TB38.3.0, the Lightning disappeared between extensions. Relocation of lightning and update to 38.4.0 did not help. [was: my calendar disappeared]
I have Thunderbird 38.3.0 on a Windows 7 PC. For some reason any today my calendar with all my appointments simply disappeared. When I went to the Add-ons Manager, lightning was missing in my extensions. I didn't remove it myself.
I tried to reinstall it. After you restart Thunderbird, Lightning was back to the list of extensions (version 4.0.4.1) but I still have no schedule and no toggle button "today Pane.
I tried to remove and install again. Still no joy. Help!
That's what I'll try:
Determine the folder of your profile through the troubleshooting information.
In the top right of the Thunderbird window, click the menu button , then select help > troubleshooting information > profile folder > open folder.
Profile opens in Windows Explorer.
Close Thunderbird.
Antivirus real-time scanner snoozes.
Navigate to the subfolder of extensions and search for a folder {e2fda1a4-762b-4020-b5ad-a41df1933103}. This is the Lightning extension. Delete this folder, if there is.
If there is a folder "staged" delete it as well.
Launch Thunderbird and install again the lightning. For Thunderbird 38.4.0 the corresponding version of lightning is 4.0.4.1.
If it worked this time, turn anti-virus back on.

our and twitch.tv do load properly (no content displayed) deleted the cookies/cache, nodnsprefetch = true, ensured that no proxy, safe mode, did not help!
The approximate layout works very well, but the real tv-content (contraction) or the real message (ggroups) texts will not be displayed. Also, by clicking on the wheel of preferences in ggroups will display a small empty box instead of a drop-down list filled with stuff.
The pages all work properly in chrome.Note that youtube and google search normal, pages provider freemail, news pages and basically all the other pages I can think of work normally and 100%!
I use linux 64-bit, firefox 22. However, this problem is not new, it's happened with older versions of ff too. I'm just tired of pulling up chrome every time, so I decided to report it here for a solution.
Well, after you move a large number of files and the contents of the file autour, I found a solution:
Delete the line
user_pref ("dom.storage.enabled", false);
of prefs.js solved the problem.Thank you.

I can't Live Update my Max Total Security that I get the message "DB update failed download!» Max Support also did not help at all. Disappointing. What should do?
Do yourself a favor and remove the application. Mac do not need AV applications and at best, they will be not hard (but not good either) and at worst will corrupt your system / OSX's built in protection. Your concerns are malicious software that requires the cooperation of the user to install, not the virus.
For more information, please read this:
Ciao.

Menu start no longer displays options to shut down the computer, someone knows how to change that? The power options menu did not help.
When this happened to me, it was malware that didn't stop my computer, probably because she wanted to do something with it. I held the power button down until the computer is turned off manually, then I rebooted in safe mode - I run Vista - and ran some virus and malware programs until I found the beast and it crashed. You can also run a scan MS online at onecare.live.com, which was updated earlier this week. Moreover, I had not any data loss or permanent damage.
