Hi to everyone,
I use Firefox 3.0.1 on Slackware Linux 12.1. The problem is that you can't install extensions. When I click on Add to Firefox button to install an extension, it doesn't open any page or any window. After a few minutes of waiting appears the classic Software Installation window, then I click on Install Now, it opens the Add-ons window in the Installation section. Below you see the name of the extension with the Waiting .... writing, and doesn't go on. I have already read this support page: http://support.mozilla.com/en-US/kb/...nstall+add-ons, but all the remedies described are useless. Of course I also tried to delete the .mozilla directory, but nothing to do. I tried the Windows version and it works correctly, actually if I have to install extensions, I install them with Firefox on Windows and then copy the extensions in the Linux profile. I read that the problem occurs only with Slackware, with other distros it works properly.
Do you have any idea to solve it?
Thank you,
Scorpion77

Reason: I solved the problem
Which Firefox package are you using (ie where did you get the package from)? I know Pat's SlackBuild modifies a few things, but I don't know if it touches the extensions (and I'm too lazy to download the patches to find out).

It's not a Firefox problem. Not only. I tried with Opera and Konqueror, but unsuccessfull. I read in another forum about the problem with tcp_window_scaling, but it is useless.
I tried Slax 6.0.7, which is a distro derivated from Slackware. With Slax all works perfectly, with any browser. So I can say it's a Slackware configuration problem, maybe the kernel configuration.
It will not be a kernel configuration problem. I believe you are the only one with this issue -- but I can't be sure (I know I haven't heard of it here before, but maybe I'm just not reading carefully enough). I am not currently using Firefox 3, but I use Opera and can install widgets just fine (though as far as I know there are no extensions to Opera). I know for sure that extensions work perfectly using Firefox 2. You could try installing extensions manually (see this thread -- you can use the same technique to install the extension locally to your user account by using the ~/.mozilla/firefox/profilename.default/extensions directory [change profilename to the randomly generated profile name]).
When did you install 12.1? Was it a fresh install or an upgrade? What have you installed (and how did you install it)? Have you made any customizations?
OK, I just installed Slackware 12.1 in a VM (excluding KDE), upgraded Firefox 2 (included) to Pat's Firefox 3 (in -current) using upgradepkg, and installed an extension successfully on the first try (using the generic-smp kernel in runlevel 4, but that should have no impact whatsoever on Firefox). You obviously have a problem with the Firefox package you are using (but you said you are having other browser problems as well) or your Slackware installation. It is most certainly not Slackware's fault and please do not blame the distro because of a configuration/installation error. I am willing to help you, but need more information about your Slackware installation and what you have done to it. You may be more successful with the advice of others since I am really just a n00b myself...but I'm here anyway.
I installed firefox 3.0.1 from the package at "www.getfirefox.com" moved it to /usr/lib/firefox-3.0.1 then set a smlink from firefox. That allowed me the option to change the link back to firefox-2.0.0.14 if I had problems. I installed several plugins and addons with no problems. Well, except for rhapsody's addon which I had to install manually from the xpi file. the helix (realplayer) addon installed automatically.
However I already explained that with Opera and Konquer I have the same problem. Even if I try to download an extension with the address it doesn't work:

The most important thing I did is trying with a fresh installation of Slackware 12.1. The problem persists.
So it's logical to think that should be a hardware compatibility problem, maybe with the network adapter integrated into my motherboard.
I can wget your linked file when passing the --no-check-certificate option, so it must be something with either your ethernet/wireless card drivers, your network setup or (doubtfully) your ISP. What is the output of the following commands (as root):
Code:
# ifconfig -a
# route -n
# lspci -vv
# lsmod
You may wish to try disabling ipv6 if you haven't already. You can blacklist it in /etc/modprobe.d/blacklist by adding the following line to the end of the file:
Code:
blacklist ipv6
and restarting. If you don't want to restart you can try removing the module manually by typing the following command (as root):
Code:
/sbin/modprobe -r ipv6
If that doesn't work try the simpler `rmmod ipv6`.
The kernel configuration problem is often a scapegoat. It seems to be the go-to 'answer' for any problems. It is probably NOT a kernel configuration issue; the only kernel issue I could see is if the wrong module is being loaded for your network card (easily fixable without recompiling the kernel) or if other, better, out-of-tree modules are available (like the iwl/ipw thing). Other than that, it is likely a configuration problem. It *could* be a kernel issue, but stop blaming it on that without any evidence for it whatsoever.
Also, Slax is VERY, VERY different from Slackware. Just because it is based on Slackware does not mean that any of its init scripts or configurations are even similar let alone identical.
scorpion77, do you run firefox as root or simple user ?
Maybe a permissions problem also
maybe worth a check ?
Code:
# check for dir perms != 0755
find /usr/lib/firefox/ -type d ! -perm 0755
#check for files not readable for group & others
find /usr/lib/firefox/ -type f ! -perm -044
What does make you think it is a kernel issue, do you have problem while browsing on linuxquestions.org for example ? Did you set a firewall ?

Did this get any further (your second wget command)? The 302 error is normal (it is a redirection). I get that too but then it downloads from the redirected URL. I get this:

If the command completes on your end, it is probably not a network issue (which I possibly incorrectly assumed before). If it doesn't, it may be.
I think I've found the origin of the problem: it's my wireless router, a D-Link DSL-G624T. As I've 2 computers, one in my room and one in the lounge, the only thing they share it's the router.
Here they are the outputs of the command you want to know (T3slider):
