OlgaTPark/tenfourfox#14 — Add a Keyboard Shortcut to Reader Mode

[OlgaTPark]

Here are the changes discussed in OlgaTPark#14 needed to add a keyboard shortcut to Reader Mode (the patches are based on PowerPC TenFourFox FPR6 because I tested them in OlgaFox FPR6).
This commit doesn't include M1438308 which changes the shortcut on Windows to F9.
I also didn't included M1480415 which concerns a Windows screen reader that cannot "see" the reader button in the toolbar (but I doesn't expect a better situation on Mac OS X).

If you want, I can also add the changes for the pdfjs.display.use_document_fonts=true setting to this pull request.

Concerning localizations, two files are affected:

 <!ENTITY fxaUnverified.label "Verify Your Account">

(which ends up in {TenFourFox.app/Content/Resources}/browser/chrome/en-US/locale/browser/browser.dtd).
Here, the change is the same for every locale (checked in Mozilla XPI_s).

(which ends up in {TenFourFox.app/Content/Resources}/browser/chrome/en-US/locale/browser/browser.properties).

I extracted the translated strings for every locale supported by TenFourFox from http://ftp.mozilla.org/pub/firefox/releases/60.0/mac/xpi/:

Locale	Translated string
de	reader-mode-button.tooltip=Leseansicht umschalten (%S)
en-US	reader-mode-button.tooltip=Toggle reader view (%S)
es-ES	reader-mode-button.tooltip=Cambiar vista de lectura (%S)
fi	reader-mode-button.tooltip=Näytä/piilota lukunäkymä (%S)
fr	reader-mode-button.tooltip=Activer/Désactiver le mode lecture (%S)
it	reader-mode-button.tooltip = Attiva/disattiva Modalità lettura (%S)
ko	reader-mode-button.tooltip=읽기 모드 토글(%S)
pl	reader-mode-button.tooltip=Przełącz poprawianie czytelności (%S)
ru	reader-mode-button.tooltip=Включить/отключить Вид для чтения (%S)
sv-SE	reader-mode-button.tooltip=Växla läsvy (%S)
tr	reader-mode-button.tooltip=Okuyucu görünümünü aç/kapat (%S)
zh-CN	reader-mode-button.tooltip=切换阅读器视图 (%S)

And for my forgiveness, I can already translate the strings from #328 (comment) in French:

• "Domain" => "Domaine"
  • I greped it in the localizations to see if it's already somewhere else and I've found:
    • TenFourFox.app/Contents/Resources/chrome/fr/locale/fr/cookie/cookieAcceptDialog.properties: domainColon=Domaine :
    • TenFourFox.app/Contents/Resources/browser/chrome/fr/locale/fr/devtools/client/netmonitor.dtd: <!ENTITY netmonitorUI.toolbar.domain "Domaine">
    • TenFourFox.app/Contents/Resources/browser/chrome/fr/locale/browser/preferences/cookies.dtd: <!ENTITY props.domain.label "Hôte :"> (This variant has a « Hostname » meaning)
• "Configure Site Preferences" => "Configurer les préférences du site"
• "Always Open in Reader View" => "Toujours ouvrir en mode lecture"

Thanks for doing this. I was expecting a menu item, though (or at least to unhide the existing one). I guess I don't mind this being attached to the bar icon too, but it seems like it should be in both places and the string changed to "Enter Reader View" (capitalized).

Adding @chris-chtrusch about the locale change.

[chris-chtrusch]

For which FPR version is this planned?

[classilla]

Well, I guess that's a good question. I'd hate to ship locale updates back to back and even though this is a really low risk change I'd prefer not to ship a new feature without a beta. The two options are to hold the Enable JavaScript feature over for the next release, or to hold this one for another locale change. @NapalmSauce , do you have any strong feelings here?

[NapalmSauce]

Well, I have my builds, so I don't mind if you hold the JS toggle for the next release, really. Thanks again!

[chris-chtrusch]

I have no problem making back-to-back langpack installers. Do you think people will be confused if they have to download yet another installer that only lasts one version?

The only thing I don't really want to do is to make the langpacks 'blindly', i.e. without an English (beta) version of the browser that actually has the new items working.

[classilla]

@chris-chtrusch I agree with that too (that's why we have betas). @NapalmSauce , thank you for being flexible! Rather than do a full backout I'll just neuter the Enable JavaScript option and add it back for FPR29b1. I will merge this PR then as well with the requested change(s).
