i open firefox every time speed dial will be restart all the thing or empty and come out double bookmark

I would like to have an option to clean auto-backups registers and data. Just to save disk space.

I am using SpeedDial in Firefox 56.0, Kubuntu 16.04.3

And who uses Yahoo anyway?

If you can roll back this is the fix in fire fox to force multi threading, and FVD speed dial worked great, this new one is awful.

follow these instructions

If you're using Firefox 48 or later, you might be using e10s already.
Check about:support and look for a number higher than 0 in the
"Multiprocess Windows" entry. If you would like to opt-in, open
about:config and toggle browser.tabs.remote.autostart to true. On your
next restart, e10s should be active.

If you've tried enabling e10s following the instruction above, but your about:support
indicates that e10s is disabled (e.g., accessibility, add-ons can
trigger this), you can force e10s on for testing purposes. Within about:config create a new boolean pref named browser.tabs.remote.force-enable and set it to true. This is not encouraged, use it at your own risk!

In the 'PowerOff' tab in the settings the image at the bottom reads 'Enter passcode here to unclock' when it should read 'Enter passcode here to unlock'.

after updating too large vertical indentation between rows! Make it the same as for the neighboring horizontal cells.

I've lost 3+ years worth of tabs.

Firefox will automatically close immediately after checking for updates for add-ons.

Disabling FVD prevents that from happening.

I am using version 56.

Please revert.

Also please don't respond with;

Hi,

This is the simples option, not always help but we encourage to try. 

- Copy and paste in address bar about:support   - Select following http://nimb.ws/Vm5pjy  - Rename this folder to any name and restart Firefox http://nimb.ws/awxfuW BUT don't delete it. Just rename. 

If it won't help, let us know.

^ This does not work.

And please don't tell me to install eversync. 

Just revert, nothing you did with this update is worth shit to anyone.
