Hello Radmir,

Please have a look at this article first and make sure to have read it completely. I’m not familiar with Waterfox, but perhaps choosing Waterfox as the default browser - possibly after choosing another browser first - may be the solution.

Does this help?

Hello, Tonnes,

It seems it is the internal problem of EarlyBird, the link in mail message doesn't open regardless witch browser set as default: Warefox v 50.1, IE v 11.0.38

May be just reinstall it?

Yours, Radmir

You can safely reinstall it, but I doubt if it will fix anything.

- Did you read all instructions in the article and check that either http or https is listed and set in the list shown in Options > Attachments > Incoming (tab)? If any of them are available, set it to "Always ask" and see if it really asks when clicking a link, then choose the action and make it persistent. You can also choose to delete both entries. - Additionally, does one of these protocols work and the other does not, or neither of them? And does that correspond to only one of them being listed in that dialog?

For what it’s worth: when testing on Windows 7 using Earlybird here, I only see https listed and Use Firefox is chosen in the drop-down, but both http and httpd work. That would indicate TB/Earlybird handles these links as registered in the OS, which it should. Funny detail: that happens on a system that never had full Thunderbird release versions (.exe) installed, only zipped Earlybird builds.

- Are there any other mail apps that do open the links? If not, make sure you are able to make such a change for the Windows account.

Als make sure to check the network.protocol-handler.external-default preference as well - it should be set to true (default).

If nothing helps, please have a look at this question and report back.

The only incoming attachment is Foxit Reader pdf document, Action is always ask. No http, https, httpd exists.

May just just throw away EarlyBird and install ThunderBird? I installed WaterFox and EarlyBird cause the claimed as 64 bit apps. I also tried to set Default Browser through Control Panel > Default Programs - nothing changed, after restart...

Yours, Radmir

Now we may be getting somewhere. Waterfox is 64 bit allright, but so is Firefox nowadays, as well as 32 bit. Both Thunderbird and Earlybird (=aurora) however do not offer 64 bit builds for Windows (yet), only for Linux, so that would be to no avail. Nightly builds (so-called "Daily" releases, from the central/development repository and currently named version 53) however do exist for 64 bit Windows, but they can be very unstable and you can expect things like this to happen. Hence, did you install an Earlybird build from here, or a real central build from here?

If you are not involved in development or testing, you would be better off by installing a regular release version from here). 64 Bit builds should not offer any speed improvement anyway - see here for more info about 64 bit builds, and note the bugs and issues. You could of course install a release version, see if that behaves correctly, uininstall it, and then install a real Earlybird version, but that would still be 32 bit. (Like I wrote above, Earlybird builds should use the OS settings for opening http(s) links without ever having a release build installed.) You could then remove the Earlybird version and install a central build afterwards, just to see when things go wrong.

Note that by default, all versions will use the same profile. In case all versions fail for opening the links, you could just create a new profile and see how that goes, or you can do so first for the version currently installed without experimenting with installs.

Thanks a lot, I uninstalled Earlybird and install it again. You were right, nothing changed. I removed it again and installed simple thunderbolt. Last works wonderful, and it cope's without backing up profile.

Last year I exploit Windows 10 and EarlyBird worked well, but after changing it on Windows 7, links stopped working...

But I'm closing this question, and never will return, (some problems must leaved unsolved).

Your, Radmir

Glad it worked and you’re welcome, though I cannot explain why links would not work on Windows 7 only. Could you mark one of the replies above as solution?
