Firefox Support Forum

I'm a native Dutch speaker, and also read and write a lot in English. Hence I have two dictionaries installed for spell checking: Dutch and English.

I often find myself using one language on one page, and the other on the next, thus having to switch the spell checker dictionary between Dutch and English all the time.

What would be VERY convenient, is either

1. The possibility to use two (or any number) dictionaries at the same time.

Or better yet:

2. The possibility to 'auto detect' the current language, and use that dictionary.

This auto detect thing could simply consist of seeing what dictionary results in the least number of detected spelling errors, and use that.

Thanks for your consideration, this sounds like a rather simple feature to me, yet I've been missing it for many years, and I have in fact found quite some similar requests from other people throughout the internet as well! It would make a great addition to Firefox!

I continue to see malware called www.chumsearch.com on my search engine and in other applications. Was able to delete it from Safari but I can't seem to get rid of it on firefox.

this started couple months back already, but initially it only affected the "unread all emails" button. i used to be able to click the button with the cursor, but have been unable to do so for the past few months. instead, i have to click it with the enter button. this problem has now affected my google drive, where i cannot create new documents with the cursor. i'm not sure how to explain the problem, but it is unresponsive when i click the buttons with the cursor, however works when i choose the button with the keypads and the enter key. is this a problem with proxy or cookies saved? can anyone help me with fixing this? thanks in advance

Firefox Quantum v. 65 allows the user to block "all cookies (will cause websites to break)". However, a cookie designated "marketingapis.com" continues to appear in the list of cookies whenever the browser is used. When attempting to block the cookie through the managing permissions option, the blocked cookie disappears from the list of blocked cookie list and appears in the regular cookie list whenever the browser is subsequently relaunched. I would be grateful for any advice how to prevent this cookie from reappearing.

If this is a cookie set by Firefox, information should be disclosed upfront, and users should have a method to prevent its use (or opt out) for all purposes.

Your instructions on creating folders aren't correct. for my Mac, saying nothing about having to Open the Bookmarks pull-down menu Select 'Unsorted Bookmarks' Go to the top 'Wheel' icon

THEN you can create a new folder, and other good things Bit of a pain. Otherwise, Firefox is great!

Hello.

Need some help, for some reason the slider doesnt work in firefox on our website http://www.allon4.com.au/.

but it does with all others chrome, safari etc...

any ideas?

if ( document.styleSheets[i].rules !== undefined ) {

                   cssRule = document.styleSheets[i].rules[ii]; 
                   }
               else if ( document.styleSheets[i].cssRules !== undefined ){
                   cssRule = document.styleSheets[i].cssRules[ii];
                   }

the above code causes a security exception when the tab is already open and another page from the same domain has already been accessed. Note that the original access does not cause a security exception. The security exception is on the "else if" rather than the "if" statement. If I kill the browser and reopen the same page the security exception does not occur. I have tried everything I can think of the prevent any CORs based exception from happening.

To recreate this behavior use: https://www.fanaticmasks.com/test/store/index.php?main_page=product_info&cPath=1&products_id=7 The page should not throw the security exception

Alter the url to: https://www.fanaticmasks.com/store/index.php?main_page=product_info&cPath=1&products_id=7 And it does throw the exception.

To my understanding of COR this is the EXACT SAME DOMAIN.

But for some reason, firefox gets upset about css rules access for no apparent reason. I have also used the built in functions to a. clear cache b. clear history (ALL history)

but unless I restart firefox the security exception still fires. This appears to be a browser issue since I used php to prevent CORs exceptions at the server.

My research via google only turns up old solutions that I can demonstrate don't solve the problem. I can trap the exception, but I need the rule in order for my animation to work.

If necessary I can make a small example show the behavior.

I have had problems with a html BASE tag in the zen cart package but I can't see how that would affect this problem, since the BASE tag is in both pages.

I use a Macbook Pro. I have scoured the internet for answers to this adware problem. I have cleared the two add-ons I had on Firefox (I don't like too have too many - one was speed dial and one was the add-to-speeddial button). I have reset Firefox, and then when that option disappeared from the menu (I'm fairly sure that shouldn't happen?), I refreshed it instead, as that was the only choice left to me. I have uninstalled Firefox and re-installed it. I have updated it to the latest version. I have created a new profile, in fact more than one, since it keeps asking me to do this. The Adware is still there -it doesn't appear on all web pages I visit, just most of them. HELP ME SOMEONE?!! LOL It's driving me nuts!

Sometimes, but not always, I will download something from the Internet. It might be an .exe or a .dmg or a media file. Instead of coming through in a usable format, though, it will arrive as a binary file.

Today, there was a warning about a Skype "bug" that caused crashes. The recommendation was to immediately download a new version of Skype. This .dmg came through in binary - I had to use Safari in order to download the new version of Skype.

I'm unable to find a setting to cure the problem, so I'm hoping you can help me out. Thanks in advance!

I have an iMac and a MacBook Air.. Both running same version (40.0.2) of FF... and Yosemite latest...

On my iMac when I quit FF I get a "Clear History Window" enabling me to confirm on exit... I like this !!!

On my MacBook Air I am unable to get this "Clear History" Window on exit.. I have tried all options in the FF Privacy settings with no change.... I just cannot get the same window to activate on exit.

Please can someone help with this as I would like both iMAc and MacBook Air to be the same with "Clear History" Window upon quit.

Thanks allan.mcdonagh

In order to use citrix for remote access I need specific encryption settings. I cant find anywhere in version 41 to confirm or change these settings. I specifically need SSL 3.0 and TLS 1.0 or citrix cant launch apps. How do I change encryption settings for my mac? Thanks

Using 41.0.2 on a Mac Yosemite. In last few days, duplicates of my All Bookmarks folder, with a duplicate Bookmarks Menu inside, are appearing in the Unsorted Bookmarks folder. If I attempt to delete a bookmark or folder from the duplicates, the original is deleted as well. Pretty significant glitch in the program. What is causing this and can it be fixed?

Whenever I use the Hiragana input method for Japanese (Mac) the keyboard freezes up every other time I try to type. After typing one sentence or phrase in Japanese, I need to manually switch to another language, then switch back to Japanese to unfreeze the keyboard for use in Firefox. I seems to get stuck when I am offered to choose between homophonous logographs i.e. 用紙 and 要旨, and although the arrow keys work to toggle between different choices, 'enter' nor 'space bar' will register, thus preventing me from naturally exiting the drop down scroll and moving on. This problem only occurs inside Firefox, and only with Japanese Hiragana (Chinese Pinyin works fine ironically). In Safari and other browsers the input method also works fine. Thank you for answering my question.

I am doing security research to benefit the mozilla community and it's users and in order to lower costs I'm trying to do research on the Raspberry Pi 3. I am following this guide https://developer.mozilla.org/en-US/docs/Mozilla/Testing/Firefox_and_Address_Sanitizer specifically the manual build section.

I have three web browsers on my MAC Book Pro, and only Firefox is becoming corrupted. A week after installation I'll find that google.com no longer is my homepage (even though I've indicated it in preferences.) What appears to be another browser (centurylink.com) will appear listing hits like it does on google. I've gone to Century Link and deselected all if its services so that this doesn't happen - but it continues to happen. I uninstalled Firefox because Century Link said it was corrupted, and reinstalled it, and the same thing happened again after a week. I don't know why this is happening. Right now, I have Firefox uninstalled because I think it's a security risk. None of this is happening on the other browsers, by the way: Safari, Google Chrome.

Thank you for responding to this!
