Hi Jousma,

There are some known issues with recent versions of Firefox that automatically downloads the latest update when launching for the first time. Due to this change in functionality, launching the ThinApp also starts downloading the updates into sandbox that causes issues. The automatic download must be disabled to fix the issue.

We have a working version of Firefox 50.1, please download the ThinApp project folders here:

https://dl.dropboxusercontent.com/u/32979144/Mozilla_Firefox_50.1.zip

Please execute the build.bat to generate the bin folder with ThinApp executables. Also, make sure to delete any existing sandbox before testing it out.

There are some known issues with the other latest versions of Firefox. As a workaround/for time being, please use the 50.1 version that i shared.

Hey all,

Any development on this?
We are on the Firefox ESR releases, and this month marks the release of ESR 52.0, which now we're faced with the exact same issue.

Thank you.

You can have my project, please contact me privately.

It's nothing really exciting though, but maybe you can extract some details from it you can use.

Which version of Firefox is your project based on?

For me, 52.0.2 is the last version which works. 53.x doesn't work for me anymore, neither does beta (54.x). Oddly enough, a Nightly (55.x) works again. Maybe I'll try ESR too, see how that goes.

The symptoms are that the browser starts and shows its GUI. I can also open the preferences and all that, but closing tabs is flakey at best. Trying to load URLs doesn't work either. Closing the application sometimes works, usually I have to kill it. Weird stuff.

My captures are nothing exciting. Just a pre and post, some cleanup and ExternalDLLs=ucrtbase.dll in package.ini. And then it basically works. I do some other stuff too, but that's pretty much implementation details to make it usable in our corporate environment. They're not needed to get the base package to work: I include a set of mandatory settings, I add a VBS script to copy a default profile, install (and if required, remove) some standard extensions into that profile, and install a couple of certificates into the mozilla certificate store (which is also in that profile). I redirect the mozilla profile to the user home directory instead of leaving it take up space in the roaming profile.

[Edit]Sadly, ESR (52.1.1) doesn't work (anymore?) either.

Same problem. White Screen.

Hi Lakshman

I am also having the same issue with Firefox versions upwards of 49.0. I did disable automatic updates during installation but still got the error mentioned above.

Please could you re-provide your working Thinapp project folders?

Thanks

I've also moved on from this.

I suspect the issue might have something to do with how later versions of Firefox sandbox child processes. I recently got a Chrome Thinapp package working by disabling the sandbox with a launch parameter. The users receive an annoying message but at least the package is stable. I've not looked into whether this is possible with Firefox but I imagine it could be.

One of VMware's USPs of Thinapp is that it can supposedly virtualise any browser. So running into these issues without any vendor support is very disappointing.
