Did your DevMode Chrome extension stop working recently? Welcome to the party. The powers of divine wisdom on the Google Chrome team decided that NPAPI was a superannuated security hole and must die. The fact that they proposed no clear alternative solution has led many a plugin (Java, GWT DevMode, Linx Garmin Connect, VDPAU, GNOME Shell Integration, VMware VSphere Client, Nemid) to wither and die. But what about Flash!! Well, to keep important plugins from being impacted, they’ve been whitelisted, but for the rest of us who depend on the Chrome DevMode Plugin… too bad.
The timing is unfortunate, but the number of Linux users that require NPAPI plugins that aren’t Flash is just too small to justify this effort.
Retrograde GWT Plugin Install
You’ll need to revert to the less secure Chrome 34 build. Generally speaking, this is a bad idea, so be careful with this. Don’t do things requiring security on it. Sadly, the Chrome team has left us little choice, while also saying you shouldn’t do the above .
- Download and install the Chrome 34 Portable Installer (has no updater)
- Reenable drag and drop install of disabled .crx extensions
- Install GWT Chrome extension from the Chrome Web Store
Hopefully that works for you. Now you can continue developing GWT until Chrome adds more road blocks, but you should really consider moving to SuperDevMode. If you’re keen to help, please contribute to the SDBG Eclipse Dev Mode replacement project.
