Or Ctrl +

Does IE Tab work with 4? Santander always have been crap with updates on this sort of thing...

No. It was one of the plugins I had, and it was rejected.

I stopped using it as it became irrelevant for me personally.

I'd forgotten I'd installed it until it got spat out by the upgrade

Every so often I have a clearout just in case anything is slowing up FF even further

Mozilla puts squeeze on slow Firefox add-ons

Mozilla is cracking down on Firefox add-ons that put an undue drag on the performance of the open source browser.

With a blog post on Friday, Mozilla said that within the next two weeks, it will add a warning to any add-on that slows Firefox's startup time by more than 25 per cent, and in an upcoming version of the browser, third-party add-ons will not be installed unless the user specifically approves the installation.

"It’s an all-too-common practice of third-party software to install toolbars and other bundled add-ons in your browser without permission," Mozilla says. "We know that these add-ons account for many of the performance problems reported to us, and users often don’t know how the add-on got there or how to remove it." Requiring approval for the installation of all add-ons, Mozilla believes, will have a "huge impact" on performance.

Every week, Mozilla will run automated performance tests on the top 100 add-ons in its add-on gallery, and it will display the results here. After the first round of tests, the slowest performing add-on is the hugely popular website debugger, Firebug. According to Mozilla's stats, Firebug slows startup by 75 per cent.

The seventh slowest add-on is FastestFox. It's designed for speedy browsing, but it slows startup time by 31 per cent.

In the coming months, Mozilla will also provide tools to developers that will let them test add-on performance on their own, and it will be contacting developers whose add-ons are putting an inordinate drag on startup time.

"Firefox performance is extremely important to our users, especially how quickly it starts up and loads websites," Mozilla says. "Customization is also extremely important, and while most add-ons cause only a tiny performance impact, others can significantly slow down Firefox. Many users don’t realize add-ons can cause these delays, and that’s why we’re committed to improving performance in a big way."

Eventually, Mozilla says, it will test all add-ons as they're submitted to the gallery, and it will expand testing to page load time. ®

Godamnit, it's all the good ones:

FoxyTunes

Video DownloadHelper

Adblock Plus

NoScript

The only ones I use on that list now are NoSCripts and Adblock Plus. Don't think I have GreaseMonkey anymore, and can't be bothered with VideoDownloader either.

I con't care if NoScript slows it down, I'm still running it!!!

EDIT

I can live with a 16% slower start up time quite easily. CLICKY

+1, but it's still a shame...

I don't like that you can no longer add a Open New Tab icon to the toolbar.
Sure, there's the + next to the last open tab, but I find it much quicker and more intuative if the item I have to click to open a new tab is in the same location on the screen every time I want to use it.

I use that or Ctrl T, whichever comes to mind.

I use Tab Mix Plus (in 3.6 I should add) - lets you duplicate tabs, colour em, shift em around, lock em, open closed ones etc

Can you not just double-click the tab bar?

Also I cannot add a new New Tab button but I can move the button from the end of the tabs to wherever I want it
