We have tried and dont'k work... we tried on 4 different pc and the problem is always the same and only with le the 60.5 version

We have resolved with this plugin "Disable Chunks" and regenerate the index msf file... so I think there is a problem with the last version because with 60.4 we have no problem

That is exactly contrary to expected behavior.

That add-on is creatred to work around a bug that was fixed in Version 60. So I think you best chime in and work out a real solution.

See https://bugzilla.mozilla.org/show_bug.cgi?id=1216951

I don't know... maybe with the 60.5 appeared again the same bug or a similar.

Do you think you could participate in the bug where this is under discussion.

I can't answer for you!

I'm unable to duplicate the problem with a large docx file (about 19M) attachment using >= tb 60.5. Need more details on what you were doing and what you see when the attachment fails to open. Also, need to know how tb is configured since there are lot of options that might affect the problem. Yes, if you could also post the information to the bug above it would be most helpful. Thanks!

Can you please try this version: https://queue.taskcluster.net/v1/task/AcRd5mSOROO3yWDvEyrmSQ/runs/0/artifacts/public/build/install/sea/target.installer.exe

This is a preview version of TB 60.5.1 for Windows where I have reverted a change made between TB 60.4 and TB 60.5. So this should re-establish the behaviour of TB 60.4. Let me know if you need a Mac version.

Windows may block the binary from installing in which case you need to accept the security exception. This is safe to install.

Please let us know the result as soon as possible.

gbianchin, One more request. Could you send me a sample email containing a problem attachment? I am still unable to duplicate the problem.

You can get my email address in my profile at this bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=1494764#c18

Hi Jorge K. , I tried this preview version and the probelm is resolved.

Thanks

The "fix" will ship in TB 60.5.1 later this week.

Thanks for testing. You can keep using this preview version which is a "real" ESR version, not a Daily as it claims.
