My Reviews

Lightbeam for Firefox

Crap! Rated 1 out of 5 stars

Produces No 'data' or 'graph' ...
clicking 'feed back' goes to Google (sucks) and for an appellate called 'Collusion'
No access to 'options'
Does Nothing in Aurora 30.x

This review is for a previous version of the add-on (1.0.9). 

DOM Inspector Plus! [dm]

I like being able to Scroll right to see vlues of previously 'empty' ID's Rated 4 out of 5 stars

Nice, works well and loads quickly.
some sub elements (id's) need to be double-clicked as expand tree > arrow is nested in id and does not expand when clicked.

Inspect Context

Nice. 'Inspect' both page and UI (chrome) elements in one add-on Rated 4 out of 5 stars

This Add-on replaces some others: Element Inspector, Inspector Widget and ....
Because this Add-on is fired (started) from the right-click context menu and not a button, it is easy to 'inspect' elements in a menu or sub-menu of the chrome UI (firefox user interface)... But.. to 'inspect' the context menu it's self, you'll still want to use the icon launched (using Shift+right-click) DOM 'InspectorWidget'. This add-on tries to do it, but it's not as 'good' at it.
Well done.
ps. I'm not saying anything bad about the others. They work and I have and do use them...

Element Inspector

Exellent, Thank You. Rated 5 out of 5 stars

I had 2 icons in my main context menu with no label. Could Not figure out what 'put them there'. DOMi, as you know doesn't give you a second click, even with Addon InspectorWidget installed. This works. I was able to figure out that Scriptish had put the icons there... ~/scr/scriptish/icons.... Even though I had not installed any scripts or styles with Scriptish... Hmmm. Australis sucks...
Anyways, this helped greatly and, for now, I disabled scriptiish..


Eliminates need to load chrome file Rated 5 out of 5 stars

Totally Awesome.
Eliminates the need to have to figure out which part of chrome:// to load, to be able to 'select' element in normal DOMi...
This causes chrome to load instead of url of page being viewed.

Sidebars List

Thank You! Rated 5 out of 5 stars

i was looking for a 'button' to activate BM sidebar, but this is nicer. It collapses sidebar instead of closing it each time.
With the collapse instead of close option, i don't have to retrain myself to click margin instead of close 'x'... Nice.
Thanks again, Landis.

Developer Tools - toolbar button

Good looking twist on Dev Tools button Rated 4 out of 5 stars

Nice job. I like many things about your menu 'button' (dropdown).
one is that you use my desktop theme colors and not the lightweight theme, grey bg..
The addition of the Repositories is a nice touch, too.
Even your icons look good.
Oh, and it Works well in Nightly builds...

FT DeepDark

Love this Theme... Rated 5 out of 5 stars

I've been looking for a replacement to my 'old' fav Office Black...
I Found it here, in FT DeepDark..
Authors' other theme, 8 Ultimo is also very nice. I used to use pre-O.B.
This theme works Very Well with KDE and GTK2 engine, Transparent Oxygen, Caledonia and my edits..

A few details I Very Much Like:
1) the top and bottom margin / padding between toolbars, menu items and Especially in the Bookmarks menus, makes me Very happy. This means more lines (BM's) visible in menus.
2) i like the fine detail of the Text only, highlight of blue on tab hover.. classy.
3) i'm not a fan of blue, but this is an elegant blue [#00adee, ( rgb 0,173,238 )] and a good enough choice that i substituted it for my KDE Qt select on focus and hover highlight color to match. Matching my Qt (KDE) theme and this themes GTK+ theme.. (All my stuff is already dark, but was using hard to see grey).
4) -- well, I could go on, but No one is going to read this far anyways... so...

Merci beaucoup.
p.s., I actually installed from Steva's home site:

Session Manager

Very Useful Add-on Rated 5 out of 5 stars

I've been using SM for a year or so and have found it Very useful. At anytime, I will have 4-5 windows and 200 tabs open working on different websites, researching, working on code... Bookmark All Tabs, Only BM's the primary window and Not tab sets.. Session Manger Does!
ps. session 'titles' are stored in flat files while data is stored in sqlite.. Nice.

About sessionstore

Sweet... Rated 5 out of 5 stars

Nice add-on...
good layout and fast.
Thanks, Landis.

Spell Checker

Excellent Add-on Rated 5 out of 5 stars

I write sites, live in kate (KDE utf-8 text editor) via konqueror (KDE file manager) using sftp connection to server. Checking code pages, 1, 2,000 even 10,000 plus lines long, is tedious with all the 'special characters' that are involved in html, php, css, javascript etc... So, i don't check.. This takes the 'code' out of the picture by checking the generated page... Awesome.

*one request would be either use a larger dictionary or a way to add words that appear on a site, repeatedly, to cut down on the highlights...


User Agent Switcher

very Useful Rated 4 out of 5 stars

i've been running linux nightly builds of ff for years and too many site 'developers' ("webmasters" lol) just don't get that 'everyone' are not running windows internet exploder, So 'spoofing' your useragent (UA) is is very helpful as a workaround to both these issues.
(*note, we used to be able to accomplish this in about:config > general.useragent* , but in Gecko 2x, FF higher than 18 (27.x) does not support UA overrides, that I have found... )
Thanks, Landis.

Personal Menu (Personal Firefox Button)

Awesome, Спасибо! Rated 5 out of 5 stars

Decent Addon! Rated 4 out of 5 stars

works as advertised and is very useful as most sites don't have a VK share button.
Thanks, Landis.

Developer Tools - toolbar button

I like this 'button' Rated 4 out of 5 stars

thanks, much easier than firefox menu, Plus you still have access to Error Console, something that has been removed from webdev tools menu...

Hide Tabbar

Rated 4 out of 5 stars

pretty sweet (nice job).
i use openSuSE and KDE so i can hide (disable) title bars and borders for my windows or a window or app. i wrote addon for hiding navbar and bookmarks bar, now i don't have to right one for tabs.
my 'web page is now windowed at 1024 wide and literally top to bottom without 'full screen'...
Thanks, Спасибо
one recommendation. enable or activate area could be larger or definable as i run my 'taskbar' at top of desktop and use autohide on it. i have to go so high to enable tabs bar, i am activating my taskbar and it covers the tab bar... just saying. again, good job.


Rated 5 out of 5 stars

this is a Must have!
I've tested many times and I don't see any, .net, fbc* urls being loaded in my status (activity) bar.
Thank You, Спасибо.
ps, the problem i was looking to eliminate was the failure of pages fb apis, links to load when fb was down, busy, etc.
I hate facebook, youtube and google.
thanks again.
