Comment 160 for bug 187313

Well, "work" isn't exactly the word for Mouse Gestures Redox 2.0.3 and me.
I installed it as prompted by Tools|Add-Ons|Get...|search|install.
I saw a positive result, but not the other users of this computer :-)
I looked for system wide installation, rather than repeating this
installation 10 times under each user's Login. I wonder why Mozilla
hates a "Global" option in the installation they suggest. Same for
trying to have people without the right install automatic global updates.
So..., according to their instructions, I had to uninstall what I did,
restart Firefox (total of 5), I was forced to lose my tabs in the
process, and I chose one of :
- either copy an xpi file to some system folder, which was not
guaranteed to work and could ruin my Firefox installation, they say
- or type at a Terminal prompt :
firefox -install-global-extension mouse_gestures_redox-2.0.3-fx+tb+sm.xpi
Nothing happened, not even a message.
I looked for another bug until I figured by myself that a system change
needs sudo...
 From then on, the other 10 users were happy, but not me.
Everytime I started Firefox, I was losing my tabs again, as well as my
home page, and MGR was there waiting for me with a dialog to do settings
it wouldn't remember.
I finally rebuilt an empty ~/.mozilla/firefox/xxx directory and it was OK.
But, without any apparent reasons, it just started that game again.
That's my 4th firefox directory, oh well...

Regarding right-click, the problem is solved indeed.
I use a slow computer (and I am under the impression that low speed is
aggravating the problem, reason why not everybody returns to Internet
Explorer, but no one ever commented that impression).
This make me have the feeling that the problem depends of a priority at
which the mouse events (up down) are processed. I used to miss some
clicks despite my kludge (keeping the right button pressed until the
menu appears).
Now, I no longer miss any.
