I'm on linux system (OpenSUSE 12.1) running firefox 17 trying to get a java web site to work for me. I believe that I use a plugin to achieve this so on searching for a plugin I get offered Java Console 5.0.12 I accept the terms and conditions and firefox starts to download but immediately reports that there was an error downloading try again. Not sure how to get this working as it's been like this for days.

Am I trying to install the wrong version? It's the one Firefox offers me.

just installed FF 18.0 on Linux (Centos 5.8) where 17.0.1 has been running fine.

I always install in a local (to my login) directory, and have a desktop launcher to start it. I download each .tar.bz2 FF package to a subdir, where I unpack it, overwriting whatever was already in the firefox directory in that location.

doing that, I get the error above. so I renamed the directory and did a fresh extraction into the firefox directory that tar creates when unpacking the archive. SAME PROBLEM.

moving that directory aside and re-extracting the 17.0.1 archive yields a working Firefox.

What can I do to solve this problem?

the troubleshooting info below came from FF 17.0.1, since FF18.0 doesn't work.

I've gotten the font size of the tabs and menu bars and buttons too large, in both firefox and thunderbird, and can't figure how I did it or how to shrink them to the right size. This is not the websites I'm talkling about, but how the program displays are sized. I've gone over and over the menus and options and can't find the adjustments.

Previously this same question has been answered and closed, but not resolved and it states over 600 people have the same problem. Firefox will not shut down, and needs to be shut down through task box, surely this is not a real solution.

I have gone through all the processes stated https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_firefox-hangs-when-you-quit-it but they don't seem to work. I have Firefox 17.0.1 with windows 7. This proves a huge security issue on a shared computer when the history is set to be cleared each time the browser is closed - when it fact nothing is being cleared.

Mozilla can you actually please provide a reason why this is happening and fix it?

In the last few weeks, a lot of my Firefox windows hang for long periods of time - a minute or more. Today it got much worse, where it would hang for ever (defined as many minutes until I got tired of waiting and killed it).

After trying many things - It appears to be Javascript related. If I disable javascript - all the sites I go to first complain that javascript is not enabled butthen offer me a javascript free version. I have no hangs with java script disabled. a few sites just won't work with out it - but still no hang. As soon as I re-enable javascript - all my windows hang. I have tried only having a couple tabs open but still they hang. This happens with google mail and Yahoo mail as my base two. But if I open several other windows instead, they hang as well.

I tried downgrading to Firefox 17 - no help there.

I tried updating flash, I tried downgrading flash. No difference.

I have run out of ideas on what to do here.

When I close out of Firefox 17 it always restores my previous session when I open the browser back up, no matter how many tabs I had open before I close. It does not take me to my homepage setting, just reloads the previous session before close. All the time. How do I fix this issue?

Problem started when I had a few windows open and I closed them and tried to open firefox in quick succession.

When I used to close firefox, it used to save my 800 tabs automatically, no message popped up when I closed, and when I opened firefox up again, all my tabs were there.

Now, when I close firefox, it warns me that I am closing 800 tabs. It gives me no option to save. When I open firefox back up, it doesn't let me "restore previous session," it is greyed out. However, I can go "recently closed windows" and use that to restore my session. Restarting firefox is also really slow now (I am not sure if it is closing or opening, but I suspect it is closing).

I have "show my windows and tabs from the last time" selected in options. I am not having it clear history on close. I set showQuitWarning, all options with "warnOn..." in them to true (only changed warnOnRestart), and privacy.clearOnShutdown.sessions to false.

I am not shutting down my computer until this is solved. These 800 tabs are important (will be about 500 after I finish culling, was 1365 yesterday).

Unable to connect

         Firefox can't establish a connection to the server at www.google.com.
       

 The site could be temporarily unavailable or too busy. Try again in a few
   moments.
 If you are unable to load any pages, check your computer's network
   connection.
 If your computer or network is protected by a firewall or proxy, make sure
   that Firefox is permitted to access the Web.

Yahoo took over my Firefox- help!

About two weeks ago for some unknown reason Yahool basically took over my Firefox. All of a sudden it was my preferred search engine, Yahoo! TAB shows up in my toolbar (can't remove it) and in general it's been doing some goofy things. I swear I didn't give out any permission for this, but I hate it and it's driving me crazy (actually temp swithched back to Explorer). Tried uninstall and reinstall, but it's still there. Read somewhere that Yahoo hides it's files in hard to figure out places so it can't be deleted. Can anybody help me figure out how to get rid of Yahoo? (ESPECIALLY THE TOOLBAR TAB AT THE TOP) Many thanks!

I've been using a custom font (DejaVu) with unchecked "allow sites to use their own fonts" since a long time. But now some sites came with this new idea of icon fonts that look completely broken (a weird box with crazy stuff inside) until I globally check "allow sites to use their own fonts". Is there any way to configure different fonts per site? Specifically I would like to keep my all time configuration except for these specific sites which should be loading their beloved fonts.

Several versions of Firefox are incorrectly reporting the certificate as being untrusted for the web site https://commportal.telehop.com (A Canadian VOIP and cable company) I have tested this on several different netwokrs and all in Canada, Ontario report "the connections is untrusted."

How can this happen ? I have tested version 13, 17 and the latest as of "Mach-21-2013"

I used the following site to confirm. http://www.networking4all.com/en/support/tools/site+check/ as well as http://www.digicert.com/help/index.htm?host=www.proxify.com&order_id=&x=38&y=14. The latter shows the following result

"SSL Certificate is not trusted

The certificate is not signed by a trusted authority (checking against Mozilla's root store). If you bought the certificate from a trusted authority, you probably just need to install one or more Intermediate certificates. Contact your certificate provider for assistance doing this for your server platform."

How could this store be incorrec for only Firefox and not Safari or Internet explorer?

When i open a new tab, it shows the history in it in multiple small windows. How can i manage it to show a blank page when i open a new tab. in addition, i want to keep the history, and see it when i want, not when i don't want!

Whenever I click a link, it opens in a new tab. This just started almost a week ago, but I didn't change any settings or click anything--it just started doing it by itself. It is extremely irritating, because it just increases the number of tabs I have.

Not all images are being displayed but they do appear with other browsers. This just started happening today. I've tried dropping cookies. Resetting cache. Rebooting. Even uninstalling and reinstalling but the problem still is there.

I'm running on Vista.

When I start up Firefox, my Facebook Messenger tab appears but it says "Firefox is unable to connect with Facebook Messenger right now." Two buttons appear, one showing "Try Again" and the other showing "Close This Sidebar" When I press "Try Again", it nothing happens. It will not connect. I have tried restarting Firefox and my computer as well as uninstalling and reinstalling Firefox. I cannot get this functionality to work.

i use firefox for samsung galaxy s3 and instead of downloading videos it starts to play them which is very anoyin and disturbing when i want to download them. please help me with this.
