WebUI issue with firefox 48 and Electrolysis

[Guigui]

Hi everybody,

A few month ago, I had a try of firefox developper edition to test Electrolysis, which seem, to me, to improve utilisation of the browser. Everything was working fine on every website, on other WebUI I was using (nas, etc), but not on proxmox: mouse clicks was not working on it, but keyboard was ok (I mean on the entire WebUI, not only on novnc console).

Went back to stable firefox version to get it working again, but now Firefox 48 is out, Electrolysis is enabled by default for 1% of users, and will be in next version for 100% users, and the problem remains !

You can see following links on how to force enabling Electrolysis to have a try.

mhmm, what exactly is not working? does the javascript console print any error message?
I installed firefox 48 here, enforced e10s and had no problem using the webinterface (i could navigate, open the console, etc.)

 

[Guigui]

Thanks for your reply.

Every left click on the mouse are not working. Left click selects each button or objects on the UI, but doesn't submit them. I have to use the left click to select the button, and enter on the keyboard to validate it.

Example: the login form. If I left click on "login" button, it selects the button "login", but doesn't submit the form. If I then press enter on the keyboard, it submits the form.
Same with "create vm", "create ct", "logout", "datacenter", well everything on the page...

Same thing using private navigation.

You installed firefox 48 and enforce e10s, on what OS ? Of course you have then restarted firefox ?

Thanks !

I tried to manually disable all extensions, restart in safe mode, or restart after deleted pref.js, same problem, and nothing on console, but this:

15:02:55,136 unreachable code after return statement1ext-all.js:22:344134

 

[dcsapak]

yes i restarted after setting the force enable option.

i tested on debian jessie, ubuntu 16.04 and windows 10 without addons/extensions

no problems on either os...

"the unreachable code after return statement" is more a warning than an error (it also shows here, but does not hinder the behaviour)

 

[Guigui]

That's what I was thinking about, just a warning and not an error.

Well, I continue my tests, using a guest blank session on ubuntu, enabling browser.tabs.remote.autostart in about:config, disabling all extensions, restarted browser, checked in about:support line "Multiprocessus windows" is enabled, and still the same problem.

You said you have tested on ubuntu 16.04, but how did you install firefox 48 ? I tried with this ppa:
https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/ppa

Have you tried this on a proxmox server with a non secured certificate ?

Thank you!

Guillaume

 

[dcsapak]

You said you have tested on ubuntu 16.04, but how did you install firefox 48

I downloaded it from https://www.mozilla.org/en-US/firefox/new/ and executed it

Have you tried this on a proxmox server with a non secured certificate ?

the certificate is untrusted and self-signed, so i had to add a security exception first

 

[Guigui]

Tried on Ubuntu to download the bz2 file of firefox 48, executed it in guest session, same problem... on and amd64 system, and with an untrusted and self signed certificate...

 

[Guigui]

It works on a windows 7 32bits or a windows 2008 64bits...

I will have a try this evening on an other ubuntu 16.04 at home...

 

[Guigui]

Hi,
Haven't try @home for now, but I tried an extjs 6 demo website, I got the same problem, can't click on anything, working without e10s...
http://examples.sencha.com/extjs/6.0.0/examples/admin-dashboard/#dashboard

So it seams to be a problem between firefox 48 e10s and extjs 6, but I'd like to successfully reproduced this somewhere else...

I'll keep you informed.

 

[Guigui]

Well, can't reproduce this bug between extjs and e10s somewhere else... That makes me crazy...

This is the same problem I reported after the 4.2 was announced (in anouncment thread). However I'm using Windows.

P.S. The only message in console is "unreachable code after return statement[Learn More]ext-all.js:22:344134"

 

[penetal]

I have the same problem as described by Guigui, I am currenty on FF49 under Ubuntu 16.04.
I doubt this will help, but I noticed the syntax highlighting in FF stopped working in the ext-all.js file, so I took a little screenie just in case http://i.imgur.com/mlrGBxi.png

Here is the exact message from the JS error http://i.imgur.com/4ocDcMd.png

 

[fabian]

I can't reproduce this here either (using FF49 from Ubuntu, with about:support showing "Enabled by default" for "Multiprocess Windows"). The JS console does display the warning about "unreachable code", but the GUI works just fine nevertheless

 

[chelmzy]

I'm also having the same issue (FF49 in Fedora 24). It's odd because my Edgerouter Lite WebGUI was also broken by this update. Using a different browser for now.

I'm also having this issue on FF 51 on Ubuntu (essentially no clicks work anywhere in the interface). Anyone had any luck resolving this?

 

[Blinkiz]

Same problem for me.
Clean Firefox v50 on Ubuntu 16.04.

1. Start a clean Firefox by creating a new profile, run "firefox --ProfileManager".
   
2. about:support page shows that "Multiprocess Windows" is disabled because of not compatible addons. Proxmox web interface works.
3. Disable "Ubuntu Modifications" extension on the page "about:addons" and then restart firefox.
4. about:support page shows that "Multiprocess Windows" is enabled. Proxmox web interface does not work.

Just out of curiosity, do you have a touchscreen, Blinkinz?

I do not use a touchscreen in this case.
Am having same problem on Sencha ExtJS 6.2.0 demo page.

I am using a touch screen laptop as well. I am using Firefox 50.02. I registered to inform the community that I am not able to use the Proxmox interface using Firefox. I can use epiphany (gnome web) somewhat. I am not able to click on any of the elements. I am using Fedora 24 and 25.
