Affected versions

• 85.0a1
• 84.0b4

Affected platforms

• Windows 10x64
• Ubuntu 20.04x64

Steps to reproduce

1. Launch FF.
2. Go to about:config, disable print.tab_modal.enabled preff.
3. Open system modal , go to Preferences.
4. Go to Paper Tab, notice Scale percentage has max limit of 400%.
5. Go to about:config, re-activate the print.tab_modal.enabled preff.
6. Open the new Print modal.
7. Go to More Settings.
8. Go to scale, Custom and input 400.

Expected result

• User is able to select 400% scale value, just as in the system modal.

Actual result

• Error is displayed stating that user can set up a max percentage of 200%.

Suggested Severity

• Seeing as how this issue can be bypassed by simply using the old modal, I would S4 this issue.

Regression range

• This issue is not a regression.

Additional notes

• In order to assure a good UX accross platforms and menus, the default max levels from both modals should coincide.
• This issue occurs for macOS as well, but the system modal is different for this platform.

The system dialog on macOS doesn't seem to impose a limit; I can specify 1% or 10000% and it doesn't object.

I do think we should at least allow up to 400% in the new UI, for better consistency (and it's not such a huge value that it's ridiculous to request it).

This restriction is in the frontend code

(Moving bugs to 86, part 1.)

Moving things to 88, cause we're mostly on Proton these days…
