I've been on the 12.0 beta channel, so when 12.0 came out, I got automatically bumped up to 13.0, and I'm really impressed with the *speed* improvements.

With FF 12.0, in Facebook, I was regularly getting these warnings that the page had become non-responsive because of a FB script taking too long. But that's all but disappeared with 13.0. Overall web pages just seem to load much faster. And I noticed this speed increase *before* I realized I'd been bumped up to 13.0, so I don't think this was a just a perceptual "placebo" effect. In fact, I was noticing and really enjoying the improved overall performance, and was wondering what had changed, and then I did an About Firefox to "check for updates" (as I often do when using a beta) and to my surprise, realized I was at now 13.0.

If this faster page loading is what having the new SPDY control always on, as apparently is in 13.0, then this change is huge for this user, because the page loading, overall, is so much faster. Even though I have 64 Firefox Add-ons installed, the speed of 13.0 now matches or is often better than either Safari or Chrome (on my machine) when those two memory hogs are loaded with Extensions. I'm really pleased. They may be still working out bugs with SPDY (and frankly, I don't know much about how it works, technically) but if it works as well as it apparently does in 13.0, I hope they switch it on all the time for 12.0 users. It seems to be a huge boost.

A final point. I've been rising the Firefox beta channel for over a year now (love that bleeding edge!), and Google Chrome's beta channel, too, and I have to say that Firefox has nothing on the rate of new versions with Chrome. Chrome seems to change darn near every night, and the release version changes are way, way more numerous too. Plus, they have this crazy system version numbering system, like version 18.0.1025.168 and a big change can be like to 18.0.2045.283 or some such! And at the same time, you can have Google Chrome 20.0.1115.1 Dev / 19.0.1084.36 Beta / 18.0.1025.165, for example......Firefox seems utterly conservative compared to how Google goes at version changes.

Anyway, 13.0 rocks, in terms of speed, and I think only one of two of my 64 Add-ons were incompatible...not bad! And I haven't had a single crash since release. I've never been happy with Firefox than I am right now, and I'm constantly testing the competitors.

I am a huge fan of DevonTechnolgies, and own DevontThink Pro, the hub and brain of my whole digital universe, and DevongAgent Pro, my brilliant research assistant. So, when I read the description of Devonsphere, I just bought it..with DevonTechnoogies, what could I lose for $4.00? -- except, well, $4.00. ;)

Anyway, I've had it for a few days, and I like it quite a bit, but hope they will keep developing and refining it. Like DTPro, it's uncanny in finding linkages between e-mails, web sites, docs, images etc. I'm still learning how to use it, but see lots of potential.

On my machine, a iMac with 4GB ram and 3.07 Ghz Intel Core 2 Duo, I find the program reasonably fast, except when it's indexing, and then, it can really hog the cpu for a while. Not inoperable, but I definitely feel the performance hit.

Unlike a previous reviewer here, I find that DevonSphere typically uses 150 to 350 mb of ram. The only time I've seen it go higher than that is when its indexing, then the "devonbot" can use 800 mb for a while, and then drops it all when done.) But in regular use, I've not had to go higher than 350 mb.

My Devonsphere database seems to be aroud 875 mb. I have a 3.07 Ghz Intel Core 2 Duo, and I find the program reasonably fast, except when it's indexing, and then, it can really hog the cpu for a while. Not inoperable, but I definitely feel the performance hit.

Unlike a previous reviewer here, I find that DevonSphere typically uses 150 to 350 mb of system ram, and I've not had to go higher than that. My DS database seems to be aroud 875 mb -- which does't seem so huge, to me, because as a science editor/writer, I have over 43,00writer images using 45 GB of disk space and over 36,000 PDFs, docs, etc. etc using 34 GB.

Devonsphere works well in Apple Mail and Safari and with desktop items. Devonsphere works well in Apple Mail, Safari and Chrome, but I wish it worked in Firefox and Picassa, too. I'm still trying it out, so I don't know what other programs it may or may not work with.

Overall, I'm pleased with the $4 I've spent, and hope that DT will continue to develop and broaden the programs it works with .

First of all...HUZZAH for bringing back the Sidebar! That's *the* feature that makes SafariStand a must-have for me, and without it, I just can't use Safari with horizontal tabs. (Same with Chrome.)

I love how I can toggle between the side tabs and Reading List. I was wondering how the developer was going to work that one out.

But, I do find that I cannot use Netflix with the sidebar enabled...when I do, I can't get any of the Netflix Instant Play controls to work...start and stop, full screen, etc. I've test half a dozen times, and each time I go to Netflix with the Sidebar on, the Instant Play controls don't work...if I go to Netflix with the sidebar turned off, then I can use the Instant Play controls. But, if I turn the side bar on while I'm playing Instant Play, then the Netflix controls don't work for me.

I don't know if this is true for others, but wanted to report this and see if others had this problem with NetFlix Instant Play.

Otherwise, I'm thrilled with this update and so glad to have back my beloved side tabs!

I haven't been using Chrome for a while -- being using Firefox Aurora 9 -- but every now and then I check out Chrome to see how it's developing, and to my horror, I can no longer make Chrome use vertical (side) tabs...I had a little Applescript that ran this:

do shell script "open -a '/Applications/Google Chrome.app' --args --enable-vertical-tabs"

as an app. Using that to start up Chrome, I could then control-click on a tab, and then select "Use Side Tabs" in the contextual pop-up menu.

The program still fires up Chrome, but when I control-click on a tap, there's no option to tell Chrome to use side-tabs. (I have come to understand that I could have set this, in the past, within the About:flags page)

In any event, I was wondering if anyone else was using side/vertical tabs in Chrome and if this has suddenly stopped working (or been removed).

No side-tabs is a total deal-killer for me. I regularly have 20-30-40 tabs open at once, and the horizontal tabs of Chrome are (to me) almost useless in terms of visibility/readability. I know I can "fix" this with a number of Extensions, but I really would miss real side tabs.

I hope this is just a temporary change from Google; if not, Chrome just isn't a browser I'll use very much. (I wish that someone would implement an extension for Chrome like Firefox's great Tree-Style Tabs add-on if Chrome decides to abandon the idea of side tabs.)

Appreciate any comments or suggestion!

Argue!! 7.0 has become such a regular crasher that it's become useless for me. I'm using Google Chrome, for now, but I miss my Firefox. Maybe it's something about my machine, but I've tried everthing -- all Add-ons turned off, total fresh reinstall. But, about every 15 to 20 minutes, she goes down, often just sitting in the background while I'm working in other programs. If I load up with two windows with 20 to 30 tabs in each window, the crashes are much more frequent. I'm going "About Firefox" regularly and getting the most recent updates, but nothing seems to fix this problem.

I'm so bummed. When Firefox is working, with all my beloved Add-ons, she sails but now I feel like I lost a trusted friend. I'll keep doing the updates...maybe whatever it is—assuming it is not my machine set-up (10.6.8 on an Intel iMac)—I hope its fixed soon!

After I download this (whether from MacUpdate or the developer's site) and double-click, I get the message, "You can't install the file "Delivery Status.wdgt' because its not a valid widget."

Anyone else having this problem?

Hmm, I've downloaded this three times, and tried to install, but it gets all the way to the end, past validation and writing files, and then just says the installation failed..but no explanation.

Anybody else able to install 2.4.2? I'm running OS 10.6.8 on a duo-core iMac.

Like to try this out, but it crashes every time I try to do a search with debug messages like these:

After installing Snow Leopard, all my third-party Services, including DTPro 2 beta have disappeared -- I read that this would happen.

Alas, I can't seem to reinstall DTPros Services, because when I choose "Install Add-ons" from the Help menu, I get the regular dialog box, but when I click "Install" this crashes DTPro beta every single time.

Anyone else have this problem == and anyone else able to get DTPro's Services to be available under Snow Leopard? (I have sent Devon Technologies an e-mail about this.)
