Feature Request: "Copy to clipboard" button like this addon:
https://addons.mozilla.org/en-US/firefox/addon/swift-selection-search/

great ideas but poor implementation.
when I enable this addon, and then do any bookmark operation my memory usage goes as high as my max RAM.
and bookmark operation becomes very slow. so for example if I copy 400 bookmark from one folder to another folder, the memory usage goes very high and bokkmarks get copied almost one by one and very slowly.
I think this is because I use the feature that uses search engines from bookmarks and the addon searches bookmarks every time a bookmark changes, which is a very bad and time consuming implementation.
the addon should have an option (or a button) to load from bookmark only once, and not monitor bookmarks.

UPDATE:
fixed in new version.
thanks for fast reply.
I already went with another addon though.
because every time I open the menu with right click the icons of my search engines are loaded through internet one by one as if there is no such thing as caching. either have an option to disable icons or cache them or give custom icon support that are not internet dependent.

2nd UPDATE:
thanks for the reply.
I changed my rating of your addon just because you give fast replies :).
if I remember correctly in earlier version of firefox I had addons that you could give '.ico' files as icons.
I think firefox new system has limitation for file storage on profile so you cant easily save icon files and use them but maybe that 'unlimited storage' can be used somehow as a workaround to store icons.
If it is not obvious I am not a developer so I take your work for it.
and thanks again.

Good - but the popup selection source keeps getting included in some of my html edits!
That may be due to some other addon interaction but it is very annoying - so I disabled the popup selection option for each items which included it and I just use feature via the context menu which is powerfully configurable anyway.
I added many custom "searches" - e.g. https://unfurlr.com/?url=~$S$~ , https://toolbar.netcraft.com/site_report?url=~$D$~#last_reboot and https://www.whois.com/whois/~$D$~ ...

Suggestion: An overall master toggle for popup selection on/off would be nice

Hello

I have two problems. No icons are displayed in the poput window.
And there is an extra unnecessary submenu.

Windows 7 64-bit, Firefox 58

UPDATE
Icons are blocked by uBlock.

UPDATE2
Extra unnecessary submenu ➜ Show "Add Search Page" in the menu when right click on a text field

Just perfect! I switched from Chrome recently, where I used a similar, but much inferior extension. This one is among a few reasons why I'm probably not switching back to Chrome anytime soon.
Popup window is a real helper. And I wish Firefox itself had such a flexible and easy way of adding search engines as this extension has.
One minor drawback - it seems that the extension doesn't cache search engine icons, so they are sometimes redrawn one by one rather slowly.

Probably the best of them all, but proprietary.

Firefox has made almost impossible to add custom search engines to the search bar and impossible to manage/edit the search engines that are there. This add-on is very useful! And it uses the search engines you create as bookmarks with the command "Add a keyword for this search". And it's very customizable. Thank you!

Only "critic": when you want to search a word that is inside a text area, it opens a second submenu.

I've been trying to use this addon, by trying every version that is released, but after a few minutes that I enable this addon, I get a huge spike on Firefox memory usage till it uses all my memory available (I have 16GB RAM) and crashes my Firefox or sometimes leaves my window freezed!!! Can you please fix this?!? I'm certain that it's due to your addon because when I left it disabled I don't have this

Since the last Firefox update (58), when right clicking and going to sub-menu, the icons are no longer displayed. Even those whose I put an address in the configuration panel.

EDIT: sometimes it's working but sometimes not. I need to restart Firefox to correct the problem. Not very embarrassing but I have to say it.Maybe there is a latency to load the icons but I wait long time and nothing. And I use the classic version of Firefox 64bits.

Worthy replacement of Add to Search Bar, functionality of course impresses!!! Category Must Have!

Thank you for this useful add-on!
Although I've unchecked "show in the popup window", it always turns back to "checked" after I restart Firefox. Could you check this issue?

It is very convenient to use the "show in the popur window" setting! Why not add this setting to "Resent searches"?
It'll be cool!

P.S. And at the same time make the size of the popur window adjustable (specify the maximum number of columns, and the lines will be determined depending on the popur window filling)

Many thanks for your great work, very useful
But, same issue here with recent updates with FF 56.0.2 (64 bits), I have to stay in v5.5

Awesome customizability to allow for searching anything that can be passed on the URL. Really helpful!

This extension is very useful and I use it all the time. However, there is an annoying bug with the icon popup in the current version - it does not respect the "Open search page in" setting under preferences. Even if you have that setting set to "a background tab" (and not "a background tab next to current tab") the extension opens search results in a background tab next to the current tab ...

Hmm ... actually looks as if even the context-menu does not respect the "Open search page in" setting - it used to in the previous version but I have not used the context menu since the popup was added ...

我好像没有表达清楚我的意思。我是说希望作者可以添加云同步功能，就是说在别人的电脑上下载Selection Context Search插件后登陆自己的账号就可以同步自己电脑的该插件配置。

epic

developer is improving himself thats why i lıked this addon
