How do I extend the depth of the links in the "back" button?

I needed to access the initial webpage URL of a site I was exploring. I had hundreds of URLs from this site and could not find the link in my history.
I naturally used the "back" button, but realized it only went back 10 links. Is there a way to increase the number of links shown, under Foxy's advanced options?

You should be able to go back 50 pages.
You can modify the value of this pref on the <b>about:config</b> page:
*browser.sessionhistory.max_entries = 50 (default)
You can open the <b>about:config</b> page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

Note that session restore only stores a limited amount of page.
*resource:///defaults/pref/firefox.js
<pre><nowiki>// number of back button session history entries to restore (-1 = all of them)
pref("browser.sessionstore.max_serialize_back", 10);
// number of forward button session history entries to restore (-1 = all of them)
pref("browser.sessionstore.max_serialize_forward", -1);</nowiki></pre>

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration 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
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")
Another possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

How do I get the Back Button drop down menu back?

When surfing in a tab there used to be a drop down menu next to the forward and back buttons. It was a little tiny triangle looking arrow. This was really useful and needed. It is gone in Firefox 4 as far as I can see. I am using the default 4.0 Theme. If it is not there anymore I will have to go going back to 3.16 if the drop down menu is gone. Thanks for any help.

I do prefer Right-click on tab for tab history, or hold a couple of seconds, as the drop-down marker takes up space and had been removing it myself. Although I think it should have been an option.

How do i get the back button on my android device to function right?

How do i get the back button to got back to the previous screnn I was on?

I usually use a code such as...

     e.preventDefault();
     if(options_mc.visible == true){

Good to hear, Tom. Did you use "Customize" from the View Menu?

How do I get the back button in Safari to work again?

The back button stopped working. I can only refresh the page. To go back I need to go up to History, and click back. I loved it when the back button worked. Any suggestions? I have a MACBook and Leopard

For any of you who have had this problem... here is the real solution. On the upper task bar, Go to VIEW, open up CUSTOMIZE TOOL BAR, find the FORWARD AND BACK ARROWS and DRAG THEM UP TO WHERE THEY BELONG. How did they disappear?..... some accidental combination of keystrokes deleted them, I don't remember what that was. End of story and I am sticking to it

After my update to version 4, the back button now only seems to store the last page I was on rather than the last 10 like it used to before the update. I've scoured the options menu to no avail. How can I get the back button working like it used to?

The back button used to work many times before it would reach the end of its list of pages I had been to recently and became greyed out, but now it will only work once before this happens. Also, the list of pages that pops up when I right click it now only has two entries no matter how many pages I've visited on that tab, the page I am currently on and the page I most recently left. Previous to the installation of the update to version 4 however, the list that appeared when I right clicked on the back button contained up to 10 items.

Try the Firefox SafeMode. <br />
''A troubleshooting mode, which disables most other Add-ons.''
# You can open the Firefox 4.0 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
# Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

ALV: OOPS: How to identify when the BACK button is hit?

Hi All,
I have a requirement in which when the BACK button on the ALV output is hit, i have to leave to the Original Selection Screen.
I know that using SET SCREEN 0. this can be done. But i'm unable to find the point at which the Event about the BACK button is triggered.
How can i identify if the button hit was the back button?
Thanks in advance,
Jr.

Hi Jr,
u declare sy-ucomm in data decla.
in code try this out.
Case sy-ucomm.
when 'BACK'.
leave to screen#. " # For the selection screen (i dnt think it is 0).
u obviously have to set the PF status for the same by SE41 and in Aplication, u give name as BACK for the back symbol.
I hope is will help.
Reward if useful
Thanks
Sujay

How do I use the back button to go back more than 1 step?

In previous versions of Firefox and common in other browsers is a small pull-down option on the back button that will allow the user to go back more than 1 step in browsing history.
Typically, the pulldown will show a chronological list of recent sites visited and the user could select one. Firefox 4 seems to have dropped that feature and you can only click it to go back 1 step at a time. I really miss that feature.
Is there a way to enable or add on the ability to go back more than one without having to go to history?

You can get the drop down list by either right-clicking on the back/forward buttons, or holding down the left button until the list appears.
If you want the drop-down arrow you can add it with the Back/forward dropmarker add-on - https://addons.mozilla.org/firefox/addon/backforward-dropmarker

How do I replace the back button which was there befor that new clock thing is too much troble just to go back a page I guse thats the end of firefox for me

How do I get the old version of firefox back
so I can quickly look at the last page not have to click on a half dozen clicks just to go back 1 page

The arrow to open the tab history of the Back and Forward buttons has been removed in Firefox 4 and later.
Use one of these methods to open the tab history list:
* Right click on the Back or Forward button
* Hold down the left mouse button on the enabled Back or Forward button until the list opens
You can look at this extension:

How do I restore the "back" button/arrow to my browser?

My back arrow/button has magically disappeared from my browser. How do I bring it back?
I have already deleted and restored mozilla.

If the menu bar is hidden then press the F10 key or hold down the Alt key to make the menu bar appear.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible:
*"View > Toolbars"
Open the Customize window to set which toolbar items to display:
*View > Toolbars > Customize
*Firefox > Options > Toolbar Layout
*Check that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
*If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette in the customize window to the Bookmarks Toolbar
*If missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
*If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up
You can check for problems with the localstore.rdf file if this didn't fix it.

How to get the back button if we to go the 2nd drill down report??

Hi,
I have a drill down report for the main report. And have detailed drill down as in 1st report>2nd report>3rd report.
But once i goto drill down, the return button is there which directs to main report i.e. 2>1,
But once i goto 3rd, i do not get the back button so that i can access reports in 3>2>1, instead its going directly to 1st from 3rd.
hope i have made the point clear.
Someone suggest me how do i get the back button??
Thanks!!

use the below code in Narrative view
<script>
function goBack()
window.history.back()
</script>
<input type="button" value="Back" onclick="goBack()">
If helps mark

How do i extend the bandwidth of my system

The control problem I am having is extending the bandwidth of a force control system. The system is used to apply mechanical load to bone to facilitate research into Osteoporosis. The following concisely describes the system and the different things I have tried to solve the problem,. I imagine it is quite lengthy compared to the usual questions but any advice you have to offer to a Mechanical engineer would be much appreciated.
System Description:
I am using Labview (with Flex motion) to program the NI 7344 motion control servo board (PID update rate of 62.4 micro-seconds). This output signal is then amplified by the MID 7654 power amplifier, supplying current to a Voice coil (this can be considered as a Linear DC motor with a bandwidth of 40Hz). This applies the force to a bone sample. Feedback is then provided by a load cell and connected to the ADC feedback channel of the servo board. (For full specs of all mentioned components please refer to the web links which are listed at the end of this email!)
Problem description:
After optimally tuning the PID characteristics and defining the amplitude and pre-load, I can successfully control a continuous, sinusoidally varying force (frequency 1Hz), however when I try to increase the frequency to 10Hz, the amplitude of the output waveform is marginally reduced�i.e. there is attenuation. I know that the bone sample is not viscoelastic enough to act as a low pass filter. The bandwidth of the Voice coil is not a limiting factor either, so�..
How do I extend the bandwidth of this system?
The following Paragraph describes some of the things I have tried, which have had some or no influence. Being a mechanical engineer I would be grateful for any expert advice.
(Note all results have been verified with an oscilloscope where applicable)
Influential Factors:
1) Method of programming.
To generate the wave form a series of points describing one period are written to a circular buffer on the servo board. The points are executed in 10 milli-second intervals and are splined through using a cubic spline algorithm (hence a period described by 100 points gives us a frequency of 1Hz and a 10 point wave gives us 10Hz). All this happens on the servo board in real time. I am confident that although the integrity of the sine wave is reduced at 10 Hz the amplitude is still described within the 10 points and so is not the reason for attenuation. However this does limit the maximum frequency achievable. (I would say the max frequency is about 20Hz)
2) Redefining the resolution of the of the ADC Feedback
The 12 bit ADC feedback channel is scanned at a rate of 50 micro seconds (faster than the loop update rate which is 62.4 micro-seconds). Initially the voltage range was specified at -/+ 10 V giving 20/(2^12) Volts per significant bit, however I noticed that when I increased the resolution to the max possible by changing the range to 0-5 V (giving 5/(2^12) volts per significant bit), the amount of attenuation was reduced, however there was still some attenuation there. This begs another question why would this factor improve the frequency response???
3) PID characteristics
The system gives an optimum step response when using only a pure integral term and setting Kp= 0, Kd= 0. It seems as though the fastest step response is limited to about 6 milli-seconds. The system is fine tuned and any slight increase in the integral term results in immediate instability. Therefore there is no scope to improve the system bandwidth by altering the PID characteristics.
Can you offer me any expert advice?
Considering this information, what would you advise? Do I need a board with a faster loop update rate ?, I have considered using Labview Real Time, which offers a board with a 26 KHz update rate as apposed to the 16Hz (62.4 micro-seconds) provided by the current board). Do I need to use different control algorithms as apposed to PID, if so which ones???
Any help or advice you have to offer would be much appreciated and could help in the battle against osteoporosis. Should you require more information or would like to speak to me send me an email and I can answer any further questions or give you a ring.

Hi Duncan,
i'm sorry that this answer took this long, but i think a constructive answer which takes a long time is better than a useless answer in a short time....
For the following thought-provoking impulses we have to consider the signal-change when increasing the frequency. The points which describe the signal get streched over the period. Increasing the frequency enlarges the distance between the points.
a) The spline algorithm could be the problem here hence the signal does not correctly pass through the points anymore with increased frequency. Therefor the amplitude decreases with increased frequency. Perharps another kind of spline algorithm can be helpful.
b) Another point can be the control deviation. Since a feedback control system needs a devia
tion for the control, the deviation gets larger when increasing the frequency of the controlled loop. Maybe the control loop has to set the desired value when already getting to a new point. So the signal could get "washy" and the maximum amplitude is reduced.
In this case, the "Velocity Feedforward"-parameter could be of use. This parameter is to use with caution for it can have similar effects like a too high chosen integral term.
c) You can try to set the 7344 to circular contour. Therefor use 2 axis where you use the second axis as dummy (open step). There is a major disadvantage in this setup: since you use 2 axes at the same time, the 7344 can update each axis only with 125 microseconds. But perharps this is sufficient. Either way the parameter of the control loop have to be adapted (integral term reduced).
d) If the 125 microseconds describend in c) is insufficient, you can try to test it with a 7352. The 7352 can handle 2 axis at a time with a update rate of 62.5 microse
conds for each axis.
I hope this answer helps you in solving your rather special issue.

How do you extend the guest network on a time capsule to an apple express?

I have a time capsule in my main house with a password protected guest network i set up an apple express in the guest house to extend the networks. Unfortunately the guest house / apple express is only amplifying the main house network. I would like my tenant to join the guest network from apple express. Is that possible?
