Why since the update to Thunderbird 38.0.1 nothing works properly?

Since the upgrade, opening a tab can take up to 5 seconds. When you type an e-mail, there is a delay of a second or two before the letter shapes. I can drag is no longer an email in another folder, and the 'move' tab does not work. When you write an email, it now by default "All address books" instead of what I put it. I could go on with more, but I guess you get the drift.
How can I go back to the previous version of Thunderbird that worked without any problems?
See you soon.

Note that downgrading to an older version exposes you to fixed in the new version security vulnerabilities.
Also, it will not address your problem in the long term, so to solve the problem, for example with a test profile, would be the recommended method for moving forward.

    The use of the battery has increased since the update to ios 10. Also, why can not disable the voice command. It's the most boring on the new update.

    Depending on what you mean by "voice command", either:

    Settings / general / accessibility / VoiceOver / OFF, or

    Settings / Siri / OFF

    As for your use of the battery, you can check what app pulls most of its use in the settings / battery.  A new version of the app is sometimes problematic, not necessarily iOS or iPhone.  If you see a unusual % of use of a particular application, or force-to leave it removal/reinstalling it or remove it until an update comes.  If anything seems unusual, it might be a problematic installation of iOS, in which case, you could backup your iPhone and restore it:

  • Why do I get restore window when opening firefox since the update

    Why do I get restore window when opening firefox since the update. I don't want to restore but it appears every time instead of my homepage as shown

    A likely cause is that you first close all Firefox Windows and then close the Firefox application.

    Some noted that closing of Firefox (Firefox > Quit) while the browser window is always open works for them.

  • Since the update for Firefox 4, I am no longer offers the possibility to save the tabs when closing making it much faster to access these sites when starting the next day. Why this possibility has been removed? It's a favorite feature.

    Since the update for Firefox 4, I offer more the ability to save tabs on shutdown - makes more rapid access to these sites when commissioning the next day. Why this possibility has been removed? It was a feature favorite and saved a lot of time.

    Firefox 4 records the previous session.

    You can use "Firefox > history > restore previous Session" for the previous session.

    There is also a button 'Restore previous Session' on the default on: Home home page.

    Another possibility is to use:

    • Tools > Options > general > startup: "When Firefox starts": "show my windows and tabs from last time '.

    You can set the preferences of warning on the topic: config page true via the context menu or toggle the value with a double click of the left.

    To open the topic: config page, type Subject: config in the address bar (address) and press the 'Enter' key, as you type the url of a Web site to open a Web site.

    If you see a warning then you can confirm that you want to access this page.

  • Since the update, the tab general in Options keeps opening by itself, involuntary.

    Since the update 4.2, the general framework in Options for guard opening by itself. Why doesn't he do that and ho can I get arrested? There is nothing there, I want to change.

    You can check the home page setting to make sure that you have not added the words: preferences page.

    • Tools > Options > general > startup: Homepage

    Firefox supports several home pages separated by ' |' symbol (pipe).

  • Since the update files now open in a new window and pinned tabs open all in the folder.

    Since the last update, now instead of simply to open a new page in the same tab when I click on a link, it opens a new tab. I also have a pinned favorite links folder, before I just click on it and scroll down to my link desired, since the update whenever I click on the folder, it just opens it in the folder. How can I fix it and God good, why cannot it be an option that stops updates to immediately change the previous settings like this done.

    I scrolled the basic options and couldn't find any way to address these changes, there are now very few options for tabs and pins.

    Yes problem seems to have resolved this self, probably a problem of update or something.

  • Since the update to iTunes 12.4.1.6 I don't see my purchased music. When I try to import my old playlists I get a message saying that the library is not a valid iTunes library. Thus, thousands of songs and hundreds of films and I can't see or play one.

    Since the update to iTunes 12.4.1.6 I don't see my purchased music. When I try to import my old playlists I get a message saying that the library is not a valid iTunes library. Thus, thousands of songs and hundreds of films and I can't see or play one. I see my movie library where it is stored on an external hard drive, but my music was on my iMac.

    Where all the playlists gone and why didn't appear my entire music library? I checked the preferences and iTunes points to the correct folder, BUT only my music purchased appears...

    Same thing happened to me. I tried to replace iTunesLibrary.itl with an older copy, but that has not worked. Then I tried to return a version by resetting the Time Machine's iTunes app, but it would allow me to edit or delete iTunes because it is part of Mac OS X.

    So, I can not sync my iPad or iPhone, update all apps or find my music, that is, the course of the odf, still on my hard drive. ITunes just can't see the library.

    Hello

    Go into the Contacts application and ensure that it uses the same account synchronization like the iPhone and other devices you may be using.

    Also check the part of the accounts of the Contacts application preferences and make sure that it's only using one account.
