Actually, it is not just a javascript problem. After Firefox unloads javascript, trying to access ANY site gives "File Not found". Ctrl-R and the file is found again (?!).

So probably this has nothing to do with javascript...

MMmmm... maybe this is why Firefox is loosing so badly against Chrome...

Did you try to disable all plugins or even move them to a different location, so Firefox won't find them?

No, only the addons. I'll try that.

Thanks, L.

I believe you meant Extensions.

The word Addons is actually a word (that Mozilla came up with as of Firefox 2.0/3.0) used to group together Extensions, Themes, Plugins, search engines, dictionaries, personas themes.

I don't know how the wording is used, sorry. But this is what I did: I removed the ~/.mozilla directory (hence cache, bookmarks, user installed "extensions", etc), and even running firefox as a fresh user and root, without making the thing any better. So the problem is user independent. Either a bug in Firefox, or a plugin (Iced-Tea?).

I am experimenting now disabling plugins. I disabled all but Iced-Tea and Flash. Next step will be to disable those. Next, I will change permissions of the plugin directory. If that doesn't help, then it has to be a bug in Firefox, at least in Fedora version, and the only solution would be to switch to another browser (no, reporting bug to Fedora wouldn't help since Red Hat bugzilla is nowadays essentially ignored and abandoned).

Thanks, L.

Ok, so I tried everything: I moved the ~/.mozilla and plugins dir: same problem. So it's firefox itself, no plugin/addon/cache to blame. No solution but leave Firefox, since this is happening since years now.

It looks like for some unknown reason it gives up searching for files on the internet, and assumes them as 'not found', sometimes a javascript, somethimes even the page itself, showing the 'not found' page, that is retrieved forcing with CNTRL-R.

A pity.

Thanks for the suggestion! It was good to discard plugin problem.

Cheers, L.
