Very odd. Right click on email in list should open a drop down selection. Usually a crossed line through something denotes that it is marked as deleted in an imap mail account.

See if there is a conflict with an addon. Restart Thunderbird in safe mode. Help > Restart with addons disabled.

then perform the same test; right click on email in list. Do you get the drop down, if yes, then one of your addons is causing the conflict. You would have to disbale each in turn to locate which one is the problem. Maybe the addon needs updating. Report back on results.

Well, I've restarted Thunderbird in safe mode - and it's ok. After that I've restarted it in normal mode with all addons on - and it's ok as well.

Silly me. It seems that I should just have restarted Thunderbird from the very begining to fix this bag.

Nevertherless,Toad-Hall, thank you for your help!

Problem is solved.

Hi everybody, Thunderbird stoped to show the context menu on the mail list recently. Right click just prints the crossing line. What the problem could it be? Thanks anyone for any help. Win 8.1 64 Thun 31.3.0

I have the same problem too. When i restarted with addons disablem problem dissapeared but when i switch to normal mode and disable all off the plugins and addons the problem still remains. Please help.

eltomasso:

If you are using a theme you installed then disable that theme and only use the 'default' theme.

If you are already only using the Thunderbird default theme then try this:

Make hidden files and folders visible:

• http://kb.mozillazine.org/Show_hidden_files_and_folders

In Thunderbird

• Help > Troubleshooting Information
• click on 'show folders' button - a new window will open showing Profile folder.
• Close Thunderbird now - this is important

Look the following two files and delete them.

• session.json
• localstore.rdf

Close window - top right X Restart Thunderbird.

Report back on results.
