I'm on Ubuntu 16.04, Chrome Version 62.0.3202.94 (Official Build) (64-bit), Thunderbird 52.4.0 (64-bit).
I'm having a problem with Chrome that only happens when I click on a link within Thunderbird. If the browser is already started up, everything works fine. If the browser is not already running, it appears that Chrome is opening - the Chrome icon lights up on the launcher - but the page never shows up. This is what I've tested so far:
- Disabled all plugins, extensions, etc. in both Thunderbird and Chrome.
- Links open fine from other apps - LibreOffice docs, Cherry Tree, etc.
- If I set Firefox as the default browser, that works fine whether or not Firefox is running when I click the link.
- I have two different profiles in Thunderbird; the problem is the same regardless of which profile I load at startup.
Please note that this is not a problem with the default/preferred browser; it has only to do with whether Chrome is already open or not when a link is clicked in Thunderbird.
Even though this is not actually a preferred browser issue, I tried all the various suggestions I could find related to problems with the correct browser launching for Thunderbird links; none of them made any difference. In all cases, the settings worked as they should if Chrome was already open when I clicked the link, and didn't work if it wasn't open:
- Changing network.protocol-handler.warn-external.http & .https to true, and then manually choosing Chrome when prompted to pick app to open link
- adding a user.js file specifying the browser to use
- Specifying Chrome as the app for http and https in Incoming Attachments
I'm at a loss. I would be very grateful if anyone has any suggestions for how to troubleshoot this further.
