I called an administrator about your password problem.

As to the slowness, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

I'm not worried about the password, I had to create a new account just to post. The old log-in was probably over ten years old.

I'm not running 57, it's not even on my computer. With a clean install, starting in safe mode probably would be meaningless because there are no add-ons at all, and where can you go from here? There is not much to do if a clean install does not work right out of the bag, and by clean, I mean I stripped every registry entry for FF.

Using 57 requires me to install the latest version of Roboform which will not work for me. No legacy support will probably put the nail in the coffin for FF before long for me. Chrome supports Roboform without issues but i don't want to change. Maybe I have some conflicting software causing this problem but I'm not going to jump through hoops just to run the latest version, to me this version was under cooked and dumped on the market. Lots of complaints about no legacy support and freezes. though I experienced no freezes

@Gabe51, actually I was one of those trying it out before leaping as it also gave me Addon problems. But what your describing is hard to know since no one can diagnosis where the slowdown is coming from. So unless it was complete fresh install with no FF installed it will be hard to narrow done the problem here. I have FF57.0.2 and have no slowdowns as what your describing. So unless it can be logged this will be like looking for a needle in haystack problem.

Did you bother to read my complete post? *I think not*

The answer is that there was a issue in 57.0 this was fixed when people contacted us about it via instructions as to how to fix it. High Ram usage due to Accessibility Services (blind,hard to hear etc.) being turned on as default. This was then fixed in update 57.0.1 There is also another fix but that is on a individual basis of the persons system : Go the Menu then Tools --> Options --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 0 = No Multi-processor = slow again. Recommend 2 Restart Firefox after making these changes please. info : https://arstechnica.com/information-technology/2017/06/firefox-multiple-content-processes/

There was a Profile issue with wrong characters being written and this was fixed in current version 57.0.2

Please let us know if this solved your issue or if need further assistance.

Try to disable accessibility services in Firefox.

• Options/Preferences -> Privacy & Security -> Prevent accessibility services from accessing your browser
• https://support.mozilla.org/en-US/kb/accessibility-services

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

Try this try that? I think I will just wait for FF to get it right. (If ever) I'm running an older version and for now it will works without issue. Thanks for the effort but I'm not remotely interested in trying to make this work. Something caused FF to release this half backed version before it was ready. Downgrading back to my current version if this does not work is a PITA.
