 opera-usb Admin / Miraculix: Opera Portable has the same Problem when it crashes - ALL Data will left on the PC.
Opera-USB but the TempDir to Harddisk to Save Lifetime of the USB-Stick/Pen - It's also possible to let TempDir on the Stick/Pen
OperaUSB make NO RegEntrys ! [2006-06-29 22:51]

 Douglas McFadzean: Whilst Opera can indeed be made portable, I feel that maybe it should come with a "health warning". The problem is that Opera always caches files to a read/write disk, even if you set the disk cache to zero. To save flash drive I/O, OperaUSB directs the Opera cache to a temporary folder in the user profile folder. It also enables an Opera setting that tells it to automatically delete the cache files on exiting. However, if Opera crashes, someone using a simple undeleting utility like Restoration could uncover your cache files and the privacy of your browsing trail is severely compromised. This is unlike portable K-Meleon or Firefox which (if you zero the disk cache) will never write files to the hard drive. I think your readers need to know about this in case they are lulled into a false sense of security by the writeup "OperaUSB ... does not write to the registry nor leave any data on the guest machine where it is run." True on one level, but not if it crashes. [2006-07-05 00:37]

 Patman: It looks pretty good, however good luck with the e-mail. I spent an hour trying to figure out how to send mail. Theres a compose buttong, a window opens with no "TO" or "Subject" or any fields to fill in. I deleted the entire blasted program. [2007-03-07 21:15]

 Miraculix / Admin of Opera-USB.com: The EmailClient also work without problems ! for help visit http://my.opera.com/opera-usb/forums/

Opera@USB has no virus ! look at the Downloadawards! [2007-03-14 23:38]

 Bruno: Perfectly! fast, with mouse gestures and tiny. portable firefox is dead ;) [2007-04-06 23:25]

 tripex: FirefoxPortable seems to be more secure against privacy.
And BTW the Mouse Gestures Add-On works well. Furthermore I still have one or two killer add-on which prevents me to change to OperaPortable, Foxmarks and Adblock Plus. [2007-04-23 19:56]

 Stephen Adams: I found it does not work without Pstart.exe running it as it tries to load in from the root directory, no matter what directory you start it in on the USB.
Substitute drives program (from portable apps) does not work with opera! [2007-05-09 11:55]

 Gary: Douglas (above) has already mentioned it, but this 'portable' version of Opera writes a cache to a user's Local Settings\Temp directory, even if Opera's cache is set to zero. These files are easily recovered. [2007-05-23 19:03]

 Rasczak101: By default this version does write the cache to the user's Temp directory, but this can be changed.
Once running on a safe PC, type opera:config in the address bar and hit enter. Go to the User Prefs section and set the following, be sure to include the full stops before the backslash
Cache Directory4 - .\profile\cache4\
Operator Cache Directory4 - .\profile\opcache\
Temporary Download Directory - .\profile\cache4\temporary_download\

Hit Save

These then set the cache to be written to the install folder of OperaUSB. [2007-06-01 02:10]

 DG: I HIGHLY suggest everyone to try Opera Portable ( www.kejut.com/operaportable ) as I've been using it for months and have been completly satisfied. Web Browser, RSS feeds reader, Email client, IRC client, Instant Messenger (AOL, Yahoo, MSN, etc.) all in a file that weights in under 5 megs. [2007-06-07 09:58]

 MiDoJo: "I found it does not work without Pstart.exe running it as it tries to load in from the root directory, no matter what directory you start it in on the USB.
Substitute drives program (from portable apps) does not work with opera"

I have NOT found this to be true, Be sure that Pstart is pointing to "operausb.exe"

Please Note that if you are updating the version of OperaUSB on your drive that there is an updater on the Website (instead of clear and load) [2007-08-22 12:16]

 Chip McCann: The following registry entry is left on my machine:

HKEY_CURRENT_USER\Software\Opera Software [2007-08-26 16:47]

 Grunt: Opera Portable is better than Opera USB. If it crashes, nothing is left on the harddrives. But I'm not sure if it's stealth, though. [2007-11-22 02:27]

 Selvam: I agree, Opera is miles ahead of rest of pack. There is one snagging inconvenience though.
While FF and IE could easily configure across my office proxy servers, Opera is aksing to provide proxy server user/password.
Any answers? [2008-03-04 19:54]

 j_sk: @ Selvam - Yes! Just provide'em...
@ Grrunt - You just cannot say "Opera Portable is better than OperaUSB". That's a non-sense opinion! How do you manage to crash 9.26 ver when OpUSB 9.50 beta last build is yet difficult to crash? Put your Op caches on your stick, in case, you won't have data left behind you on guest machine. [2008-03-06 05:43]

 Kermode: j_sk:
Of course he can say that! And he gave one reason. Who are you working for? [2008-03-07 06:57]

 Selvam: @j_sk - If only I had them! Don't you think so?
With firefox I just give the proxy name and port, if it works there, why NOT in OPERA? That's simple? [2008-03-12 00:45]

 T-Wood: Opera USB Takes forever to load and is very large to put on any Flash Drive, I use Opera Portable on Kejut, it runs faster deletes personal data on the HDD when it closes. Way better (I'm using it as I type) [2008-04-01 14:03]

 MiDoJo: Howdy OperaUSB 9.27 is up and running. If you already have OperaUSB go to Website (From this download) and use the updater zip. Otherwise Andrew you need to update the download here. This update fixes a multiple security flaw. This is especially important for me because I use Opera as a text only browser for malcious or possible malicious sites. [2008-04-11 14:24]

 Carbonize: As a web developer/designer I need to test my work in as many browsers as possible and portable versions make that so much easier.

@MiDoJo - I personally use Firefox for viewing all sites but especially ones I suspect of being malicious.

@Selvam - Because in my experience Opera never makes anything easy. On Firefox I have cookies disabled and have manually set what sites can store cookies. It was easy on Firefox and logical but try doing it on Opera.

@Selvam - How the heck is Opera miles ahead of the rest of 'the pack'? [2008-06-02 03:42]

 anonymous: Apart from 9.2 series there is also 9.5 series Opera USB (but they are beta)

 Portable Paul: Man i dig this browser. The look and feel is so nice.
It renders pages really fast.
Uses cache for 'back' operations.
Highly configurable skins and toolbars. [2008-06-30 11:34]

 Portable Paul: One major drawback. It does writeback to your flash drive pretty often, at least once per page. Causing a 1-2 program hang while it's doing it. (My flash drive is one of the fastest available so drive speed isn't the issue.voyagerGT 8gb)I think i'm switching over to kejut's version but i wish opera@usb would just figure out how to fix their version. [2008-07-08 23:55]

 RandomTask: I would not be too trusty. It appears that upon start, Opera checks - aside from the usual update- and news-sites - on the following websites:

fh-in-f101.google.com
fh-in-f102.google.com
fx-in-f104.google.com
fx-in-f147.google.com
nf-in-f99.google.com
nf-in-f147.google.com

210-11.amazon.com

fe-us.answers.search.vip.re3.yahoo.com

www.answers.com

www.ftjcfx.com which directs to www.cj.com/qksrv.html

I think the first six and the last one speak for themself.
I will stop using Opera. [2008-07-19 16:35]

 xeraf: it is great software, have great feature and easy to use. you must try [2008-08-05 23:40]

 flyerfly: It hung a couple of times on my PC running Windows XP. Size is 3 times of similar program, such as Opera Portable. I personally like Opera Portable [2008-08-09 01:54]

 ladymitch: what's the different between opera portable and opera usb??? [2008-08-17 17:07]

 Arik: @ladymitch that's like asking 'whats the difference between a penis and vagina.' not much. [2008-09-08 20:58]

 Grandy Johnson: Arik...I'm sorry to hear about your inability to identify specific differences between a penis and a vagina. You are either very lonely and uninformed, or through some tragic accident have lost your eyesight and damaged all sensory receptors--including the ability to smell and taste.

As it relates to the difference between Opera Portable and Opera USB, Opera portable address the whole issue of "erasing your tracks" by temporarily storing working files on the host computer then erasing them when you close the browser. Part of the reasoning behind this is to prevent excesive wear and tear of the flash drive through constant reading and writing. This also means that if the power goes out or you pull the USB drive out before closing Opera Portable, the files remain behind you on the host computer. Finally, if you have a lot of files that you've work with and a lot of places on the Internet you've visited, the cleanup/erasing routine after you log off Opera Portable can take a long time. [2008-09-09 12:30]

 Nightwaker: There is one feature that to me stands out more than any other. Naturally, having mail, chat, mouse gestures, voice command(!), RSS and all the other goodies in one neat package is great. Then you have the sync-function. I have the same bookmarks and speed dial at home, at work, or what ever computer I plug my thumbdrive into, and I love that. Oh - also on my phone, with Opera Mobile! [2008-10-14 15:41]

 Portable Paul: Months later i'm completely addicted to operaUSB. I have a dozen custom searches which are fantastic time savers. Adblock is easy with the urlfilter.ini updates that are easy to find on the intarwebs. Built in sync of all those features across all instances is wonderful. Sadly what really started me looking at it was the really unique skins that make it much more easy on the eyes than the other browsers... one last huge benefit: for web research, the back button restores previous pages using file cache so it's instant. The speed difference between opera and IE is immense. I love opera, it's easy to customize and just screams. [2009-01-18 15:39]

 Mazzinga: It is great software, simply the best web browser [2009-03-16 10:56]

 Tex_Son: I love this browser because it is FAST on startup and loading pages. Much faster than Firefox portable and Opera portable. I've only been useing it for about 2-3 days and have used it on 2 different computers. I have found out that my history, bookmarks, and skins are different on the 2 machines. How do I change this? This means that a trail is left behind which defeats the purpose of running it off a usb drive. One last thing, the only thing missing is a calendar/PIM part which would make it a liveable travel solotution to Outlook on the road. [2009-03-22 12:10]

 Opera:config: Hi, Rasczak101. Thanks for the info about the cache setting. I tried it and it seems to work so far. However, after this change, I can't open opera:config.. How can I solve this problem? Can anyone help me?? [2009-04-04 04:54]

 Andrey: OperaUSB V9.64 works VERY SLOWLY on my Pentium 4 3,0GHz/1GB computer. It often lags, though I run it from my local SATA disk. I delete it just now! [2009-04-14 12:10]

 Long.Knight: I like Opera Portable (http://www.kejut.com/operaportable) wonder why it isn't in the list...

But then I'm just another

 Mike: OperaUSB came in handy one time when I was trying to access the web through Internet Explorer, which took forever to load a web site. Then I used Opera and the web site loaded much faster. Still not sure why Internet Explorer had serious problems that day but I'm convinced it's a good idea to have an alternate web browser like OperaUSB handy for situations like these. [2009-08-20 17:36]

 Ratatosk: Was looking forward to this - but the wait put me off. This is a very slow app for something that should be portable. [2009-09-20 15:49]

 Boongo: Not private; leaves traces behind!

Beyond that, not bad. [2009-10-23 00:29]

 KingMudkip: I hate this program. I decide to delete it to reclaim the space on a secondary drive, and the profile directory just won't die! Every time I try to delete it, Windows says "Cannot remove folder mail; the directory is not empty." But every time I delete the file in the mail dir, IT COMES BACK! Please help me get this @#%! off my drive! [2009-11-17 16:02]
