my saved passwords. Any advice on this?

i'm sorry that i won't be able to help much about the passwords. the 2 files you've described are the correct ones that should hold your passwords when copying them over from an old profile or backup: Recovering important data from an old profile perhaps just be sure that you're copy/pasting while no instances of firefox are running...
