I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

Hello there We have read the question We try to help



To start solving the problem, you can try clearing your computer's cache and also clearing your Thunderbird software's cache.

Do you still see this information on your tabs for at least a second just before closing? It could be your session.json.file that might need a refresh or suffered a crash today. Apparently this clearly presents itself as a crashed topic at the moment where use of these tabs via Thunderbird is used by them and is ultimately written normally to the session.json files, which in turn is a clear problem when used with its Firefox software. another process name is where it is the sessionstore.js. This is simply written away and not at the last moment of use, as with the Thunderbird software.

You can try to delete these files regarding session.json and the adjacent xulstore.json then try to restart Thunderbird if needed. you can also try to enable the read only option on these files box and leave it off in the settings in this environment of these settings of session.json and xulstore.json

Hello there


The question to you was whether you can perform these actions such as backing up your inbox messages from your PC safely on a USB or external drive or on the desktop in a new folder itself?

We can secure with the back up of these files and then look at your executable files the msf. Files ,before you delete them then your inbox will be restored, hopefully for new use. The question for you is to implement this?

This would be a precaution for your inbox.

Your Antivirus program =(av).

Performing the designated topics is to run your computer with the Thunderbird software to get it working properly again. You can participate in the above topics so that you can use it again. If you prefer the quick way, the choice is yours, you can also backup the entire file of your spindles and messages in Thunderbird. delete the account and reinstall the software. This is mostly done among young people on the internet? Don't forget to save your credentials for your account to log in, of course.

Are you there ?Eyeart?

Yes, I do back up my Inbox. I have all the email. I just want to keep the email tabs available so I can refer to them quickly, and remember what my different clints need while I am working each day.

Hello there

Do you have Windows Explorer in your system, okay? This is where we go to be able to affect the window file by deleting a single pair or a file called the session.json

Please try to type this text when you open your Window Explorer.

%APPDATA%\Thunderbird\Profiles

Once you have arrived at this profile folder you will be given the opportunity to click on it twice. does it open now? okay. look for the session.json file here, try to delete it.

Restart some Software. Greetings Firefox volunteer

Hello there


Maintaining your cache comes across the other topics you are working on, these may also contain incorrect data, so you should delete them in a situation like you were, these also contain data. Whether it has to do with the cause what is bothering you.

Hello there

Okay, yes, that's fine, yes. in this case, let's clear the topic we're talking about session.json to start with. Are you ready okay.

Hello there

This will not be cleaned up after clearing it session.jason will come back into place after startup every time you do that. If there is something wrong with this regarding the tabs, for example, you can use this method.

I saw that you wrote multiple folders with these files in them? Do you have more folders with the exact contents so you have more of these same ones? Like duplicates.

That could be a reason why errors occur in your program?

I am so sorry, I can't understand what you are saying I should do.

Hello there

Erasing the file session.json . And restart your system again. Restart Thunderbird after that. The problem could be solved

Do you have duplicated maps in the system?

-session.json appears in several folders in my Profiles -delete it in all instances? -Will it disrupt any other TBird functions? -do you think it appears when a crash happens?

Hello there

Would you call it a crash for tabs and surrounding topics such as toolbars and frameworks? Replacing a push button is something else entirely. Have you now performed the action, were you successful and are your tabs working again?

Do you also use Gmail, for example because you also talked about email tabs? Or did you mean this one that you also named in Thunderbird?

My email tabs in Thunderbird are working--just sometimes they all go blank. I don't know what triggers this.

I am talking about the open mail tabs that show up in a row above the Inbox pane. Are we talking about the same thing?
