Lost Tabs in Channels palette

Hey Folks...
Newbie here learning my way in Photoshop. Any help is appreciated.
Using Photoshop CS3... When I pull up the Channels palette I seem to be missing the "paths" and the "layers" tabs...The only tab i see is the Channels tab.
I remember seeing them and then i think i deleted them by accident....
Any ideas?
Thank u!!

Thank u!! Figured it out. Opened Layers palette and dragged channels tab into it.

How do I recover my lost tabs after updating to Firefox v33?

Problem: After update to v33, I am unable to restore my lost tabs and GROUP tabs from my previous session, which was last night at 6:38 pm EST.
Here are the steps that I have taken:
1) History > Restore previous session is greyed out.
2) I have checked to make sure that I had configured session restore by going to Options > General panel > When Firefox starts: > Show my windows and tabs from last time.
3) I have right-clicked on Firefox > Properties > Previous Versions. But since I never set up any sort of restore configuration, there were no previous versions available.
4) I have tried to look for the sessionstore.js file in my profile folder to replace it with my sessionstore.bak file because the date for that file was last modified at 10/14/2014 6:38pm. However, I can not find the session.js file and the only sessionstore-related files that I see are: session.rdf, sessionCheckpoints.json, sessionstore.bak, sessionstore.bak-20140923175406.
Please help! I had a lot of tabs. I don't want to go to History to find my tabs one by one because I also had GROUPs of tabs that I have not opened in a month or more and each group of tabs have many tabs in them too.

Hi magasx, I'm trying to understand the part about previous.js. That was not helpful because it wasn't an early enough version of your session? In your screenshot it is a very large file, and so is your recovery.js. Did you check the list of closed windows and tabs that appears on the History menu to see whether what you're missing appears there?
Your screen shot shows a 9MB file from March 22nd, it's the last one in the list. To try that file, I suggest copying it to a safe place, and then when Firefox is closed, renaming the current sessionstore.js file to sessionstore.old and copying in the upgrade...js file and renaming it to sessionstore.js. Then when you start Firefox, Restore Previous Session. Does that get you close?

How do I recover lost tabs when Session Restore and the option to load previously closed tabs aren't available?

Hi there,
I have been having a hell of a time over the last couple days days to recover my lost tabs in Firefox, which vanished yesterday morning (Restore Previous Session and Restore Closed Tabs were both greyed out). Actually, my add-ons have also been removed and many of my settings seem to have reverted back to their default state.
My default setting was to show my windows and tabs from last time, but I recently updated Advanced System Care, and it seems that its AutoClean feature (which sweeps cookies, surfing history, cookies, browser cache, etc. at startup) removed all of this. I'm pretty sure this was the culprit, anyway - curiously my history seems to have not been deleted. But I did get a notification after I booted that AutoClean had run and done its thing.
I had a lot of tabs open, which I realize is not necessarily a best practice, that had some important information on them. Sifting through my browsing history to find all of the important tabs I had open would probably take weeks and isn't really an option at this point. Also, my tabs didn't open until they were clicked, so I wouldn't be able to just look at the history over the last few days (since some of them were originally opened quite a while ago and haven't been clicked since).
I would tremendously appreciate any assistance that anyone could provide in recovering these tabs or a previous day's session/state. I have done a lot of reading so far but haven't been able to find an answer that works. If someone has one, that would make me extremely happy. I am using Windows 7 64 bit.
Thank you for reading,
Brian

You you no longer have access to that previous session via the sessionstore.js file, but still have the history then you need to check the history and use one of the sort options like sort by visited date to see which pages have been visited during that time period.
You can try to restore a previous version of the sessionstore.js file.
*Right-click: Properties > Previous Versions

How do I find the channels palette in PSE 8?

Hello,
I am using Photoshop Editor 8 and attempting to create retro-style/technicolor images using the channels palette and creating greyscale images having gone through red, green and blue filters, and then colorise them (As seen here: http://www.youtube.com/watch?v=wJQj2ykF7fs) . How can I find the channels palette?
Thank you for your help!

Elements doesn't do channels. That video must be about Photoshop. However, you can add a channels panel to PSE using either Grant's Tools (free):
http://www.cavesofice.org/~grant/Challenge/Tools/index.html
or Elements+ from simplephotoshop.com (inexpensive, does more other things than Grant's tools).

How do I restore my lost tabs, when I'm synchornising every day?

Hi,
As I had some problems with FFox crashing unexpectedly I tried a solution, where I had to disable all my addons, restart FireFox and enable them again. But as I've done this and wanted to "Restore Previous Session" all what I got from restoring was the add-on's set-up.
So my question is: When I synchronize every day, how can I make a use of it? Is it possible to restore all my lost tabs?

Did you check for History > Recently Closed Tabs/Windows ?
You need to place sessionstore.js in the profile folder and thus have to rename sessionstore.bak to sessionstore.js
Firefox copies sessionstore.js to sessionstore.bak at the start of a session to make it possible to use "History > Restore Previous Session" to restore that session at any time.

Lost tabs and history after update-version 26 android

hello
My device samsung s4 just updated to firefox 26 and deleted all my opened tabs and all my history. there is no button to press in order to restore my tabs and in history I see only today's pages. I had 31 tabs which i dont remember and now I lost them.... what can I do?

Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.
check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar
* if "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette into 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 setup
You can check for problems caused by a corrupted localstore.rdf file.

How can I see the alpha channel in the channels palette?

Hello, mi format plugin loads a rgba image. I see it with transparency, that's ok, but when I go to the channels tab I only see 4 items (RGB, Red, Green and Blue).
How can I see the alpha channel of my file in the channel tab?
Thanks!

OK, something must be wrong... but I don't find it!
That's my whole code (resumed). I ommit some code (saving file code (not used) or main function, where I only call te "DoSomething" functions. You can see that I use layers. The DoReadContinue function is only used to show the preview.
In the DoReadStart function I set the parameters for the layers (and the preview), and I fill the "data" and "layerName" params in the DoReadLayerContinue function. I hope you can understand the code!

And that's the image that I obtain loading a 8 layer image:
The layers have transparency (when I set "transparencyPlane" to -1, or 0, or 1, or 2, or 3, or 4....., I got the same result!). The blending mode is still "normal". I had set it to "linear dodge" The "isVisible" param works OK.
Alpha 1 is still black.
Is possible that I need to set something in the .r file? I had to add "FormatLayerSupport { doesSupportFormatLayers }," to manage layers, for instance.

Firefox crashed while automatically downloadingthe latest version, and when I reopened it, it did not give me the option of restoring my lost tabs. Is there any way to recover them now?

I don't know what more details to offer. The browser crashed, all my open tabs were lost, and when I restarted Firefox, it did not give me the option of restoring the tabs. I really want them back. Is there any way to roll back and recover them?

That gripes me to no end, as well. You might think Mozilla could think this one through, at least to the point of realizing there should be a manual means to recover open tabs NOT restored automatically after a routine FireFox crash.
And if Mozilla cannot stabilize FireFox, it will keep losing users back to IE.
The epidemic of crashes seemed to begin when FireFox "improved" itself with the idea of running 3rd party plugins in a "container", which is still far from reliable. I must run SysInternals Process Explorer at least once per Windows session to keep FireFox from destroying itself.
Aside from FireFox being so unstable, Mozilla should show some concern for users and make the manual restore option very plain from the UI-- such as "RESTORE OPEN TABS LOST SINCE THE LAST (*&&!!! FIREFOX CRASH"
Presumably-- and that may presume too much-- Mozilla leaves the open tabs "log" in place during each update. If that record of open tabs remains untouched from update to update, then why does FireFox screw up, update after update, and routinely fail to recover all tabs?
You might think someone at Mozilla would realize something is wrong. I have let Mozilla "phone home" after each crash, and yet the problem continues.

Using Excel on new Mac. I lost tab within a file? Any way to find?

We are doing our taxes and using Excel on new Mac. We lost a tab within a file! Hours of work. Anyway to find this tab? Also, how to we find the trash to check in there? Thanks so much!

You should contact Microsoft for Mac Support and/or post in their forums.

Lost tabs, history and preferences after crash?

Hi --
My Macbook Air just crashed after it was complaining of running out of disk space. After restarting, it looks like I lost all of my open tabs, browsing history, and preferences in Safari. Is there any way to get those back?
Ramon

Hi Ramon
Seems the most important issue hand is the "running out of disk space" prompt. Have you resolved it by removing unnecessary files?
Relative to Safari, go to the HIstory Menu>Reopen all Windows from last session. See if that restores the tabs.

How to recover last session/lost tabs on Safari 5.0.5?

Okay so I own a Macbook Air, and I always charge it no matter what, it's always charging and it always has battery. I keep open LOTS of things such as text-edit, safari w/ tabs, and pages. So today after I closed it, (didn't turn it off or anything) I came back and hour later to find it turned off, I turned it on again. And it clearly still had 27% of battery left. And ALL of my WORK was GONE!! I got so frustrated, I read there's no way I can recover lost textedit stuff if I didn't save it, I don't really mind what happened to pages. But I had important stuff in textedit I'm trying to remember and jot down now, and I also had important tabs opened in Safari. Is there any way to recover these tabs from the previous session? I read you can go to History > Reopen tabs from last session. But I don't see that option anywhere, I can't right-click on History nor does History have a drop down option.... Please help! =\ I'm very frustrated... thanks.

well, it's meant to
" To have TextEdit automatically save (or “autosave”) a backup of documents while you’re working, choose how often you want to autosave from the “Autosave modified documents” pop-up menu below Autosaving. If TextEdit unexpectedly quits, it opens the backup copy of your document the next time you open TextEdit. "
If you'd previously saved it, there ought to be a filename (autosaved) file in the same folder as the saved one.
If never saved - look in
Home/Library/Autosave Information/

Lost Tabs after unwanted tool bar over wrote my tabs.

My new tab started to show adverts instead oft he normal nine thumbnails. This was after a file download which was obviously highjacked.
I managed to get the original new tab screen back by restoring the tool bars.
At that stage I had all my tabs showing.
I had problems getting bask to the original options and in the process I managed to loose all my tabs.
Firefox now only sees the current tabs and cannot find my old ones. I've tried all the relevant options in restoring recent tabs etc. but Firefox itself seems to have lost the old tabs for good.
Question.
Is there a possibility that the old tabs are held in an old file which might be able to be renamed to allow Firefox to recover the tabs?
If so the filename and folder of the old tabs and the filename and folder of that Firefox can access would be very much appreciated.

Additional information.
The missing tab https addresses are shown as selectable address options when trying to do an internet search in a new tab. So Firefox has them, they are just not linked to tabs.
A response would be much appreciated.
