Weird Firefox add-ons issue [SOLVED]

Hi all,

I have a very strange issue with Firefox 29. Whenever i try and add any extensions or themes etc through the menu i get this:
http://i292.photobucket.com/albums/mm15 … refox1.png

Ok i thought to myself, to the website!
nope. http://i292.photobucket.com/albums/mm15 … refox2.png

Ok then! must be my computer somehow, better try this in Chromium!
http://i292.photobucket.com/albums/mm15 … refox3.png
Works fine.

Seriously im stuck. I've tried reinstalling, checking dependencies etc and i cannot see anything wrong. Everything else works as it should. I can search the web and watch video's on YT etc.

Any help is appreciated,

Kind regards, Steve

Re: Weird Firefox add-ons issue [SOLVED]

Whilst I doubt this is the case, are you actually using any add-ons right now?

I've just had a look for myself, and the pages look fine.

My assumption is that all was fine with Firefox 28?

Hi Patrick.

I tried this but it looks like im missing the 'xpinstall.enabled' part?
See picture:

That is literally all the options i have. So im unable to 'enable' or 'disable' it

Re: Weird Firefox add-ons issue [SOLVED]

It's working fine at my end. I don't have the xpinstall.enabled key either. The whitelist keys are empty for me but I doubt that's the issue.

If you want to start over again from scratch, deleting the profile folder might help.

Have you taken a look at the download problesm in the link Calistoga posted earlier?

Just closed Firefox, ran firefox -p, Deleted the old profile. Made a new one. Started Firefox up, STILL the same problem. It seems to be ONLY websites associated with Firefox.

It's actually super frustrating that i cant figure this out. IT WORKS IN CHROME FOR GOD SAKE!

sigh.

Any ideas now guys?

Re: Weird Firefox add-ons issue [SOLVED]

Such a behaviour is usually the result of using an addon like RequestPolicy, but you aren't using any addon. Are you using any filtering proxy (privoxy, for e.g.) or firewall that might be causing this issue? Of course it doesn't explain why chromium displays the page fine.

One thing you can do is to give one of the official Firefox binaries a try, and try it with a fresh profile:

https://www.mozilla.org/en-US/firefox/all/

Re: Weird Firefox add-ons issue [SOLVED]

Have you tried opening the page's source and viewing the the css files? Do they open?

Re: Weird Firefox add-ons issue [SOLVED]

Right-click on a page and choose "View Page Source", then search for a .css file and click it (it should be a hyperlink).

Alternatively, press F12 to bring up the developer console, then click the Style Editor tab.

The first method is probably the best one, the second may hide malformed documents, and that's what I'm looking for.

When i click the HyperLink i get this:

Re: Weird Firefox add-ons issue [SOLVED]

I think I've figured it out. Rather embarrassingly I hadn't noticed that my date was 1 day behind (10/05)
I just changed it to the 11th and rebooted. The page now loads.

So simple i never even looked at it was right there in front of me the whole time. Thank you all for taking the time to reply to me and help diagnose the issue.
WorMzy: Without your help i wouldn't of got the hint to my problem, thank you.

Now excuse me while I go sit in the corner with the cone of shame on my head.

Re: Weird Firefox add-ons issue [SOLVED]

Glad you got it sorted. It's strange that Chromium doesn't care that the certificate was *seemingly* created in the future. Perhaps it has additional checks to confirm the validity of a certificate. Ah well.
