I don't know when it happend first, but when I open a video on youtube with Firefox 6.xx, I always get a window (title "Javascript Application") with the message "Error: Div is null".

I tried upgrading to FF 7.xx beta, and also 'downgrading' to FF 5.xx again, but the error still appears. When I disable Javascript, the error doesn't appear, but this workaround can't be the solution.

Previously this seemed to driven by an addin which I removed. Now each time Firefox updates itself every 1-2 days this problem reappears without the original addin. Because the chinese characters float over the top of the tab name it makes it difficult to read the tab name is is plain irritating.

This isn't as much of a support question as a design decision question. I know that WebM is to remain open, and h.264 isn't sure, but from what I can tell from these results:

http://www.streamingmedia.com/Articles/ReadArticle.aspx?ArticleID=68594&PageNum=1

The CPU usage difference is immense, which honestly is an issue for a lot of PC's. h.264 is way lower on CPU usage, and seems to be superior overall. Are there any plans/talks to move that to being an open standard, and will Firefox ever support it?

I understand Firefox is an open source browser, but that doesn't mean it shouldn't support some standards if they are as dramatically superior as this, even if it wont always remain open, drop it at that time instead of just not picking it up.

I visit sites that have local ssl certificates installed (self signed), typically I get the warning about this, accept, confirm, etc. All used to be good. I just now received an update to FF to 33.0, now none of these sites work. (I'm in the Beta channel) I'm getting: error code: sec_error_invalid_key

The sites in question, are all mine, and work well on other browsers.

I reinstalled FireFox, and the built in PDF reader is a piece of junk. Notably, it forces me to download EVERY PDF, regardless of using your junky PDF viewer or the Adobe Acrobat (I have the Full version of 9.5). Everything worked perfectly until you decided to include a PDF viewer in your program.

I have tried everything to make it work. So, since I cannot get any support from Mozilla for the product, I am switching to either Chrome or Safari. I have been using FF for years, but I guess you seem to think that you know what I want better than I do, so I am dumping FF and going elsewhere. You are NOT the only sandbox in the playground, folks. Now I am taking my toys and playing elsewhere.

If you ever decide to start paying attention to the people who use your products, perhaps I will return.

In Firefox 19.0.2, and in Firefox 20beta4, I have an issue that my "add a new tab" button keeps disappearing when I customize toolbars.

No problem, I can just do a customize, find the new tab button, and drop it right next to the last tab, right? Wrong. It doesn't allow you to drop it there, only all the way to the right.

This leads to a situation where the "+" appears when I am customizing toolbars, but is not visible once I finish customizing.

I can restore it by doing "restore default set." But then I have to start over on my customizations.

When it is all the way to the right, it is supposed to pin to the right of the last tab, right? But dropping it there creates a situation where the "+" simply doesn't appear in the regular interface.

Again, "restore default set" fixes the issue, but how can you drop it next to the last tab, or have it not disappear if you drop it all the way to the right of the tabs?
