H, : Please consider turning on send info to Mozilla from with in Firefox before posting a question. This helps us help you. I have no info from your system that would help see things that cause issues.

give this a try since I have no info : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

• https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
• https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer

Reinstall with Current Release Firefox 59.0.2 with a Full Version Installer

• https://www.mozilla.org/firefox/all/

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

Note that using System Restore can cause your Firefox installation to get corrupted because only white-listed files are restored.

• always be cautious with using System Restore.
• you may lose data in the Firefox profile folder like .js and .ini files
• you may need to reinstall affected software

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

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks and history and Cookies and passwords and cache and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Hi thanks, i tried your suggestion and it does the same thing, begins to login, the scroll bar advances and stops almost at the end and never finishes

I have attached screen shot of outlook where it stops screen shot of my system details and screen shot of showing i do have send reports to firefox

thanks

Success I tried the last solution...using safe mode it appears the part about going into history and selecting "forget info about this site worked. Note: I had a little problem finding where you mean this so will add this direction: select "history from menu bar select "show all history" - 1st item right click on file associated with outlook i.e. "sign in" or "login live.com/signin select last item "forget about his site"

i restarted firefox in normal mode and it works fine

thanks so much, i really really appreciate it as i hate using IE or Chrome

hi been able to sign into outlook with no problems for last ~ 9 days, today signed in first thing no problem and then went to sign in again and got the same problem as above. I went into safe mode and "forget about this site" and logged in sucessfully.

There must be a bug somewhere with outlook and firefox hope the fix continues although it is annoying

not sure if someone should/can look into what is causing this

thanks bob

Do i have to start a new topic for this or is someone on FireFox going to bring this up as a continuing bug Please let me know, so that i am assured it is being adressed by the powers that be.

it looks like others are having the same issue

bob
