Firefox is running slow and I keep getting a pop up window for some kind of bookmark synchronizer. How do I fix this and get rid of the pop up window? Help!!
Why do I keep getting pop up window asking for log in and password??? I didn't ask for this bookmark synchronizer thing. Please help ASAP! Very frustrating and bogging down my system. Help!!!

Did you start to set up Firefox Sync? To turn off Firefox Sync, please use the Options/Preferences page:
- Windows: "3-bar" menu button (or Tools menu) > Options
- Mac: "3-bar" menu button (or Firefox menu) > Preferences
- Linux: "3-bar" menu button (or Edit menu) > Preferences
- Any system: type or paste about:preferences into the address bar and press Enter/Return to load it
Then:
- Firefox 56-58: Click Firefox Account in the left column.
- Firefox 38-55: Click Sync in the left column.
Then if you have a Firefox account indicated there, try "Disconnect".
If Sync isn't (partially) set up, or that doesn't help, there might be an add-on in play. You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:
- Ctrl+Shift+a (Mac: Command+Shift+a)
- "3-bar" menu button (or Tools menu) > Add-ons
- type or paste about:addons in the address bar and press Enter/Return
In the left column of the Add-ons page, click Extensions. Then cast a critical eye over the list on the right side. Any system extensions that Firefox installs on its own are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything that looks as though it might be related to bookmarks or synchronization? If in doubt, disable.
Sometimes a link will appear above a disabled extension to restart Firefox before the change takes effect. You can complete your work on the tab and click one of the links as the last step.
Any improvement?
Are you using the Xmarks extension?
- "3-bar" menu button or Tools -> Add-ons -> Extensions

Option #2 appears to have worked. At least for the last 4 hrs. So it looks like I might be out of the woods and back to normal. Thank you!
