I want English as default language (FireFox for Mac) Preferences / Content / Choose a language It is set to English Yet on Googling it appears to be Polish

How do I change that ?

Just upgraded from version 17 to 20 to find, somehow, Firefox has taken a step backward in how the download window is displayed.

This is the old one: http://limi.net/media/copy_of_Downloadspopulated.png

Look at all that useful information, File name, file size, URL of site, and time/date completed.

Who thought it would be a good idea to take all that info away when "upgrading" to Firefox 20?

Why can't people just do their job right :-s

Ever since I updated to firefox 20.0 I've been having a problem with firefox. Every time I start up firefox I get a message saying that this is so embarrassing for trying but failing to restore my previous session and it gives me the option to either close the page and go to the welcome screen, or to restore my previous session. My preferences has the show my home page selected, and every time that I close out of firefox, I close the page by hitting the red x, and then I highlight either the firefox icon or the firefox tab at the top of my screen and select quit. I reset firefox twice and that didn't work either.

I am using firefox on both my macs (on is running mountain lion and the other snow leopard. It is annoying that in any fields typing only works upon the first click or ->tab on the field, when I click - for example mid sentence to delete a letter (for example) it does not type and the mac sounds the sound effect of "thump" - when you are trying to type in a non-field. The issue is resolved for that instance when I click into a different field (can be the same tab - for example I am typing into the ebay search tab - click on it a second time (thump - no typing) then click in the address bar, now back to the search - now carefully press the arrow howevermany times I need to get to the desired position or just retype the search string - mightily irritating. Same happens in emails, messages... any field! I really like firefox, after a run in with opera, some trouble with safari (tab support)... it was my favourite, with cross computer spaces... I hope this gets resolved soon.

Am set for automatic updates. Update history shows no updates have been installed. Also get update messages. When I click "update" computer goes into endless cycle of trying to connect

The last couple of versions of Firefox have seemingly been more permissive in the popup allowing. If I go to http://www.popuptest.com/popuptest12.html, all three popups open with a simple window.open() JavaScript call. The only one that gets blocked is when I click the back button. Shouldn't the ones that open automatically be the ones that get blocked? I've gotten quite a few ad popups, and it's making me wonder if window.open() is being ignored now.

Every time I go to my Youtube account and watch my own videos or others an audio (I guess 3rd party) pop up video loudly interrupts with an ad. I've searched the internet and done all the cache emptying and cookie dumping and I have not added any add-ons and it continues to occur. How do I stop this. It is ruining any enjoyment I get from playing a video.

Some websites are broken (DuckDuckGo.com, NASA, Cult Of Mac, Twitter, Google+) when I have a plugin on called MaskMe. It remembers passwords and gives websites disposable emails to stop spamming. It doesn't do anything else, but can someone tell me why MaskMe is breaking websites? Another thing: MaskMe works perfectly fine in Chrome without breaking websites.

about every three times I start firefox 20.0 on my Mac, there is a notice to update. When I click on the update now the window acts like it is starting to update, but will stay there for 20 minutes and no change. Just the bar with seeming activity, but no progress.

On three of my regularly visited websites, Firefox does not ask to remember my password, so I have to enter it each time. On most other sites I visit, it asks and remembers the password. I've gone through all the suggested steps such as starting Firefox in safe mode, troubleshooting extensions and add-ons, etc., but those sites still will not remember or ask me to remember the password. What else can I try?

Forefox 16.0.2 on MAC OSX 10.8.2 with most current Adobe Shockwave Flash will not open You Tube videos. Photo of video shows, it seems to load, but then nothing happens. I have gone through all the suggestions on your site and spent a great deal of time and still cannot reach a solution. This is very maddening, as much as I love Firefox.

Just started today - a file wants to install on my computer "afr.php" from http://cas.ny.us.criteo.com.

I have been getting spam emails from several of my friends today, could this be trying to infect my system?

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.
