I have an ASUS dual core 4GB RAM W7 64bit laptop where FF 15.0.1 runs very slowly & many times hangs up.

When I try SPEEDTEST.net (ST) using FF, my d/l speed is ~2MBS & u/l is ~1.5MBS. And I can tell that ST is running very slowly. The ST page alone loads very slowly. Ping takes a long time.

But when I run ST on Chrome, all other things being equal, I can get 20MBS d/l & 3 MBS u/l speeds. A dramatic difference.

I have reset FF & that helped a little but it is still running about 1/10th the d/l speed as does Chrome. I prefer FF & wondering what else I can do. I also run Charter Security Suite.

Thanx in advance - Bob

I have updated from 14.0.1 to 15.0.1 and when I restart my Mac (OS x 10.8.2) it resets to 14.0.1 and asks me to update again.

A couple of times this happened when I didn't do a complete shut-down and restart so I thought that was the problem. I have since re-updated and done a complete restart, to no avail.

Any thoughts? Thanks in advance,

PDF files not downloaded or displayed i Firefox in version 15.0.1. A white blank page is just displayed. This is reported back to me from many users and not just on my computer.

If I am working on a new email, it can just disappear. If I have saved the email as a draft, sometimes it will disappear but will go back to saved drafts, with or without additional copy. d

I have an iMac where all my booksmarks are and I am trying to sync to my new Macbook Pro Retina that I recently purchased. I followed Firefox directions on how to sync my device. First I went to my laptop: tools > set up sync. Then I went to my iMac, went to the firefox homepage > sync > pair a device > entered the code from my macbook pro. Then nothing. The directions say that it will say "device connected" and will automatically start syncing, but I don't see anything. Finding the recovery key option does not work either. When I go to preferences > sync, I don't even have the option for managing my recovery key. Help?

I just added the Yahoo Toolbar to FireFox. When I did this, it automatically added a Yahoo drop menu to go with the Firefox ones. I have no need for it and want it gone. I'm trying to contact Yahoo, but no luck so far. The suggestions they have in their support Q & A don't help.

I'm having problems with pop up windows in Ebay, they are not coming up, even after I add ebay.com.au to my allowable pop ups, in the Firefox Preferences Menu under the "Content" tab!

I want to add a $1 handling charge to my ebay item and the window just goes grey with a spinning gray wheel but nothing happens, I've tried uninstalling Firefox and reinstalling but nothing works.

Pop ups work in Safari when using Ebay so it's a Firefox issue, can anybody help, could it be the new IOS Mountain Lion 10.8.2?? Any help would be appreciated as this is going to bug me..

I recently updated my OS from S.L to M.L. (10.8.2) and in doing so my firefox 15.0.1 will not allow me to extend the size of my browser window on my 27' iMac much more then a window of about 8"x8" or everything distorts and I can no longer type in any fields or modify any of my tabs. If I shrink my window back down I can then re-establish control of my browser tabs. I have disabled ALL extensions and ad-ons, reset my browser size (cmd+0) and have both "reset" my firefox as well as blown out and re-installed FF multiple times. I can browse just fine using chrome and safari..... ff just will not function as I need it to?

I have Facebook as my first tab, pinned as an app tab, and Google as my homepage on the second tab. Whenever I start up Firefox, I can search Google and every other site, but the URL does not change in the Awesome Bar, just remains on 'Go to a Web Site', so it does not track my history, and does not allow me to go backward/forward through pages. All other tabs work just fine. Also the tab will not be closed sometimes, or Firefox will act like the tab doesn't exist when I scroll through them. Have tried some add-on disabling and I cant find the root of the problem.

Any help appreciated

Am using Mac OSX MountainLion with latest firefox browser. When i go to any web page if a link is provided in a page i cant open it by

            * right click -> Open Link in New Tab

Not even Open with new window is also working Every time i wanna copy the link location and go to new tab and pasting it to open a page.

Why this happening ? How to solve it ?

Noticed this when trying to move on your website, GMail etc so that I can move from field to field (example: To field in Gmail, hit tab button on keyboard to move to Subject field). Tab button non responsive. Safari and Chrome still have this ability. Obviously something has occurred as I upgraded today to 16.0 and yet I was fine in 15.x.

This key is important for speed for daily work. Please advise how I can re-activate it's functionality.

Thank you.

I have a mid 2012 MBP with Retina display. When I try to install Firefox upgrades i Get the message that teh update will not be installed, are you running more than 1 copy of Firefox. This occurs no matter what I try even from a restart. Activity monitor only shows one copy of Firefox running

I reset Firefox to the default and that did not help, I started in safe mode and that did not help.

The address bar used to show a line between search / auto-complete results. Now the line is gone and it's very hard to see the grouping of description and URL and find what I'm looking for, they all blend together. I want the line back! I really wish FF wouldn't make these changes - make them available as an option, not forced.

This issue is not repeated in other browsers, and was not an issue on my old Toshiba laptop which I switched from a couple weeks ago. This problem has been here since I started using a Mac computer (It's a new mac, up to date with the software etc)

The download button at first looks ok until you click on it, its size gets bigger:

Is it a bug?
