Live Preview MultiBrowser does not launch browser on Linux

[jatin7gupta]

i did what ever was written in the text, but it didn't open in mozilla firefox beta version

Same here.
I am working with Firefox (34.0.5) on a Archlinux 64bits system up-to-date and on a KDE environment.
I do not get any error. The thunderbolt stay half-highlighted, see below:

I tried both with and without extensions. It does not work anyway.
I tried to get logs of error by starting it from shell, but it did not output anything.

@jatin7gupta, this is unfortunate it did not work for you. Are you on Linux? When you say it does not open the page, what exactly does not work? Is the browser not launched? Could you please provide the output you see in the Developer Tools console (use Debug -> Show developer tools to open it)?

[busykai]

@ekaradon, it would be very helpful to understand the cause if you provided the output on the developer console. I see you have debug.showErrorsInStatusBar on, could you please set it to false, reload Brackets and then use Debug -> Show developer tools to see the console and copy output from it?

NodeSocketTransport - send,,{"method":"Runtime.evaluate","params":{"expression":"_LD.hideHighlight()"},"id":1} /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87

The last line (NodeSocketTransport) is the only one relevant I think... not sure however.

@ekaradon, thank you for the log. I see. It sounds like your browser does not get started. Do you actually see the browser when you start Live Preview? If not, could you please run the following from the command line:

xdg-open http://google.com

Does this start a browser for you? If it does not, try following these instructions to set a default browser.

[ekaradon]

I see the browser, but nothing happens (no new tabs open, no new windows, nothing, ...). When I run your command, it opens google on firefox immediately.

[busykai]

@ekaradon, interesting. i'll have to look more into this. just to clarify: if you close the browser, restart Brackets, then click Live Preview icon (w/o the browser running), the browser gets started, does it?

[ekaradon]

@busykai, I just tried to launch Firefox by just clicking on Live Preview Icon and it did nothing, firefox is not getting launched by Live Preview Icon, even if Firefox is not running.

same here on Ubuntu 15.04

NodeSocketTransport - start /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87
NodeSocketTransport - send,,{"method":"Runtime.evaluate","params":{"expression":"_LD.hideHighlight()"},"id":1} /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87
NodeSocketTransport - send,,{"method":"Runtime.evaluate","params":{"expression":"_LD.highlightRule(\"[data-brackets-id='11']\")"},"id":2} /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87

---

when "livedev.multibrowser": true, i get "Live Preview: Connecting..." but nothing happens.

xdg-open http://google.com works, also Live Preview works fine when "livedev.multibrowser": false

yes, Ubuntu 15.04 (Vivid Vervet) http://cdimage.ubuntu.com/daily-live/current/

Same here, Ubuntu 14.04 with Firefox 34 as the default browser.

NodeSocketTransport - start                        /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87
...
NodeSocketTransport - send,,{"method":"Runtime.evaluate","params":{"expression":"_LD.hideHighlight()"},"id":1}                        /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87
NodeSocketTransport - send,,{"method":"Runtime.evaluate","params":{"expression":"_LD.highlightRule(\"[data-brackets-id='20']\")"},"id":2}                        /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87
NodeSocketTransport - send,,{"method":"Runtime.evaluate","params":{"expression":"_LD.highlightRule(\"[data-brackets-id='2']\")"},"id":3}                        /LiveDevelopment/MultiBrowserImpl/transports/NodeSocketTransport.js:87

xdg-open just works.

Got it reproduced on Ubuntu 14.04. Working on a fix.
