^thank you, Tuxman  but I disabled GreaseFire and GreaseMonkey, because I only found a couple of scripts to (not) use.

Yes, but you can enforce it.

According to some, Firefox 43.0.4 is The Last Firefox to allow unsigned addons. I have but a few of the kind, so I wonder what may become real life when Firefox 43 is in the past; Am I to lose a lot of addons, or never update, or...?

And what is all this imitation of another, inferior browser. How weird behaviour is that? Are "they" planning to merge Mozilla and Google?

Will Firefox have a future as my browser, or even as someone else's browser? 

Does anyone use SearchWith

I don't quite understand how to manipulate the configuration.  If I SearchWith Web then it just seems to do a Google search.  I don't see the "each engine results in its own tab" that the author talks about.  Maybe it is too easy and therefore over my head.  I'm a bit baffled I must say. 

Edit:  Ok.  I get it.  If other than the default engine for the category is desired one is supposed to press Shift yadda yadda.  Not a bad AddOn.

Well, the D.E. is pretty much an "unbranded Firefox", so the usual ways to deny Firefox's automatic upgrades will probably work here too.

Use the Classic Theme Restorer.

Use the Classic Theme Restorer.

When using this I found Theme Font and Size Changer handy.  I don't run a multi-tab AddOn so the changer is handy to set the tab color and font to make them readable after changing to the classic theme.  It can also make menus easier to read without resorting to reading glasses or the Windows magnifier. 

Hi .. late to the party and have a lot of ketchup. (Wait, I did this back on p. 27, well it helps me review.)

Application: Firefox 43.0.4 - Win 7 Professional

These 12 I know I use and like and a few of them are why Firefox remains my #1 browser, even while I have learned to be a bit more conservative on open tabs. I used to shoot for 75-100, now I am happy with 20-50, and often less.

- Tab Mix Plus
- Roomy Bookmarks Toolbar - thus I use this as the hierarchichal adjunct to the superb Linkman keywords using regular bookmark-to-toolbar adding
- LinkmanFox
- LastPass
- Lazarus: Form Recovery
- Session Manager
- All-in-One Sidebar
- Download Manager (S3)
- Extension List Dumper 2
- Restart My Fox
- WikiWand: Wikipedia Modernized
- Flagfox

No tab count extension at the moment.
Page Rank seems neat, it is included in the robust Flagfox as opening tabs.
Various tools that make phone numbers hot.. I go back and forth .. Skype is not thought to play nice.

==================================

This next group I think I might use some, this is a tricky specialty area now:

- Docs Online Viewer
- Google Docs Viewer
- Open in Browser

Plugin- PDF Xchang Viewer

==================================

These relate to gmail - I am also looking at a website's tools called Hiber, this is a specialty area as well and I am actually not sure where I stand.

- Rapportive - (gmail) Making email a better place -
- Vibe for Firefox - Rapportive for the web. Hover on emails, and get complete information about people

==================================

There are various biz tools I consider, one was:

SEOQuake

but I think it did so much on my google searches that google started to ask me to be sure I am not a machine.

==================================

AdBlock and NoScript and such I have mixed feelings about, right now they are not on, I may go back and read your experiences, I would use them more for speed than security. At the moment, by reducing tab usage with some of these other tools, rendering is quick. I find that Firefox up to about 30-40 tabs and another 5 on Chrome and a bit more elsewhere is ok.

==================================

Here are nine that I might be conceptually using, but not in praxis.

- FlashDisable
- iMacros for Firefox
- Personal Titlebar
- ProfileSwitcher
- User Agent Switcher
- Send Tab URLs - to email or clipboard.
- Super Start - Speed dial, simple todo-list.
- Tab Set Saver - a good extension idea, that needs a couple of tweaks added to make it really useful
- Textarea Cache - it is meant as a possible supplement for Lazarus, which does not do Facebook.

===========================================

There are certain areas where I use Chrome, google stuff and it has a very easy pin-to-taskbar (something I recently learned and like), Use Chrome for google hangouts, ongoing Facebook conversations, Live365 (ending soon), and other stuff. The lack of Tab Mix Plus multi-row is the big limitation. 

And I have a bunch of other browsers installed, PaleMoon in my Linkman "user defined" and has TabMixPlus, Lazarus and more.  Vivaldi and Opera and IE have a small place and I installed a few others for play.

Steven

Random hint:
Pale Moon 26.0 is here.

thanks, updating

Firefox 44.0 is here as well.
One extension out of 13 disabled by the version 44 update.

^DoNotTrackPlus
(was disabled by Firefox 44)

tbh I often install an extension on e.g. a recommendation here, and then simply completely forget about it unless it gets in the way.
Cant say I noticed if this one (DoNotTrackPlus) was doing any good or not.

Vibe for Firefox -    Rapportive for the web. Hover on emails, and get complete information about people

This sounded interesting and I gave it a try for a couple of days. But it seemed to hold one CPU core completely busy, and killed browser responsiveness, so I had to kill it.

Theme Font and Size Changer

I can't seem to get the Theme Font and Size Changer to work.

Do you have checkCompatibility installed?
