Why does Firefox need a refresh when high contrast theme is selected?

Shouldn't it change content immediately when it detects a theme change? IE 11 does this and it would be a really nice-to-have feature, especially when it comes to accessbility constraints...

cor-el thanks for the reply, NoSquint seems quite useful but unfortunately it does not cover my use case. I have a use case where an external application is able to dynamically set the selected theme at the OS level, that is, set it to High Contrast Black or switch it back to the default Windows 7 Aero theme, so you should assume that i do not have any control over what is happening at the OS level regarding the selected theme, hence cannot "disable a high contrast theme in the Operating System".
I see that some basic UI elements such as the select box arrow handle and radio buttons change immediately, but the overall outlook of the page (e.g. background colors, text colors) do not. Could this be solved with me implementing a Firefox extension which would interface with the system "theme-changed" event and perform a re-rendering of the page at that point? I am currently trying to find some info on this...

Why does the flash video have much higher contrast when the window is maximized?

When using Mozilla Firefox, any flash videos like those on youtube, when maximized, shows much higher contrast. The video becomes so dark that it is pretty difficult to view it. When zoomed out, everything looks normal.
The work around I ended up using, was to maximize the window using ctrl++ option without using the "fullscreen" button. It is a hassle, but it works. Does anyone know why this happens?
I use Mozilla FF 19.0.2. Btw, this doesn't happen on Chrome or IE.

Why does Firefox no longer launch when I double-click the icon?

I found an article on the support site that suggested creating a new profile, but the run command did not launch profile manager. I tried uninstall/reinstall, but it does not change behavior. When I click the icon, I get the hourglass for a moment, and then nothing. I'm on WinXP. On 10-14-11, I thought I saw a pop-up menu saying Firefox was updating (I did not initiate it, nor was I presented with a confirm pop-up), but it was very brief, so I'm not sure. After that day, Firefox would no longer launch. I've not made any system changes, or installed any programs.

See:
*http://kb.mozillazine.org/Browser_will_not_start_up
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Why does Firefox freeze my computer when I click on an email address or link to a page that asks for contact information?

when i click on an email link, my computer freezes and firefox will open new tabs until i force quit the application. i downloaded the latest version of firefox for a mac, but it did not help. how do i correct this problem?

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.14) Gecko/20110218 Firefox/3.6.14
When I click on a mailto: link, Firefox freezes. This is new for me as of 3.6.14 (not sure if it existed in prior versions because I hadn't clicked a mailto: in a while).

Why does Firefox need to see what websites i have been to and turn on the camera without my knowing?It seems the permissions are getting too intrusive.

I have always liked Firefox the best of all browsers, but will not be installing it on any mobile devices if it really can do whatever it wants to do like it seems from the permissions screen.

hello, these permissions are used to allow the import of the history from other browsers & for the [https://hacks.mozilla.org/2012/04/taking-pictures-with-the-camera-api-part-of-webapi/ camera api] - please also refer to the following article which explains all the permissions: [[How does Firefox for Android use the permissions it requests?]]

Why does the PDFs' name change when i view them in the iBooks app?

i have some past papers and marking schemes in my iTunes library....when i sync them to my iPad, they appear just fine....they are there just the way i named them and all...
but when i open them, the name changes to some coded-ish name with lots of numbers and all that....
is it possible for me to change some setting and save the name i want for those PDFs? Or am I going to have to live with this madness?
please help!

Why does Firefox comsume my computer when in Yahoo Mail

For the past week, something is effecting Firefox when in Yahoo Mail. It does not happen at any other web site.
# I do not allow automatic updates of any kind. No changes or additions (unless sneaky stealth attacks?) had been made to Firefox since update to version 12 in May. The only add-on I have is the Mozilla Archive Format, which I've been using for years.
# Windows and various security applications are up-to-date as of very recently.
# Several up-to-date anti-malware programs have found nothing on my computer.
# I tried Chrome and Opera. They do not have this problem, but I don't like either of them.
# I uninstalled Firefox, deleted everything related I could find, downloaded the current version (13) from Mozilla, installed, and rebuilt all my preferences. I got my bookmarks back by restoring from a bookmark backup. This changed nothing.
# I tried "Restart With Add-ons Disabled" in Firefox, but that did not help.
Firefox starts doing something very intensive once in Yahoo Mail. Sometimes it is in this state when it displays the first screen of mail boxes after I sign on. More often I can do a little bit of something, such as open a mail box or a single e-mail therein before the problem starts. From my perspective it starts this aberrant behavior just when I click on the next thing: open another e-mail; open a different mail box; delete an e-mail.
Normally while in Yahoo Mail, or at any other web site, Task Manager reports CUP usage at from 0% to 5%, occasionally a few percent more for a very brief flash. When this Yahoo Mail thing starts
# The CPU usage jumps to 25%, with occasional bursts up to 30+%. Task Manger shows it is due to the process firefox.exe*32.
# The browser will not respond to any controls. I can do nothing with the keyboard or mouse. No menu will open. This has never ended by itself.
# Task Manager reports the immediate drop of network activity to zero -- nothing going on over the phone line -- or so Windows thinks. Disconnecting the phone line does not release the browser or lower its CPU use.
# A few times the entire computer has locked. I have only been able to get out of it with the hardware reset button.
# Sometimes Firefox is totally unresponsive itself but I can cancel it via Task Manager.
# Sometimes the one and only thing in Firefox that responds is the "X" in the upper right hand corner. The browser screen disappears immediately.
# BUT, Task Manager shows the process firefox.exe*32 still running at 25% CPU. I can end said process with Task Manager, whereby CPU usage immediately drops to 0%, or somewhere close.
# Whatever is going on through Firefox prevents me from doing what I want -- and it seems probable that IT is doing something I don't want done, although I have not yet seen symptoms of that.
Where can I go from here?

Hi,
You can consider the [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems Reset Firefox] feature via '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information'''. If it is okay, you can then install the Mozilla Archive Format add-on.
If you have security software installed you can try to delete all existing entries for Firefox and its sub processes in the different configuration modules and try to fully trust/allow Firefox afresh. Even after network access is completed, Firefox would still need unlimited access to its disk cache/memory as well as its files. Please see [https://support.mozilla.org/en-US/kb/Firewalls this].

Why does Firefox Mobile stop loading when using VPN?

When I'm connected to Private Internet Access VPN on my phone (using their app in the play store) occasionally Firefox gets into a state in which no webpages can be loaded. I can fix the problem in one of two ways: (1) use Google Chrome for Android or any other app that uses the internet or (2) disconnect from VPN and use Firefox without that protection. Sometimes when I reconnect to VPN, Firefox pages will load again but sometimes not.
The loading bar in Firefox Mobile always gets stuck in the same spot, which I am thinking could be diagnosed to determine which part of the http protocol it might be stuck at. I am hoping I can attach a screenshot.
I really believe in what you guys are doing. Keep fighting the good fight.

It could possibly be that the dns is failing, but to be sure there would need to be a log and need to be tested on lte and wireless to see if its consistent.

Why does firefox need to be closed to delete cookies & temp files

Only firefox seems to be this way -- under Windows, when I run a cleaner to delete temp files and cookies, firefox temp files and cookies can't be deleted unless firefox is closed. Can't this be fixed?

Other browsers don't seem to have his problem. i enjoy be being able to click on one item and having things cleared without fuss or bother. I'd prefer not to auto delete with each close nor do I want to have to manually hunt down with Ctrl+Shift+Del. I'm aware of those options. I was wondering why firefox still worked that way. Definitely a disadvantage for me using it. reminds me of the story:
A guy goes into a store to buy a suit and the clerk gives him one to try on:
Guy, "Hey one sleeve is longer than the other."
Clerk says, "Just shift your shoulders like this and it will look fine, see."
Guy, "But the pantlegs are uneven."
Clerk, "Well, just shift your weight onto one hip and, yes, see it looks fine."
Guy, "But the collar rides low on one side."
Clerk, "Here, hold that side in place with your chin against your chest like you're holding a violin. Voila!"
These accommodations go on for bit and the guy, somewhat exasperated but worn down, buys the suit. He wears it out of the store and down the street with his chin clamped to his chest, and one leg sort of dragging and his shoulder cocked, etc.
Two doctors walk past him and one says, "Oh that poor fellow," and the other says, "Yes, but he sure had a nice looking suit."

Why does Firefox open new tabs when HOME is clicked?

I just upgraded to version 29.0 from a 4 year old version and I'm experiencing a problem that I can't imagine how to correct. I have two home pages set in my config, so that when I open firefox I get two tabs displayed. My Home Page field reads "https://www.google.com|https://news.google.com" When I open Firefox I get two tabs, one for Google and one for Google News.
On my old version, if I was in the first tab & navigated to www.hp.com and then later clicked HOME, Firefox would load that tab back to google. If I was in the second tab, it would navigate that tab back to google as well. The multiple Home page option was just a great help for initialization.
Now, regardless of what tab I'm in, when I click "HOME" Firefox opens two new pages, sets the first to my first home and the second to my second home and now I have FOUR tabs open. Click home again and I have 6 tabs, again and 8 tabs, etc.
There has to be a way to fix this. The HOME button is supposed to operate of the current focus, just as it does if you have a single home page specified.

Hi Stan, what both Ed and I are saying is that the first of your home pages should open ''in the current tab you're viewing'' -- the way you want -- because that's what happens for us.
Could you repeat the test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?

Why does Firefox needs permission to make changes to my computer?

Yesterday, when I tried to start up Firefox, a window popped up and asked if I wanted to allow the program (Firefox) to make changes to my computer. It has never asked me that before and ever since yesterday, whenever I click to run it, the same window pops up. It doesn't specify what changes Firefox is making and I just keep clicking "allow." I have Windows 7 and yesterday, I also downloaded Sleep is Death by Jason Rohrer- a simple, small game, but I don't believe it asked me to change anything in Firefox. Can anyone tell me either what the changes are or how to stop Firefox from requesting to make them?
== This happened ==
Every time Firefox opened
== Yesterday

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.
You also need to check the Properties of the firefox.exe program in the Firefox program directory.
If you can't make the changes then you need to start Windows Explorer as Administrator.

Why does firefox update itself even when i tell it not to? Everytime it updates itself it messes up and crashes, make it stop. I like firefox but if I keep having to unistall and reinstall it ever month to every other month I am going to be done with it

Fire Fox updates itself even after I tell it not to. The new version it updates to crashes, adobe flash player doesn't work on it and it takes forever to load when it does work. I have used fire fox for years now but if this keeps up I will find something else to use.
== This happened ==
A few times a week
== When you came out with fire fox 6.6 or whatever

I also have this problem of Firefox updating by itself even when I turn off auto-update.
For whatever reason, there are situations where you do not want to update or download a large file, because you're working offline, have a slow connection, or have a very low download allowance etc. Usually the update doesn't work and cause Firefox to crash. After that it cannot be started again. This is with Firefox Portable but I think I've had this problem the normal Firefox. With the portable version I can just back up a single folder but it is still time wasting and annoying.
I've noticed that when I start Firefox with auto-update turned off, it changes the options to auto-update, it also does this periodically. So every time I start Firefox I have to turn off auto-update, and I have to do this from to time because Firefox will by itself turn back on the auto-update.

Why does Firefox need to control my mic and my camera?

To install Firefox on my phone I must first accept these permissions.
Hardware Control:
Record audio:- Allow application to access the audio record path.
Take pictures and video. Allow application to take pictures and video with the camera. This allows the application AT ANY TIME TO COLLECT IMAGES THE CAMERA IS SEEING.
I have stopped using Facebook Apps and many Google products because they what this sort of contol and basically I don't trust them.
Why do so many apps need such spying power? and where can I download an old version of Firefox.android that pre dates this control freaky version? After all it used to work just fine without.
Thanks
Jonpon

making permissions optional and controllable for the users is something that would have to be implemented on the OS level. if you have a device with android 4.3 or above it might already work through this hack: www.androidpolice.com/2013/07/25/app-ops-android-4-3s-hidden-app-permission-manager-control-permissions-for-individual-apps/

Why does Firefox get hung up, when opening new pages? I've tried disabling plugins and extensions to no avail.

Initially, when I open Firefox everything opens very quickly. However, after several minutes it gets hung up when opening new pages. I have close the browser and reopen it to start over. But each time it does the same thing. Works well at first then poops out. The trouble started yesterday. Before then, I never had any problems.
I've tried disabling all the plugins and extensions, but it doesn't make any difference.
