breaks FF 52 Rated 2 out of 5 stars

After updating to FF52 you won't be able to open any links in a new tab. You won't be able to use bookmarks and a lot of menu items either.
You'll have to run FF in Safe Mode and disable this addon. Or download firefox 51, install it and disable auto-update.

[Chinese description]
更新至 Fx 52,MClick 會讓 Fx 的分頁跟視窗記錄(即 sessionstore.js 這檔案)被洗白,無藥可救,只能先停用 MClick,或不要升級到 52 版,另外還會導致開新分頁的動作異常(畫面不會自動切換到新分頁去)。目前只知道是 MClick 跟 Fx 52.0 一起使用時會發生,但原因不明。


Version:
Firefox 52.0 (32-bit)
MCFT 20.0.20150603.1-signed

Issue:
If you upgrade to Fx 52, you will lose your all tabs/windows history ( sessionstore.js will reset to default ), and couldn't auto-focus to the new tab ( like Ctrl-t or Ctrl-Shift-a or else ).

Solution:
First backup your profile files.
Then...

(1) disable MCFT until bug fixed
(2) or just stopping auto-upgrade for Firefox.
(3) To recover your session, your need finding these files:

(a) (folder) sessionstore-backups
(b) (file) sessionCheckpoints.json
(c) (file) sessionstore.js

(4) rename these folder / files ( for example "~sessionstore-backups" or else you like )
(5) copy-paste the correct "sessionstore.js" file into your profile directory.


*Attention*
Anyway, FIRST backup your profile folder before you do anything.
(Windows 7 or newer) Open any folder then type "%AppData%\Mozilla\Firefox\Profiles" in the address bar, and backup all folders you see (in this directory "Profiles").

I'm keen on this one! Rated 5 out of 5 stars

Provides an intuitive feature.

Disable Tab Mix Plus Rated 5 out of 5 stars

With FF 47.0 you have to disable TabMixPlus (if you have it installed) to get this extension to work, otherwise you do indeed get the same behaviour as noted by nubbel below . It might just be one setting in TMP that has to be changed but I have not had the time to figure out which.

This is still an essential extension overall :)

Does not work anymore Rated 1 out of 5 stars

Firefox 46.0.1, after hold-down I want the link to be opened in a new window with focus, worked before, doesn't work now anymore.
After hold-down it openes the link in two tabs in the background... useless...

Bug or a Feature ? Rated 4 out of 5 stars

"Stay open the menu" does not work if the items are in the root menu :(((
(Firefox 46.01 portableapps clear)

Focus tab after release the button. Rated 5 out of 5 stars

Please add an option to "focus tab after release the button".
So we can stay on current tab until the recently opened page finishes loading.

Very useful addon.
I have a small request. Could you please add an option to select which to apply this(Links,Bookmarks etc.)?
I only want to open links in a new tab foreground while holding the middle mouse button. But for bookmarks, I want it the default method(middle click to open in foreground...no holding).
Right now it seems to affect everything and it also overrides the setting from Tab Mix Plus addon.

If I want the new tab opened in the foreground it's because I want to see it immediately, therefor would it not be more logical to have short-time clicking to open tabs in the in the foreground, and long-time clicking for tabs opened in the background ?
