Recently upgraded to 4.0b6 and Firefox keeps on crashing. It starts out by getting progressively slower and slower, then freezing for a few seconds, then just crashes and all tabs close. On restart everything is mostly saved and I can continue working, but it's impossible to work this way. I doesn't seem linked to any specific site/action.

I have spent a fortune on technician to find malware/viruses and optimise my laptop, but it doesn't seem to help.

I am trying to set my home page and specify which pages open when I start Firefox. I dislike that the pages I had open last time automatically open up. Sometimes I close FF to get rid of unwanted pages and it annoys me that they all open back up when I restart FF.

I must have hit the 'group your tabs' feature by mistake and now I can't get it to stop grouping my tabs. I really hate this feature, don't want to use it because I don't want them grouped and for the life of me, can't figure out how to shut the darned thing down now!!

I have restarted, disabled and reenabled all of my addons, renamed the localstore file and still can't find a way to stop it.

I'm guessing there might be a switch in the about:config area, but I don't want to mess with that unless I have instructions.

Please help...

Dell Inspiron 1545 Laptop, Windows 7, Firefox 4. I'm hoping there is a short cut or at least some way to get out of full screen without restarting Firefox. Once I pressed f1 and the task bar came back. But I tried f1 again many times in full screen and I didn't get the task bar back. ( the screen goes dark for a couple of seconds and comes back.)

I figured out how to get out of full screen, by reducing the window size. Is there a short cut to get in and out of full screen?

We (the users) used to have "browser.tabs.tabMinWidth" working in about:config but now it is not working anymore. Setting browser.tabs.tabMinWidth to zero let us have tabs showing only the icon, allowing for a lot of tabs being visible at the same time for fast navigation.

Having to load an addon to change tab width (assuming such an addon can even do that now) seems counterproductive.

I am developing a website in asp.net and html 5 and trying to add some audio to the site.

My site is:

http://www.kevinroseworld.com/music.aspx/

It is, currently, a very simple set up, just the one song. It works fine in Chrome and Safari, IE does not support the Audio tag and the message appears where it is supposed to, however, Firefox does not display the error message or play the audio file.

I started using FF 3.6.10 and have now upgraded to FF 4 Beta 6 and neither version works.

Any advice as to how to fix this?

I also had a look on other forums and found others with the same problem: http://www.manifestmusicproductions.com/soundsNonflash.php for example, works in Chrome/Safari but not in FF.

I am on Mac OS X 10.6.4, Snow Leopard on a Mini Mac a year old. I got a message from X Marks telling me they were shutting down. As I use my bookmarks every day and have thousands of them all sorted into folders I definitely never want to lose them or lose access to them if my house burns down or my computer is stolen! I was using Firefox 3.6 and followed X Marks advise and downloaded Firefox Sync...but...won't work....kept giving me the 'Error While Syncing' message after trying to sync for a while. I looked at the blog and tried a few things like resetting password, restarting computer, checking my setting etc., but no deal. So, as the Firefox Sync download page told me that if I was using Firefox 4 beta the feature was built in and I didn't need the download, I then downloaded Firefox 4....which has removed my X Marks option, which was at least viable till after Xmas! and I still have the 'Error While Syncing' message beside the Sync button on my status bar....so now I am completely at a loss. The only thing I can do if I can't fix it up is go back to 3.6 and go on using X Marks while it is still available and pray that you get this sorted out before they dissappear. I also like to be able to get my updated bookmarks on the other browsers I use, like Chrome and IE, so I would really appreciate it if you would include this cross browser sync capability as soon as you can. I have pledged X Marks that I would even pay for their service to continue as it seems they are so ahead of anyone else in their service and it is a large pain in the you know where that they can't keep going. Thanks. and I hope you can help. From the blogs it seems that I am not the only one having this problem of getting the Firefox Sync working

FF 4b6 isn't able to run my business web site containing Java App. Firefox 3.6.10 and Safari 5.0.1 are working well.

FF 4b6 shows the Java symbol (a cup of coffee) and then nothing happens anymore. If I disable the Java Plug-in FF 4b6 even doesn't show the Java symbol, nothing happens.

My understanding is that Java is NOT handled directly by the browser (Mac) and the Plug-in is just there to hand-over the Java App to the JVM of MacOS. So, why doesn't it work with FF4?

Thanks for any hint in advance.

Kind Regards

i had my bookmarks tab set up to show no names of bookmarks just the icons, the button is still there but i cant see any icon, the link works fine, the only issue here is the icon does not show so i cannot decipher between the links unless i hover over each button and wait for the message details

In Firefox 4 printing seems to have changed in a way that negatively impacts PDF printing. I use PDFCreator an open source PDF printer. Changes to Firefox 4 seem to make it impossible to pass of text to a ghostscript style PDF printer rather it hands off all the text as images which makes the PDF files much larger and none searchable. Is there a way to disable this behavior in Firefox 4 so that works like it did in 3?

PS This problem seems to impact all PS2PDF/Ghostscript based PDF printers/virtual printers including PDFCreator, CutePDF, BullZip and others
