Hi,

Where does Mozilla Firefox saves the files from add-ons? Don't know if it is from Windows update or from Firefox update, but my add-ons settings keeps on resetting and I lose a lot of data from them because of that. And if I know where Firefox saves those files, then I can make a backup for them.

When I try to access my gmail account, Firefox says "the page isn't redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept

   cookies."

I've tried removing cookies, preventing firefox from accepting cookies, and restarting Firefox in safe mode. The best I can get is the log in page, but once I enter my information, I get the same message again. Any suggestions?

How do I prevent firefox from using HTML5 player in youtube and use flash player instead? I am not sure what advantage HTML5 has over Flash. I noticed that Flash plays smoother than HTML5 and there is also a difference in quality of the video at low resolution. HTML5 does not seem to have smooth streaming compared to Flash. I may be wrong and I am ready to learn the advantage of HTML5 over Flash. But until then I wish to revert FF to its previous behavior of playing in flash.

If there is no way of bypassing this player (html5), how do I set it to ask before I allow it to play the video? I dislike videos playing automatically as soon as I open the link or any websites (reason why I set Flash player to 'ask to activate').

Thank you for your generous help. :)

I'm getting this odd error with the standard install of FF since the last few updates every time I try to load FF (even starting up with a blank page) or open a new tab. Tried a fresh profile .. same result. Completely uninstalled FF & deleted the existing profile, then installed again ... ditto. Ran in FF safe mode .. ditto. Disabled hardware acceleration .. ditto. Scanned for nasties (ESET) .. nothing. Installed the latest portable version .. worked fine. Copied the old profile into the portable version .. worked fine. So what could be causing the installed version to give the 'Gah ..' error, both on starting up FF & opening a new tab, but not affect the same FF portable (same version)? The system is an ASUS laptop Win7Pro 32-bit. It's my wife's pc and she uses IE (gasp), so it's not a life or death situation. I'll use FF portable & update now & then unless there's a fix??? One final observation - the first time FF is run after an update or a fresh install, it oddly works then, but shut FF down & restart it .. and all I get is "Gah.." - Gah indeed!

Eu já tentei desinstalar pela própria página, configurei a página inicial em "Opções-->Geral", mas não consigo, não adianta, o firefox direciona sempre pra esta página (que eu odeio): http://www.22find.com:8080/newtab/?utm_source=b&utm_medium=cor&from=cor&uid=ST3808110AS_5LR1PTRDXXXX5LR1PTRD&ts=1359583568 Por favor, me ajudem a livrar meu pc desta praga!

For the past week or so I have been unable to play any Netflix videos in Firefox. Netflix works fine in other browsers and all other video streaming sites I've tried in Firefox still work. Initially the problem was that I would just get stuck on the red loading circle, however, after updating Firefox to the latest version (version 53), I now get an error message on Netflix telling me to check I have the latest version of Firefox, with an error code, F7702-1003. A solution posted from about a year ago involving changing the path in profiles.ini did not help, nor did removing pluginreg.dat.

I would be grateful for any assistance.

So I'm getting a error "Your browser does not currently recognize any of the video formats available" and when clicking the link, it says H.264 and MSE & H.264 are not supported. I used to get the black error screen for a split second before the video would blink and (I'm guessing) select another player and just play normally. Today is the first day that I've had this screen permanently displayed and it only shows up for a few videos. I can watch other videos on the same channel, just one or two that have the error.

It's the same if I try it in Safe Mode or with a new profile. I updated Firefox to 49.0, updated java, updated windows media component, and tried it with "media.windows-media-foundation.enabled" true and on false. No changes

I'm at my wits end with this one! I can watch the videos just fine in Chrome, but would much rather prefer to continue to use firefox as my default browser. Any help is appreciated. Thanks!

Never had problem with downloading files via Firefox from Google Drive until now...instead of file download I get tab page with following url: https://doc-04-c8-docs.googleusercontent.com/docs/securesc/jom0u67oa0tfigrh4n9sea600sv1527e/s7srbc6ckut7m2fm1eeurtos8v4ecb70/1493064000000/07580902641423571478/07580902641423571478/0B1FDjJYZYLbhRTlLQmtERjVCZ2s?e=download&nonce=4ekqosb5geo8u&user=09357804788864382250&hash=t8fpbl8um4ju2acaskk56nd6e491l86b

Uploading to GD using Firefox works..MS Edge and Chrome download fine...reinstalled and refreshed Firefox..tried troubleshooting tips for download problems per Mozilla help page and community forum..no MIMEtypes folder exists in my profile folder..any suggestions?

I want to prevent pop ups, pop unders, etc. Literally not one answer was appropriate, so I am rephrasing the question. I want firefox to simply not even acknowledge the request to open ANY new window or tab from the html code, website, server etc. I don't even want it to alert me that is hasn't acknowledged the request to open a new window or tab. I don't EVER want to see a firefox window or tab or instance that I haven't directly caused via mouse or keyboard input, and I want it to be COMPLETELY transparent. How do I do that? (I don't care if the answer is long or technical.)

When open a new tab, using "+", I want Firefox to open blank page. But it shows all my visited websites from browsing history. "Blank page" is with pictures-hyperlinks of those webpages! How to get normal blank page without pictures-hyperlinks of browsing history without deleting all of browsing history?

Is there any option to start the firefox the safe mode without opening the firefox i normal mode

In Windows 7 there is an option to start the Firefox in Safe Mode in the Mozilla Firefox Menu

Hello,

I am using Firefox x64 on Windows 10 x64 platform. There are no unity plugin after installing web player.

Enabling of plugins preload according to https://support.mozilla.org/en-US/kb/windows-media-or-other-plugins-stopped-working does not help

I've gone through all the suggestions, troubleshooting listed here and nothing has worked in stopping this "hanging" business. It started earlier this week with FF16. So I tried uninstalling, clearing out any traces of it, profiles and all. R-installed with the previous extensions, plugins and scripts. Still did it. So I either disabled or uninstalled said add-ons. Still did it. Upgraded to 17, then 18. Same problem. "Not responding" every couple of minutes for just a few seconds, longer when I switched tabs. I'm a heavy tab user, but given the problem, I've gone down to no more than 3 open at the same time. Still hangs. So I decided to do a complete overhaul. Did a reset. I even thought it was my computer (Vista with SP2) which had been working fine and was slowing down around the same time FF was hanging and being a resource hog.

With FF uninstalled, with the help of Microsoft support, I worked on the laptop. Uninstalled my usual programs, including AV (which had avast). Moved all my files to an external hard drive. In essence leaving my computer with bare bones. Did a defrag and a system restore. I reinstalled av, then ran it. All clear. Ran malwarebytes. All clear. Ran registry clean. All fine. So I reinstalled FF18 and did not use any add-ons. Still hanged. Went up to FF19 beta thinking whatever but there is, would be cured. And it worked fine witn no add-ons. So I started installing my usuals, but leaving only the most important ones, ABP, No Script. Was ok so I added greasemonkey, smartest toolbar, download statusbar and unhide passwors. All which I've used for years with no problems. And FF19 worked fine with no hanging for like a day and a half. Today, (jan 24) not only is it haning and not responding again, but it's doing it more frequently and for longer.

FF never has crashed, it just hangs and freezes. My job is ALL online. I don't like Chrome (not user friendly to me). I'd rather avoid using IE. I'm a user of FF since day one, but this is stressing me out because I cannot do my job properly.

What can I do to make it stop? My only other option is to just forget FF and try and get used to Opera.

Now that I think about it, could this hanging problem be related to the Java issue that has come out publicly recently?

I don't know what else to do. I've tried everything that has been written here. Trust me, I've wasted 2 days on this issue. Time I'll never get back and I could've used to do work.

Thanks

I cannot access a clients site that I'm working on due to an HSTS error, I used to be able to bypass this with test.currentTimeOffsetSeconds, however it seems to not work anymore.

I use Firefox for development because it has better tools than any browser I've use in the past, however this is a real blocker for me, since the sites I'm working on don't have DNS names yet and can't get updated certificates till then.

I've also manually added an exception in the certificate options, though that also didn't work.

Please guys, I've always been pushing people to use Firefox, though if it starts limiting my options without any way to bypass it if I feel I need to do something, then I'll be forced to go hunting for a browser that gives me more freedom, not to mention this is costing me work hours.

Is there a way to hide the arrow of a <select> element in Firefox 30 using CSS?

Maybe there's a hidden (pseudo) element or property I can access?

I couldn't find anything on https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Mozilla_Extensions. I tried a couple of -moz-appearance values, but they either add styling I cannot remove, or they do not allow restyling, or they still show the arrow.

In Firefox 29, there was a hack that worked, described here: https://gist.github.com/joaocunha/6273016 it no longer works in Firefox 30. There is also a bug about the unstylability of select elements here: https://bugzilla.mozilla.org/show_bug.cgi?id=649849. If anyone can point me to a changeset that might have changed this in Firefox 30, I'm also interested. I know I can hide the arrow by overlaying an element, or by nesting the select and hiding the overflow, I’m not really interested in that.
