Firefox Support Forum

I want to increase firefox's memory cache.

From the knowledge base, this seems to be the value that should be changed.

http://kb.mozillazine.org/Browser.cache.memory.capacity

To verify the change, I checked "about:cache?device=memory".

No matter what the value "browser.cache.memory.capacity" is, under the section "memory",

It shows "Maximum storage size: 28672 KiB".

(the disk cache section shows correct values, btw)

Is there something wrong here?

FF ver, 52.6 ESR, 51, and several other old versions.

I cannot close Firefox on my Macbook. This is a new problem. Macos Sierra 10.12.2 (16C67). Firefox Version 51.0.1 Build ID 20170125094131 I have to restart the machine . . .

Just installed Firefox & Adobe Flash Player.Firefox is my Default Page instead of Chrome.When I click on a Game in Facebook it says,the Question I asked above.It says:Context 3D not available! Possible Reasons:wrong wmode or missing device.I'm not a Computer Whiz,just like to play my Games.I installed Firefox,because my Games on Fb where running slow or it says:Wait or kill.I don't even know what a wmode is.Please,help.....Thank you

I am using extension for Firefox - Zoom page that is showing zoom level of the page. Recently after firefox update I discovered that this is Zoom level indicator on the right side of the address bar. That's a bit annoying to see double indicator at once. Moreover, I'd like to use the extension indicator instead of standard firefox indicator in the inappropriate place like address bar. Is it possible to remove or hide it somehow? Thanks

I have just downloaded & am running the latest version of Firefox.

In my 'Downloads' folder there are now four versions of the Firefox Setup: three copies of 43.0.1. and one copy of the latest, 51.0.1.

Which of these can I safely delete?

Many thanks

Since the 51.0 upgrade yesterday, my top menu line keeps disappearing, forcing me to constantly hit F10 to get it back. I want it up permanently... I use it a lot.

Good morning, I'm trying to open the site www.progettod.com and I receive the error code: SEC_ERROR_OCSP_TRY_SERVER_LATER. I am the webmaster of the site and the provider is www.aruba.it. With other browsers I can successfully open, and even with Mozilla could until yesterday. Not today: what happened? Thanks for the help, Gianmario Malfatto email: g_malfatto@yahoo.it

Hello. I can't seem to find a way to do this. I want to use a HCT in windows but want FF to IGNORE this and act as it normally would with a normal windows theme.

That's it really. The changes FF makes when it detects a windows HCT, I'm sorry to say, can mess up the appearance of many websites. Removing pictures etc. As I say, I want it to do NOTHING different if I use a windows HCT.

P.S. I have tried messing around with whatever colour options I could find, but can't seem to find what I am looking for.

I have searched Mozilla support for Location Bar without success. It shows me links to other Firefox bars, but no Location Bar. And yet Tools-Options-Privacy clearly refers to Location Bar. I have never seen such a bar in all my years of using Firefox. I had hoped Location Bar would be defined somewhere in Mozilla support but no such luck.

I logged into the Dennie's restaurant WiFi. That seemed to go well. When I clicked a Victoria's Secret tab FF sad that the Victoria's Secret cert was invalid or some thing like that and would not let me add an exception or go to the tab. Dennie's WiFi is not secure and does not require a password. How do I tell FF to warn me and let me go to the site anyway. There are several sites that have the same problem.

Many years ago in win XP and IE6 we did can set a *.mid music in pages background and play. Why new browsers don't do? the big feature of midi files is tiny size of them. i have searched in google, and midi support is in HTML5 schedule. but the Google Chrome that supports almost all of HTML5, don't play *.mid files. what means?

"You don't have permission to access "http://www.homedecorators.com/?" on this server." when I try to access this website??

How do I give permission or overide, woks on my blackeberry browers but not windows 10? Mozilla, and Edge, same conflict.

Help

I know how to fix it, well usually. I've gone into about:config and searched taskbar but when I reset the "user defined" it seems to revert back to "user defined". Anything I can do to fix this?

Edit: I've added pictures to provide some idea to what I'm talking about.

I feel like I'm going crazy. The sparkle emoji always renders as unicode but every other emoji is fine... see attached pictures.

This doesn't happen in Chrome--only FF--so I think it's a Firefox issue. But WHAT?? I tried clearing my cache. I can't think of anything else? I can't find anyone else with this same issue online. I really really don't want to use Chrome but this is driving me nuts.

As of 1/26/2017 I started having problems going to websites directly from desktop. Sometimes it works and other times it does not. (going to the same site) I power up or restart computer and it works for a couple ot times and thereafter it just sits at the home page which in my case is 'about blank'. I can get to all the websites if I just type the name in or use the bookmark Also if I exit from site ( click on X on top) and try to load another copy of firefox it sometimes says that it is still running ( sure enough I see it on the task bar although I have exited it by clicking on X. My platform is win10 (64 bit) Firefox version is 51.0.1 (32 bit) I re-installed it. Made no difference. I cannot test this without the addons as I would already be on the homepage. What should I try next? This used to work since the beginning of time. Thanks George

When I went on my hope page this morning I get a lock with a red line. The message when I click on the lock says the site is not secure. It seems that my other sites are secure since they have a green lock with no lines. How do I correct this? I contacted my internet provider and was on the phone for quite a while trying to correct this to no avail. Your help would be greatly appreciated.

Thank you. Diane Gaber
