How do I optimize my Firefox browser on a MAC?

My computer has slowed drastically the last 2 days and occasionally the browser crashes. I have been advised to optimize my browser.

Hi megdclark,
Here is an article that will help you show your iTunes sidebar:
iTunes 11: Frequently used features
http://support.apple.com/kb/HT5649
Show or hide the Status Bar and Sidebar
In iTunes 11 you have the option to turn the Sidebar and the Status Bar on or off; they are off by default. To do this in the menus, go to:
Show Sidebar - Choose View > Show Sidebar (this feature will display iTunes features on the left side of the application including Library, Store, Shared, Genius, and Playlists).
Show Status Bar - Choose View > Show Status Bar (this feature will conveniently display the number of items and playback time for a category, for example, music or movies).
Thanks for being a part of the Apple Support Communities!
Regards,
Braden

After mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

after mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

See if this works for you.
Open up Tools > Options -> General and toggle the first preference - '''Allow Firefox Developer Edition and Firefox to run at the same time''' - to get back to your previous Aurora Profile. It will tell you to restart Firefox.
If there's a check-mark in the box for that pref it shows the Aurora Profile, if you remove that check-mark it shows the Developer Edition Profile.

How can i restore safari web browser on my mac book pro?

how can i restore safari web browser on my mac book pro?

Backup your system/data then start up holding down Command + R and select to reinstall your OS X. You have not mentioned which OS X you are using. If you have somehow deleted the Safari App for some reason, you need to reinstall the OS X to reinstall Safari properly. You should not lose any data, but if you do, then that is what the backup is for.

How can I undo the firefox browser refresh and get my old browser & settings, etc. back?

I accidentally did the browser refresh yesterday (2-17-2015) without reading further down the page on what that would do. It of course gave me a fresh browser. The problem is I lost my customized appearance (Dark blue fox, I believe), the add-ons I really have come to really on, etc. Firefox did create a folder with the old settings. I'm not that savoy understanding how to get that folder to open, run, whatever it takes to put all the things I want back into working order on the firefox browser. Please excuse my lack of proper terminology, jargon, etc. I know enough to be confused and everything I have learned IT has come from stumbling through it over the last 15 years of having my own PC.
Any help would be greatly appreciated!
Please keep any solution details as plain and simple for a novas to understand and execute as possible.
Many, many Thanks, Ottodewy

When you reset (refresh) Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported and the current profile folder will be moved to the desktop to an "Old Firefox Data" folder.
Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone.
It is possible to recover data from the old profile, but be cautious not to copy corrupted files to avoid carrying over problems.

*http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
Note that is is also possible to use the Profile Manager to create a new profile.
That way the current profile isn't moved to the desktop, so you can return to it at any time.

How can i configure Mozzilla firefox browser to show menubar by default using only about:config options

I'm trying to configure mozilla firefox browser version 36.0 to use in a silent install deployment and so far i've managed to configure almost all settings that i wanted , except the menu bar.
I use a configure file with the options i want for example :
pref("browser.startup.homepage", about:blank);
pref("browser.shell.checkDefaultBrowser", false);
How can make the menubar visible by default ?
Thanks in advance !
Best Regards
Filipe Conceição

That is not possible via prefs on the about:config page.
Only the toolbar customization is stored in the browser.uiCustomization.state pref.
The setting what toolbars are visible is set via the xulstore.json file.

How do I set the FireFox browser to be compatible with my Brother MFC-8840D printer so it will translate color into grayscale when printing from a webpage?

Hi, I have a question about setting the FireFox browser so it is compatible with my Brother MFC-8840D printer to print in grayscale. Currently, if I print anything in color, like a Google Map, the colored parts of the map show up blank, whereas the color should change to grayscale in a black/white laser printer. Brother tech support told me to contact Mozilla about this issue.
In comparison, when I print a Google Map on my dad's HP printer (also using FireFox browser), the color map prints perfectly in grayscale, so I can see all of the street lines.

The Firefox 3.5.x branch has reached end-of-life and is no longer maintained. 
You will no longer receive security updates. 
You can update Firefox via "Help > Check for Updates" or download and install the latest Firefox 3.6.x. 
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.
* http://www.mozilla.com/firefox/4.0/system-requirements/
If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder], so you won't lose your bookmarks and other personal data.

How do I open a Firefox browser window?

Man, is this frustrating!
I have a Samsung Galaxy 10.1. I downloaded Firefox from Google Play. I synched it. I added the "full screen" add-on. So where's the browser? I can't even get to anything that will let me type in a URL or a Google search term, much less the same bookmarks and tabs that I have on my Windows laptop -- which is what I thought "synch" was about.
I tried uninstalling and reinstalling. Didn't work. I'm stuck at a "top sites" screen that gives an array of nine tiles. Not a single one of those tiles is a Firefox browser of any kind at all. What the (blank) am I supposed to do?

Thanks for your ongoing help. (And if this winds up being a duplicate post, my apologies in advance.)
I typed about:synch-log into the address bar and got an exclamation point inside a triangle next to a boldfaced message that reads "The address isn't valid."
Below that, in a box:
The URL is not valid and cannot be loaded
Then a line then two bullet points
* Web address are usually written like http://www.example.com
* Make sure that you're using forward slashes (i.e. /)

How can I get the Firefox browser to work with my high speed internet?

After switching from dial-up to high speed internet, I can no longer open the Firefox browser (which I was using) even after downloading the latest version. It is set for my default, but I can only use IE to browse. What else do I need to do to make it work?

You didn't tell me it was a user name password issue.
Open Keychain Access. (Applications/Utilities)
Select Passwords on the left.
Delete the Delta keychain.
Now from your Safari menu bar click Safari / Preferences then select the Autofill tab. Make sure: User names and passwords is selected.
Navigate to the Delta site. Login with your user name and password. You should be prompted to save that info to a new keychain.

How do I add the Firefox icon to my mac os 10.4.11 tool bar?

I just upgraded to firefox 4 and the icon disappeared from the toolbar on my mac screen. How do I get it back?

How can I fix my Firefox browser so that PDF files from the Internet do not blur and go out of focus?

When I try to open a PDF document from the Internet, it opens, with sharp resolution; however, within a few seconds, it blurs and seems to have multiple copies being shown on top of each other (ever so slightly mis-aligned). Yet, when I use any other browser, the document opens without losing sharpness.
Also, opening a saved PDF document in Adobe Reader does not cause any loss of sharpness.
Running updated Windows XP; Adobe Reader updated; and Firefox updated.

Firefox's built-in PDF viewer overlays a transparent layer of text over a graphical image so you can copy/paste. It doesn't always line up pixel-perfectly, so if the text is not transparent for some reason, you will see double text.
Could you try switching to the Adobe Acrobat plugin? This article has the steps: [[How to disable the built-in PDF viewer and use another viewer]]. Does that one work correctly?

How to transfer safari to firefox browser

How do I set the Firefox browser (when I click top-left) to English, rather than Dutch (not webpages)?

When I click the Firefox Icon in the top-left corner, when my browser is open, all text in there is in Dutch. However, I want it to be in English. I've searched for a solution, but could not find one. I was directed to Options > Content, and then going to the bottom of that page to adjust my language preferences, but this does not solve my problem. To make it more clear, I've linked a screenshot of the situation. All the Dutch text in there, I wish to be in English.

Thank you for your time.

hello, please download an english language version from https://www.mozilla.org/firefox/all.html - just install it on top of your current installation, all your bookmarks, settings & customizations will be kept!
