Tweaking Firefox or Mozilla

 

Easy Firefox and Mozilla Tweaking! 

bulletType " about:config" into the address bar and hit return. Scroll down and look for the following entries :

network.http.pipelining network.http.proxy.pipelining network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

 
bulletAlter the entries as follows:

Set " network.http.pipelining" to "true"

Set " network.http.proxy.pipelining" to "true"

Copy and paste in find field (network.http.pipelining.maxrequests )

Set " network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

Lastly right-click anywhere and select New-> Integer. Name it (copy and paste)" nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it recieves.

Exit Fire Fox and restart.

 

Firefox Hacks


 

Modify Tabbed Browsing:


 

Tabbed browsing is often touted as one of Firefox's killer features. Indeed, it's very useful, but the default preferences aren't perfect for everyone. That's OK, because Firefox offers plenty of preferences for customizing your tabbed-browsing experience. If you can't find what you want in the preferences, you can go a step further by installing one of the many Firefox extensions that can make minor alterations to your tabs. Still not satisfied? The most aggressive of all the tab-related extensions, discussed at the end of this hack, completely replaces Firefox's tabs with its own.


Tabbed-browsing preferences:


Firefox's preferences allow you to control how tabs respond to certain types of events. Some of the preferences are easily set in the Preferences window, while others require you to use the special About:config page in the browser. To find tabbed-browsing preferences in About:config, type tabs in the Search box at the top of the list.

Links from other applications:

When a link is sent from another application, such as when you click a URL in an e-mail, what should the browser do? There are three options: open the page in a new window, open the page in a new tab in the front window, or replace the current page in the front window.

The options for this behavior are shown at the top of the Tabbed Browsing panel in the Preferences window. If you ever feel the need to set this preference via About:config, look for browser.link.open_external. Setting this preference to 1 opens the link in the current tab and window, 2 opens it in a new window, and 3 opens it in a new tab in the front window.

Loading tabs in the foreground or background:

There are three preferences that control whether new tabs load in front of the current tab or behind it. These preferences correspond to the three types of events that can open a new tab. Two can be set in the Preferences window (checked or true means "load in foreground"; unchecked or false means "load in background"), while the third requires the About:config page, described earlier in this hack:

bullet

Control-clicking (or Command-clicking) a link in the browser to open a new tab
Set this in the Preferences window with the check box labeled "Select new tabs opened from links" or in About:config by changing browser.tabs.loadInBackground.

bullet

Opening a tab from a bookmark or the browser history panel
In the Preferences window, this event is called "Select new tabs opened from bookmarks or history." In About:config, it's browser.tabs.opentabfor.bookmarks.

bullet

Opening a tab from a link sent by another application
There is no check box in the Preferences window for this setting. In About:config, this preference is browser.tabs.loadDivertedInBackground
.

bullet

Getting rid of tabs when there's only one
This preference hides the tab bar at the top of the set of tabs when only one tab exists:

browser.tabs.autoHide /* set to true to enable hiding */

bullet

Single Window mode
Do you hate it when links on Web pages open new windows (because they set a target attribute on the link)? You can force Firefox to open those links in a new tab instead of a new window. This is called Single Window mode. It doesn't prevent all new windows, but it catches most of them. The radio buttons for setting this preference are in the Preferences window, but only if Firefox knows you want to see them. Go to About:config and set browser.tabs.showSingleWindowModePrefs to true.

Extensions that alter tabbed browsing:
There are a number of Firefox extensions that interact with tabbed browsing. Two are designed to make it easier to set the preferences exactly as you like, and one adds some useful new features via the creative use of tabs and keystrokes. New extensions are being written all the time, so check the Mozilla Updates Web site for the latest additions.

bullet

Tabbrowser Preferences
The Tabbrowser Preferences (TBP) extension, by Bradley Chapman, organizes all of the preferences related to tabbed browsing into a single pane in the Preferences window. You can set all of the same preferences via the special About:config page, but by using TBP, you don't have to remember what the different preference names mean or what value to set in order to get the behavior you want.

bullet

Quick Tab Pref Toggle
The Quick Tab Pref Toggle (QTPT) extension, by Jed Brown, allows you to maintain two sets of tabbed-browsing preferences. The idea is that you'll usually want to divert all new windows into new tabs, but occasionally you'll work with a page that really should pop up a separate window. This extension lets you put a small button (a toggle) in the toolbar to flip back and forth between two sets of preferences with a single click.

bullet

Magpie
Magpie, by lead Firefox developer Ben Goodger, is not a tabbed-browsing extension per se, but it has a related feature that demonstrates a completely different use for tabs. Magpie can save all of the tabs to the right of the one you're currently viewing to files on disk. (It's intended for media files, such as pictures.) For example, if you open a photo album Web page that contains thumbnails of a dozen pictures, you could Control-click (Command-click) each of them to open the full-size photos in separate tabs. Then, a single use of Magpie's Ctrl+Shift+S would save all of those images to disk in a single folder and close the tabs. This is much faster than saving each image to disk one at a time.

Tabbrowser Extension: a complete tabbing overhaul
The Tabbrowser Extension (TBE), by Shimoda "Piro" Hiroshi, is a power user's tool. It's the superultradeluxe tabbing system, with every feature you can imagine and a few you probably can't. TBE completely replaces the built-in browser tabs with TBE's own. Review the install notes and latest status, as TBE is still being polished and debugged as this goes to print.

TBE's tabs look just like the regular tabs in Firefox (by default, anyway) but offer lots of features you simply can't get any other way. In fact, TBE is so flexible that the Preferences window for tweaking its behavior has almost as many options as Firefox's own Preferences window! TBE allows you to do the following things:

bullet

Rearrange tabs by dragging them to the left or right

bullet

Duplicate tabs in the same window or into a new window

bullet

Color your tabs

bullet

Display tabs on any side of the browser window (not just the top)

bullet

Automatically load the same group of tabs you were using when you last quit Firefox

bullet

Undo a closed tab (reopen it to the same page)

bullet

Lock a tab so that all links within it automatically open in a new tab

bullet

Block the page in a specific tab from being listed in the Referer: header when you click a link

bullet

Automatically reload a tab every n seconds, minutes, or days

bullet

Add a Close button to every tab

Use keyboard shortcuts:

This hack shows you which keyboard moves come standard with Firefox. There are many extensions that modify the available set of keystrokes and key chords.

Many Firefox keyboard combinations are the same as those of Internet Explorer. In particular, menu navigation uses the same combinations of arrow keys and Alt as most Windows applications, and navigation within text-editing fields supports the same keystrokes as most text editors (Ctrl+Left Arrow to move one word left, for example). Scrolling keys such as Page Up and Page Down work as you'd expect, too. The table below shows the major keys used by both browsers. (On the Macintosh, substitute Command for Ctrl and Option for Alt.)

Make Firefox go fast


 

Here are a few steps you can perform to speed up Firefox. Back to performance basics first, though: the user is the slowest thing attached to the computer. Better use of Firefox's features will speed up the user, so be sure to read the rest of the hacks in this chapter.

Fix dial-up modem bottlenecks
Any dial-up modem you use is the slowest network hardware you have, so tune it wisely. Make sure any modem connection is running as close as possible to the maximum speed for POTS (plain old telephone system) phone lines. That line is usually a 64Kbps service (unless you're stuck on an ancient analog exchange). No one gets every drop of 64Kbps out of it, unless they pay a fortune for ISDN, but you should get 53.3Kbps at least.

If you're using Windows, your modem driver and chipset should support the latest compression standards now available. Update the modem and the modem's Windows driver directly from the chipset manufacturer. Look on the modem card to see who made the chips; don't bother with who made the card. If you buy a cutoff switch that lets you isolate your answering machine, fax, and telephone gear while you're on the Internet, you won't strain the line voltage as much, and you'll have less noise causing error-correction delays.

If your connection is still slow, call your telephone provider and complain that their voltages and noise filters are all wrong; they can test and adjust from their end. Call Microsoft and complain that Windows hasn't tuned your PPP connection correctly. Call your ISP and complain that their modem bank isn't negotiating the best possible speed. None of that will do you much good, but it's nice to vent sometimes.

Move to broadband
If you're stuck on dial-up, the biggest performance plus you can get from Firefox without using caching is to turn images off. That's in the Options dialog box under Web Features. Turning off images might reduce your Web experience to an unacceptable low, so it's a dramatic step. You can also ensure that Web pages are checked for updates only once per browsing session, instead of every time you look at them. In About:config, find:

browser.cache.check_doc_frequency /* set it to 0, normally 3 */

This preference change shouldn't affect you much if you're just surfing idly. If you spend a lot of time with online message boards or similarly intensive Web-based applications, it might cause confusion, though, so avoid it in that case. One possible compromise is to create a separate "I'm not working" profile and turn the preference on in that profile. Use that profile for recreation only.

Some of the Firefox ad-blocking extensions prevent advertising images from being downloaded, which is a further performance-saving feature.
