Thunderbird Portable

No folders or messages in TB Portable after power cut

Submitted by bobyorke on November 24, 2020 - 8:20pm


We just had a power cut and now my Thunderbird Portable (78.5.0, 32-bit) is not showing any mail accounts, folders, or messages. I've checked my data\profile folder and I believe my folder structure and mail is there. In my data folder I have found prefs.js, and it has lots of relevant stuff in it, including lots of "mail.account" entries.

Can anybody help me to restore my mail please? Just for info, I use MailStore Home from time to time, but sadly not frequently enough to simply restore everything. I'd be grateful for any suggestions ...

How to launch PA Thunderbird in "Offline Mode"? No Profile Manager possible

Submitted by pstein on November 18, 2020 - 10:22am

I read that I can launch "normal" Thunderbird with the "-p" parameter to get to the ProfileManager and switch there to "Offline Mode".

That in turn would open TB without access resp. message transfer connections in+outside.

Perfect. Thats exactly what I am searching (for temporary test purposes).

Unfortunately users cannot start PortableApps Thunderbird with the "-p" parameter..

ThunderbirdPortable.exe -p

So how else can I switch PortableApps Thunderbird to "Offline Mode"?

Thunderbird lost the profile (with temp workaround).

Starting today, it was impossible to get the profile up, I was presented with a blank page.

for the moment, my workaround was to install thunderbird on my PC, click on troubleshoot, then about:profiles, and finally create a new profile by pointing to my exiting one, copied from the portable installation, and making that the default. (the portable application has to be closed at that point, or it won't allow you access).

I couldn't direct to the portable profile from the portable app, it defaults to local appdata and won't redirect to the portable.

Thunderbird Apps denied by Gmail

Submitted by arielheryanto on October 12, 2020 - 9:53pm

From a couple of hours ago I can no longer access my office email account (Gmail-based). Google sent me a message, saying that it had blocked my access, because Google considered Thunderbird portable apps “doesn't meet our security standards”.

Having routinely relied on Thunderbird portable apps for the past 20 years, this news shocked me. Did anyone experience the same? Does anyone have any advice on how to meet this challenge? Thanks.
