Feature: table export: implement support for Firefox export as .xlsx .ods .csv .pdf

[foss-]

Describe the bug
Currently export in Chromium browsers supports .xlsx .ods .bin .csv .pdf
while Firefox only supports export as .bin

Expected behavior
Would be great if Firefox could support export to those common formats as well.

Browser (please complete the following information):

• OS: macOS 11.2.3
• Browser: Firefox 89.0a1 (2021-04-01) (64-Bit)

Hi,
Are you testing this on CryptPad.fr or your own instance?

[foss-]

Sorry my bad. This is instance specific and I will follow up with the responsible person. Excuse the noise.

I see the exact same thing on cryptpad.fr...

[ansuz]

@meaz: this feature depends on some fairly new APIs being enabled in client browsers. It may break under extreme conditions: such as when using an old version of Firefox (ESR) or Edge/IE, if you've made modifications to your about:config, or if you're running extensions which actively interfere with standard behaviour.

[meaz]

thanks ansuz

@ansuz I've tried with firefox 87, with no plugin and no change in about:config.
It is working fine on cryptpad.fr but not on cryptpad.disroot.org. CHromium works on both.
Could it be a server issue? And if yes, what should we be looking for?

[ansuz]

@meaz the most likely explanation is that you're not setting the headers that enable SharedArrayBuffer.

[meaz]

@ansuz it is set. I forgot to tell you that I have this error with firefox only, not chromium...

There are around 700 third-party instances, so ss a rule we can't realistically spend much time helping to configure them. That said, here's a quick check that suggests the headers aren't being set as you believe.

We've been developing a "checkup" page (/checkup/) that automatically runs some diagnostics on instances to detect these common errors. I'll try to integrate this test into that page before our next release.
