Will it get past the black screen now?

In that try setting enabled to false

Is there a file called jxbrowser something in your mods folder?

(Aside) Why, why do some mod devs use such un-descriptive mod ids and filenames? Try getting a fresh download of device mod apps, the jar may be corrupted.

I would suggest using Pastebin or GitHub's Gist(Gist accepts much larger files but requires a free GitHub account) for supplying logs.

Where are you downloading Minecraft from?

You should be good with that setup. If you go into your config folder do you see a file called splash.properties?

Unfortunately that's not something that can be pinned down to a specific mod as easily as a hard crash, most often I've seen this from people who don't quite understand how heavy Modded Minecraft can be on a PC. What kind of a setup/build do you have?

Have you tried removing Optifine?

That isn't showing anything indicative of a crash. When you say crash do you mean the launcher comes up saying the game crashed or does the game just freeze? If the launcher says the game crashed please read the logs section of my signature or the EAQ (pinned at the top of the subforum) and post the appropriate log.

Where is it showing 0 bytes? Are you sure your browser is finished downloading the whole file? What URL are you getting Forge from?

Install Game Stages

Judging from the GPU Driver this log is reporting, I'm not sure your PC is strong enough to handle modded.

This is explained in the logs section of my signature

I'm afraid there isn't anything helpful in this log, and unless Minecraft itself never opens there will always be a log of some kind in the logs folder. If you're running Forge there will be a debug.log in addition to the Vanilla latest.log

Please read the logs section of my signature and provide your debug.log

Please read the "Logs" section of my signature and provide your debug.log

Merged the two threads

Would you mind posting screenshots? I would assume this is more a browser issue than a Forge issue.

Please don't necro old threads, make your own.

This does not stop you from making an issue on their GitHub, which @Cadiboo linked for you.
