Why does firefox slow down when you reopen it whilst a file is still downloading?

If im downloading a file and close the browser so that only the download manager is left showing ion the taskbar and then attempt to reopen firefox to browse something new, it runs incredibly slowly.
So slow in fact that I have to close it (which in itself takes a while) and use internet explorer until the downloading has finished.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Firefox slows down when opening a site with animated gifs

After updating to FF4, I find that whenever I try to open a page that has multiple animated gifs on it, firefox slows down tremendously. CPU usage goes up to 50-75% and all animated gifs are moving really slow.
It's not only large animated gifs, but it also occurs on forums that have animated smilies. I never had this problem in FF 3.6 nor any other browser (IE, Chrome, Safari). If I start FF4.0 without any add-ons or plugins it does the same thing. Even with a fresh install. Does anyone have a solution to his problem? Since I can't use some of my favorite sites now with FF, without my pc slowing everything down.

Disabling the hardware acceleration worked for me!

For people with an unlimited data plan...does it slow down for you after 2GB?

Ive had my unlimited data plan since i joined AT&T back in 2008 when i bought the iPhone 3G...ive been able to keep it for my current iPhone 4 and now ill be upgrading to iPhone 5 and was wondering if anyone else with an unlimited data plans suffers slowing down of data after 2GB? it mite b more than 2GB but it def does slow down...will this continue to happen or it is it just me?

Click the "what you need to know". If you exceed 3GB you will be throttled, and you should receive a text message about it the first time you go over.

Why does firefox go crazy when I try to email from a website?

When I want to contact, say, customer service of a company and I use their email "form" on their website Firefox goes insane
and opens 100 plus tabs and blinks, going so fast that I can't possibly shut down all of the tabs because it's making more
than I can keep up with. This happens EVERY time I try to email from any other place rather than my personal provider. It's just
Firefox that does this, not IE. I have to shut everything down, which means that whatever I'm working on gets lost. I'm about
ready to dump Firefox. Can you stop this for me? I'm using Windows 7, IE 9. Cache is clean and no virus found

You get tabs opening endlessly if you select the Firefox program to handle a file when you get an "Open with" dialog.

You can rename (or delete) the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

Why does InDesign create widows when you split a paragraph?

Take a look at the two screen grabs. In this first one the price £48.25 fits at the end of the fourth line.
But I want to split the paragraph at that point. Look what happens when I do:
Why does it do that? As you see from the first example, the type will fit happily on the line above with the same hyphenation and justification settings. Why should splitting the paragraph make a difference?
This feature enrages every production journalist on my UK national newspaper every working day of our lives. We don't like to put minus tracking on text and the only other way I know to counteract this effect is to reduce the word space values in the justification settings for the affected paragraph (we're working in Single Line Composer, by the way – Paragraph Composer makes it even worse). Sometimes even that doesn't work without everything looking too squished. If we can't edit the text to solve the issue (and why should we if we're otherwise happy with it?) then we have to construct a fake new paragraph using fixed spaces for the indent and baseline shift to create the 1pt space we insert between pars.
The font in this example is Corporate E Bold, in case that has any bearing.
Is there any other way round this, some mystical unknown setting that turns it off? If not, was it ever fixed in later versions of InDesign? My company uses CS3 and is not likely to update it for many years.
Thanks

Because it uses paragraph composing to adjust for the best possible spacing within a line calculated on other lines here is how it works there are two types
Adobe Single Line Composer
and
Adobe Paragraph Composer
Paragraph composer is the default - and here's the rules on how both work:
Adobe Single-Line Composer.
Some programs use single-line composition to flow text. It goes line by line through a paragraph and sets each line as well as possible using the hyphenation & justification settings. When you modify the spacing of one line then the lines above and below that are not taken into consideration. If you adjust the space within a line it can cause poor spacing on the next line, which as they say in the business - tough luck.
When you use Adobe Single-Line Composer, the following rules apply:
Adjusting word spacing is preferred over hyphenation.
Hyphenation is preferred over glyph spacing.
If spacing must be adjusted, removing a space is preferred over adding a space.
Adobe Paragraph Composer
Adobe Paragraph Composer (which was called the Multi-Line Composer in previous versions) is turned on by default. It takes a broader approach to composition by taking the entire paragraph compoistion in one go. If you have a poorly spaced line it can be fixed by adjusting the spacing in the previous lines, so that the Paragraph Composer reflows the previous line.
The Paragraph Composer is has the following rules:
The evenness of letter spacing and word spacing is the given the highest priority. The possible breakpoints is determined by how much they cause word and letter spacing to vary from the desired settings.
Uneven spacing is preferred to hyphenation. A breakpoint that does not need a hyphenation is preferred over one that does.
All possible breakpoints are ranked, and good breakpoints are preferred over bad ones.
The paragraph composer is more sophisticated than the single-line option, offering generally better overall spacing because it sacrifices optimal spacing a bit on one line to prevent really bad spacing on another, something the single-line method does not do.
There is one frustration in dealing with the paragraph composer: When you try to edit text or play with tracking to get rid of an orphan or widow, the paragraph composer keeps adjusting the text across several lines, often counteracting your nips and tucks. The single-line composer doesn’t do that.

Why does Firefox keep crashing when I use it on my Dell Precision computer w/XP operating system?

Well, this is embarrassing.
Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page.
You can try:
Removing one or more tabs that you think may be causing the problem
Starting an entirely new browsing session

If Firefox crashes frequently but stops crashing when you are in Safe Mode that is a pretty sure sign that there is something wrong with your individual setup of Firefox on your Windows 7 machine.
(The 99 others claiming to have the same problem this week probably have their own distinct and separate problems - if you are one of those 99 it may make sense to start your own questions about your problems, if you do not see suitable answers).
Many malware problems would continue even in Firefox's [[safe mode]], so the good news is that malware may not be your problem.
Note that safe mode does not disable plugins, you may wish to consider testing with your plugins disabled, just in case they are interacting with something. To temporarily disable plugins use
* '''Firefox button -> Add-ons -> |Plugins|'''
You do not list the Firefox extensions that are in use, maybe one of them is a problem. I suggest you try Firefox with half of them disabled, if that solves the problem, the troublesome add-on may be in the other half, disable them all and then try with half of the other half enabled. (If you have more than a handful of add-ons it is faster testing like that than enabling or disabling one at a time)
One very important question is how do you know Firefox is crashing ? <br/>will you please explain exactly what happens, and what if any error messages you are seeing. (If firefox freezes/hangs that may be different from Firefox or the OS crashing, and require different solutions).
On a general note the following articles may help with troubleshooting:
* [[basic troubleshooting]]
* [[troubleshooting extensions and themes]]
* [[http://kb.mozillazine.org/Standard_diagnostic_%28Firefox%29]]
and if the problem is a true crash
* see [[firefox crashes]]

Why does Photoshop 6 crash when I try to open a file?

After opening Photoshop 6 I click on "open" to open a file. sometimes the program just closes down, and sometimes it opens a folder but I then get "Photoshop has encountered a problem and needs to close." Effectively, I no longer have the use of the software. What can I do to eliminate this problem?
(I am using Windows XP Professional Service Pack 3.)

Is that photoshop 6 or photoshop cs6?
I'd reset the photoshop preferences by holding down the Shift+Ctrl+Alt keys just after starting the launch of photoshop.
Keep holding the keys down until you get a dialog asking if you want to delete the adobe photoshop settings file.
Press Yes because you do.

TS1363 why does Itunes shut down when I purchase songs.also when trying to download updates it fails to update.I am using windows 8

when I purchase songs Itunes shuts down.also when I try to update I tunes I keep getting an error message that says failed to download

I appreciate your response but not sure now if it could have been anything in that answer because.......
This problem appears to have gone away, not sure why but I have a possible theory. This is only a theory on my part as I'm not knowledgeable on the inner workings of Firefox. When I installed Firefox 18 it had all the automatic updating options turned on by default. By the time I turned them all off, I'm assuming it had started to download updates for all the plugins and addons, like java, quicktime etc. etc. etc. even though I hadn't personally initiated those downloads and updates. My theory is that once those downloads had started, even though I had turned off the automatic updating, it was going to continue downloading the updates that had started and was not going to stop until it had done so.
I do not disable the anti-phishing and evil website detection stuff but I seriously doubt the updating for those items would have consisted of 89 megabytes of data but I could be wrong.
So for now, I'll close this out and mark it solved and continue to monitor to see if I have any more "weirdness" go on.

Why does Firefox keep updating when it knows it will not be compatible with extensions and plugins?

firefox now will not let me run videos or my birthday e-cards. i tried all of their solutions as much as i could but am not even vaguely a techie at 61.
why do the insist on updates that render stuff i use daily useless? why do I have delete or downgrade stuff to get things to work? this is total nonsense.
i may leave firefox for anything else given this CONSTANT issues..nearly every update something is now not compatible..folks are not happy, firefox. i know i am not.
ISSUE: videos and e-cards do not work. period. i have downgrade flash and messed with realplayer to no avail.
HELP and SUGGESTIONS please

PLEASE POST IN YOUR OWN NEW THREAD.
This is getting complicated. Flash Player problems are not necessarily the only subject of this thread and it is a solved thread so it would be best to open a new question.
The situation changes as new versions of Firefox and FlashPlayer are released, and both have updated within the last few days.
Regarding FlashPlayer problms with Flash 11.3 there appear to be three problems
* Real Player - that is best dealt with as a separate problem - so a first question has to be are you using Real Player and if so does that include video recording/downloading features ?
* Protected mode <br/> Many problems on Windows Firefox relate to the use of protected mode by the Flash Payer 11.3 . Also note this is an issue only affecting recent Windows OS s .
*Protected mode setting <br/> it is possible to set this or unset it manually, it is also possible for installers to set or unset this so not only the version, but where you obtain it and what the installer is can make a difference.
The security level of these versions also needs considering, remember protected mode is itself a security enhancement.

Why does firefox change fonts when I am trying to download or get help, click and enter keys are disabled why?

I recently did a clean install of windows7 after returning from Europe and installed Mozilla firefox being fed up with microsoft and google .
Fire fox seemed to be working ok but 7 out of 10 downloads were failing, and it seemed that every ebsite entered in the address bar turned into a question.
There was no save shortcut, or paste buttons just a set of to me useless buttons first html, last html, then when I tried to contact help all of a sudden I got a "install fonts" notice and the enter key stopped working,
and any action key was also disabled without advising me.
It appears that either Mozilla or someone doesn't want me using firefox.
I also noticed that the clean disk and other utilities didn't work and that the temp and temp internet folders were empty when I tried to open them but they actually had some 25 megabytes in them when queried as administrator. I also noticed a quick flash reference to Jscript=void,
and my 32 bit computer suddenly started up as a 64 bit Turion.
scan and system clean said machine was clean.
Whats going on here?
I am not on my machine, I can't contact you on it because the enter button has been disabled by font change.
Maybe this robot needs some help too!

Can you undo the system restore?
Note that using System Restore can cause your Firefox installation to get corrupted because not all files are restored (only files in a white-list), so be cautious with using System Restore.
*You may lose data in the Firefox profile folder like .js and .ini files pr profiles.ini can be affected.
*You may need to (re)install software that was affected.
In case you need to reinstall Firefox then you need to delete the Firefox program folder before reinstalling to make sure that all files get replaced.
A possible cause is security software (firewall,anti-virus) 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 and the plugin-container 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 7 freeze when I paste a filename when printing to a file using Microsoft XPS Document Writer?

This is more of a bug, and it doesn't seem to happen all the time.
I like printing web pages to Microsoft XPS Document Writer (.xps) format. FF7 seems to freeze often when I paste a filename (usually from copying something, like the title, from the web page itself) after trying to print to a file using Microsoft XPS Document Writer. I think it may be that I wind up copying some special formatting (or maybe a line break) and that causes FF to freeze (I then have to force-close it using Task Manager). Just a bug that I hope the developers will note and fix.
Another question, not quite related to the above, but is there a way to save an html web page to save only the text stuff? When I save to Text File in Firefox, I usually wind up with all the html crap in it too, when I just wanted the text content portion. TIA.

Why does Firefox 4 not let you save a pdf document using the "File" tab. Internet Explorer * give you an option..."Save as....". Can I get same function with FF4?

Can't save a pdf file using the 'File' tab in FF4.

Clicking "Save Page As..." in the Firefox menu should work fine. However, if the server you are downloading from is set up incorrectly, Firefox might recommend a filename which does not have the ".pdf" extension (e.g. "get_file.php"). In this case type ".pdf" at the end of the file name.

WHY does firefox come up when I had a attack on my pc as the sender?

while on Facebook and trying to view uploaded video...my NORTON blocked several attacks ,when I checked who was sending viruses (x6), I discovered that the IP matched Firefox as the sender...I find this to be unfair as well as preposterous and a bully orientated ,indigent ,crooked act of illegal mischief ... a clear act that may cause legal action to be implemented if this continues.
Firefox should not break laws to bully-in requests to upgrade in a robotic way.
If this continues I will file an action in court resulting in millions of dollars worth of changes and monetary losses.
thank you.

Firefox the web browser (from mozilla.org) nor Mozilla will NOT send any form or viruses, malware or toolbars into Firefox as it would hurt Mozilla far too much for any little gain.
You seem to have the current Release Firefox 30.0 so there should be no more updates until Firefox 31.0 unless a chemspill update (30.0.1) was warranted in meantime for security and or stability fixes.
So you are considering filing a lawasuit for Firefox prompting you for a Firefox update?.
There are other reasons for connections like say looking updates for any Extensions and Themes you have installed, updates to a blocklist for Extensions and other safe things like mentioned at http://kb.mozillazine.org/Connections_established_on_startup_-_Firefox
