Awesome, and in my native language I'll say : magnifique ! Rated 5 out of 5 stars

Works fantastically well in my Thunderbird (actually version 14) with >>ALL<< my search engines installed on Firefox ! (it links DIRECTLY to my french Google, image Google, Bing, Yahoo, french Wikipedia, french Amazon, american Amazon, french eBay, Youtube, WordReference, etc.) simply by setting the max number of search engines in the extension... to my 10 prefered engines I have installed in my Firefox.
Thanks also for the ability to link to dictionaries. In this part, I'd like to suggest a link to the very known WordReference (if you don't know it... it's a dictionary online for the 15 most used languages in the world and it also includes the totality of the prestigious Oxford Concise English Dictionary (see http://www.wordreference.com/definition/) and one of the largest thesaurus and one of the biggest synonyms' index and a three language verbs' conjugator ! And all that can by freely assisted, on demand, by linguist helpers (some of them are even professionnals) in internal forums ! I'd like to have this very known WordReference in the list of the direct dictionaries. Possible for a next release ?

This review is for a previous version of the add-on (0.7.4.1-signed.1-signed). 

Thanks for the good review! Appreciate that. Next release is almost ready (with fixes for Google and Yandex translations, they changed a format again). I'll try to include WordReference to the next release (that depends on the availability of API or parseability of web page)
Update: Wordreference added, will be available in the next version

Google changed it one more time. New version which should fix the issue was just released.
Please use support site for report issues, I prefer issues reported on the support site rather than non-5-stars reviews.

I love this addon! Thanks for created this. It really help me a lot!
A little suggestion, could you add option to remove the status bar or drag it to somewhere else? :-)

Thank you for the good review. Such option already available, please open preferences, go to behavior\miscellaneous\ and uncheck 'show status bar icon'

Excellent add-on, works much better than Auto Context, which I used to use. SelectionSK is actively developed and the author actually responds and fixes requests/bugs. I appreciate all the features and options available, as well as the tool tips with detailed info in the options menu. One of my necessary add-ons that I install with Waterfox.

Organize Search Engine Support? Rated 5 out of 5 stars

Thank you very much for this addon, I finally found a replacement for Auto Context. Is there anyway you could add support for the extension "Organize Search Engines"? https://addons.mozilla.org/en-US/firefox/addon/organize-search-engines/?src=search

When I go to select a search engine I have so many installed it's a pretty long and messy list. Organize Search Engine makes it much more manageable. Thank you!

This review is for a previous version of the add-on (0.7.1-signed.1-signed). 

Such support is actually provided by "Organize Search Engines" extension. I sent a request to the author of extension, will be glad to make any required changes on my side.

Rated 5 out of 5 stars

I installed this because of the option to use Bing Translator, which pops up with a translation right by the text, as opposed to Google and others that open a whole new tab to view a translation. This is much more convenient if you only need to translate a word here and there. The highlighting and other stuff is an added bonus, and it's been working fine (I had no trouble using the backspace key with selected text).

One minor suggestion: sometimes the popup menu gets in the way of the text that I just selected which is a little annoying; it you could somehow configure it to appear completely above the text that would make it even better. But otherwise I'm completely happy with it.

This review is for a previous version of the add-on (0.6.1-signed.1-signed). 

Thank you for the good review!
Popup position actually controlled by FF. Can you please report the issue on the support site and provide more details, maybe even screenshot, I'll try to correct the issue.
Update: in addition, v7 has 'popup button' option instead of popup, it may satisfy you as a workaround.

Rated 4 out of 5 stars

Nice and smart tool! Thank you very much for providing this.

I have only one thing that I don't like about it. When I am writing e-mails and I select text, I can't use the backspace and that is a bit annoying - sometimes.
Another thing is that I don't see a highlight, when I use the highlight function. Thunderbird 9.0.1
One more issue is the display of translation text.
I am currently translating into German and a result is showing like this: WörterbuchAdjektivendlos, unendlich, unzählig, uferlos
The first word are actually 3 words. The tranlation actually starts after the Words WörterbuchAdjektiv (what means Dictionary Adjective) and for some reasons the spaces or swallowed. That makes it a bit hard to read.
If I try to copy the translation into the clipboard by selecting the text and trying to use the right mouse click context menu, the translation window just closes before I can copy it. The shortcut CTRL+C works.
Just as some feedback.
I like the extension anyway.
Anything else is fantastic!

This review is for a previous version of the add-on (0.6.1-signed.1-signed).  This user has a previous review of this add-on.

I'll investigate issues reported by you and will try to fix them. Can you please provide more details about translation issue (like source language, destination language, exact phrase, expected result)? I'll appreciate if you will use support site.
Update: issue with context menu in the translation window fixed; highlight issue fixed. I cannot reproduce translation issues so far.

The first letter always appears twice whenever I type in webpage search boxes or reply boxes. Please get it fixed.

This addon gets active only when text is selected. Maybe issue caused by other addon or there is interference with other addons.
If you still think that issue is caused by addon than please provide more details (addon version, browser version, OS, steps etc), would appreciate if support site will be used for bug reports.

This is actually not an extension issue, but limitation of mailto: protocol and lack of functionality on the email client side. For example, for Outlook following needs to be done:
- open Internet Properties
- go to Advanced tab
- scroll down to International section
- check "Use UTF-8 for mailto links"
I'll check if I can workaround that for other mail clients.
Also please use support site for report the issues.

I added FAQ about the issue, please see https://bitbucket.org/ashemetov/selectionsk/wiki/FAQ#!send-to-mail-recipient-copies-garbled-text-instead-of-selection-for-non-enlish-locales-how-i-can-fix-that.

please make your "search with" to use "Organize Search Engines" structure

What is "Organize Search Engines" structure? Are you talking about "Manage Search Engines" option available in the Search Bar? If yes, than addon is working with it seamlessly.
If you think it can be improved than please use support site.

beta 8 Rated 4 out of 5 stars

SelectionSK 0.5 Beta 8 - you add "itema from FF menu can be added to the addons menu" but I think you chose the hard way ... because this option dont support custom sorting for example from extension "Menu Settings", dont suport extension "SmartSearch" (for now) ...
Please simply add the option like in AutoContext where You can choose which context menu to display - Your or standard Firefoxes :) and I'll give you not five but SIX STARS!!!

This review is for a previous version of the add-on (0.4.1.1-signed.1-signed).  This user has a previous review of this add-on.

Custom sorting is supported for regular items; I am going to add a support for additional items as well.
SmartSearch doesn't work because its menu item doesn't have a label; I sent an email to author and implemented generic workaround on SelectionSK; feel free to check new beta.
Show global context menu is not an option for now - first, global context menu has a lot of unnecessary items; second it replaces SelectionSK menu and, basically, eliminates all SelectionSK functionality which doesn't make any sense for me.

The search box needs to be on the toolbar for the search highlighted text function to work. As I'm using keywords in the address bar to search then this is pretty much useless for me right now.Please add the function to search by keyword searches and you shall get 5 stars!

This review is for a previous version of the add-on (0.4.1-signed.1-signed). 

Well, the issue was already reported and already resolved - please see issue #24 on the support site.Please download the latest beta from the support site or just uncheck "Copy selection to the Search Bar" option.
Also, please clarify the request "add the function to search by keyword searches" - not sure I understand what the request is. Would suggest to use the support site for new requests and bug reports.

Must have add-on Rated 5 out of 5 stars

Dude, you have an awesome extension here! I was using auto-context after hacking it to work with new versions of Firefox. But SelectionSK is even better! I appreciate you responding to and addressing the other requests here in the comment section. Keep up the good work!
