My Firefox keeps crashing. I've uninstalled it, reinstalled it, run it in safe mode, and nothing seems to prevent the crashing. I completely deleted all of the old Firefox files before reinstalling it, but even the fresh clean version keeps crashing. The crashes happen almost immediately. I open the browser, try to load a site, and the browser crashes within a few seconds.

I have my system set to minimise windows by double-tapping/clicking them on the title bar. It works for most of windows (iTunes being exception). It's a system preference thingy, so it should work across all the board. After the recent update to 21.0, my Firefox is unable to minimise by double-tapping on the title bar anymore. Is there anyway to fix this issue, or will this be solved in the next update?

Ever since I upgraded to Firefox 21, Firefox stopped asking me what to do with MP3 or video files. The default action now is to play them in Firefox. I've previously set Firefox to ask what to do with these files. When I go to Applications settings, the setting I made is still there but gets ignored.

I know that I could set media.windows-media-foundation.enabled to false to disable playback for these type of files completely. That's not what I want. I want to be able to play these files in HTML5 audio and video tags.

I have the same problem as https://support.mozilla.org/en-US/questions/881844 but with fx 21.

Firefox 21 on Ubuntu 13.04 stops loading pages after a while, ranging from less than an hour to a day, of regular browsing. It gets stuck on "looked up whatever.com" or "connecting to..." message. Restarting the browser makes it work for another period.

Changing network.http.max-connections did not help, clearing various history items (cookies, cache, ..., or everything except saved passwords) did not help.

I now disabled ipv6 https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can?#w_ipv6 and prefetching but the fact that the problem occurs after several hours makes it hard to test.

Greetings! I've downloaded a program and here was some virus, now i alway have this page http://searchiu.com/?affil=141 as a start page and i'm afraid of my security. Can you help to remove this virus and get back my start page? Thanks you!

Please provide some specific direction for this error message. This message happens each time I attempt to launch Firefox. If I click restore, it will load Firefox. But to do this each time is very bothersome.

Ever since February (some kind of update happened), Firefox has basically died on my computer. I open it and only for a few moments does it work with any kind of speed, then it literally dies to a snails pace. It takes minutes even to scroll a screen or open a menu screen. And that's just being on the Mozilla site. Forget about trying to open any other significant websites. I have tried everything from reinstalling, resetting and disability plug-ins. I will say that the Firefox Icon at the bottom of my screen shows a security shield on it, which didn't use to be there. I really need help. I've been forced to use Chrome, which did work fine, but I can't stand it. SAVE ME PLEASE!!!!

I have a dell inspirion mini 10, and i just recently got all the settings rebooted and reinstalled xp. All i have right now is internet explorer, and the first thing i did on the internet was attempt to install firefox. The first two times my modem fell off, so im not sure if that has anything to do with the problem. Bu t now everytime i try to install firefox it stops at 99%, and doesnt finish. Ive had the same problem with downloading adobe flash player and ccleaner, but i was successful in downloading vlc media player through ninite to test things out, and and old, archive version of adobe flash player. Practically nothing is on this comp, so i dont think theres a problem with sercurity firewall or not, and im afraid it just might be the computer is on its way out, please help.

Is there any way to start Firefox for Android in private browsing mode by default ?

I have tried searching here (didn't find a solution) and also tried changing the setting in about:config but that didn't work.

It would also be nice to set FF for Android to clear private data on exit/quit.

Solutions to either problem would be greatly appreciated.

I have problem loading Java related websites after an upgrade to the latest version of Firefox 17.0

Some pages, keep asking me to enable "Javascript". Under preferences, "Enabled Javascript" is already being checked, yet the websites still will not load.

Java is already updated.

I do not have this issues before the upgrade, and all along it is working fine.

Hello everyone, This is driving me crazy! I've been trying to fix this a couple of times but no luck.

I'm trying to watch youtube videos on firefox and so whenever i try to enable flash player it just freezes my firefox...

I've uninstalled flash, installed latest/oldest, uninstalled firefox, restarted my comp, deleted the directory, disabled hardware acceleration, cleared cache and no luck...

When I use html 5 it doesn't freeze though I don't want to use it because it doesn't have 240p quality option.

Sometimes when flash player is enabled it doesn't freeze instantly only when i enable html5, play a video, close it then enable flash player addon then load the video which doesn't freeze until 3 mintues then freezes completely.

Ideas? Thank you.

So the latest version of Firefox 19 comes with a built in PDF viewer.

The problem that I found is that this viewer at its present time does NOT show fillable fields ina PDF, or let the user type into these fillable fields, or show the electronic print and instructions buttons we place at the top of most of our PDF "forms".

Ex: http://www.tmcc.edu/financialaid/downloads/forms/1213/FINAConsortiumAgree1213.pdf

This form should show buttons at the top and let a user fill it out. It does with the Reader plugin. In FF 19's built in PDF viewer I cant seem to do anything.

We presently make all our PDF forms fillable, so if this is an issue, hopefully a fix or update can be found.

So, after updating to Adobe Flash 11.7...I can no longer watch a single video anywhere on the web without the sound randomly cutting out. Flash does not crash, it just stops playing the sound and keeps playing the video. I can rewind the video to a time before it cut out but then it cuts out again RIGHT as I rewind to a new point in the video. Where as before in the location I rewound to, it did not have the sound cut out before when I first watched up to and past that point. I have no idea what has caused this (except or maybe Adobe screwed something up).

Does anyone else have this issue? And what have you done to solve it (if you have)? Also, if this a Firefox only issue? Or is it everyone Web browser?

Thanks for any help given.

Running Windows 8, Firefox 18.0.1, plugin Shockwave Flash 11.5.502.146 (current version, according to Firefox plugin check).

Firefox freezes every time when loading a page with Flash content when the Flash plugin is enabled. Firefox does not freeze when the Flash plugin is disabled. Repeatable, tested and confirmed multiple times - freezes consistently with Flash plugin enabled, loads pages perfectly when Flash plugin is disabled (though without Flash content).

When in this frozen state, Firefox is completely unresponsive - displays a blank page, can't type anything, can't click on or move/minimize the window. Must be force-quit via task manager.

Other browsers (e.g. Chrome) do not have this issue with Flash. Have noticed several similar problems reported with Firefox and Flash, but the only solution I have seen offered is to downgrade Flash (and introduce potential security issues). Surely there must be a better option? This is a massive issue for me - Firefox is my preferred browser but I cannot use it while it has this allergic reaction to the Flash plugin.

All of our PDF file build in Abode Indesign CS4. If any pdf open with mozilla, will come error message will be come on top of page. why this error coming every time and every pdf files.

I keep clicking no thanks and every time I start Firefox it pops up again. It is starting to irritate me enough that I will uninstall Firefox if I can't get it to stop - Why have a no thanks button if you are going to constantly irritate people by asking every time you open the program
