That too, yes. I used that when I had a laptop without a mouse.

Jeez...sorry.

Honestly I never really thought of it. I'm sure it goes back to my days with a mouse that had no middle button though.

Ah cool, time to upgrade from the Beta version then.


I just ctrl-click :shrug:

I started a new profile with Firefox now but I'm still getting the weird problem with it showing more than one vertical line for where I'm typing. It's not crashing anymore, I think, and I still see different versions for Java Console in the extensions. Idk if that's how it's supposed to be. All the plugins are also still there.


Useful tip for me, since I use a laptop.

Did you try a clean install of Firefox not just a new profile? Maybe an extention or something got messed up. Just a thought.

So a website I need to access for school seems to have an issue with Firefox 4 because it claims to be an unknown version. Is there a way to force compatability or somehow trick it into thinking its an older version? I have been using Opera for it but that seems clunky and interrupts me since I browse other tabs at the same time. I don't want the IETab extention as if I recall that actually uses IE to render the pages, though I could be wrong.

I have the same problem now (and I'm on a laptop so I can't middle-click). It's almost entirely why I didn't switch to Google Chrome. That and I feel a sense of loyalty towards Firefox.


I encountered that problem with a website as well. It also had a problem with Google Chrome and so I was forced (totally against my will) to use Internet Explorer. I can only imagine that it's because it's so new and different from version 3 that websites haven't added it to their approved/appropriate browsers list.

https://addons.mozilla.org/en-us/firefox/addon/user-agent-switcher/.

That'll fool 99% of sniffers. Of course there could be a legitimate rendering issue, which that won't fix (but I doubt there is a legitimate issue)

Can you guys check how much memory firefox takes? (ctrl+alt+del)

It's taking around 700,000k for me. Right now it's 1,261,900K!!!

I've got 6 tabs perma opened, however I don't see why it should take so much memory, they're all forums like this + facebook.

EDIT: I closed FF and now it's down to 200K. Still, isn't that a lot?

EDIT2: Chrome goes up to 60K at most.



Also, Adblock plus doesn't seem to be working. Some websites still show me their ads, where as before the upgrade they wouldn't be there.

Firefox's memory usage is sitting at around 150,000 for me (a couple of tabs open, Win XP).

Adblock Plus is working fine here - perhaps try updating your addons, or your Adblock subscription (although the latter, at least, should happen automatically).

Make sure you have an active subscription for adblock, when i first installed it it said it failed to download the list, i just tried again and it worked.

also, FF open like all day and im at 270,000k

What is active subscription?

I've got the ABP red stop sign on my toolbar though.

You can use ABP without an active subscription. Basically you define your own by manually creating it whenever you block something. Downloading a subscription is just a base to build upon your own custom blocks.

http://easylist.adblockplus.org/en/, http://tinyurl.com/au8fcy.

Click that icon and then go to preferences, should be some option there. w/o a sub it wont auto block any of the ads.

Ah thanks guys. I've added easylist.

Me and my bazillion tabs, including one that's streaming video, are sitting at almost 750K of memory. That's after FF's been open for six hours or so.

I tried uninstalling everything it lets me when I uninstall it, and reinstalled, but it still has the same things in the extensions and plugins, also with the same problems, and freezes sometimes too.

edit - spelling

edit2 - I deleted the extensions and plugins folder in the directory and now I don't see Java Console anymore. Working okay so far.

edit3 - It still freezes.

Seems to not have worked for me.The website for my school actually uses the Blackboard learning system which keeps tellingme there is a sessionalready running which there is not. Works fine on Opera 11 though. Guess I can just keep using that for it.

I just discovered a bug (AMD GPU driver related. Using 11.3) I didn't have with 3. (But I also didn't use this driver.) When I start FF 4 both my GPUs hit 99% usage and stay there even after closing the browser. That's even this page, with no flash video or anything of the sort.

AMD have not made their driver FF 4 friendly yet. (Apparently.)

If you also suffer this, go to Option>Advanced>'Use hardware acceleration when available' and un-tick it. Problem solved til they sort this issue out. (Nvidia has also been effected at one time or another so it's not just AMD.)
