This is usually due to an incompatible add-on:

http://kb.mozillazine.org/Gray_bar_below_status_bar

Does it still appear in safe mode (hold Shift when you launch TB)? If the TB on the old computer was older than the one on the new one, the transfer may have included an incompatible add-on.

Thanks! Since I had to reinstall the computer, I did not reinstall add-ons yet so maybe it is looking for an add-on which I did not reinstall?

When I try to relaunch Thunderbird with the shift button pressed it directs me to program reinstallation, as if I had not installed the program yet?

When I go to the expected location in the file explorer it locates Thunderbird in Users/Appdata/local but in File explorer I do not see the Thunderbird.exe file, even with the "show hidden files" box ticked.

To me it looks like I did not finalize installation of thunderbird properly, is this possible?

What do you suggest so I do not lose my latest profile, largely updated since I reinstalled (but without closing Thunderbird since, until the described problem occurred)?

Thanks again,

Stéphane

Hello there Stephane.vuillemeumier. We have read your message We try to help you.

If there was a not good installation Of it or a not complete one Than it becomes to be a failed update.

Please read this article :

Greetings Firefox Volunteer.

Thanks for your suggestion!

I am not sure if this is my problem, because I did not receive the error message in the support link you provided ?

i.e. When I reinstalled I did not get the message "Software Update Failed The update could not be installed. Please make sure there are no other copies of Thunderbird running on your computer, and then restart Thunderbird to try again."

Thanks again,

Stéphane

I then chose the corresponding profile (something that was not required previously if memory serves), also as per guidelines

Thanks! Since I had to reinstall the computer, I did not reinstall add-ons yet so maybe it is looking for an add-on which I did not reinstall? When I try to relaunch Thunderbird with the shift button pressed it directs me to program reinstallation, as if I had not installed the program yet?

I assume that you have tried to use an old profile on the new installation. On that profile settings were "mentioned" some add-ons or some settings which TB couldn't find them anymore and that might have caused your issues.

As you say you did a "reinstall the computer" then I assume you actually need only old general settings/mails so you might try a new profile instead to point to that old profile. After that: -abook.mab and history.mab (if you see those files also with .bak then get those ones) you need to copy in the new "fresh" profile (if you got those with .bak then in the new profile delete .bak) -mail storage - you can choose at "local directory" for each email account the (old) path where those mails are saved. Once this is done also old filters will be imported (as those filters are saved on those accounts)

Hello there sthepahane.vuilleumier

Your data is stored separately, in the profile so won't be affected by a re-install.

https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data?redirectslug=profiles-tb&redirectlocale=en-US

It s a after reinstall the program the icon loads but after restart the exe .file maybe disappears?

Okay.

If your add on is broken. Contact the add-on developer for support.

Hello sthapahane.vuilleumier.

Check again for Add-on or extensions. If something there of it.

“error message read <window <="" id="messengerWindow" p=""></window>“italic text'

A broken layout could also be the topic. see if the program works as it should after booting it in safe mode for thunderbird.

check disable all add-ons and reset toolbars and controls then make changes and restart.

does it not work in normal mode?

If so, you should re-enable add-ons if you have one-at-a-time and test for incompatibilities.

Greetings Firefox volunteer.

thanks!

Sorry not sure I follow, is the following step by step procedure what I should do - install thunderbird, but without setting uo accounts. - in the new thunderbird folder (in profile?), replace about.mab or about.bak and history.mab and history.bak with my old ones at the same location?

Do I understand correctly, these abook and history files contain accounts information so I do not need to set up accounts again?

>-mail storage - you can choose at "local directory" for each email account the (old) path where those mails are saved. > Once this is done also old filters will be imported (as those filters are saved on those accounts)

OK, that part I did in past computer changes, I think I know how to do that. I just liked the idea not to have to set up accounts again just pointing to an old profile, but that seems to have failed. So it's just the abook.mab and history.mab part of your message that I don't understand (see above), can you please clarify?

Thanks again,

Stéphane

Hello there

It seems that after such actions as rebooting after complete update from old version to 78.0 Or 78.2.1 that these entries also come up for example when changing the language input for Thunderbird. And get stuck.

With this same error message.

“error message read <window <="" id="messengerWindow" p=""></window>“</window>italic text'

Try to uninstall Thunderbird and install rename the installation it could be disappeared. As recommended.

can you start safe mode?

Greetings Firefox Volunteer.

Thanks again for all your suggestions!

Sorry, I didn't get this. Can you clarify what to do exactly after uninstalling, what do you mean by "install rename the installation"?

Thanks again,

S

@Stéphane: abook.mab and history.mab are only address book files. Your account settings are stored on prefs.js file - but that file also contain information about old add-ons and old other settings which might cause you those issues. So, sadly, I would recommend to set the email accounts again in a new profile. As steps: 1 set accounts 2 set path folders 3 get old .mab files

Assuming it's not OK for you to start over again setting all those email accounts then you can start that "imported" profile in safe-mode (hold shift button while starting TB - select no add-ons) and disable all add-ons that appear there. Restart TB.

Here is one more update: I have played on my TB with prefs.js files and I could get on a new profile "old settings" by copying them from last pref.js file - off course w/o the passwords (but I assume this is not an issue for you).

You might test as well like this with a new profile: 1. Start TB with old-imported profile and go to your profile settings: At the top right of the Thunderbird window, click the menu button (or use the regular menu at the top), then select Help: Troubleshooting Information. On profile zone click open folder. 2. copy prefs.js file on desktop (or anywhere) 3. create new profile with default settings recommended. Do NOT set any account. 4. on this new profile again "open folder" - locate prefs.js file created - and now close TB 5. on this new prefs.js file locate and delete all lines which start with "user_pref("mail" - the line before should be "user_pref("layers.mlgpu" add the first after should be "user_pref("media.hardware") 6. now copy from dektop prefs.js file (point2) all lines starting from first line with "user_pref("ldap" till the last line with "user_pref("mailnews" to the new prefs.js file (point4 and 5) instead of those deleted lines. 7. close/disable your internet connection 8. start TB - all old settings should be loaded (w/o passwords) 9. if all OK then get also .mab files from old profile to new one (with TB closed) and start back the internet connection

Hello there Stéphane.vuiluemier.

https://support.mozilla.org/en-US/kb/using-multiple-profiles#w_renaming-a-profile https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data

It was more sort of a option to change your installation name / profile name yes. To bypass.

I meant everything you got from Firefox or Thunderbird. Reinstall it after a good Uninstall of both and or one. delete every profile of it search good use a uninstall tool even your icone.exe may reappear after this.

https://www.thunderbird.net/en-US/thunderbird/all/ This one here.

It looks like that your update went wrong at :

<window <="" ^="" id="messengerWindow" p=""></window>

Take the uninstall button -Control Panel > Programs and Features Select 'Mozilla Thunderbird and click on uninstall. And choose the new version ,the URL in this box above.

Hello there Stephane.vuilleumier.

If you are not disside to delete the software and stay there. Try to use run Thunderbird in safe modus and hold the shift button. Then check if you can see any different.

http://kb.mozillazine.org/Safe_mode

Does a message appear in a dialogue box at the left corner? It can get you back on. Check in normal mode if there is still a problem.

If it works in safe mode, you likely have either an incompatible add-on or a broken layout. Launch again in safe mode, check 'Disable all add-ons' and 'Reset toolbars and controls', then 'Make changes and restart'. But you do not had installed any of them ,add on or extensions

In TB normal mode, is hardware acceleration enabled in Options/General/Indexing? If it is, uncheck the box and see if TB works properly in normal mode. That is an option to.

If not you can use

https://archive.mozilla.org/pub/thunderbird/candidates/78.1.0-candidates/build1/ It solves the problem?

Greetings Firefox Volunteer.

Thanks everyone who tried to help with my issue. I finally managed to reinstall without losing any folders/emails.

This is how it went for me: Restarting in safe mode (shift button pressed while clicking the TB application shortcut) worked and everything was still there, but per definition the add-ons likely responsible for the problem were disabled in this mode so I could not remove them.

Trying to uninstall/reinstall and removing the user_pref("mail"…) lines in the new pref.js and replacing them with the old ones as suggested by svlad2009 didn't work for me, in fact I couldn't get the TB program restarted after trying to do what was proposed.

I suspect they were too many issues with this reinstallation in TB 78 (too many changes with the TB 77 version I had?) so I went back to "the old way" of transferring profiles.

I backuped my TB profile folder with all data.

I uninstalled TB (taking care to remove *all* remaining TB folders everywhere, because if I didn't and reinstalled TB, the same error message <window <="" ^="" id="messengerWindow" p=""></window> </window> turned up

I installed TB 78 (internet connection turned off). I created all required accounts (both IMAP and POP type) from scratch, one at a time (only turning on the internet so that TB could verify settings).

I copy-pasted my old profile in a safe/trusted location on my computer.

In TB I changed the settings of the local folder for each account, one account at a time, to point the appropriate folders in my old profile.

And that worked! It took me a little while (maybe 45 minutes, checking step by step and one email account at a time), but that was straightforward for me - compared to the hours of trying to fiddle with the pref.js file, feeling completely out of my depth in the process ;-)

Thanks very much again to all who quickly provided suggestions on this one !
